BR and SBR cost centres hinge on butadiene (C4 fraction) supply, with cracker runs and light-feed share setting marginal cost; when NR is expensive, tyre makers raise synthetic blend ratios to control cost.

Replacement demand from passenger and commercial vehicles underpins consumption, but oversupply in commodity SR concentrates margins among integrated producers; high-end solution-SBR (SSBR) use in green tyres is steadily rising.

SNSUC places natural and synthetic rubber in one supply-chain view with blockchain attestation and digital warrants, helping tyre and goods makers manage quality and delivery certainty while comparing prices.
