HS Code for Serum albumin

Serum albumin is classified under HS code 3502.90. This heading covers albumins, albuminates, and other albumin derivatives. Albumins are proteins that are soluble in water and concentrated salt solutions. Serum albumin, specifically, is the main protein found in blood plasma and is widely used in laboratory research, diagnostics, and medical treatments. The classification 3502.90 is a residual category for albumins other than egg albumin (3502.11/19) and milk albumin (3502.20). This code includes both human serum albumin (HSA) and bovine serum albumin (BSA). The classification is determined by the chemical nature of the product as a protein derivative rather than its biological origin as a blood fraction, provided it has been purified to a certain degree. If the product is unrefined or contains other blood components, it may shift to a different chapter.

Products Included

• Bovine Serum Albumin (BSA) in powder or solution form
• Human Serum Albumin (HSA) for laboratory use
• Albuminates (salts of albumin)
• Purified serum protein fractions
• Concentrates of whey protein containing more than 80% protein

Common Misclassification

Serum albumin is frequently misclassified under HS code 3002.12, which covers antisera and other blood fractions. The distinction depends on the level of purification and the intended use. According to the Explanatory Notes to Chapter 35, albumin is excluded from Chapter 30 if it is not prepared for therapeutic or prophylactic uses or if it is a highly purified protein. Another common error is using 3502.11 for egg albumin (ovalbumin), which is a different protein source entirely. Importers must ensure the source (serum vs. egg vs. milk) is clearly documented to avoid these errors.

FAQ

What is the HS code for Serum albumin?

The HS code for serum albumin, including BSA and HSA, is 3502.90.

Is medical-grade human albumin classified here?

If the human albumin is prepared for therapeutic use (e.g., for infusions), it is often classified under 3002.12. However, if it is a pure chemical/protein for lab use, 3502.90 applies.
