The schedule separates drug-use lines (2921493800 for antidepressants and tranquilizers; 2921494300 for other aromatic monoamine drugs) from general industrial and dye-intermediate compounds. Correct classification depends on the compound's identity and its intended use, so importers should confirm the end-use designation with a licensed customs broker before entry.
Imports originating from China may be subject to Section 301 tariffs depending on the specific 10-digit line. The applicability varies by compound and tariff line, so verifying current Section 301 list coverage for the precise HTS code is essential before shipment.
