Buying Steel Structures from China for Indonesia
Indonesia offers Chinese fabricators the shortest sea route in the region, but it pairs that advantage with a specific compliance stack: SNI 1729 and SNI 7860 design requirements, BMKG seismic hazard review, welding certification, and an API-number import licence. This guide explains what to specify, what approvals the import chain needs, and a realistic cost and lead-time picture — including the 9,000 t project we have already delivered at Jinrui New Energy Coke.
Which Indonesian Codes Your Fabricator Must Meet
Indonesian steel construction references national standards with clear seismic content. If your technical specification does not name them, many foreign fabricators will default to their domestic codes. Put the documents below in writing before quoting — they govern weld acceptance, seismic detailing and coating on site.
| Document | Scope | Key Requirement for Imported Steel |
|---|---|---|
| SNI 1729 | Design of steel structures (LRFD) | Member, connection and stability design per the Indonesian national standard, reviewed by the project's local design consultant. |
| SNI 7860 | Seismic provisions for steel structures | Seismic design categories follow BMKG hazard maps; detailing, brace types and connection ductility must satisfy SNI 7860. |
| AWS D1.1 / ISO 3834 | Structural welding quality | Welders qualified to AWS D1.1 with certificates acceptable to the Indonesian welding profession (e.g. IWS); WPS/PQR documented per joint type. |
| ASTM A572 / EN 10025 equivalents | Structural steel material grades | Mill certificates per heat with chemistry and tensile values. Q355B maps to A572 Gr.50 with documented chemistry for consultant review. |
| ISO 12944 | Corrosion protection of steel structures | Tropical humidity and coastal salt call for C4-class systems; hot-dip galvanizing or zinc-rich paint with specified DFT. |
How We Execute Indonesia-Code Projects
On Indonesia-bound orders we design and detail to SNI 1729, with seismic provisions checked against SNI 7860 and BMKG hazard data supplied by the client's engineer. Welding follows AWS D1.1 with WPS qualified in our Xuzhou shop; coating is quoted to ISO 12944 C4 for coastal sites, with DFT records per member. Shop drawings are issued for the local design consultant's review, and independent witness inspection (SGS or Bureau Veritas) is available before loading.
Our record in Indonesia includes the Jinrui New Energy Coke plant — roughly 9,000 t of fabricated steel — which means we already hold the export documentation patterns, packing practices and site-delivery experience that Indonesian customs and contractors expect.
Roof Systems for Every Building Type
From portal frames for factories to space grids and pipe trusses for wide-span halls, we fabricate the roof system your project brief specifies — all under one quality system.
Indonesia-Specific Requirements to Plan Around
Indonesia combines import licensing with seismic regulation. Neither is difficult, but both need to be in the programme from day one rather than discovered at the port.
Import Licensing
Importers must hold an API number (Angka Pengenal Importir) issued by the Ministry of Trade — API-U for general importers or API-P for producers importing for their own use — and the import declaration (PIB) is filed with customs (DJBC) under the CEISA system. On DDP terms we coordinate through local customs brokers who hold the licences, so the buyer needs only their own API-P where the goods arrive for use in their own facility. The China–ASEAN Free Trade Agreement (ACFTA) Form E certificate of origin can reduce or remove duty on eligible steel articles — ask us for the document set to qualify.
Seismic & Construction Review
Because most of Indonesia sits in active seismic zones, the design must be verified against BMKG seismic hazard maps with the correct design category per SNI. Site welding and erection are typically supervised by a licensed local contractor, and welder certificates are checked against Indonesian practice — have the original certificates, not summaries, shipped with the documentation file. ISO 12944 C4 corrosion protection matters here as much as structure: humidity and marine salt reach even inland industrial zones during the wet season.
Allow for local contractor licensing (IUJK) requirements on site work — imported steel is your asset, but erection labour and its permits are normally the contractor's scope. Freeze the erection method statement early; it drives fit-up and lift planning in the drawings.
Import Duty, PPN and What You Will Actually Pay
Imports into Indonesia attract customs duty (BTKI tariff schedule), PPN VAT and usually PPh 22 import income tax. Rates depend on the HS classification of the goods — fabricated structures commonly fall in HS 7308 — so confirm the classification and current rates with your customs broker at import time. The figures below are planning guidance, not a binding quote.
| Cost Component | Indicative Magnitude | Notes |
|---|---|---|
| Import duty, steel structures | 0–10% by HS code (BTKI schedule) | ACFTA Form E may reduce eligible articles toward 0%; confirm at import. |
| VAT (PPN) on import | 11% (rate since April 2022; check current) | Levied on CIF plus duty; recoverable for PKP-registered businesses. |
| Import income tax (PPh 22) | 2.5% typical for API holders | Prepaid income tax at clearance; non-API importers pay a higher rate. |
| Ocean freight, Shanghai→Jakarta | USD 25–40 / t (2026 indicative) | Only 4–6 days sailing; Tanjung Perak (Surabaya) runs 6–8 days. |
| Port handling & clearance | Per container / per tonne | Tanjung Priok dwell depends on document completeness — file the PIB ahead of arrival. |
The bottom line: with duty typically single-digit (sometimes zero under ACFTA) plus 11% PPN and 2.5% PPh 22, the landed cost premium over FOB stays modest — and with only 4–6 days of sea time from Shanghai, inventory in transit is small. Total landed cost = FOB + freight + duty + PPN + PPh 22 + clearance. Compare on a CIF or DDP basis, not FOB.
We quote FOB and CIF by default and DDP on many Indonesia routes through our logistics partners, so you see one landed price. Send the drawings and destination port and we will return a duty-optimised breakdown your customs broker can verify line by line.
Timeline to Your Indonesian Site, Step by Step
Indonesia has the shortest sea leg from China in this region — the critical path is fabrication and documentation, not transit. Build the milestones below into the contract so approvals and payments stay anchored.
Shop Drawing & Approval — Wk 0-3
We issue Tekla shop drawings and erection plans with seismic detailing notes for the local design consultant. Budget 2–3 weeks for standard portal frames; 4–5 for complex grids or braced frames.
Material Procurement & Mill Certs — Wk 2-5
ASTM A572 or EN 10025 equivalents ordered per heat; mill certificates checked before cutting. Q355B is mapped to A572 Gr.50 with documented chemistry.
Fabrication & QC — Wk 5-12
A 1,000 t factory frame runs 6–9 weeks in our shop. Fit-up to AISC tolerances, 100% weld inspection by certified QC, seismic connection detailing, then ISO 12944 C4 coating with DFT records.
Pre-Shipment Inspection & Loading — Wk 11-13
Optional third-party witness (SGS/BV). Timber packing is ISPM-15 fumigated and stamped; steel bundles strapped and edge-protected; documents prepared for PIB filing.
Ocean Transit — Wk 13-14
Shanghai to Tanjung Priok (Jakarta) is 4–6 days sailing — the shortest in this region — and 6–8 days to Tanjung Perak (Surabaya). Add 2–5 days port dwell.
Customs Clearance & Delivery — Wk 14-16
PIB declaration with API number, duty plus PPN and PPh 22 settled at clearance. DDP is available on many Indonesia routes — one invoice, no surprises at the gate.
Delivered in Indonesia, Proven at Scale
Our Indonesian delivery record is not an abstraction — the Jinrui New Energy Coke project puts roughly 9,000 t of fabricated steel into a local plant. Around it, the projects below show the energy-sector and large-roof capability Indonesian buyers typically evaluate.
Jinrui New Energy Coke, Indonesia
Roughly 9,000 t of fabricated steel shipped into Indonesia for a new energy coke plant — local evidence of our import documentation, packing, transit and delivery chain working end to end.
229 m Coal Shed, Guodian Ningxia
The longest prestressed beam-string coal shed by span — extreme wind and deflection controls and EPC delivery discipline, directly relevant to Indonesian power and energy projects.
Large-Roof Programme Capacity
Space grids and pipe trusses for wide-span halls across 40+ countries — the same roof systems, QC and erection documentation catalogue Indonesian projects draw on.
Indonesia Buyer Questions, Answered
Do you design to SNI 1729 and SNI 7860?
Yes. We design and detail to SNI 1729 with seismic provisions checked against SNI 7860 using BMKG hazard data supplied by the client's engineer. Shop drawings go to your local design consultant for review before fabrication.
What import documents does the buyer need?
An API number (import licence), the PIB declaration and payment of duty, PPN and PPh 22. We supply packing lists, invoices, mill certificates, weld records and, where eligible, the ACFTA Form E certificate of origin to lower the duty line.
How long does shipping from China actually take?
Shanghai to Tanjung Priok is 4–6 days sailing — the shortest sea leg from China in this region. Plan 14–16 weeks total from approved drawings to site on a standard 1,000 t programme.
What payment terms do you accept?
30% deposit, 60% against bill of lading, 10% after arrival survey — or LC at sight for larger and public-sector projects. DDP quotes are available on many Indonesia routes.
