SBR 1502 Latex
SBR 1502 is a styrene-butadiene rubber latex dispersion containing less than 50% styrene in the dry polymer, used primarily in paper coatings and adhesives. It qualifies under HTS 4002.19.00.19 as a synthetic rubber in primary liquid form, meeting the chapter's definition for prevulcanized latex without prohibited compounding agents. This excludes it from Chapter 39 plastics due to its vulcanizable rubber properties.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If styrene content exceeds 50% by dry weight
Higher styrene ratio in SBR places it in the 'more than 50% styrene' subheading within the same SBR category.
If non-vulcanizable and treated as synthetic polymer
Fails rubber chapter vulcanization/elongation test, classifying as styrene polymers in Chapter 39 instead of synthetic rubber.
If compounded with vulcanizing agents or fillers
Addition of prohibited substances like accelerators or extenders changes it from primary form to compounded rubber.

Import Tips & Compliance
• Verify styrene content certificate from manufacturer showing ≤50% by dry weight; ensure no vulcanizing agents beyond permitted additives to maintain primary form status
• Common pitfall: misdeclaration as compounded rubber shifts to 4005
