Last updated: April 2026 dataCholine chloride — the commercially dominant salt form — is widely used as a feed supplement in poultry and swine nutrition and as a precursor in pharmaceutical and cosmetic formulations. Classified under a single 10-digit line (2923100000), this heading has a straightforward structure but significant trade volume driven by animal feed demand. China is the leading supplier by a wide margin, with Italy and Belgium also notable sources. Importers sourcing food- or feed-grade choline should ensure compliance with FDA and AAFCO labeling standards, as grade specifications directly affect admissibility for use in animal feed.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Feed-grade choline chloride must meet purity and labeling standards set by FDA and recognized by AAFCO for use in animal nutrition. Industrial-grade material may not meet these specifications. Importers should obtain a certificate of analysis from the supplier confirming the grade and ensure the product label accurately reflects its intended use, as misrepresenting feed-grade status can trigger FDA enforcement action.
Importers should verify current Section 301 tariff list status for choline and its salts originating from China, as chemical products in HTS Chapter 29 have been broadly affected by Section 301 actions. The applicable additional duty, if any, is determined by the specific 10-digit line and the current list status at the time of entry.
