HS Codes API
The World Customs Organization Harmonized System (HS) as an API — 6,900+ commodity classification codes used for customs, tariffs and international trade. Look up any HS code (2-digit chapter, 4-digit heading or 6-digit subheading) with its description and full ancestor chain, search the nomenclature by product, or drill into the sub-codes of a code. Ideal for logistics, customs, e-commerce and trade-compliance tooling.
