Tungsten Metal Powder — Japan
Japanese manufacturers of tungsten copper electrical contacts — supplying the domestic high-voltage switchgear, vacuum circuit breaker, and automotive relay sectors — use tungsten metal powder (W ≥ 99.85%, F.S.S.S. 1.5–15 µm) as the dense refractory phase in Cu-W infiltration composites, where tight grain size control and low oxygen content (O max. 0.06%) directly determine arc-erosion resistance and electrical conductivity. Sumitomo Electric Industries and related contact manufacturers qualify incoming W powder to ISO/JIS-aligned chemistry specifications, requiring a full composition table on each certificate of analysis. Jayanth Tungsten's standard grades — 1.5–3, 4–6, 8–10, and 12–15 µm F.S.S.S. with apparent densities 2.5–6.2 g/cc — cover the range specified for Japanese Cu-W contact and radiation shielding applications, with all chemistry documented for incoming-goods qualification.

Applications
Export packaging & documentation
Tungsten metal powder is packed in sealed steel drums under nitrogen or vacuum to prevent oxidation during transit, each lot accompanied by a certificate of analysis stating F.S.S.S. grain size, apparent density, and chemistry (W min. 99.85%, O max. 0.06%). Export classification is under HS heading 8101.94 (tungsten powders).
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
What F.S.S.S. grain sizes are available for export?
Standard grades range from 1.5–3 µm to 12–15 µm F.S.S.S., with corresponding apparent densities from 2.5 to 6.2 g/cc. Custom grain size targets can be agreed for larger export orders — share your application and we will confirm feasibility and lead time.
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.
