2-[4-[(6-Chloro-2-quinoxalinyl)oxy]phenoxy]- propionic acid, ethyl ester
Analysis
HTS 2933.99.02 covers 2-[4-[(6-Chloro-2-quinoxalinyl)oxy]phenoxy]- propionic acid, ethyl ester under heading 2933 (heterocyclic compounds with nitrogen hetero-atom(s) only).
Within this group the rate runs from duty-free to 6.5%. Compared with 2933.99.97 (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.
Census statistics map these goods to NAICS 325199 (All Other Basic Organic Chemical Manufacturing), an industry of 894 US establishments employing 77,304 people. That concordance is how imports of this line are compared with US output.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
