The UN/ECE Recommendation 21 package-type codes — the codes used to describe the kind of packaging in trade, transport and customs documents (packing lists, dangerous-goods declarations, EDI messages) — as an API. The reference a logistics, customs or e-invoicing system needs. Each of 400+ codes (for example 1A = steel drum, 5H = woven-plastic bag, BX = box, CT = carton, JY = jerrican) carries an alphanumeric code, a name, a description and a numeric code. Look a code up, reverse-look-up the codes that share a numeric code, search by name, or list them all. This is the packaging-type CODE register — distinct from containercodes-api (ISO 6346 shipping containers) and unitcodes-api (units of measure). Served from memory — always fast.

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.
