Styrene oxide

Styrene Oxide (CAS No. 96-09-3) is a critical chemical intermediate. B2B buyers should prioritize a purity level of ≥99% to ensure reaction stability in epoxy resin or fragrance synthesis. Key parameters include a refractive index of 1.533-1.536 and a moisture content of <0.1%. High-quality suppliers on Made-in-China.com typically provide a Certificate of Analysis (COA) for every batch to verify these specifications.

As a hazardous chemical, Styrene Oxide must comply with the GHS (Globally Harmonized System) for classification and labeling. It is often classified under UN Number 2810 (Toxic Liquid, Organic, N.O.S.). Buyers must ensure the supplier provides a Safety Data Sheet (SDS) compliant with REACH (EU) or OSHA (US) standards. Verification of ISO 9001 for quality management and ISO 14001 for environmental management is highly recommended.

It is predominantly used as a reactive diluent for epoxy resins, an intermediate in the production of pharmaceuticals (like levamisole), and in the synthesis of fragrances and flavors (such as phenethyl alcohol). Its ability to undergo ring-opening reactions makes it essential for polymer cross-linking and the production of UV-curable coatings.

Styrene Oxide is chemically active and can polymerize exothermically. It must be stored in cool, well-ventilated warehouses away from fire and heat sources. The storage temperature should ideally be below 25°C. Suppliers should use stainless steel or specially coated drums to prevent contamination and ensure the product is kept under an inert gas blanket (like Nitrogen) to extend shelf life.

Due to its classification as a Class 6.1 toxic substance (or Class 3 flammable depending on flash point and local laws), it requires IMDG-compliant packaging. You must use freight forwarders experienced in Dangerous Goods (DG) handling. Ensure the supplier provides a Dangerous Goods Declaration and uses UN-certified drums to avoid port rejection or heavy fines.

Utilize Trade Assurance services provided by platforms like Made-in-China.com to protect your payment until delivery is confirmed. Always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek to verify the chemical purity and drum integrity before the balance payment is released.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate based on annual volume commitments to secure a 10-15% discount compared to spot pricing. Ask for tiered pricing (e.g., 1-5 tons vs. 20+ tons) and clarify if the price includes specialized DG packaging and export licensing fees.

Check for Anti-Dumping Duties (ADD) that may apply between the exporting and importing countries. Ensure the supplier is capable of providing a Certificate of Origin (CO) to benefit from preferential tariffs under Free Trade Agreements. Failure to have a valid Import License for hazardous chemicals in your home country can lead to customs seizure.
