Import Bismuth Powder — Buy in wholesale FOB from Supplier in China

Guangzhou Litop Non-Ferrous Metals Co., Ltd. supplies bismuth powder at 99.99% purity with a particle size range of 100-600 mesh, translating to approximately 25-150 micrometres depending on the sieve standard applied. The material has a density of 9.75 g/cm³, melts at 271.52 °C, and boils at 1564 °C, with vacuum poly-bag packaging specified for oxidation protection. This broader particle size spread compared to specialty narrow-fraction powders makes it suitable for applications where some size variation is acceptable or where downstream milling is planned.

The powder is derived from refined bismuth metal, with the 100-600 mesh specification indicating a coarser, more commercially oriented product than ultrafine grades. Bismuth's low melting point, benign toxicity profile relative to lead, and diamagnetic properties underpin its use in fusible alloys, radiopaque contrast media, and low-temperature solder formulations. The density figure of 9.75 g/cm³ is consistent with theoretical bismuth density, though actual powder packing density will be lower due to interparticle voids. Vacuum packaging is essential as bismuth surfaces oxidise to Bi₂O₃ in ambient conditions, degrading powder quality.

Target buyers include low-melting alloy manufacturers, pharmaceutical compounders requiring coarse feedstock for subsequent micronisation, radiation shielding fabricators, and fireworks or pyrotechnic producers exploiting bismuth's crackling effects. The 100-600 mesh range suits gravity settling applications, coarse thermal spray, and initial alloy melting where rapid dissolution is desired. Importers should note the absence of specified D50 or uniformity data, and confirm whether the supplier provides blended narrow cuts from this broad range or sells as-sieved bulk product.

Guangzhou Litop Non-Ferrous Metals Co., Ltd. operates from Unit 211, Building D, Jing Sheng Creative Park, No. 2801 East Huang Pu Road, Guangzhou 510730, Guangdong Province, China. The supplier carries both imported and harbor tier classifications, suggesting some combination of direct manufacturing and trading operations, with a harbor trust tier on the platform. Response metrics show 0.00% response rate with zero average response hours, indicating either a new listing or limited platform-based enquiry management. The creative park address suggests office or light processing facilities rather than heavy industrial production.

The company profile does not disclose founding date, registered capital, production capacity, number of employees, or specific quality management certifications such as ISO 9001. No client list, export volumes, or manufacturing equipment details are provided. Buyers should independently verify whether Litop operates its own atomisation or milling equipment, or sources powder from upstream smelters. The Guangdong location offers logistics advantages via Guangzhou Port or Shenzhen for sea freight, and proximity to Hong Kong for air cargo.
