You may view, print and download the content for your personal or internal professional use. You may not reproduce, distribute, publicly communicate or transform it for commercial purposes without our prior written authorisation.

The TARIC nomenclature and the Binding Tariff Information (BTI) decisions consulted by the Guiex tariff classification agent are public information from the European Commission. You may use the reports generated by the agent for your own purposes, always stating their indicative nature and without presenting them as an opinion of Guiex.

5. Links to third-party sites

The website contains links to third-party sites, such as LinkedIn, EUR-Lex, the AEAT Electronic Office or Google Maps. We provide them solely for your convenience. Guiex does not control those sites and is not responsible for their content, their availability or their privacy policies.

In accordance with Article 17 of the LSSI, we will promptly remove any link as soon as we have actual knowledge that it leads to unlawful content. If you spot one, please write to us at info@guiex.net.

6. Disclaimer of warranties and liability

We work to keep the website available and its content accurate and up to date, but we cannot guarantee this absolutely. Guiex is not liable for interruptions, technical errors or network failures beyond its control, nor for damage that may be caused by viruses or other elements it has not introduced.

The content of the website, including the blog articles and the results of the Guiex tariff classification agent, is general information. It does not constitute customs, tax or legal advice, nor does it replace the assessment of a professional on your specific case. Any decision you take on the basis of it is your responsibility.

The liability of Guiex is limited to the fullest extent permitted by law. This limitation does not apply in cases of wilful misconduct or gross negligence, nor where consumer law does not allow the exclusion.

7. Data protection, cookies, artificial intelligence and security

The processing of personal data carried out through this website is explained in the Privacy policy. The use of cookies and similar technologies is detailed in the Cookie policy. The information security measures are summarised in the Security policy.

The Guiex tariff classification agent is an artificial intelligence system. In accordance with Article 50(1) of Regulation (EU) 2024/1689 (AI Act), we tell you so before you start using her. Her results are indicative and non-binding. Read the full terms in Use of artificial intelligence and terms of the Guiex tariff classification agent.

If you encounter any accessibility barrier while browsing the website, let us know at the same address. We work to make the site accessible to everyone.

9. Amendments

Guiex may amend this legal notice to adapt it to regulatory, technical or service changes. The version in force is always the one published on this page, with its update date. We recommend that you review it when you use the website again.

10. Languages

This legal notice is published in Spanish, Catalan and English. In the event of any discrepancy between the versions, the Spanish version prevails.

11. Applicable law and jurisdiction

These terms are governed by Spanish law. If you are a business or professional, any dispute shall be submitted to the Courts and Tribunals of Barcelona, with express waiver of any other jurisdiction. If you are a consumer, the competent jurisdiction shall be the one that applies to you by law.

1. Controller

• Controller: Agosto & Anguren IT, S.L. (GUIEX).
• NIF (tax ID): B66393380.
• Registered office: Travessera de les Corts, 340-344, E-1, 08029 Barcelona (Spain).
• Email for any privacy matter and for exercising your rights: info@guiex.net.
• Telephone: +34 93 488 50 34.

2. Who this policy applies to

This policy applies to:

• People who visit www.guiex.net and its Catalan and English versions.
• People who write to us through the website forms or by email, or call us using the contact details on the website.
• People who send us their job application or CV.
• People who use the Guiex tariff classification agent.
• People whose data appears in documents that another user attaches to the agent (for example, a supplier’s contact person named on an invoice).

3. What data we process, for what purpose and on what legal basis

This website has no user accounts, uses no advertising cookies and does not profile you. It does not measure its audience today: if we ever enable Google Analytics, it will only run if you allow it. The processing operations are few and limited. We summarise them in this table.

The website forms send your message directly. It is received by our hosting provider (Webempresa, in Spain), which keeps it in a private folder on the server for only a few minutes, until it is copied to the Guiex enquiry log on our own servers in Barcelona. It also reaches us by email in our corporate mailbox, hosted on Google Workspace. If you send us your job application with your CV attached, the file arrives only as an email attachment and the job applications processing applies (12 months). To curb automated submissions we count submissions per hour without storing personal data.

There is no newsletter and no marketing communications: we will not use your email address to send you advertising.

4. Third-party data in the documents you attach to the Guiex tariff classification agent

An invoice or a technical data sheet may include other people’s data: a sales representative’s name, a signature, a sole trader’s tax ID or an address. Guiex processes that data incidentally, as part of the temporary processing of the query to generate the result, allow reconnection and download. It is automatically deleted afterwards. We do not use it for any other purpose.

As we cannot inform those people directly (Article 14(5)(b) of the GDPR), we publish this information here. To keep processing to a minimum, we ask you to attach only what is needed to classify the goods and to omit or redact personal data: we do not need it. Never attach health data or other special categories of data.

By attaching a document you confirm that you are entitled to share it with us for this purpose.

5. Use of artificial intelligence

The Guiex tariff classification agent is an artificial intelligence system of Guiex. She uses the Google Gemini model through Vertex AI, run in data centres in the European Union (eu multi-region), and our own backend on Google Cloud Run (europe-west1 region, Belgium).

In Reasoned mode, the model may search Google Search (Vertex AI’s "Grounding with Google Search" feature) for information the query does not provide, such as the product’s brand, model or reference. Those searches are generated from your description and documents. Google keeps the searches and the context information for up to 3 days to debug that service, without linking them to you, and that log is not covered by Vertex AI’s European Union data residency commitments. Fast mode does not run web searches. That is why we ask you to leave out personal data.

Guiex does not use your data or your documents to train artificial intelligence models, and does not sell or pass them on to third parties for their own purposes. Google does not use Vertex AI data to train its models. To speed up responses, Google may keep some requests in memory for up to 24 hours. As a processor, Google may keep requests that its security systems flag as possible abuse for up to 90 days in the European region, in order to review them.

The result is an indicative proposal. It is not an automated decision with legal effects on you (Article 22 of the GDPR): the decision to declare goods under one code or another is always taken by a person, you or your customs representative. You will find full information on how the agent works in Use of artificial intelligence and terms of the Guiex tariff classification agent.

6. Recipients and processors

We do not sell or pass on your data to third parties for their own purposes. It is processed only on behalf of Guiex, under contract and following our instructions (Article 28 of the GDPR), by the technology providers essential to delivering the service:

• Google Cloud EMEA Limited (Ireland): hosting of the Guiex tariff classification agent backend and AI model (Vertex AI), with data processed in the European Union, web searches in Reasoned mode (Grounding with Google Search) and corporate mailbox (Google Workspace). Contract: Google Cloud Data Processing Addendum.
• Google Ireland Limited (Ireland): audience measurement of the website with Google Analytics 4, only if we enable it and you have given your consent. It is not active today. Data from European visitors is collected through domains and servers in the European Union. Contract: Google Ads Data Processing Terms.
• Cloudflare, Inc. (United States): anti-bot verification (Turnstile) on the agent’s page. Contract: Cloudflare Data Processing Addendum. Under its Turnstile Privacy Addendum, Cloudflare is the controller of the technical signals Turnstile analyses to improve its bot detection.
• Webempresa Europa S.L. (Madrid, Spain): the website’s hosting provider. It processes the browsing data needed to provide the service and receives the messages sent through the forms, which it keeps for a few minutes in a private folder on the server until they are copied to our enquiry log. It does so under its terms and conditions of service.

The agent consults the European Union’s TARIC and public European Commission BTI decisions. Queries to these sources only include tariff codes and countries, never your personal data or documents.

If you load the Google map on the contact page, your browser connects directly to Google, which processes that data as an independent controller under its privacy policy.

We will disclose your data to public authorities, courts or tribunals only when required to do so by law.

7. International transfers

Your data is hosted and processed in the European Union, with these exceptions: Cloudflare is headquartered in the United States, Google may provide technical support from outside the European Union, and the web searches made in Reasoned mode run on Google Search, a global service whose technical log is not covered by the European Union residency commitments. Such access is covered by:

• The certification of Google LLC and Cloudflare, Inc. under the EU-U.S. Data Privacy Framework, recognised by Commission Implementing Decision (EU) 2023/1795.
• The standard contractual clauses approved by Commission Implementing Decision (EU) 2021/914, incorporated in the data processing agreements of both providers.

If you turn on the Google map on the contact page, Google LLC may process your data in the United States as an independent controller, also under the EU-U.S. Data Privacy Framework.

You can ask us for a copy of these safeguards at info@guiex.net.

8. How long we keep your data

The query, documents and report are processed temporarily to generate the result and to let you reconnect and download it. No permanent history is kept. Access to the query expires 60 minutes after completion. Physical deletion is not simultaneous: it happens at the next automatic cleanup, which runs when the service receives a new query, or when the server instance shuts down, since it keeps this data only in its temporary memory. We do not obtain sales leads from the agent. Save the report if you want to keep it.

9. Your rights

You may at any time exercise the rights granted to you by Articles 15 to 22 of the GDPR:

• Access: find out what data of yours we process.
• Rectification: correct inaccurate or incomplete data.
• Erasure: ask us to delete your data when it is no longer needed.
• Objection: object to processing based on legitimate interest.
• Restriction: ask us to stop using your data, without deleting it, in the cases provided for by law.
• Portability: receive your data in a structured format, where applicable.

To exercise them, write to info@guiex.net stating which right you wish to exercise and a detail that allows us to identify you reasonably. We will reply within one month at most, extendable by a further two months if the request is complex. Exercising your rights is free of charge.

Queries to the Guiex tariff classification agent do not require an account and are retained only temporarily. When exercising your rights, provide the query identifier if you still have it so that the query can be located. If it has already been deleted or we cannot identify the data covered by the request, we will explain that limitation in accordance with Article 11 of the GDPR.

If you believe we have not handled your rights properly, you may lodge a complaint with the Spanish Data Protection Agency (AEPD), C/ Jorge Juan, 6, 28001 Madrid, www.aepd.es. We would appreciate it if you told us first so that we can try to resolve it.

10. Minors

The website and the Guiex tariff classification agent are intended for professionals and for people aged 18 or over. We do not knowingly process data of children under 14. If we find that we have received data from a minor without authorisation, we will delete it.

11. Security

We apply the technical and organisational measures required by Article 32 of the GDPR: encryption of communications (TLS), processing in data centres in the European Union, access control to systems, subsequent automatic deletion of Guiex tariff classification agent queries and anti-bot verification through Cloudflare Turnstile. The general principles we follow are described in our Security policy.

12. Changes, version and languages

We may update this policy when the services, the providers or the regulations change. The version in force is the one published on this page, with its update date. If the change is relevant to you, we will highlight it on the website itself.

This policy is published in Spanish, Catalan and English. In the event of any discrepancy between the versions, the Spanish version prevails.

13. Basic information for our communications

If you have arrived here from the footer of a Guiex email, this is the basic information on the processing of your data. The rest of this page completes it.

• Controller: Agosto & Anguren IT, S.L. (GUIEX), NIF B66393380, Travessera de les Corts, 340-344, E-1, 08029 Barcelona.
• Purpose: manage our professional relationship and reply to your communications.
• Legal basis: performance of the contract or service and our legitimate interest in maintaining the relationship and dealing with your messages.
• Recipients: we do not pass on your data to third parties for their own purposes. Our technology providers process it as processors, under contract, in the European Union and the United States, with the safeguards of the Data Privacy Framework and the standard contractual clauses (Google Workspace). We will disclose it to authorities only when required by law.
• Rights: access, rectification, erasure, objection, restriction and portability, by writing to info@guiex.net, and complaint to the AEPD.
• Confidentiality: our messages and their attachments are intended solely for their addressee and may contain confidential information. If you receive one by mistake, let us know, do not disseminate it and delete it.

1. What cookies and similar technologies are

A cookie is a small text file that a website stores in your browser to remember information between one visit and the next or between one page and another. There are similar technologies, such as the browser’s local storage or the reading of technical characteristics of the device, which the law treats in the same way.

Article 22(2) of Spanish Law 34/2002 (LSSI) requires your consent to use them, except where they serve an exclusively technical purpose or are strictly necessary to provide a service you have expressly requested. This policy also follows the Guide on the use of cookies of the Spanish Data Protection Agency.

2. What we use on this website

This website uses two kinds of cookies and similar technologies. Necessary ones remember your cookie decision and protect the Guiex tariff classification agent against automated use. They are exempt from consent. Third-party content, today only the Google Maps map on the contact page, is loaded only if you allow it, and you can withdraw that permission whenever you want. Audience measurement with Google Analytics is not active (section 3).

We do not use advertising cookies, we do not build commercial profiles, we do not share your browsing with social networks and we do not record your session.

This is a summary of what may be stored on your device or read from it:

The gx_consent cookie only appears once you choose in the cookie notice or panel, click "Show Google Maps" or when your browser sends the Global Privacy Control signal, which we treat as a rejection. Apart from what this table lists, this website stores nothing on your device.

3. Audience measurement with Google Analytics

It is not active today. The website does not load Google Analytics and the cookie notice does not offer it. If we enable it, the notice will ask you first and it will work as explained below.

If you allow it, we use Google Analytics 4 to learn which pages are read, where our visitors come from and which content is useful. It helps us decide what to write about and what to improve. We do not use it for advertising or to identify you personally.

None of this happens until you accept. Until you do, Google’s code is not downloaded and no information is sent to Google.

How we have configured it:

• Google signals and advertising personalisation are switched off.
• Cookies last 13 months instead of the two years Google applies by default.
• Data is kept for 14 months and then deleted.
• The Guiex tariff classification agent is excluded from measurement: no use of the agent is ever measured.

Who processes the data and where. The controller is Agosto & Anguren IT, S.L. Google Ireland Limited acts as processor on our behalf. Google collects data from European visitors through domains and servers located in the European Union, and discards your IP address before logging it, after deriving an approximate location from it. Google LLC may access the data from the United States: that transfer relies on the European Commission’s standard contractual clauses and on Google’s certification under the EU-US Data Privacy Framework.

The legal basis is your consent (Article 6(1)(a) GDPR and Article 22(2) LSSI). Withdrawing it is as easy as giving it: we explain how in section 6.

4. Anti-bot verification in the Guiex tariff classification agent (Cloudflare Turnstile)

When you start using the form on the agent’s page, or at the latest when you send your query, Cloudflare Turnstile checks in the background that it is not being used by an automated program, so that only people can send queries. While you are only reading the page, it does not connect to Cloudflare. Turnstile does not set its own cookies, but it runs technical checks in your browser (such as the IP address, the user agent or connection characteristics) and stores a technical identifier in the browser’s local storage, within Cloudflare’s domain. Cloudflare is the controller of those signals when it uses them to improve its bot detection, under its Turnstile Privacy Addendum.

This processing accesses information on your device and stores an item on it. It is exempt from consent because it is strictly necessary to protect the agent’s service against automated use. You will find more details in the Privacy policy.

5. Map, fonts and other content

The map on the contact page only loads if you allow it: by accepting Google Maps third-party content in the cookie notice or panel, or by clicking "Show Google Maps" on the page itself, which counts as consent for Google Maps. Until then the page does not connect to Google. We store your choice in the gx_consent cookie: as long as you do not withdraw it, the map loads by itself on your next visits, and if you withdraw it from "Cookie preferences" it stops loading. When it loads, your browser connects to Google servers, which receive your IP address, technical browser data and the address of our page, and Google may read or set its own cookies, especially if you are signed in to Google. Google acts as an independent controller and applies its own privacy policy and cookie policy. Cookies that Google has set on its own domain are deleted from your browser settings. The "Directions" link opens Google Maps in a new tab.

Fonts are served from our own servers. The website does not connect to Google Fonts or to other external font services.

Links to LinkedIn, EUR-Lex or the AEAT Electronic Office take you to third-party sites that we do not control. Each of them will inform you about its cookies.

6. How to change or withdraw your decision

The first time you open any page of the website, we ask you with a cookie notice that does not stop you browsing. At the foot of every page you will find the Cookie preferences link, which opens the panel to change your choice whenever you want. If you withdraw consent for Google Maps, the map stops loading. If we ever enable audience measurement and you withdraw your consent, we will stop measuring immediately and delete Google Analytics cookies from your browser. If your browser sends the Global Privacy Control signal, we treat it as a rejection and do not show you the notice. You can change this from the same link.

Rejecting is as easy as accepting and has no consequences: the website works the same way and you will see exactly the same content. We will ask you again after twelve months, or sooner if we change anything relevant in this policy.

You can also view, block or delete cookies from your browser settings. If you block necessary cookies, some security checks may be repeated or the Guiex tariff classification agent may not work.

• Google Chrome
• Mozilla Firefox
• Safari
• Microsoft Edge

7. Updates to this policy

If in the future we add cookies for a purpose other than those described here, we will update this policy and ask you again before setting them. The version in force is the one published on this page, with its update date. This policy is published in Spanish, Catalan and English. In the event of any discrepancy, the Spanish version prevails.

For any question about cookies, write to us at info@guiex.net.

1. You are interacting with an artificial intelligence

In accordance with Article 50(1) of Regulation (EU) 2024/1689 (AI Act), we tell you clearly before you start:

"You are interacting with a GUIEX artificial intelligence system. Responses are generated automatically from your description, from the documents you attach, from the European Union TARIC tariff, from public BTI decisions of the European Commission and, in Reasoned mode, from Google searches. No person reviews each result."

An equivalent notice is displayed next to the agent’s own form before the first interaction, and every page of the PDF report states that it is content generated with artificial intelligence assistance.

2. The result is indicative and non-binding

The result of the Guiex tariff classification agent is an indicative tariff classification proposal. Please bear in mind the following:

• It is not Binding Tariff Information (BTI).
• It is not customs, tax or legal advice from Guiex.
• It is not a decision of the authorities and creates no rights against the AEAT or against Guiex.
• The final classification must be validated by a professional before it is declared to Customs. Artificial intelligence models can make mistakes, even when the answer seems confident.

For a classification to bind Customs in respect of your goods you need a Binding Tariff Information (BTI) decision. The AEAT issues it at the applicant’s request under Article 33 of Regulation (EU) No 952/2013 (Union Customs Code), it covers goods that correspond in all respects to those described and it is valid for three years. Guiex, as a customs representative, can apply for it on your behalf under contract.

Guiex is not liable for the consequences of using the result without professional validation, including duty assessments, penalties or delays arising from an incorrect classification. This limitation applies to the fullest extent permitted by law and does not cover cases of wilful misconduct or gross negligence.

3. How she works

The Guiex tariff classification agent is free and requires no registration. You write a description of the goods and, if you wish, attach documents such as invoices, technical data sheets or photographs. From there:

1. When you start using the form, Cloudflare Turnstile checks that it is not being used by an automated program.
2. Our backend, hosted on Google Cloud Run (europe-west1 region, Belgium), receives the query.
3. The Google Gemini artificial intelligence model, through Vertex AI in the European Union’s eu multi-region, analyses the description and the documents and proposes a classification. In Reasoned mode it may search Google to identify the product. Fast mode does not search the web.
4. The system that coordinates the agent’s tools and checks consults the European Union’s TARIC to verify the code and applicable measures. These queries only include codes and countries, never your personal data or documents.
5. Public BTI decisions from the European Commission’s database are cross-checked.
6. A PDF report is generated for you to download on the spot. We do not send it to you by email.

4. What data is used and what happens to it: temporary processing

The query, documents and report are processed temporarily to generate the result and to let you reconnect and download it. No permanent history is kept. Access to the query expires 60 minutes after completion. Physical deletion is not simultaneous: it happens at the next automatic cleanup, which runs when the service receives a new query, or when the server instance shuts down, since it keeps this data only in its temporary memory. We do not obtain sales leads from the agent. Save the report if you want to keep it.

Guiex does not use your data or your documents to train artificial intelligence models, and does not sell or pass them on to third parties for their own purposes. They are processed only, as processors and under contract, by the essential technology providers: Google Cloud EMEA Limited (processing in the European Union and, in Reasoned mode, searches on Google Search) and Cloudflare, Inc. (anti-bot checks). Google does not use Vertex AI data to train its models.

Technical records also remain. Infrastructure security logs, including the IP address, are kept for no more than 30 days. The per-IP request counter lasts up to 24 hours. Google keeps the web searches made in Reasoned mode for up to 3 days. Full details are in the Privacy policy.

5. What you should not attach

To classify goods we only need to know what they are, what they are made of and what they are for. Therefore:

• Attach only what is needed. You can redact prices, names, signatures and any personal data: we do not use them.
• Do not attach health data or other special categories of data (ethnic origin, political opinions, religion, trade union membership, biometric or genetic data, sex life).
• Do not attach classified information, information subject to professional secrecy or information you are not entitled to share.

By attaching a document you warrant that you are entitled to share it with Guiex for this purpose.

6. Usage limits

• The agent is intended for professionals and for people aged 18 or over.
• There are query quotas per IP address, per hour and per day. If you exceed them, you will have to wait up to an hour or, if you use up the daily quota, until the next day.
• Each query accepts a maximum of 20 products and 5 attached documents, up to 10 MB each and 20 MB in total, with a limit of 30 pages per PDF.
• Automated use through bots, scripts or integrations is prohibited, as is circumventing the verification systems or the limits.

Guiex may change the limits, temporarily suspend the service or withdraw it at any time, without this giving rise to any right to compensation.

7. Content generated by artificial intelligence

The PDF report is content generated by artificial intelligence. In accordance with Article 50(2) of Regulation (EU) 2024/1689, it visibly carries, on every page, the legend "Generated with artificial intelligence assistance · indicative and not binding" and metadata identifying it as artificially generated content. Do not remove that legend if you share the report.

8. What you can do with the report

You may use the report for your own purposes: preparing a declaration, checking it with your customs representative or documenting an internal analysis. You may not present it as an opinion, a certification or advice from Guiex, or remove the references to its indicative nature. The TARIC nomenclature and the BTI decisions it cites are public information from the European Commission.

9. If you need a classification with guarantees

If you are going to import or export regularly, or if the classification has a significant impact on customs duties, licences or trade policy measures, you would be well advised to obtain a professional classification or Binding Tariff Information. Guiex, as a customs representative registered with the AEAT, can:

• Prepare a signed, reasoned tariff classification opinion.
• Apply on your behalf for a BTI from the AEAT, which binds the customs authorities throughout the European Union in respect of you as holder for three years.

Write to us at info@guiex.net or call us on +34 93 488 50 34. You can also use the contact page.

10. Changes, languages and applicable law

We may update these terms when the service, the providers or the regulations change. The version in force is the one published on this page, with its update date. These terms are published in Spanish, Catalan and English. In the event of any discrepancy, the Spanish version prevails. They are governed by Spanish law and are supplemented by the Legal notice and terms of use.
