HS Code 3507.10 – Enzymes; rennet and concentrates thereof
HS code 3507.10 is the 6-digit subheading for enzymes, rennet and concentrates thereof. It is used for liquid calf rennet, microbial rennet powder, chymosin enzyme concentrate, rennet tablets and fungal rennet.
What HS 3507.10 covers
This HS code covers rennet and its concentrates, which are crucial enzymes primarily used in the dairy industry for coagulating milk during cheese production. Rennet facilitates the separation of curds and whey, a fundamental step in cheesemaking. International trade in rennet is driven by the global demand for cheese, with major dairy-producing nations being significant importers. Exporters typically include countries with advanced biotechnology and enzyme manufacturing capabilities. Key things to know include the shift from animal-derived rennet (calf rennet) to microbial or genetically engineered chymosin, driven by cost, availability, and vegetarian preferences. Regulatory standards for food additives and processing aids are paramount, influencing market access and product formulation globally. The trade often involves specialized chemical and food ingredient companies.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
