    Tungsten Oxide (BTO/YTO) — Japan

    Japanese electrochromic material researchers, catalyst preparation companies, and ceramic pigment manufacturers use yellow tungsten oxide (YTO/WO₃) as the stoichiometric oxide feedstock for electrochromic device coatings — a technology in which Japanese companies including Asahi Glass (AGC) have been historically active — and as a hydrogen reduction precursor for tungsten metal powder production. Blue tungsten oxide (BTO) serves as the sub-stoichiometric intermediate in tungsten powder production processes. Both forms (~79% W content, fine calcined powder) are supplied by Jayanth Tungsten per order specification, with full composition data on the certificate of analysis for Japanese chemical and materials company incoming qualification.

    Export packaging & documentation

    Blue and yellow tungsten oxides are supplied as fine calcined powders in moisture-proof packaging, with appearance, tungsten content (~79%), and form confirmed on the certificate of analysis. Export classification is under HS heading 2825.90 (tungsten oxides and hydroxides).

    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 is the difference between BTO and YTO for export orders?

    Blue tungsten oxide (BTO) is the sub-stoichiometric reduction intermediate (approx. WO2.72–WO2.9), while yellow tungsten oxide (YTO/WO₃) is the stoichiometric form. Both are supplied per order specification — confirm which form your process requires when requesting a quote.

    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.
