Customs tariff number

What the customs tariff number is

The customs tariff number is a sequence of digits assigning every item to a class. It determines the duty rate, the applicable import rules and possible bans or licence requirements. Anyone moving goods across a customs border needs it, and anyone stating it wrongly is liable for that.

The number is hierarchical. The first digits denote the product group, the following ones subgroups, and the last digits narrow down the specific item. That is why it is long, and why the precision of the description decides the outcome. An item that could fit two numbers is classified by its actual nature and not by the name in the shop.

Who decides the classification

Responsibility lies with the declarant, meaning the importer or exporter, not with the carrier and not with the supplier. A carrier can help with the declaration but does not carry the risk of classification. That is why a supplier's statement about their own number is no evidence for yours.

For doubtful cases there is the binding tariff information. It is an official decision on the classification of a specific article, applies for several years and protects against a later change. For recurring imports that is the clean route.

Why a wrong number becomes expensive

• Retroactive payment: if duty was paid too low, customs claims the difference with interest.
• Retrospection: the review covers several years, so the claim can amount to a multiple of a single shipment.
• Procedural breach: wrong statements can count as an infringement, which goes beyond the payment itself.
• Effect on costing: the duty rate shifts the calculation. An item at two percent and one at twelve percent are costed differently, and a wrong assumption distorts the margin.

What import and export require

Besides the number, every shipment needs a customs declaration, a commercial invoice with complete details, the statement of value and the statement of origin. Origin is not the place of dispatch. A parcel from Asia can contain goods of European origin, and the other way round. Exports from the EU can carry export restrictions and licence requirements, for instance with dual use goods usable for both civil and military purposes.

For a shop it additionally matters who carries the charges. On deliveries to private customers in third countries the recipient is the customs debtor, which the shop has to tell the customer before the purchase. If that note is missing, the invoice annoys the recipient, who refuses the delivery, and the shop carries the return cost.
