Last updated: August 2026 dataSodium citrate (2918151000) is the commercially dominant product in this heading, used extensively as a buffering agent and emulsifier in processed foods, beverages, and pharmaceutical formulations. Israel and India are the leading US import sources, with Germany, China, and Austria also supplying the market. The heading's two 10-digit lines separate sodium citrate from all other citrate salts and esters (2918155000), a distinction relevant when a single shipment contains multiple citrate compounds. Importers of food- and pharmaceutical-grade citrate salts should be prepared for FDA entry review, and those sourcing from China should verify whether antidumping orders covering citrate salts extend to their specific product.

The scope of US antidumping orders on citric acid from China has at various times included certain citrate salts. Importers should review the current scope language of the relevant Commerce Department order and, if uncertain whether their specific citrate compound is covered, request a scope ruling before importation to avoid unexpected duty liability.
The US schedule provides a dedicated line (2918151000) for sodium citrate specifically, while all other salts and esters of citric acid — including potassium citrate, calcium citrate, and triethyl citrate — fall under 2918155000. Importers shipping mixed citrate products in a single entry should ensure each component is correctly identified and classified on the entry summary.
