Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If starch-based rather than casein-derived
Starch glues fall under dextrins and starch glutinous preparations, changing heading based on primary binder material.
If sold as prepared adhesive binder for retail use
Retail-packaged chemical preparations like casein mixes may classify as chemical goods of heading 3824 if not purely casein glues.
If peptones or protein derivatives dominate
Caseinates or derivatives shift to heading 3504 when used as isolates rather than formulated glues.
