Analysis
HTS 2930.90.49 covers acids: other under heading 2930 (organo-sulfur compounds). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in kilograms.
Within this group the rate runs from duty-free to 6.5%. Compared with 2930.90.71 (other: dibutylthiourea), which pays duty-free, a misclassification either way moves the duty by 4.2 percentage points.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 13 others can enter duty-free instead of paying 4.2%. 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 4.2% of the customs value, which is in the middle of the rates in chapter 29 (42nd percentile of 1050 lines with an ad valorem rate). On a shipment valued at $10,000 that is $420 in duty before any Chapter 99 additions or preference claims.
The column 2 rate, for countries without normal trade relations, is 25%, 6.0 times the general rate.
