Formic acid 85%\90%

Buyers must prioritize purity levels (85% or 90%) and check for impurity limits, specifically acetic acid content (<0.4%) and heavy metals (<0.001%). Ensure the product is a clear, colorless liquid with no visible suspended solids. For high-end applications like textiles or pharmaceuticals, request a Certificate of Analysis (COA) for every batch to confirm the acid value and density (approx. 1.22 g/cm³ for 90% concentration).

As a hazardous chemical, Formic Acid must comply with the GHS (Globally Harmonized System) for labeling and packaging. Ensure the supplier provides a valid MSDS (Material Safety Data Sheet). For export, verify the UN Number (UN 1779) and Hazard Class (Class 8 Corrosive, Sub-risk Class 3 Flammable). If importing to Europe, the supplier must be REACH compliant; for the US, check for TSCA (Toxic Substances Control Act) inventory status.

Formic Acid is highly corrosive. Ensure the supplier uses acid-resistant packaging such as HDPE (High-Density Polyethylene) drums (25kg, 35kg, or 250kg) or IBC tanks (1200kg). For large-scale liquid transport, ISO tanks are recommended. Verify that the packaging is UN-certified for hazardous goods to prevent leaks during long-distance cross-border transit.

85% Formic Acid is widely used in the leather industry for tanning and fixing, as well as in rubber coagulation. The 90% concentration is more common in pharmaceutical synthesis, pesticide production, and as a silage additive in agriculture. Choosing the correct concentration is vital for chemical reaction efficiency and cost-effectiveness in your specific production line.

Formic Acid is classified as Dangerous Goods (DG). You must use a freight forwarder with DG handling qualifications. Shipping risks include temperature sensitivity (it may fumes at high temperatures) and leakage hazards. Ensure the vessel is equipped for Class 8 chemicals and that the stowage position is away from heat sources and reactive chemicals like strong alkalis or oxidizers.

Always select Audited Suppliers on Made-in-China.com who have undergone third-party verification by agencies like SGS or Bureau Veritas. Use Secured Trading Services to protect your payment until the goods are shipped. Before placing a bulk order, request a pre-shipment inspection (PSI) to verify the concentration and net weight at the loading port.

Chemical prices fluctuate with raw material costs (like methanol and carbon monoxide). Negotiate a formula-based pricing model or a volume-based discount (e.g., 5-10% off for full container loads). Discuss lead times clearly, as hazardous goods often require special booking windows with shipping lines, typically needing 14-21 days advance notice.

Check the HS Code (2915110000) for specific import duties in your country. Be aware of Anti-Dumping Duties (ADD) that some regions may impose on chemical imports from specific origins. Ensure all Export Licenses for hazardous chemicals are prepared by the Chinese supplier to avoid delays at China Customs during the exit inspection.
