Ammonium Paratungstate (APT) — United States
US tungsten powder producers and refiners — particularly those seeking to diversify APT supply away from concentrated single-country sources — use ammonium paratungstate as the crystalline feedstock for in-house calcination to tungsten oxides and hydrogen reduction to metal powder. Jayanth Tungsten's APT (WO₃ min. 88.5%, F.S.S.S. 30–70 µm, −100 mesh standard, carbon max. 0.0010%) is produced from refined and purified tungsten raw materials, with the full chemistry table available per the brochure and certificate of analysis. US buyers evaluating APT for domestic conversion to tungsten metal powder can request sample lots with full documentation to support supply chain 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.
Can you ship to US ports with HTS-ready documentation?
Yes — shipments are exported from Indian ports to Houston, Los Angeles/Long Beach, or New York/New Jersey with commercial invoices referencing the applicable HTS heading (typically 8101 for tungsten metal/carbide powders or 2841 for tungstate chemicals). Certificates of analysis accompany each shipment for CBP and quality records.
