Product classification
HS code for Industrial enzymes: 3507.90
Enzymes and prepared enzymes, other than rennet and concentrates thereof.
Classification of industrial enzymes under HS 3507.90
Industrial enzymes are classified under HS code 3507.90. This heading covers enzymes and prepared enzymes that are not elsewhere specified. Enzymes are biological catalysts used in various industrial processes, including food production, textile manufacturing, and detergent formulation. Subheading 3507.90 is the residual category for enzymes other than rennet (3507.10). The classification includes both pure enzymes and preparations with added substances like stabilizers, activators, or substrates, provided they are not covered by more specific headings. These products are essential in modern manufacturing for breaking down proteins, fats, or starches. The classification is determined by the chemical nature of the product as a protein-based catalyst. Even if the enzyme is used in the pharmaceutical industry, it remains in 3507 unless it is put up in measured doses or in forms for retail sale as a medicament.

Codes often confused with 3507.90
Common mistake. Industrial enzymes are sometimes misclassified under 2936 (vitamins) or 2937 (hormones) due to their biological origin, but enzymes have a distinct catalytic function. Another common error is 3004, which covers medicaments. If the enzyme is for industrial use and not for therapeutic or prophylactic use in humans or animals, it must stay in 3507. Additionally, 3808 (disinfectants) is sometimes used for enzymes in cleaning products, but 3507.90 is the correct code for the enzyme preparation itself before it is formulated into a finished disinfectant.
Top exporters and importers of HS 350790 (the code used for industrial enzymes), 2025
In 2025, the largest exporter of HS 350790 (the code used for industrial enzymes) in UN Comtrade data was Denmark, with 21% of world exports; the largest importer in UN Comtrade data was the Netherlands, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 350790, not only industrial enzymes.

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).

Questions about industrial enzymes
What is the HS code for Industrial enzymes?
The HS code for Industrial enzymes is 350790 (Enzymes and prepared enzymes; other than rennet and concentrates thereof). The HS code for industrial enzymes, excluding rennet, is 3507.90.
How do I classify Industrial enzymes for customs?
Industrial enzymes is classified under HS code 350790 — Enzymes and prepared enzymes; other than rennet and concentrates thereof. This is a 6-digit subheading level code.
Are enzymes for food use classified differently?
No, enzymes used as processing aids in the food industry are still classified under 3507.90, provided they are not retail-ready food additives.
Which countries are the top exporters of industrial enzymes (HS 350790)?
In 2025, the top exporters of HS 350790 (the code used for industrial enzymes) in UN Comtrade data were Denmark ($1.7B, 21% of world exports), the Netherlands ($1.2B) and the United States ($1.1B). World exports came to about $8.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
