A code answers a description
The Harmonized System is an international nomenclature of goods maintained by the World Customs Organization and used by customs administrations to describe goods in a common structure. In practice, an importer meets it as a numeric code on a declaration. The code looks like a fact about the product. It is closer to a conclusion about a description. If the description is incomplete, the conclusion is unreliable, however confident the number looks.
This is why classification questions begin with the product and not with the code. The more precisely you can say what the product is made of, what it does and how it is presented, the better the review.
What a reviewer will ask
| Question | Why it matters | Where the answer usually is |
|---|---|---|
| What is it made of? | Material often separates one heading from another | Specification sheet, bill of materials, supplier |
| What does it do? | Function can decide between headings for similar-looking goods | Datasheet, manual, brochure |
| How is it composed? | Mixtures, sets and assembled goods are read differently from simple goods | Composition statement, drawings |
| In what form is it presented? | Complete, incomplete, disassembled, retail packing or bulk | Packing list, photographs |
| What is it used for? | Intended use can matter where the nomenclature refers to it | Importer’s own use statement |
| What supporting evidence exists? | Test reports and certificates can settle a factual question | Laboratory, manufacturer |
A supplier’s code is a suggestion
Suppliers frequently write a code on the invoice. It may be correct. It may also reflect the supplier’s own country’s practice, an older edition of the nomenclature or a convenient approximation. The importer who makes the declaration carries the responsibility for what it says, so the useful stance is to treat the supplier’s code as a hypothesis and to mark it on your documents as suggested or as confirmed, depending on which it is.
Do not look for a way to arrive at a lower duty. Look for the description that is true and complete, and let the classification follow from it.
A product dossier, step by step
- Write a one-sentence description in plain words that a non-specialist would understand.
- Add a technical description: material, dimensions, composition by percentage where relevant, and how it works.
- Attach the supplier’s datasheet or specification, a clear photograph and, if the product is a set, a list of its parts.
- State the intended use and the state in which it will be imported.
- Record the code the supplier gave, where it came from, and mark it as suggested.
- Note any previous ruling, question or inspection involving the same or a similar product.
- Keep the dossier with the import file so that the same answer is used for the next shipment.
A document-consistency example
Hypothetical example, invented for illustration. No classification is suggested.
An importer describes an item on the invoice as "LED strip light, 5 m". The supplier’s datasheet describes it as a "decorative lighting set with power adapter and remote". The packing list lists the adapter and remote separately. Three descriptions now exist for what may be one article or three.
Before asking for any code, the importer asks the supplier whether the strip, adapter and remote are packed and sold together as a set, and for a single wording to use on every document. Only then is the question put to an adviser or the authority.
The purpose of the example is to show the preparation. The article does not say how the goods in it would be classified, and neither should a reader assume it.
Where to take the question
- To your customs broker, who handles declarations and can raise a question with the authority on your behalf.
- To the authority’s published guidance and its channels for classification enquiries, as described on the customs administration’s pages.
- To the manufacturer, for technical facts you cannot find yourself.
Mistakes that make a review slower
Three habits slow a classification review. The first is sending only a photograph, which shows shape but not material or function. The second is describing the product by its brand or model name alone, which tells the reviewer nothing about what it is. The third is sending different descriptions to different parties, so that the broker, the supplier and the authority each hold a different version. Fix one description, share it, and update every copy when it changes.
Keep the answer for next time
When a classification question is resolved, record the question, the date, the product dossier version, who answered and on what basis. The next shipment of the same product can then start from a written answer, and a change in the product, the supplier or the nomenclature edition is a reason to ask again, not to assume the old answer still holds. The record also protects the importer if the same goods are questioned later, because it shows the care taken at the time.
Store the dossier and the answer together in the import file, with the supplier’s datasheet attached, so that anyone who handles the next shipment finds both in the same place.
Limits of this guide
This is preparation guidance and not a classification ruling. Classification depends on the edition of the nomenclature in force, national tariff structure and the authority’s reading of the facts, none of which this article assigns. The DJBC guidance on import describes the declaration process that uses the code. Binding determinations come from the competent authority, not from an article.
