Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If manufacturing crumbs/ powder waste
Powder from wear or cutting during BR working is waste per note 6.
If chemical dispersion with non-rubber
BR in prepared chemical mixtures loses pure rubber status for Chapter 38.
If ISR co-polymer form
Isoprene-butadiene copolymers have separate provisions from pure BR.

Import Tips & Compliance
• Particle size analysis required to confirm powder vs. granules distinction
• Avoid bulk packaging that suggests plates/sheets (4008) by using bags only
• Certify no plasticizers/extenders beyond mineral oil for oil-extended BR
