Basic Iron and Steel Manufacturing Industry in Indonesia
KBLI 2410 — Krakatau heritage flat, Gunung Raja Paksi long products, and the Tsingshan-led nickel-pig-iron and stainless wave
Indonesia's basic iron and steel industry is structured around three pillars. First, heritage flat steel anchored by PT Krakatau Steel (IDX: KRAS, state-owned BUMN at Cilegon) plus PT Krakatau Posco joint venture (with POSCO Korea) producing slab, hot-rolled coil (HRC), cold-rolled coil (CRC) and coated steel. Second, long products and merchant steel led by PT Gunung Raja Paksi (IDX: GGRP, the Sinarindo Gunung Raja Paksi group) at Bekasi/Cikarang, plus PT Ispat Indo (now part of ArcelorMittal subsidiaries network), PT Master Steel (Master Steel Group), PT The Master Steel Manufactory, PT Hanil Jaya Steel, PT Krakatau Wajatama, PT Jakarta Cakratunggal Steel Mills. Third, the rapidly grown nickel-pig-iron (NPI) and stainless-steel value chain built by Tsingshan Holding Group and Delong (China) at Indonesia Morowali Industrial Park (IMIP, Sulawesi Tengah) and Indonesia Weda Bay Industrial Park (IWIP, Halmahera Tengah), making Indonesia a global stainless-steel and nickel-intermediate producer.
PT Krakatau Steel (IDX: KRAS) — state-owned BUMN at Cilegon; flat-steel heritage; restructuring under Pupuk Indonesia-style operational reset
Krakatau Posco (KS-POSCO JV) — slab and hot-rolled coil at Cilegon; integrated blast furnace
Gunung Raja Paksi (IDX: GGRP) — long products, sections, rebar, wire rod at Bekasi/Cikarang
Tsingshan Holding Group + Delong nickel-pig-iron and stainless at IMIP (Morowali) and IWIP (Weda Bay)
Other EAF mini-mills and long-products: Master Steel, Ispat Indo, Hanil Jaya Steel, Krakatau Wajatama, Jakarta Cakratunggal Steel Mills
Indonesia is structurally a net importer of HRC and specialty steel but net-exporter of stainless steel and nickel intermediates
Executive Summary
Indonesia's basic iron and steel industry (KBLI 2410) is built on three pillars. First, the heritage state-owned flat-steel anchor PT Krakatau Steel (IDX: KRAS) at Cilegon (Banten) — making slab, HRC, CRC, coated steel — together with PT Krakatau Posco joint venture (Krakatau Steel + POSCO Korea) operating an integrated blast-furnace and converter complex on the Cilegon site (slab and HRC). Krakatau Steel underwent major debt restructuring (mid-2020s) and ongoing operational reset under Kementerian BUMN.
Second, the long-products and merchant-steel segment led by PT Gunung Raja Paksi (IDX: GGRP, Sinarindo Gunung Raja Paksi group) at Bekasi/Cikarang producing structural sections, rebar, wire rod, plates, and engineering steel; plus PT Master Steel (Master Steel Group), PT Ispat Indo (ArcelorMittal affiliated), PT Hanil Jaya Steel, PT Krakatau Wajatama, PT Jakarta Cakratunggal Steel Mills, PT The Master Steel Manufactory, PT Inti General Yaja Steel. Most operate via electric arc furnace (EAF) using scrap and/or DRI/HBI.
Third, the dramatically scaled nickel-pig-iron (NPI) and stainless-steel value chain built by Tsingshan Holding Group (China) and partners (Delong, Eternal Tsingshan, Brunp, Indofood-affiliated CMOC partnerships, MIND ID) at IMIP (Indonesia Morowali Industrial Park, Sulawesi Tengah) and IWIP (Indonesia Weda Bay Industrial Park, Halmahera Tengah). These complexes integrate nickel ore mining (under MIND ID's Antam and private miners), rotary kiln electric furnace (RKEF) for NPI, stainless-steel making, and now also EV battery-precursor chemistry. Indonesia is structurally a net importer of HRC and specialty steel for automotive and machinery, but a net-exporter of stainless steel and nickel intermediates.
Krakatau Steel (KRAS) is sole BUMN flat-steel heritage anchor; restructured mid-2020s
Krakatau Posco JV operates integrated BF-BOF slab and HRC at Cilegon
Gunung Raja Paksi (GGRP) leads long products and merchant steel via EAF
Other EAF mini-mills: Master Steel, Ispat Indo, Hanil Jaya, Krakatau Wajatama, Jakarta Cakratunggal Steel Mills
Tsingshan + Delong built world-scale NPI and stainless capacity at IMIP and IWIP
Indonesia is net importer of HRC/specialty; net exporter of stainless and nickel intermediates
Regulation: Kemenperin (SNI mandatory), KLHK environmental, ESDM nickel ore export ban
Why this industry matters in Indonesia
Steel underpins construction, automotive, shipbuilding, energy infrastructure, machinery — strategic basic-industry status.
Nickel ore export ban (since 2014, reinstated 2020) drove the world-scale NPI and stainless industry at IMIP/IWIP, lifting Indonesia to leading global stainless exporter.
Krakatau Steel restructuring affects BUMN balance sheet and Cilegon industrial cluster employment.
Steel is energy- and emissions-intensive; decarbonisation pressure (green steel, DRI, hydrogen) emerging.
So what: Practical implications
Operators: Maintain integrated BF-BOF efficiency (Krakatau Posco); modernise EAF; secure scrap and DRI/HBI supply; explore green-steel pathways
Buyers (construction, automotive, machinery): Diversify between domestic flat steel, long-products, imports (Vietnam, Korea, China, Japan)
Investors: Tsingshan/IMIP/IWIP stainless and EV-battery integration; Krakatau Steel turnaround; Gunung Raja Paksi (GGRP) growth
Policymakers: TKDN steel rules, anti-dumping enforcement, decarbonisation roadmap, nickel ore policy
Indonesia at a Glance
Republic of Indonesia: crude-steel capacity quintupled by nickel/stainless cluster wave
Indonesia's crude-steel capacity has grown dramatically since 2018 driven by Tsingshan-led NPI and stainless additions at IMIP (Morowali, Sulawesi Tengah) and IWIP (Weda Bay, Halmahera Tengah). Total crude-steel capacity is now in the tens of millions of tonnes annually, placing Indonesia among the top global producers by capacity.
Heritage flat steel: Krakatau Steel + Krakatau Posco at Cilegon. Long products and merchant: Bekasi/Cikarang cluster (Gunung Raja Paksi, Master Steel, Ispat Indo, Hanil Jaya, Krakatau Wajatama, Jakarta Cakratunggal Steel Mills). Stainless and nickel intermediates: IMIP + IWIP.
Apparent steel demand runs in the multi-tens-of-millions-of-tonnes range driven by construction (Jakarta MRT extension, IKN Nusantara new capital, toll roads, ports, housing), infrastructure, automotive (Astra-Toyota, Daihatsu, Mitsubishi, Hyundai BEV plant), shipbuilding (PAL, BBI, Daya Radar), energy (PLN, Pertamina pipelines).
Import dependence remains high for automotive-grade HRC, electrical steel, tinplate, and specialty grades — sourced from Vietnam (Formosa Ha Tinh), Korea (POSCO), Japan (Nippon Steel, JFE), China.
Hyperlocalisation is key to navigate Indonesia's market
Cluster geography is sharp. Cilegon (Banten) is the BUMN flat-steel anchor; Bekasi/Cikarang/Karawang is the long-products and downstream-fabrication corridor; Morowali (Sulawesi Tengah) and Weda Bay (Halmahera Tengah) host the Tsingshan/Delong/MIND ID-backed nickel-stainless clusters; Gresik/Surabaya (East Java) hosts older long-products and ship-plate producers including ArcelorMittal-affiliated and PT Bhirawa Steel.
TKDN (Tingkat Komponen Dalam Negeri — local content) policy under Kemenperin reserves government and BUMN procurement for SNI-certified domestic steel, supporting Krakatau and Gunung Raja Paksi.
Opportunities extend beyond cities
IMIP (Morowali, Sulawesi Tengah) and IWIP (Weda Bay, Halmahera Tengah) — under Bintang Delapan / Tsingshan and Tsingshan / Eternal Tsingshan / IWIP partnership respectively — house RKEF, NPI smelting, stainless steel, and increasingly EV-battery precursor (HPAL high-pressure acid leach) facilities, integrated with captive coal-fired power plants and dedicated ports.
Pomalaa (Sulawesi Tenggara), Konawe (Antam), and Sangihe Talaud (Antam) are emerging nickel-stainless adjacent investments. PT MIND ID (BUMN mining holding) increasingly anchors downstream integration via Antam.
IMIP and IWIP NPI/stainless capacity expansion under Tsingshan/Delong
EV-battery precursor (HPAL nickel intermediates) build-out at IMIP/IWIP
Krakatau Steel operational reset and Krakatau Posco modernisation
Long-products demand from IKN Nusantara, MRT, toll roads, housing
Automotive HRC import substitution pressure (Hyundai BEV, Toyota hybrid)
Green-steel pathway (hydrogen DRI, HBI, scrap-based EAF) emerging
Distribution realities: cluster logistics, dedicated ports, intra-Indonesia shipping
Distribution: dedicated ports (IMIP's Bungku port, IWIP port at Weda Bay, Krakatau Bandar Samudera/KBS port at Cilegon, Tanjung Priok and Tanjung Perak general), intra-Indonesia bulk shipping, rail (Krakatau Bandar Samudera-Krakatau Posco), truck and rail to downstream fabricators in Cikarang/Bekasi corridor.
Inputs: iron ore (mostly imported — Brazil, Australia), nickel ore (domestic Morowali, Halmahera, Pomalaa, Konawe), scrap (imported and domestic), coal (domestic for captive power), natural gas (Pertamina, PHE).
Cluster integration with dedicated ports lowers logistics cost
Iron-ore import dependence ties Krakatau cost to global ore + freight
Nickel ore policy directly anchors Tsingshan/Delong investment
Scrap availability shapes EAF mini-mill economics

Policy
Impact and Sustainability
Impact runs through trade balance, employment in cluster towns, emissions and tailings/effluent management.
Trade balance and downstream value capture
Nickel ore ban moved value capture downstream — stainless and EV-precursor exports replace ore exports.
Export revenue vs upstream miner livelihoods
Downstream value vs Chinese-dominant ownership
Employment in cluster towns (Morowali, Weda Bay)
IMIP and IWIP employ tens of thousands; major economic transformation but social tension over Chinese worker share, safety incidents.
Job creation vs labour relations
Local development vs migrant influx
Emissions and decarbonisation
Captive coal-fired power at IMIP/IWIP and BF-BOF at Krakatau Posco are high-emission; CBAM (EU Carbon Border Adjustment) and global decarbonisation pressure mount.
Cost competitiveness vs decarbonisation
Coal-fired captive vs renewables/hydrogen
Tailings, effluent and environmental risk
HPAL produces tailings; deep-sea tailings disposal (DSTD) considered; KLHK environmental scrutiny increasing.
Capex of dry stack vs DSTD
Project viability vs environmental risk

How value flows across the ecosystem
Iron ore (mostly imported) and coking coal → Krakatau Posco BF-BOF; scrap and DRI/HBI → EAF mini-mills (Gunung Raja Paksi etc.); nickel ore (domestic) → RKEF NPI → stainless meltshop (Tsingshan); HPAL nickel intermediate → EV-battery precursor. Steel products → service centres → fabricators → construction/automotive/shipbuilding/energy customers.
Strategic chokepoints sit at iron-ore import logistics, nickel ore allocation, Krakatau Steel/Posco BF-BOF utilisation, TKDN/SNI gating, and HPAL technology/tailings.

FAQs & Sources
FAQs
Who leads Indonesia's iron and steel industry?
Flat: PT Krakatau Steel (IDX: KRAS, BUMN) + PT Krakatau Posco joint venture (with POSCO Korea) at Cilegon. Long-products: PT Gunung Raja Paksi (IDX: GGRP, Sinarindo group) plus PT Master Steel, PT Ispat Indo (ArcelorMittal), PT Hanil Jaya, PT Krakatau Wajatama, PT Jakarta Cakratunggal Steel Mills. Stainless/NPI: Tsingshan Holding Group + Delong + Eternal Tsingshan at IMIP (Morowali) and IWIP (Weda Bay).
What drove the nickel-stainless cluster wave?
Indonesia's nickel ore export ban (first imposed 2014, partially relaxed 2017, fully reinstated 2020) forced downstream onshore investment. Tsingshan led with IMIP from 2015; Delong/Eternal followed; IWIP scaled in 2020s. HPAL nickel-intermediate plants follow for EV-battery precursor.
Who leads HPAL for EV-battery precursor?
Halmahera Persada Lygend (HPL — Lygend/Harita Group at Obi Island), QMB New Energy Materials (Tsingshan-CATL-CMOC at IMIP), Huayou-led HPAL, Sumitomo-led Pomalaa (Pomalaa nickel project).
How concentrated is the industry?
Moderately to highly concentrated by segment. Flat-steel: Krakatau Steel + Posco duopoly. Long-products: Gunung Raja Paksi leads with 5–7 EAF mini-mills. Stainless/NPI: Tsingshan and Delong dominate. HPAL: emerging multi-player oligopoly.
Is Indonesia a net steel exporter?
Net exporter of stainless steel and nickel intermediates. Net importer of automotive-grade HRC, electrical steel, tinplate, specialty grades — sourced from Vietnam (Formosa), Korea (POSCO), Japan (Nippon Steel, JFE), China.
What about decarbonisation?
Steel is energy- and emissions-intensive. Krakatau Posco BF-BOF and IMIP/IWIP captive coal face decarbonisation pressure including EU CBAM (Carbon Border Adjustment Mechanism). Green-steel pathways (hydrogen DRI, scrap-based EAF, CCS) emerging but capital-intensive.
