Carboxylated Styrene-Butadiene Latex (XSBR Latex)
XSBR latex features carboxylic acid groups on SBR particles for enhanced adhesion in water-based coatings and textiles. Classified in HTS 4002.11.00.00 as it represents SBR latex (explicitly including XSBR per heading description) in primary dispersion form, retaining raw material character per Chapter notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If butyl rubber latex form
Different synthetic rubber polymer types separate into specific subheadings like 4002.91 for butyl.
If surface-worked or pigmented beyond identification purposes
Chapter note 5(a)(ii) excludes colored latex from primary forms, shifting to paints/varnishes in Chapter 32.
If compounded with vulcanizing agents for XSBR-specific applications
Prevulcanized latex with cross-linking agents classifies as compounded rubber in 4005, not raw 4002.

Import Tips & Compliance
• Include FTIR spectroscopy or equivalent to prove carboxylation on SBR base without prohibited extenders per note 5(b)
• Declare exact solids content (typically 40-50%) and confirm no cross-linking agents that would alter primary form status
• Watch for EU REACH compliance if transshipping; mismatched chemical passports trigger holds
