About Chapter 50
Chapter 50 contains 30 10-digit statistical lines grouped under 1 4-digit headings. Brokers, importers, and customs counsel use these codes to declare silk on entry summaries (CBP Form 7501) and to look up the published Column 1, Special, and Column 2 rate notation.
General (Column 1) duty rates for ad-valorem lines in Chapter 50 range from 0.8% to 3.9%, with a median of 3.9%. About 43% of the chapter's lines (13 of 30) enter duty-free under the general rate. Special-rate notation (including USMCA, KORUS, AGOA, and GSP when authorized) and Chapter 99 measures can modify these base rates for qualifying shipments.
Product-code pages link into the Tandom Tariff Calculator with the base HTS code prefilled. Chapter 99 provision pages instead show mapped base codes and send you to a dated calculator scenario, which determines whether a measure applies from the entry facts. Tandom's data refreshes daily from USITC HTSUS, CBP CSMS, the Federal Register, and the Department of Commerce — the same authoritative sources the trade community files against.
