HS Code for Tanning preparation

Tanning preparations that are not purely vegetable-based or are inorganic in nature are classified under HS code 3202.90. This heading covers a broad range of chemical products used in the leather industry to prepare hides for tanning or to perform the tanning process itself using mineral or enzymatic methods. Unlike heading 3201, which is restricted to vegetable extracts, heading 3202 includes synthetic organic tanning substances, inorganic tanning substances (such as chromium salts), and enzymatic preparations. The subheading 3202.90 is a residual category for inorganic tanning substances and complex preparations that may contain natural tanning materials but are formulated with additional chemicals to enhance their performance. This classification is essential for products like chrome tanning salts, which are the most common mineral tanning agents used globally.

Products Included

• Chrome tanning salts (basic chromium sulfate)
• Aluminum-based tanning salts
• Zirconium tanning preparations
• Enzymatic pre-tanning preparations (bates)
• Inorganic tanning substances mixed with organic salts
• Pre-tanning preparations containing enzymes for de-hairing

Common Misclassification

A common mistake is classifying these chemical preparations under 3201.90. However, 3201 is strictly for vegetable extracts; any preparation containing inorganic salts or enzymes must move to 3202. Another frequent error is confusing 3202.90 with 3202.10. HS code 3202.10 is specifically for synthetic organic tanning substances (often called \"syntans\"), which are man-made polymers. If the preparation is based on inorganic minerals like chromium or aluminum, 3202.90 is the correct code. Additionally, simple chemicals like sodium sulfide used in the beamhouse are classified in Chapter 28, not as tanning preparations in 3202.
