Binding Tariff Information (BTI): The Complete Guide to Securing Your Customs Classification

A tariff classification error costs importing companies an average of €8,400 in reassessed duties and cumulative penalties. When penalties can reach 150% of evaded duties, the question is no longer whether you should secure your nomenclature, but how to do it effectively. Binding Tariff Information (BTI) is precisely the tool designed by European customs authorities to meet this need. Free, valid for three years and enforceable throughout the European Union, it remains underused by operators. Here is everything you need to know to take advantage of it.

What is Binding Tariff Information?

Definition and Legal Framework

BTI is an official decision issued by customs authorities that fixes the tariff classification of a given product. Concretely, it assigns to a product a combined nomenclature (CN) code at eight digits or a TARIC code at ten digits. This mechanism is governed by the Union Customs Code (UCC), in force since 1 May 2016. Article 33 establishes the fundamental principle: a BTI issued by the customs authority of one Member State binds all customs administrations of all 27 EU countries. A BTI obtained in France applies the same way in Germany, Italy or any other Member State.

The "binding" nature of BTI means it legally commits two parties: the holder (who must use it in clearance operations) and customs services throughout the Union (who must respect the assigned classification).

The Link Between BTI and Tariff Classification

Tariff classification is the backbone of every customs operation. It determines the applicable customs duty rate, trade policy measures (quotas, anti-dumping, embargo), regulatory formalities (health standards, import licences), and any tariff preferences linked to free trade agreements. Without BTI, classification rests on the operator's or declarant's own assessment. That assessment, even in good faith, can be challenged during a post-clearance control. BTI eliminates this uncertainty by providing an official, legally enforceable answer.

Why Request BTI for Your Customs Operations?

Legal Protection Against Controls

BTI provides legal protection: in the event of a customs control, the holder has an official document justifying the classification used. Customs services cannot challenge this classification while the BTI is valid, except in very specific cases (regulatory change or error in the information provided). For companies importing products whose classification is open to interpretation (composite products, multi-function articles, complex food preparations), BTI provides lasting peace of mind.

Anticipate Your Customs Duties and Taxes

Knowing a product's tariff code with certainty enables precise calculation of customs duties, import VAT and any additional taxes before the first operation. This visibility is essential for building a reliable cost price, negotiating with suppliers and setting commercial margins without unpleasant surprises.

How to Obtain Binding Tariff Information

Prerequisites: EORI Number and EBTI Access

Before filing a request, three conditions must be met: an EORI number, a certified account on douane.gouv.fr, and accreditation to the EBTI (European Binding Tariff Information) online service. Since October 2024, all BTI requests go through the European EBTI-STP portal, which replaced the old French procedure via Soprano-RTC.

Filing Steps on the EBTI Portal

The entire procedure is digital. The applicant creates a file in EBTI-STP with a detailed description of the goods (composition, materials, manufacturing process, intended use), along with technical documentation, photographs and, if applicable, samples. Important: do not send samples spontaneously — wait for the CSMR's BTI Pole to make an explicit request. The quality of the initial description is decisive: too vague a description risks an imprecise or unusable classification; too restrictive a description limits the BTI's applicability to minor variants of the same product.

Processing Timelines and Admissibility

The administration has 30 days to rule on admissibility, then up to 120 days for instruction. Well-documented files requiring no additional analysis are often processed faster.

Validity and Legal Scope of BTI

3-Year Validity Throughout the EU

Since the UCC came into force in 2016, BTI validity is set at three years (previously six). During this period, the holder must cite their BTI reference in every customs declaration for the goods concerned. Each BTI covers only one product — multiple BTI requests are needed for multiple distinct goods.

Cases of Cancellation or Early Modification

A BTI can cease to have effect before its expiry in several situations: cancellation if issued on the basis of inaccurate or incomplete information; revocation in case of regulatory change (new classification regulation, modified combined nomenclature, new explanatory notes); six-month extended use period in case of unfavourable revocation (duty increase), to be requested within 30 days of the revocation notification.

Common Errors to Avoid with BTI

• Relying on the supplier's classification: a customs code proposed by a seller has no legal value. The importer alone is responsible for the declared classification.
• Providing an incomplete description: omitting composition, manufacturing process or intended use risks an imprecise classification or refusal.
• Neglecting nomenclature notes: section and chapter headings are only indicative — classification rules lie in the legal notes, which can radically change interpretation.
• Not anticipating renewal: an expired BTI loses all binding force. Start the new request several months before expiry.
• Forgetting to cite BTI in the declaration: the holder is obligated to mention their BTI reference at clearance.

BTI and Global Customs Compliance

BTI is part of a broader customs compliance approach, alongside AEO status, customs audits and team training. The complexity of the tariff nomenclature (over 15,000 codes in the combined nomenclature) and the financial stakes linked to classification often justify using a registered customs representative. A RDE assists the company in preparing the request, drafting the technical description, and following up the procedure with the CSMR.

Frequently Asked Questions about BTI

How much does BTI cost?

The BTI request is completely free. No fee is charged by customs administration, either at application or at the issue of the decision. Any indirect costs are limited to preparation time or advisory fees if you choose professional support.

Is BTI mandatory?

No, BTI is a voluntary process. No regulation requires operators to hold one for import or export operations. However, without BTI, classification is subject to customs services' interpretation, with the reassessment risk that entails.

Can a BTI classification be challenged?

Yes. If the applicant believes the classification assigned by customs is incorrect, administrative and legal recourse is available. Administrative recourse must first be filed with the customs authority that issued the decision, then judicial recourse before the competent court if unsuccessful.

What is the difference between BTI and a non-binding tariff ruling?

A non-binding tariff ruling is an informal opinion indicating a probable classification but not legally binding. The BTI, by contrast, has the force of law throughout its validity period and binds all EU customs services.
