    Ammonium Paratungstate (APT) — Spain

    Spanish specialty chemical importers and advanced materials processors — operating within Barcelona's chemical industry cluster and the Basque Country's materials science sector — source ammonium paratungstate (APT, WO₃ min. 88.5%, carbon max. 0.0010%, F.S.S.S. 30–70 µm) as the crystalline tungsten intermediate for tungsten oxide and metal powder production, or for catalyst applications in Spain's large petroleum refining sector (Repsol, Cepsa refineries in Tarragona, Algeciras, and Cartagena). Spain's oil refining capacity of approximately 70 million tonnes/year makes it a significant user of HDS catalyst systems, where tungsten-containing W-Ni/W-Co catalyst precursors are produced from APT. Jayanth Tungsten's APT is supplied with full ICP chemistry CoA and EU CN 2841 documentation, with REACH-compliant SDS for Spanish import qualification.

    Export questions

    What chemistry data is provided with APT shipments?

    Each lot's certificate of analysis states WO₃ content (min. 88.5%), carbon (max. 0.0010%), apparent density, and F.S.S.S. grain size, with the full impurity composition table as set out in our brochure available on request.

    Do you supply tungsten carbide powder to Spanish cemented carbide and tooling manufacturers?

    Yes. Jayanth Tungsten exports WC powder (F.S.S.S. 2.5–15 µm, total C min. 6.11%) and W metal powder to Spain via Valencia, Barcelona, or Bilbao under EU CN 2849/8101. ISO 9001:2015 CoA, REACH-compliant SDS, and EU Combined Nomenclature documentation are provided with every shipment. Transit 3–4 weeks from Nhava Sheva.
