What PT Asahimas Chemical does

PT Asahimas Chemical (ASC) is an Indonesian integrated chemical manufacturer operating a 91-hectare Chlor Alkali–Vinyl Chloride–PVC complex in Cilegon, Banten, with corporate headquarters in Jakarta. Established in 1986 and operational since 1989, ASC is controlled by AGC Inc. (formerly Asahi Glass Company, Japan) with a 52.5% stake; minority shareholders include PT Rodamas (18.0%) and Mitsubishi Corporation (11.5%). The complex applies AGC's proprietary ion-exchange membrane technology for chlor-alkali electrolysis, combined Direct Chlorination and Oxy-Chlorination for EDC/VCM production, and suspension polymerization for PVC resin, yielding nameplate capacities of 700,000 t/yr Caustic Soda, 900,000 t/yr VCM, and 750,000 t/yr PVC. The site additionally houses a captive 2 x 151.5 MW coal-fired power plant and four private ISPS-compliant jetties for bulk distribution.

ASC generates revenue by selling six core products — Caustic Soda (NaOH, 48% solution), Hydrochloric Acid (HCl, 33% solution), Sodium Hypochlorite (NaClO, 10% solution), Ethylene Dichloride (EDC), Vinyl Chloride Monomer (VCM), and Polyvinyl Chloride (PVC) resin in five grades (FJ-57, FJ-60, FJ-65S, FJ-65R, FJ-70) — to domestic Indonesian downstream industries (construction accounts for over 50% of PVC demand, plus pulp and paper, water treatment, textiles, alumina, oil, and food processing) and to export customers across Southeast Asia and Far East Asia. The go-to-market is direct B2B enterprise sales; pricing is not publicly disclosed. ASC holds ISO 9001/14001/45001/50001, SNI, TKDN certificates (75.77%–97.66%), ISCC PLUS, Green Label, and PVC Stewardship Gold from Vinyl Council Australia.

The company employs 1,001–5,000 staff, reports USD 1.6 billion of cumulative investment, and is targeting a 30% Scope 1+2 GHG reduction by 2030 versus a 2019 baseline, with Net-Zero by 2050. Recent strategic activity includes a 10-year ethylene supply agreement with PT Lotte Chemical Indonesia (May 2025), a 15-year Renewable Energy Certificate agreement with PLN (November 2022), and ISCC PLUS certification (July 2025). ASC remains privately held with no public stock listing.
