2936.29

Analysis

Subheading 2936.29 covers other vitamins and their derivatives, within heading 2936. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 4 US tariff lines below it are national.

Every one of its 4 tariff lines is duty-free at the general rate, so classification within the subheading affects statistics and Chapter 99 measures rather than the base duty.

The US splits it as follows: 2936.29.10 for other vitamins and their derivatives: folic acid (duty-free), 2936.29.16 for niacin and niacinamide (duty-free), 2936.29.20 for aromatic or modified aromatic (duty-free) and 2936.29.50 for other: other (duty-free).

By Census's concordance, most of its statistical lines are made by Medicinal and Botanical Manufacturing (325411) and Pharmaceutical Preparation Manufacturing (325412). Those are the NAICS industries a US producer of these goods would report under.

Goods only reach 2936.29 once they fall within heading 2936 (provitamins and vitamins, natural or reproduced by synthesis (including natural…). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
