What is HS Code?
An HS code is a product classification code under the Harmonized Commodity Description and Coding System, the international nomenclature maintained by the World Customs Organization under the HS Convention. The HS uses six-digit codes organised in sections, chapters (the first two digits), headings (four digits) and subheadings (six digits), covering more than 5,000 commodity groups. Classification follows the General Interpretative Rules, supported by the WCO Explanatory Notes and classification opinions. Countries extend the code nationally: the EU Combined Nomenclature uses eight digits and TARIC ten, while the US HTSUS uses ten digits. The HS is updated every five to six years; HS 2022, the seventh edition, entered into force on 1 January 2022 with 351 sets of amendments, and HS 2028, with 299 sets of amendments, takes effect on 1 January 2028.
Why it matters for forwarders
The HS code decides the duty rate, preferential origin rules, import and export controls, licensing and statistics for a shipment, so errors are expensive. The importer or exporter is legally responsible for the classification, even when the forwarder or broker enters it, and authorities can reassess duties and penalties for years after import. Commercial invoices often carry the seller's export code, which may not match the destination's national tariff line at eight or ten digits. Where a classification is uncertain, binding rulings such as EU BTI decisions or CBP rulings give legal certainty. Prepare for HS 2028 by reviewing product master data, because codes that change on 1 January 2028 will break duty calculations and licence references.
