Import Barium Sulfate — Buy in wholesale FOB from Supplier in China

Shanghai Tengmin Industry Co., Ltd. supplies precipitated (synthetic) barium sulfate, identified as grade A10, from its location on Cao'an Road in Shanghai, China. The material is characterised as a high-purity white powder produced by advanced technology with quality control exceeding GB (Guobiao) national standards. The supplier emphasises chemical resistance to acids and alkalis, lightfastness, weather resistance, and extremely high purity with pure brightness and whiteness. Key stated attributes include superior and uniform fineness, good dispersion and compatibility, and ultra-low oil absorption.

The A10 grade is positioned for demanding applications in decorative architectural coatings (interior and exterior), marine and protective coatings, powder coatings, solvent-based printing inks, water and solvent-based industrial coatings, plastics, masterbatch, rubber, and decorative laminating base paper. The synthetic production route, as opposed to natural barite grinding, enables tighter control over particle morphology, purity, and surface properties. Standard precipitated barium sulfate for these sectors typically carries BaSO4 purity above 98.5%, with controlled median particle size in the sub-micron to low-micron range, and specific surface area tuned to application requirements.

Buyers evaluating this grade should focus on the technical documentation package: certificate of analysis with batch-specific data, material safety data sheet, and any available third-party test reports. The listing does not state MOQ, price, lead time, or packaging formats. Prospective importers must confirm these directly with Shanghai Tengmin, along with Incoterms, port of shipment, and payment structure. Given the supplier's emphasis on exceeding GB standards, request the actual test protocol and comparator data to verify this claim against standard GB/T 2899 or HG/T 2774 specifications for precipitated barium sulfate.

Shanghai Tengmin Industry Co., Ltd. is located at No.1855 Cao'an Road, Shanghai 201800, China. The supplier holds harbor trust tier classification. No response rate or average response time data is available in the profile, indicating no recorded inquiry history. The company does not disclose manufacturing site details, production capacity, year of establishment, employee numbers, or revenue figures.

The listing focuses on technical product attributes rather than corporate credentials. No quality management certifications (ISO 9001, ISO 14001), export license details, or named customer references are provided. The supplier presents the A10 grade as exceeding GB standards, but does not cite specific standard numbers or publish third-party verification. Buyers should conduct independent due diligence on company registration, manufacturing scope, and quality system certification before placing orders. Request factory audit reports or third-party inspection certificates if available.
