    Tungsten Oxide (BTO/YTO) — Chile

    Tungsten oxide shipments to Chile serve specialty chemical processors and catalyst formulators rather than the mining sector that drives most of the country's tungsten demand. Yellow oxide is the usual specification for these buyers because its defined stoichiometry and storage stability suit catalyst precursor work better than the more reactive blue form. Both grades are supplied at approximately 79% tungsten with purity confirmed against the order specification and stated on the certificate of analysis.

    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 Chile

    Shipments to Chile route from Nhava Sheva or Chennai to San Antonio or Valparaíso, typically 5–6 weeks by sea, usually transhipped via Singapore or Panama. Tungsten powders and compounds are declared under Chilean tariff headings corresponding to HS 8101 and 2841. Pricing is quoted in USD. Chile's low average tariff and extensive free trade agreement network make customs clearance comparatively straightforward, though the SAG and Aduanas documentation set should be confirmed with your customs agent before first shipment.

    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 supply fused tungsten carbide grit to Chilean mining service companies?

    Yes. Chile is one of our mining-driven markets, and hard-facing grit and fused carbide are the products most commonly ordered. Shipments route to San Antonio or Valparaíso in 5–6 weeks with USD pricing and the full documentation set — commercial invoice, packing list, certificate of analysis and certificate of origin.
