HS Code for Casein glue

Casein glue is classified under HS code 350190. This code is situated within Chapter 35, which covers albuminoidal substances, modified starches, glues, and enzymes. Heading 3501 specifically covers casein, caseinates, and other casein derivatives. Casein is a phosphoprotein found in milk, and when it is reacted with alkaline substances, it produces a highly effective adhesive known as casein glue. The classification under 350190 is appropriate because it specifically identifies casein glues as a derivative of the base protein. This classification is distinct from general-purpose adhesives because of the specific biological origin of the primary ingredient. Casein glues are valued for their moisture resistance and are traditionally used in woodworking, bottle labeling, and aircraft construction. The technical nature of the substance—being a milk-derived protein adhesive—is the primary driver for its placement in heading 3501 rather than the general glue heading of 3506. Customs authorities look for the presence of caseinates to confirm this classification.

Common Misclassification

Casein glue is often misclassified under HS code 3506, which covers prepared glues and other prepared adhesives not elsewhere specified. However, because casein glue is specifically mentioned as a derivative in 3501, the more specific code 350190 takes precedence. It may also be confused with HS code 3505, which covers dextrins and other starch-based glues, but the protein versus carbohydrate origin distinguishes them.

FAQ

What is the HS code for casein glue?

The specific HS code for casein glue and caseinates is 350190.

Is casein glue the same as white PVA glue?

No, white PVA glue is a synthetic polymer and is classified under HS code 350691, whereas casein glue is a natural protein-based adhesive.
