Bisphenol A (BPA)

双酚A

Bisphenol A is the precursor to polycarbonate resin, epoxy resin, and a wide range of phenolic intermediates. Chinese capacity has grown rapidly with the polycarbonate chain expansion; Chiu Shun, Wanhua, Sinopec, and Yangtze River complexes hold the bulk of capacity. UN 3077 if classified as environmentally hazardous in solid form, otherwise non-dangerous-goods for the solid flake or pellet. Ships in 25 kg PE bags or 1 t big bags. The EU REACH SVHC listing for endocrine-disruptor concerns drives downstream consumer-product reformulation pressure; verify against the ECHA SVHC candidate list before invoicing EU shipments. US imports do not carry Section 301 on bulk BPA at the time of writing. This cluster aggregates CAS 80-05-7 across the regulatory matrix.
