Analysis
HTS 2922.21.50 covers other: other under heading 2922 (oxygen-function amino-compounds).
Within this group the rate runs from duty-free to 6.5%. Compared with 2922.21.25 (1-Amino-8-hydroxy-4,6-naphthalenedisulfonic acid, monosodium salt), which pays duty-free, a misclassification either way moves the duty by 6.5 percentage points.
The general duty rate is 6.5% of the customs value, which is above most the rates in chapter 29 (83rd percentile of 1050 lines with an ad valorem rate). On a shipment valued at $10,000 that is $650 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 13 others can enter duty-free instead of paying 6.5%. 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 other lines in the same group are 2922.21.10 (1-Amino-8-hydroxy-3,6-naphthalenedisulfonic acid…, 5.8%), 2922.21.25 (1-Amino-8-hydroxy-4,6-naphthalenedisulfonic acid…, duty-free) and 2922.21.40 (products described in additional U.S. note 3 to section VI, 6.5%).
Census statistics map these goods to NAICS 325194 (Cyclic Crude, Intermediate, and Gum and Wood Chemical Manufacturing), an industry of 68 US establishments employing 5,542 people. That concordance is how imports of this line are compared with US output.
