Motivation

Codes within the Harmonized System are used globally to classify goods, products and objects for customs purposes when they are traded internationally between country borders. The Harmonized System is a taxonomy where each level in the taxonomoy is assigned a code. The World Customs Organization maintains this system on behalf of the 200+ member countries, so the applicability of these codes is very global and widely adopted.

Discussion

Comment Since it is described as a "category" or to "classify" things, can you describe whether you expect it to satisfy the uniqueness constraint we expect of identifiers (there should never be two items with the same value)? ArthurPSmith (talk) 17:56, 28 June 2018 (UTC)[reply]
Comment @ArthurPSmith: I forgot that rule about external-id! I've changed the data type to string instead as this is more appropriate. Dhx1 (talk) 01:06, 30 June 2018 (UTC)[reply]
