HTS 2936.25.00 covers vitamin B6 (Pyridoxine and related compounds with Vitamin B6 activity) and its derivatives under heading 2936 (provitamins and vitamins, natural or reproduced by synthesis (including natural…).

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.

Goods from countries without normal trade relations pay the column 2 rate of 25% instead of nothing, so origin decides between free entry and a 25% duty.

Census statistics map these goods to NAICS 325411 (Medicinal and Botanical Manufacturing), an industry of 761 US establishments employing 30,382 people. That concordance is how imports of this line are compared with US output.

All 12 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.
