HS Code for Milk protein

Milk protein, specifically in the form of casein, is classified under HS code 3501.10. This classification is part of Chapter 35, which covers albuminoidal substances, modified starches, glues, and enzymes. Casein is the principal protein found in milk and is typically produced by the precipitation of skimmed milk using acids, rennet, or other enzymes. Heading 3501 specifically includes casein, caseinates, and other casein derivatives, as well as casein glues. Subheading 3501.10 is dedicated to the raw or isolated casein itself. This classification is distinct from the dairy products found in Chapter 4, such as milk, cream, and whey. While Chapter 4 covers products that are essentially food items in their natural or minimally processed state, Chapter 35 focuses on isolated chemical components and proteins intended for industrial, pharmaceutical, or specialized food applications. The transition from Chapter 4 to Chapter 35 occurs when the protein is isolated to a high degree of purity, transforming it from a dairy product into a chemical substance. This distinction is vital for customs purposes, as it affects duty rates and regulatory requirements. The classification follows General Interpretative Rule 1, prioritizing the specific chemical identity of the substance over its biological origin.

Products Included

• Acid casein
• Rennet casein
• Isolated milk protein (casein-based)
• Industrial grade casein
• Edible casein for food fortification

Common Misclassification

Casein is frequently confused with whey protein, which is classified under HS code 0404.10 or 3502.20 depending on its concentration and state. Another common misclassification is HS code 3501.90, which is reserved for caseinates and derivatives rather than the base protein. It is also important not to confuse casein with milk powders classified in Chapter 4, which contain fats, sugars, and other milk solids in addition to protein.

FAQ

What is the HS code for Milk protein?

The HS code for milk protein in the form of casein is 3501.10.

Is whey protein classified under the same code?

No, whey protein is classified differently. If it is a whey protein concentrate with a protein content over 80%, it is usually classified under 3502.20; otherwise, it falls under 0404.10.
