About Chapter 98
Chapter 98 contains 118 10-digit statistical lines grouped under 0 4-digit headings. Brokers, importers, and customs counsel use these codes to declare special classification provisions on entry summaries (CBP Form 7501) and to look up the applicable Column 1, Special, and Column 2 duty rates.
All 118 10-digit lines in this chapter enter duty-free under the general (Column 1) rate. Country-of-origin overlays (Section 301 for China, Section 232 for steel/aluminum, IEEPA reciprocal tariffs, AD/CVD orders) can still apply on top of the base rate — open any code for the live overlay stack.
Every code page links into the Tandom Tariff Calculator with the HTS code prefilled, so you can compute the full landed duty for a specific shipment by entering value, country of origin, and (where relevant) material content or date of entry. 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.
