Analysis
HTS 2830.90.15 covers other: other zinc sulfide under heading 2830 (sulfides; polysulfides, whether or not chemically defined).
Neighbouring lines carry rates from duty-free to 3.1%, so the exact line matters. The widest gap is with 2830.90.10 (zinc sulfide, luminescent grade having a purity of 99.99 percent or…), at duty-free: a product that belongs there but is entered here, or the reverse, changes the duty by 2.8 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 2.8%. 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 general duty rate is 2.8% of the customs value, which is in the middle of the rates in chapter 28 (44th percentile of 274 lines with an ad valorem rate). On a shipment valued at $10,000 that is $280 in duty before any Chapter 99 additions or preference claims.
The other lines in the same group are 2830.90.10 (zinc sulfide, luminescent grade having a purity of 99.99…, duty-free), 2830.90.20 (other: cadmium sulfide, 3.1%) and 2830.90.90 (other: other, 3%).
