3825.61.00

Analysis

HTS 3825.61.00 covers mainly containing organic constituents under heading 3825 (residual products of the chemical or allied industries, not elsewhere specified or…).

The normal trade relations rate here is zero, shared by about 25% of the 179 tariff lines in chapter 38, 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.

All 8 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.

The general rate of Free has not changed in any edition of the schedule since Jan 2023.
