2921.45.25
Mixtures of 5- and 8-amino-2-naphthalene- sulfonic acid; 2-Naphthylamine-6-sulfonic acid; ando-Naphthionic acid (1-amino- 2-naphthalene- sulfonic acid)
Analysis
HTS 2921.45.25 covers mixtures of 5- and 8-amino-2-naphthalene- sulfonic acid; 2-Naphthylamine-6-sulfonic acid; ando-Naphthionic acid (1-amino- 2-naphthalene- sulfonic acid) under heading 2921 (amine-function compounds).
Within this group the rate runs from 5.8% to 6.5%. Compared with 2921.45.90 (other: other), which pays 6.5%, a misclassification either way moves the duty by 6.5 percentage points.
The normal trade relations rate here is zero, shared by about 26% of the 1050 tariff lines in chapter 29, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
The other lines in the same group are 2921.45.10 (7-Amino-1,3-naphthalenedisulfonic acid and its salts…, 6.5%), 2921.45.20 (3-Amino-2,7-naphthalenedisulfonic acid…, 5.8%), 2921.45.60 (products described in additional U.S. note 3 to section VI, 6.5%) and 2921.45.90 (other: other, 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.
