Analysis
HTS 2811.19.61 covers other: other under heading 2811 (other inorganic acids and other inorganic oxygen compounds of nonmetals). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.
Rates on the nearby lines range from duty-free to 2.3%. The costliest confusion would be with 2811.19.30 (other: hydrobromic acid) at duty-free, a difference of 4.2 points on the customs value.
The general duty rate is 4.2% of the customs value, which is above most the rates in chapter 28 (82nd percentile of 274 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.
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 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.
For statistics it divides in two: 2811.19.61.10 for sulfamic acid and 2811.19.61.90 for other. Both pay the same duty; the suffix records which kind was imported.
The column 2 rate, for countries without normal trade relations, is 25%, 6.0 times the general rate.
