Styrene-Butadiene Latex (SBR Latex)
Styrene-butadiene latex is a water-based dispersion of synthetic rubber copolymer used primarily in the production of latex gloves, adhesives, and paper coatings. It qualifies under HTS 4002.91.00.00 as a synthetic rubber latex in primary form, meeting the vulcanization and elasticity criteria outlined in chapter notes for synthetic rubber.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in plates, sheets, or strip form rather than liquid dispersion
Chapter note 8 specifies plates/sheets/strip exclude dispersions like latex, moving to 'other' primary forms.
If heavily modified with adhesives or polymers beyond rubber essential character
Prepared glues/adhesives fall outside Chapter 40 per note 1 exclusions if no longer primarily rubber latex.
If when used as paint/coating with pigments beyond identification purposes
Chapter note 5(a)(ii) excludes latex with coloring matter not solely for ID, shifting to Chapter 32 paints.

Import Tips & Compliance
• Verify the latex meets synthetic rubber criteria per chapter note 2 (vulcanization test) with lab documentation to avoid reclassification
• Provide certificates of analysis showing no prohibited additives like vulcanizing agents beyond permitted levels (chapter note 5)
