What Timah Industri does

PT Timah Industri is an Indonesia-based downstream tin manufacturer and a 99.99%-owned subsidiary of PT Timah Tbk, the country's largest tin producer and a member of the state-owned MIND ID mining holding. Founded in 1998 and headquartered in Cilegon, Banten, the company operates two product lines: tin chemicals (BANKASTANNIC SnCl4; BANKASTAB DMTC, MT, TC, TOP and Calcium Zinc stabilizer series) and tin solder (BANKAESA branded bar, wire, powder, shot, and ball/half-ball products in both lead-free and lead-based alloys). Combined nameplate capacity is approximately 24,100 tonnes per annum, with chemical plants in Cilegon (operational since 2011) and a tin solder factory in Cilegon (since 2015) complementing an earlier solder facility on Kundur Island built in 2008. An R&D center equipped with NMR, FTIR, ED XRF, ICP-OES, Rheometer and Extruder supports in-house formulation work and quality control.

The company serves industrial B2B customers across at least 14 end-use verticals — primarily PVC manufacturing (rigid pipes, profiles, roofing), electronics (PCB assembly), automotive electronics, solar panel manufacturing, construction, food packaging, pharmaceutical packaging, glass and coatings, and wire and cable. Its go-to-market is direct enterprise sales, with quote-based pricing, KYC onboarding, and pre-order workflows; the website and WhatsApp are primary contact channels. Geographic reach includes domestic Indonesian manufacturers and exports to Asia, with China explicitly named since 2011.

Revenue is not publicly disclosed. Customers require PVC thermal stabilization, RoHS-compliant lead-free soldering, food-grade and pharmaceutical-grade packaging compliance, and electronics-grade interconnection reliability — all addressed through the company's certified product portfolio. The business holds REACH, BTA, QMS (UKAS-accredited), OHSAS, and EMS certifications, which together form a regulatory gateway to EU and other regulated export markets for specialty tin chemicals.

Core offering

PT Timah Industri manufactures downstream tin products for industrial B2B customers under the BANKASTANNIC, BANKASTAB, and BANKAESA brands. Its two core lines are tin chemicals (stannic chloride, methyltin stabilizers, dimethyltin dichloride, tin one pack, calcium zinc stabilizers) for PVC heat stabilization, glass coating, and catalysis; and tin solder products (lead-free and lead-based in bar, wire, powder, shot, and ball forms) for electronics, automotive, solar panel, and industrial soldering applications. The company operates manufacturing facilities in Cilegon, Banten and Kundur Island, with in-house smelting and an advanced R&D center.

Product overview

PT Timah Industri is a subsidiary of PT Timah Tbk (member of MIND ID - Mining Industry Indonesia), specializing in downstream tin industry with two core product lines: Tin Solder and Tin Chemical products. The company operates under brand names BANKASTANNIC (for SnCl4), BANKASTAB (for stabilizers including DMTC, MT, TC, and TOP series), and BANKAESA (for solder products).
