    Sodium Tungstate — Japan

    Japanese specialty chemical manufacturers producing corrosion inhibitor formulations for automotive cooling systems, industrial water treatment, and precision metalworking fluids use sodium tungstate dihydrate (Na₂WO₄·2H₂O, assay min. 99%) as an anodic inhibitor component, valued for its effectiveness in protecting aluminium alloy and ferrous metal surfaces in mixed-metal cooling circuits used in Japanese automotive and electronics manufacturing. Jayanth Tungsten supplies sodium tungstate as white crystalline powder with assay, WO₃ content (~71.8% calc.), and molecular weight (329.86 g/mol) confirmed on the certificate of analysis, with HS 2841 documentation for Japanese customs clearance via Yokohama or Osaka.

    Export packaging & documentation

    Sodium tungstate dihydrate is supplied as white crystalline powder (assay min. 99%) in sealed moisture-proof bags or drums, with molecular weight, solubility, and WO₃ content (~71.8% calc.) confirmed on the certificate of analysis. Export classification is under HS heading 2841.80 (tungstates).

    Shipping to Japan

    Shipments to Japan are routed from Nhava Sheva or Chennai to Yokohama, Tokyo (Keihin), or Osaka (Hanshin) ports, with sea transit typically 10–14 days — one of the shortest export lanes from India to a major tungsten-consuming market. Tungsten powders and carbides are classified under Japan's Customs Tariff Schedule heading 8101; tungstate chemicals under heading 2841. Export documentation is prepared in English with metric units consistent with JIS/ISO standards used by Japanese buyers. Pricing is quoted in JPY or USD on request.

    Export questions

    Is sodium tungstate supplied in food or pharma grade?

    Our standard sodium tungstate dihydrate is assay min. 99% on an anhydrous basis for industrial applications (pigments, flame retardants, catalysts, corrosion inhibitors). For food- or pharma-grade requirements, share your specification and we will confirm whether it can be met.

    Can you supply WC powder meeting Japanese JIS-aligned specifications?

    Yes — our WC powder (F.S.S.S. 2.5–15.0 µm, total C min. 6.11%, free C max. 0.03%) is documented with metric units and ISO-aligned chemistry on each certificate of analysis, consistent with incoming inspection requirements used by Japanese cemented carbide producers. Please share your grade target and application and we will confirm specification alignment and lead time.
