U.S. imports of Styrene-Butadiene Rubber (SBR / XSBR) in Primary Forms, Excluding Latex (HS 400219) totaled $59.2M in August 2026, imported from 29 countries.
Importers of Styrene-Butadiene Rubber (SBR / XSBR) in Primary Forms, Excluding Latex paid $5.0M in duties in August 2026, an average duty rate of 8.49% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Styrene-Butadiene Rubber (SBR / XSBR) in Primary Forms, Excluding Latex imports of $59.2M in August 2026 ran 18% above the year-to-date monthly average of $50.0M.
Last updated: August 2026 dataSolid and semi-solid SBR — including emulsion-polymerized E-SBR, solution-polymerized S-SBR, and styrene-butadiene-styrene (SBS) block copolymers — is the dominant synthetic rubber in passenger tire treads and a key input for footwear, belting, and asphalt modification. South Korea leads US imports, followed by Mexico and Germany. The US schedule is notably granular: S-SBR in bales (4002191600), SBS thermoplastic elastomer granules and crumbs (4002191400), E-SBR with ≤50% styrene (4002190015), and higher-styrene variants (4002190020) each carry separate lines, making precise polymer type and styrene content critical classification inputs. S-SBR's superior wet-grip and rolling-resistance profile has driven its adoption in high-performance tire compounds, creating distinct demand patterns from commodity E-SBR.

The US schedule draws a key line at 50% styrene by weight of dry polymer. E-SBR at or below 50% styrene falls under 4002190015, while SBR exceeding 50% styrene is classified under 4002190020. S-SBR in bales has its own dedicated line (4002191600) regardless of styrene content. Suppliers should provide a certificate of analysis confirming styrene percentage to support the correct classification.
SBS (styrene-butadiene-styrene) block copolymers are thermoplastic elastomers — they behave as rubber at service temperatures but can be melt-processed like thermoplastics — whereas conventional SBR is a thermoset-processable random copolymer. The 4002191400 line specifically covers SBS in granule, crumb, or similar forms used in asphalt modification, adhesives, and footwear soles. Importers should confirm the block vs. random copolymer architecture in supplier technical data sheets to avoid misclassification.
