What Thailand Smelting and Refining does

Thailand Smelting and Refining Co., Ltd. (THAISARCO) is a privately held Thai tin smelter and refiner headquartered in Phuket, founded in 1963 with operations commencing in 1965. The company produces LME-registered tin metal under the THAISARCO brand (minimum 99.9% purity) and PHUKET brand (minimum 99.85% purity), plus high-purity grades up to 5N (99.999%), with current refined metal capacity of 35-40,000 tonnes annually. Downstream operations include tin-lead and lead-free solders (bars, wires, anode balls, powders), tin and tin alloy powders produced via ultrasonic and air atomization, tin shot/granules, pewter, and tin slag by-products.

The company is majority-owned by UK-based Amalgamated Metal Corporation PLC (AMC Group) since 1995, with minority shareholder Escoy Holdings of Malaysia, providing global sourcing reach across Australia, Asia, Africa, Europe, and South America. Revenue is generated through direct B2B sales of refined tin and solder products to electronics OEMs, EMS providers, and solder makers (Sony Technology, Fujikura, Microchip Technology, Celestica, Benchmark Electronics, KCE Group, Nihon Superior, Summit Solders, Electroloy, SVI, Oki, Spansion), plus OEM/white-label subcontract production with Just-In-Time delivery for solder manufacturers in Japan, Malaysia, Singapore, and Europe. The 2008-established THAISARCO Trading division extends the model into ferrous and non-ferrous metals trading for foundry, aerospace, automotive, defense, marine, food processing, and petrochemical customers across Southeast Asia. The company operates ISO 9001, 14001, 45001, and IEC 17025 certified systems and is an RMAP-conformant tin smelter.
