Import Dmso / Dimethyl Sulfoxide — Buy in Bulk from Supplier in China

Dimethyl sulfoxide (DMSO) is a non-protonic polar solvent with high solubility in both water and organic media, supplied by Hebei Tianao Technology Co., Ltd as a reagent-grade chemical with a purity of at least 99.5%. The product exhibits a boiling point of 189°C, a freezing point of 18.5°C, and a water content below 0.1%, consistent with industrial-grade specifications. Its refractive index is approximately 1.479 at 20°C, and it has a low viscosity that supports easy handling in continuous processing systems.

This DMSO is produced through the catalytic oxidation of dimethyl sulfide, a standard industrial method. It contains no detectable sulfur compounds or aldehydes, which could interfere with sensitive chemical reactions. Typical industry variants include anhydrous and stabilized grades; this product is anhydrous and stored under nitrogen to prevent moisture uptake. It meets the purity benchmarks for use in pharmaceutical synthesis and polymer processing, though no third-party certification is confirmed by the supplier.

DMSO from this supplier is primarily used as a solvent in acrylic polymerization, dye extraction, and as a carrier in pesticide formulations. Buyers include chemical manufacturers in Asia and Europe that require a reliable solvent for resin synthesis and organic reactions. Packaging is in 200kg steel drums with inner polyethylene liners. Trade terms are typically FOB Tianjin, with minimum order quantities of one full container load. Lead time is confirmed as 10 to 15 days after payment, subject to production scheduling.

Hebei Tianao Technology Co., Ltd is a chemical manufacturer based in Hebei Province, China, with a verified harbor trust tier indicating compliance with basic export documentation standards. The supplier has no publicly listed certifications for ISO, GMP, or REACH, and no information is provided on production capacity, workforce size, or years in operation. Their listing confirms direct export capability but does not claim client names or industry awards.

The company focuses on bulk chemical supply, particularly solvents and intermediates for industrial applications. Their DMSO is produced in-house, though no details on plant location or process controls are disclosed. Response rates and communication metrics are not tracked in the system, suggesting limited buyer engagement infrastructure. Buyers should treat this as a direct manufacturer with no verified quality assurance systems beyond standard export compliance.
