Chemical methylene chloride solvent

Buyers must prioritize purity levels, typically requiring ≥99.9% for industrial and pharmaceutical grades. Key parameters include moisture content (≤100 ppm), acidity (≤10 ppm as HCl), and non-volatile residue (≤10 ppm). Ensure the product is stabilized (usually with amylene or cyclohexane) to prevent decomposition during long-term storage or transport.

As a hazardous chemical, it must comply with the GHS (Globally Harmonized System) for labeling and packaging. Suppliers must provide a comprehensive SDS (Safety Data Sheet). For specific markets, verify REACH registration (EU), TSCA compliance (USA), and ensure the manufacturer holds ISO 9001 (Quality) and ISO 14001 (Environmental) certifications.

It is widely used as a paint stripper and degreaser due to its high solvency. In the pharmaceutical industry, it serves as a process solvent for antibiotic and vitamin production. Other major applications include polyurethane foam blowing, adhesive manufacturing, and as an extraction solvent in the food and beverage industry (decaffeination), though the latter requires strict Food Grade certification.

Request a COA (Certificate of Analysis) for every batch. For large-scale B2B procurement, it is highly recommended to engage third-party inspection services like SGS or Intertek to perform pre-shipment sampling and testing. Focus on color (APHA ≤10) and refractive index to ensure no contamination occurred during the filling process.

Methylene Chloride is classified under UN Number 1593, Class 6.1 (Toxic Substances). It must be packed in UN-approved galvanized iron drums (250kg/270kg) or ISO Tanks for bulk shipments. Ensure the containers are hermetically sealed to prevent evaporation and that the vessel is equipped to handle IMDG-regulated cargo.

Utilize Made-in-China.com's secured payment services to protect your funds until delivery. Conduct a factory audit or request a Verified Supplier report to confirm the manufacturer has the legal license to export hazardous chemicals. Avoid suppliers offering prices significantly below the global market index, as this often indicates recycled or sub-standard purity.

Many countries have strict import permits for chlorinated solvents due to environmental regulations. Verify if your country imposes anti-dumping duties on Chinese chemicals. Ensure all export documentation, including the Commercial Invoice, Packing List, and Dangerous Goods Declaration, matches the SDS exactly to avoid customs seizures or heavy fines at the port of entry.

Chemical prices are highly sensitive to raw material costs (Chlorine and Methanol) and energy prices. Negotiate based on volume tiers (e.g., 20ft FCL vs. ISO Tank) and consider long-term contracts to hedge against price volatility. Always clarify if the quoted price is FOB or CIF, as freight for hazardous goods can account for 20-40% of the total landed cost.
