Analysis
HTS 2518.20.00 covers calcined or sintered dolomite under heading 2518 (dolomite, whether or not calcined or sintered, including dolomite roughly trimmed or…).
The general duty rate is 3% of the customs value, which is among the highest the rates in chapter 25 (97th percentile of 78 lines with an ad valorem rate). On a shipment valued at $10,000 that is $300 in duty before any Chapter 99 additions or preference claims.
Neighbouring lines carry rates from duty-free to duty-free, so the exact line matters. The widest gap is with 2518.10.00 (dolomite, not calcined or sintered), at duty-free: a product that belongs there but is entered here, or the reverse, changes the duty by 3 percentage points.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 3%. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
The column 2 rate, for countries without normal trade relations, is 30%, 10.0 times the general rate.
