Tricalcium citrate (calcium citrate; INS 333) is a globally traded food additive and nutrient supplement used primarily as an acidity regulator/buffer, firming agent, and sequestrant, and also as a calcium source in fortified foods and supplements. Food-additive evaluations and specifications are anchored in FAO/WHO JECFA, including an ADI of "not specified" (not limited) for calcium citrate in the JECFA database and detailed purity/identity requirements in the FAO additive monograph. In international trade statistics, product-level identification is commonly proxied using HS 291815 (salts and esters of citric acid), which aggregates multiple citrate salts and esters rather than isolating tricalcium citrate alone. Using that HS proxy, 2024 trade flows show export supply concentrated in a small set of industrial chemical producers/exporters (notably China and Germany), with the United States and major EU member states among leading import markets.

Risks
Food Safety And Contaminants HighTricalcium citrate is traded as a food additive (INS 333) with tight identity and purity expectations (e.g., assay and impurity limits referenced in FAO/WHO JECFA specifications and FCC-linked regulatory frameworks). Non-compliance (heavy metals/other impurities outside specification, mislabeling between hydrate forms, or inadequate quality documentation) can trigger border rejections, recalls, or forced relabeling and disrupt downstream food and supplement production.Specify JECFA/FCC-aligned quality requirements in contracts, require lot-level CoA and traceability to recognized specifications, and implement incoming testing for key impurities aligned to target-market requirements.
Regulatory Compliance MediumPermissions, functional-use expectations, and labeling conventions vary by jurisdiction even when an additive is recognized internationally (e.g., INS 333 in Codex/JECFA contexts versus national regulatory listings). Changes in additive provisions, contaminant limits, or infant-formula-related requirements can affect market access and demand segmentation.Maintain a regulatory matrix for key destination markets, map product naming/INS/E-number/CAS identifiers consistently, and monitor Codex/JECFA updates alongside major market regulators.
Trade Data Opacity MediumGlobal trade statistics often capture tricalcium citrate within aggregated HS categories such as HS 291815 (salts and esters of citric acid), which includes multiple citrate salts and esters. This aggregation reduces visibility into true product-specific supply concentration and can mask abrupt shifts between substitute citrate salts in reported trade patterns.Use supplier- and buyer-level intelligence (company shipment data, contracts, and customs line-item details where available) to complement HS-level trade statistics.
FAQ
What is tricalcium citrate used for in food manufacturing?FAO/WHO JECFA lists calcium citrate (tricalcium citrate; INS 333) with functional uses including sequestrant, buffer, and firming agent. The U.S. FDA’s food-substance inventory also lists technical effects such as firming agent, nutrient supplement, pH control agent, and sequestrant for calcium citrate/tricalcium citrate.
What is the Codex/INS identifier for tricalcium citrate?FAO/WHO JECFA identifies calcium citrate (tricalcium citrate) as INS 333.
Why do trade statistics often use HS 291815 for this product?Global trade datasets commonly report citrate salts under HS 291815 (“salts and esters of citric acid”), which can include calcium citrate/tricalcium citrate along with other citrate salts and citrate esters. World Bank WITS (UN Comtrade) publishes import and export statistics for HS 291815, but HS 6-digit data does not isolate tricalcium citrate alone.
