Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in solid primary forms like granules or powder
NBR in non-latex primary forms like crumbs or bales shifts to other synthetic rubber categories outside latex.
If heavily modified with adhesives or proteins for gluing
Prepared glues or adhesives containing rubber latex fall under Chapter 35, not raw synthetic rubber.
If classified as a chemical insecticide carrier
Rubber latex used in pesticidal formulations is excluded and classified under chemical products.

Import Tips & Compliance
• Verify the latex is uncompounded with vulcanizing agents, pigments, or fillers beyond permitted additives to maintain primary form classification
• Provide certificate of analysis confirming NBR composition and prevulcanization status to avoid reclassification as a finished article
• Check for restrictions on medical-grade materials; ensure documentation matches end-use declarations
