Q: Are 6-digit commodity codes included in 4-digit commodity codes or are they separate? For example, is the code 220890 included in the 2208 or not?
A: Each six-digit HS code is identified by its HS Chapter (first two digits) and HS heading (first four digits). In UN Comtrade, data is processed at the six-digit HS level and then aggregated to the four-digit and two-digit levels. For example, the commodity code HS 220890 (along with other six-digit codes under the HS 2208 heading) is aggregated into HS heading 2208 and included in HS Chapter 22.
