HS Code for Pre-tanning enzyme

Pre-tanning enzymes are classified under HS code 3202.90, which covers enzymatic preparations for pre-tanning. While enzymes as pure chemical substances are generally found in Chapter 35 (specifically 3507), the Harmonized System provides a specific carve-out for preparations used in the leather industry. Heading 3202 includes synthetic organic tanning substances and inorganic tanning substances, but the subheading 3202.90 is specifically designed to capture enzymatic bates and other preparations used to prepare hides and skins before the actual tanning occurs. These enzymes, such as proteases or lipases, are used to remove unwanted proteins and fats from the skin, a process known as bating. The classification under 3202.90 is determined by the product's formulation as a preparation intended for this specific industrial application, often containing the enzyme mixed with a carrier like wood flour or kaolin.

Products Included

• Enzymatic bates for leather processing
• Proteolytic enzyme preparations for dehairing
• Lipolytic enzymes for degreasing hides
• Pre-tanning softening agents containing enzymes

Common Misclassification

The most common misclassification is 3507.90, which covers general enzymes. However, the Explanatory Notes to the HS state that enzymatic preparations specially formulated for tanning must be classified in 3202. Another error is 3202.10, which is reserved for synthetic organic tanning substances (syntans), which are chemically distinct from enzymatic preparations.

FAQ

What is the HS code for Pre-tanning enzyme?

The HS code for pre-tanning enzymatic preparations is 3202.90.

Can pure enzymes be classified here?

Generally, pure enzymes are 3507; 3202.90 is for preparations specifically formulated for the pre-tanning or bating process in leather production.
