When the invoice is not enough to classify

The tariff classifies goods by the terms of its headings and notes [1], and German customs notes that many goods can be classified only when both what they are made of and what they are used for are taken into account [7]. An invoice line is written to sell the goods, so it often leaves exactly that out. Take "ceramic dinner plate, 27 cm". In the 2026 Combined Nomenclature, ceramic tableware of porcelain or china is 6911 10 00, with a conventional duty of 12%, while ceramic tableware other than of porcelain or china falls under 6912 00, at 5% to 9% depending on the ceramic [1]. The invoice does not say which ceramic it is. The supplier knows.

One plate, five possible codes

These are the 2026 codes for ceramic tableware and kitchenware [1]:

The chapter itself has a condition too: Chapter 69 applies only to ceramic products which have been fired after shaping [1]. And if the plate is not tableware at all but a decorative wall plate, it may belong in heading 6913, statuettes and other ornamental ceramic articles, where porcelain is 6% [1]. Material, use and presentation each move the code, and the invoice line settles none of them.

What the tariff asks that invoices skip

The General Rules for the Interpretation of the Combined Nomenclature make the terms of the headings and the section and chapter notes decisive [1]. The rules then deal with the cases an invoice blurs: a reference to a material covers goods made wholly or partly of it, goods of more than one material are classified by rule 3, and goods put up in sets for retail sale that rule 3(a) cannot classify are classified by the material or component that gives them their essential character, in so far as that criterion applies [1].

The declaration asks for the same precision. For a declaration for release for free circulation, the description of goods is "the normal trade description", in "terms sufficiently precise to enable immediate and unambiguous identification and classification of the goods" [2]. German customs asks declarants to supplement a description that falls short with the kind of material, the kind of processing and the intended use [3].

The origin matters as well: TARIC holds the measures attached to the tariff, from tariff preferences to anti-dumping and countervailing duties [4]. The declaration asks for the country of origin, unless a preference is claimed and the preferential origin is the same country, in which case the country of preferential origin is given [2].

Questions only the supplier can answer

A good question names the line, asks one thing, and can be answered from the product specification. For the plate:

1. Material. Is the plate porcelain or china, or another ceramic? If another, is it common pottery, stoneware, or earthenware or fine pottery?
2. Use. Is it made to serve food, or to be displayed as decoration?
3. Presentation. Is it sold on its own, or as part of a set for retail sale, and if so, what else is in the set?
4. Origin. In which country was it made, and, if a preferential rate is to be claimed, can the supplier provide the proof of origin?

The same shape works for other goods. A garment needs its fibre composition, a machine part its function in the machine, a chemical its composition and CAS number, which German customs recommends giving for chemicals [3].

Some questions belong to the buyer, not the supplier. Whether buyer and seller are related, and whether royalties are paid as a condition of sale, are questions about the value of the goods [5].

Keep the answer with the case

The person who lodges a declaration is responsible for the accuracy and completeness of its information and for the documents supporting it, and so is a customs representative who lodges it [5]. Supporting documents have to be in the declarant's possession when the declaration is lodged [5]. A supplier's written answer on the material is the kind of evidence worth keeping next to the invoice line it explains.

When the answer is still not enough

Some goods stay uncertain after the supplier has answered. Before asking for a binding decision, anyone can contact the customs authority for general, non-binding information on the classification of goods; only a Binding Tariff Information decision is binding [6]. How to use existing decisions, and when to apply for one, is in the guide on binding tariff information.
