# The question is not whether you hold a BTI: it is whether the goods still correspond to it

A typical scenario, not our own case. A [manufacturing](https://csidia.com/en/sectors/manufacturing) company imports components from outside the EU and fits them into machinery it exports. Three years ago it obtained a BTI decision — binding tariff information — on the classification of one of the more delicate components. It has used it on every shipment since. Then a check arrives. The office does not ask whether the company holds the BTI: it asks whether, today, «the goods declared correspond in every respect to those described in the decision». And if the same company also holds a BOI decision — binding origin information — the twin question is whether «the goods in question and the circumstances determining the acquisition of origin correspond in every respect» to what the decision described. Not a document to produce: a correspondence to prove, today, on the actual product.

## The duty sits in Article 15; the proof sits in Article 33

Regulation (EU) No 952/2013, the Union Customs Code, places the general duty in Article 15(1): «Any person directly or indirectly involved in the accomplishment of customs formalities or in customs controls shall, at the request of the customs authorities and within any time-limit specified, provide those authorities with all the requisite documents and information, in an appropriate form, and all the assistance necessary for the completion of those formalities or controls». Not *whenever you have them ready*: within any time-limit specified. Paragraph 2 adds that lodging a customs declaration or an application for an authorisation renders the person concerned responsible for «the accuracy and completeness of the information» declared and for «the authenticity, accuracy and validity of any document supporting» it. The same distinction holds as for NIS supervision: [a signed policy is not enough; what is needed is the data proving it was implemented](https://csidia.com/en/notes/ispezione-nis-dati-che-dimostrano-attuazione).

Article 33 tightens the specific case. Paragraph 3 fixes the duration: «BTI or BOI decisions shall be valid for a period of three years from the date on which the decision takes effect». Paragraph 4 fixes the burden, and it is the sentence that makes the piece: to apply it, the holder «shall be able to prove that», in the case of a BTI decision, «the goods declared correspond in every respect to those described in the decision» — or, for origin, that «the goods in question and the circumstances determining the acquisition of origin correspond in every respect to the goods and the circumstances described in the decision». Three years of validity does not mean three years of peace of mind: it means three years in which, on every shipment, the correspondence has to hold up again.

## Where the data that matters actually sits

Correspondence *in every respect* is not a fact that lives in one place. For the component covered by the BTI, the bill of materials sits in the production management system. Suppliers' declarations of origin — establishing its preferential origin — sit in email folders or in a purchasing-office archive, often connected to nothing else: the same gap as [a supplier register that never says what a supplier actually does](https://csidia.com/en/notes/descrizione-che-non-nomina-registro-fornitori). The invoices proving the value and provenance of the purchase sit in accounting. The technical datasheets and product revisions — which say whether the component fitted today is still the one described three years ago — sit with the technical office, often in a PLM kept apart from the ERP. Transport documents and proof of shipment sit with [logistics](https://csidia.com/en/sectors/logistics) or with the freight forwarder. The customs declarations, finally, are held by the customs representative, not by the company itself.

Six systems, six departments, none of which holds on its own the answer Article 33 demands. And preferential origin — Article 64 sets this out plainly — does not follow a single rule: it changes depending on whether the goods benefit from an EU agreement with a non-member country, a unilateral EU measure, or a specific arrangement such as Ceuta and Melilla. Knowing which rule applies is itself a fact to track down.

## The risk is not a missing document

What makes this serious is not that a document goes missing. It is that the correspondence can stop holding without anyone noticing. A supplier changes, a bill-of-materials revision is issued, or the share of a material that determined origin shifts — and whoever makes that change is not who applied for the BTI three years earlier, nor knows it touches a decision still in use. The two facts live in different systems, updated by different people. We are not claiming this happens in specific cases: it is the structural risk built into Article 33, whenever a decision photographs a good on one date and the company keeps declaring it for three years.

## The penalty, and how long the file must be kept

Article 42(1) leaves penalties to the Member States, with one shared constraint: «Such penalties shall be effective, proportionate and dissuasive». We report no Italian amounts: none verified against a primary source. We do know how long the company must keep the proof ready: Article 51(1) requires the documents and information of Article 15(1) to be kept «for at least three years» from the end of the year the declaration was accepted — and paragraph 2 adds three further years where a check shows the entry must be corrected and the company has been notified, while an appeal or court proceedings extend it until the procedure ends. The same lesson as for trade secrets under the Data Act: [protection is built by mapping in advance, not once a request lands](https://csidia.com/en/notes/data-act-segreto-commerciale-tre-passaggi). On a BTI used across three years of shipments, the last file still needed can outlast the decision itself.

If customs asked tomorrow morning to prove correspondence for your best-selling product, how many systems would you need to open — ERP, PLM, accounting, logistics, freight forwarder — and how long would it take to put together an answer before «any time-limit specified» runs out?

## Where we stop

We do not provide customs advice, and we do not qualify the classification or origin of any goods: those are assessments for the operator and its customs representative. We worked from Regulation (EU) No 952/2013 (OJ L 269, 10.10.2013) and from the consolidated version on EUR-Lex dated 12 December 2022 — a «simple documentation tool» with no legal value of its own, which nonetheless confirms Articles 15, 33, 42 and 51 remain untouched since 2013. On the ADM website we verified the page on BTIs: applications go through the EU's General Trader Portal with an EORI number and national portal credentials; samples go to the Tariff and Classification Office in Rome; decisions issue within 120 days of acceptance, extendable by 30. We report no Italian penalty amounts: none verified against a primary source.
