    Tungsten Oxide (BTO/YTO) — Europe

    European ceramic pigment manufacturers and electrochromic device (ECD) producers — concentrated in Germany and the Netherlands — use blue tungsten oxide (BTO) and yellow tungsten oxide (YTO/WO₃) as precursor compounds for pigment systems and smart-glass coatings respectively. Both oxide forms (~79% W content) are supplied by Jayanth Tungsten as fine calcined powders, with appearance and form confirmed per order on the certificate of analysis. European buyers developing new pigment formulations or electrochromic coatings can request sample lots of BTO or YTO alongside chemistry documentation to support REACH-aligned safety data requirements.

    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 Europe

    Shipments to continental Europe are routed via Nhava Sheva or Mumbai to Rotterdam, Hamburg, or Antwerp, with sea transit typically 3–4 weeks, then onward distribution within the EU customs union. Tungsten powders and compounds fall under EU Combined Nomenclature heading 8101 (powders/carbides) or 2841 (tungstates); chemical products such as sodium tungstate and tungsten oxides are supplied with chemistry data to support REACH documentation. Pricing is quoted in EUR 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.

    Do you provide REACH-relevant documentation for chemical products?

    For sodium tungstate, APT, and tungsten oxide shipments to the EU, we provide chemistry data on the certificate of analysis to support your REACH compliance documentation. Shipments are routed via Rotterdam, Hamburg, or Antwerp with onward EU distribution.
