U.S. imports of vegetable alkaloids and their derivatives (other) (HS 293979) totaled $21.9M in April 2026, traded with 16 countries.
Last updated: April 2026 dataSwitzerland leads US imports of other vegetable alkaloids under tariff line 2939790000, a broad residual category that captures plant-derived alkaloids — such as colchicine, pilocarpine, and strychnine — not classified elsewhere in Chapter 29. China and India are also significant sources. The regulatory treatment at entry varies sharply by compound: some are FDA-regulated APIs requiring cGMP documentation, others are DEA-controlled substances requiring import permits, and a few are subject to both regimes simultaneously. Importers should confirm the specific compound's regulatory status before shipment rather than relying on the heading's general classification.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The importer should check the DEA's published schedules of controlled substances and List I/II chemicals for the specific compound by CAS number. If the substance is scheduled, a DEA registration and import permit are mandatory regardless of its HTS classification. A licensed customs broker with pharmaceutical experience can help map the chemical identity to the correct regulatory pathway.
This subheading is a residual 'not elsewhere specified' category for vegetable-origin alkaloids. Compounds with their own dedicated subheadings — such as caffeine, ephedrine, or ergot alkaloids — must be classified there instead. If a compound is synthetic but structurally identical to a plant alkaloid, classification may depend on whether it is 'reproduced by synthesis,' which can shift it to heading 2939800050.
