Analysis
HTS 2830.90.90 covers other: other under heading 2830 (sulfides; polysulfides, whether or not chemically defined).
Within this group the rate runs from duty-free to 3.1%. Compared with 2830.90.10 (zinc sulfide, luminescent grade having a purity of 99.99 percent or…), which pays duty-free, a misclassification either way moves 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 general duty rate is 3% of the customs value, which is in the middle of the rates in chapter 28 (46th percentile of 274 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.
The column 2 rate, for countries without normal trade relations, is 25%, 8.3 times the general rate.
