Analysis
HTS 2833.11.50 covers disodium sulfate: other under heading 2833 (sulfates; alums; peroxosulfates (persulfates)). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in metric tons.
Within this group the rate runs from duty-free to 5.5%. Compared with 2833.29.30 (other: of vanadium), which pays 5.5%, a misclassification either way moves the duty by 5.1 percentage points.
The general duty rate is 0.4% of the customs value, which is in the middle of the rates in chapter 28 (31st percentile of 274 lines with an ad valorem rate). On a shipment valued at $10,000 that is $40 in duty before any Chapter 99 additions or preference claims.
For statistics it divides in two: 2833.11.50.10 for anhydrous and 2833.11.50.50 for other. Both pay the same duty; the suffix records which kind was imported.
Census statistics map these goods to NAICS 325180 (Other Basic Inorganic Chemical Manufacturing), an industry of 705 US establishments employing 41,447 people. That concordance is how imports of this line are compared with US output.
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 0.4%. 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.
