🇰🇷 Export to South Korea
Tungsten Oxide (BTO/YTO) — South Korea
South Korean electrochromic material companies, display technology researchers, and catalyst manufacturers — operating within Korea's world-leading electronics and chemical R&D ecosystem — use yellow tungsten oxide (YTO/WO₃) as an active material precursor for electrochromic devices and as a catalyst support, while blue tungsten oxide (BTO) serves as the reduction intermediate in tungsten metal powder production. Both forms (~79% W content, fine calcined powder) are supplied by Jayanth Tungsten per order specification, with complete composition data on the certificate of analysis for Korean chemical and materials company incoming qualification. Sample quantities are available for Korean R&D teams evaluating new electrochromic or catalyst material sources.

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 South Korea
Shipments to South Korea are routed from Nhava Sheva or Chennai to Busan — South Korea's main container port — with sea transit typically 10–14 days. Busan handles the majority of South Korea's industrial imports including metal powders and specialty chemicals. Tungsten powders fall under Korea's Harmonized System heading 8101; tungstate chemicals under HS 2841. Export documentation is prepared in English for Korean Customs Service clearance. Pricing is quoted in USD or KRW 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.
How long does shipping from India to South Korea take?
Sea freight from Nhava Sheva or Chennai to Busan typically takes 10–14 days — one of our shorter export lanes. All shipments are accompanied by a certificate of analysis and packing list prepared for Korean Customs Service clearance under HS 8101 (tungsten powders/carbides) or HS 2841 (tungstates).
