Before Asking for an HS Code: Prepare a Product Dossier That Can Be Verified

Start with the actual goods

The World Customs Organization describes the HS as an international goods nomenclature system, with headings identified by six-digit codes and classification rules. The system is used as a basis for customs tariffs and trade statistics. This introductory material helps explain the role of the HS; it does not provide a classification conclusion for a specific product.

The guide below presents an information-preparation approach recommended by the editorial team, suitable for businesses purchasing machinery, components, or products with multiple variations. This is not a notice of tariff code changes in October 2026.

One product code, one information set

Assign an internal code to each product and attach that same code to the images, catalogue, and quotation line. For equipment sets with accessories, clearly state which components are supplied together and which are purchased separately. If the supplier uses the same sales name for multiple configurations, ask them to mark the exact selected configuration on the documents.

Checklist to send to the person responsible for classification

1. Describe what the product does and the circumstances in which it is used. For components, state where they are installed, their separate function, and whether they are sold independently. Do not simply write “machine accessory” if a more specific name and specifications are available.

2. Provide the construction, materials, or composition confirmed by the supplier. For equipment, add the operating principle and specifications for the exact model. Do not infer composition from color, trade names, or advertising images.

3. Add overall product images, label images, packaging images, and the catalogue. State whether the goods are new or used, and whether they are supplied as complete units or disassembled. If any information is unavailable, mark it as pending and identify the responsible contact person.

Handling cases where the two parties provide different codes

Ask each party to specify exactly which product they are describing and what data they rely on. For example, if one document states that the material is plastic while another states metal, that discrepancy should be resolved first. A code suggested by the seller is an input for review; it should not be copied into the dossier merely because a similar shipment was previously delivered.

Keep the data set used at the time of discussion. When the supplier changes the construction, use, or composition, send the updated version to the responsible person for review; do not merely rename the file.

Expected outcome and the article's limitations

Conclude the preparation step with a list of data that is complete, questions that remain unanswered, and the next person responsible for handling them. The declared code, tax rate, and specialized management requirements must be checked against the goods and applicable regulations. This article does not assign an HS code or confirm that an item may be imported based solely on an image or name.
