Clients often say “we’ve used the same harmonized codes for years” and “our products are duty free“. As a Licensed Customs Broker and consultant this tells me that I need to do some checking on the client’s behalf. Using obsolete or invalid HTS (Harmonized Tariff Schedule) codes is a sign of an amateurish operation. It is likely that, for these clients, commercial invoice descriptions need updating. If they are also an exporter we should check ECCNs, License Exceptions, and Schedule B numbers as well.
The tariff archives show that the 2021 HTS was revised 12 times. The 2022 version already lists 6 revisions. Here are the links to the changes: https://hts.usitc.gov/view/list
Don’t assume that your codes are valid. A little due diligence helps avoid problems down the road. Contact email@example.com for a review of your HTS codes.
