Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If minimally compounded synthetic rubber
Pure SBR without fillers qualifies under 4002 synthetic rubber primary forms.
If vulcanized into forms like plates or rods
Vulcanized versions move to 4007 for unhardened rubber in plates, sheets, etc.
If deteriorated into unusable scrap
Becomes 4004 waste if not suitable for direct use due to wear per note 6.

Import Tips & Compliance
• Weigh bales precisely for entry declarations; test for vulcanization levels if disputed
• Certify no vulcanizing agents present to stay in 4005
• Common pitfall: mislabeling as natural rubber bales under 4001
