Styrene price manufacturers

When sourcing Styrene, the purity level is the most critical factor, typically requiring a minimum of 99.8%. You must also verify the Polymer Content (should be <10 mg/kg) and the Color (Pt-Co), which should ideally be below 10. Additionally, check the Inhibitor Content (TBC - Tertiary Butyl Catechol); it is usually maintained between 10-15 ppm or 45-55 ppm depending on the transport distance and temperature to prevent premature polymerization.

Styrene is a hazardous chemical (UN Number 2055, Class 3 Flammable Liquid). Ensure the supplier provides a Material Safety Data Sheet (MSDS) compliant with GHS standards. For buyers in the EU, REACH registration is mandatory. If the end product is for food packaging (like PS or ABS), ensure the monomer meets FDA or EU 10/2011 food contact regulations regarding residual monomer limits.

The price of Styrene is highly volatile and primarily driven by upstream feedstock costs (Benzene and Ethylene). Other factors include crude oil price fluctuations, regional supply-demand balances, and plant maintenance schedules (turnarounds). Buyers should monitor the ICIS or Platts benchmarks and consider formula-based pricing versus spot pricing to manage financial risk.

Styrene has a limited shelf life due to its tendency to polymerize. It must be stored in stainless steel or specially coated carbon steel tanks at temperatures below 25°C. Suppliers must ensure oxygen levels in the tank headspace are maintained (typically 3-8%) because the TBC inhibitor requires oxygen to function effectively. Always ask for the latest batch production date to ensure freshness.

Use Made-in-China.com's Secured Trading Services to ensure payment safety. Always request a Third-Party Inspection Report (such as SGS or Intertek) at the loading port to verify the purity and inhibitor levels before the final payment is released. This prevents disputes regarding off-spec material upon arrival.

Styrene must be shipped in ISO Tanks or specialized Chemical Tankers. Ensure the logistics provider is certified for Dangerous Goods (DG) handling. For long-haul cross-border shipping, verify that the supplier has added extra inhibitor and provided a Temperature Log to prevent the 'runaway polymerization' risk during transit through tropical zones.

Focus on Incoterms; while CIF is convenient, FOB or CFR might offer better transparency if you have a reliable freight forwarder experienced in chemicals. Negotiate volume-based rebates and ask for a fixed-margin over the Benzene index if you are looking for a long-term contract to stabilize your supply chain costs.
