HTS tariff line · chapter 29
2909.30.09
Bis(tribromophenoxy)ethane; Pentabromodiphenyl oxide; and Tetra decabromodiphenoxy benzene
Analysis
HTS 2909.30.09 covers bis(tribromophenoxy)ethane; Pentabromodiphenyl oxide; and Tetra decabromodiphenoxy benzene under heading 2909 (ethers, ether-alcohols, ether-phenols, ether-alcohol- phenols, alcohol peroxides, ether…).
Neighbouring lines carry rates from 5.5% to 5.5%, so the exact line matters. The widest gap is with 2909.30.60 (other: other), at 5.5%: a product that belongs there but is entered here, or the reverse, changes the duty by 5.5 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.
