Butyl (R)-2-[4-(5-trifluoromethyl-2- pyridinyloxy)phenoxy]propanoate
Analysis
HTS 2933.99.01 covers butyl (R)-2-[4-(5-trifluoromethyl-2- pyridinyloxy)phenoxy]propanoate under heading 2933 (heterocyclic compounds with nitrogen hetero-atom(s) only).
Neighbouring lines carry rates from duty-free to 6.5%, so the exact line matters. The widest gap is with 2933.99.97 (other: other), at 6.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 6.5 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 26% of the 1050 tariff lines in chapter 29. 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 is the industry code a US manufacturer of the same product would normally use.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
