A China+1 strategy does not require a company to replicate its operations in China in Indonesia. For many manufacturers, the stronger model is to retain production stages that depend on China’s established supplier, engineering, and technical capabilities while moving activities to Indonesia where local inputs, production economics, or access to Indonesian and ASEAN markets create a stronger commercial case.
Where Should the China–Indonesia Production Split Occur?
The strongest China+1 structure does not necessarily move complete product lines. It can divide production according to where individual processes have the strongest supplier, technical, resource, and market rationale.
Keep Supplier- and Engineering-Dependent Production in China
Activities that depend heavily on China’s existing industrial ecosystem have a stronger case for remaining there. A Chinese facility may operate within established networks of component manufacturers, tooling companies, maintenance providers, and specialist subcontractors. Moving one production stage to Indonesia can reduce its direct manufacturing cost while increasing procurement, freight, inventory, and coordination costs if most critical inputs still originate in China.

Technically complex manufacturing can face the same constraint. Precision processes, specialized machinery, rapid tooling changes, and production requiring frequent interaction between engineers and suppliers can be expensive to separate from an established Chinese operation. Research and development, product engineering, and supplier management can also remain in China while selected manufacturing capacity moves.
Production principally serving Chinese customers has less reason to relocate. Manufacturing those products in Indonesia and shipping them back to China adds another international movement of goods, with additional freight, customs procedures, inventory, and lead times.
Move Resource-Linked and Separable Production to Indonesia
Indonesia becomes more relevant where production stages can operate without those dependencies. Labor-intensive manufacturing, assembly, finishing, testing, and packaging can move when the processes are sufficiently standardized, and intermediate goods can be transported economically from China.
The case becomes stronger when production is tied directly to Indonesian resources. Downstream industries attracted IDR 300.1 trillion (USD 18.5 billion) in investment during H1 2026, equivalent to 29.7% of Indonesia’s total investment realization. Mineral downstream investment was concentrated in commodities including bauxite, nickel, copper, iron and steel, and silica sand.
Chinese companies are already applying this model. Zhejiang Huayou Cobalt is participating in the Pomalaa project in Southeast Sulawesi with PT Vale Indonesia and Ford. The project combines local nickel mining with high-pressure acid leach (HPAL) processing to produce mixed hydroxide precipitate (MHP), an intermediate material used in electric-vehicle batteries.
The HPAL project is being developed through PT Kolaka Nickel Indonesia, a joint venture involving Vale, Huayou, and Ford. It is designed for an annual output of 120,000 tonnes of nickel and 15,000 tonnes of cobalt contained in MHP, while investment in the Pomalaa mine and HPAL facilities reaches USD 4.5 billion. Vale reports project progress through June 2026, confirming that the development remains active.
The Pomalaa project demonstrates why some activities have a stronger case for moving to Indonesia than others. Huayou brings established battery-material processing capabilities, while the Indonesian operation places resource-dependent processing alongside Indonesia’s nickel supply. The rationale is not to reproduce the company’s Chinese industrial footprint, but to locate a specific part of the value chain where the relevant resource is available.
Test the Economics of the Production Handover
Shipping compact, high-value components from China for assembly in Indonesia creates a different cost structure from transporting bulky, low-value intermediate products whose freight costs absorb much of the production saving.
Capital expenditure creates another dividing line. Moving a standardized assembly process requiring limited equipment is different from duplicating an automated production line containing specialized machinery already operating in China. In the latter case, the Indonesian operation must generate enough additional margin, capacity, or risk reduction to justify maintaining production assets in both countries.
Inventory requirements also increase when the production chain crosses a national border. An Indonesian facility dependent on Chinese components may need additional inventory to cover shipping and customs lead times, tying more working capital to the production cycle.

Processes requiring frequent adjustments between component suppliers, engineers, and production teams are also harder to separate across China and Indonesia. Stable downstream processes with fixed specifications are easier to transfer without reproducing the engineering capability supporting the Chinese operation.
Account for ACFTA Tariffs and Rules of Origin
Indonesia and China trade preferentially through the ASEAN–China Free Trade Area (ACFTA), rather than through a standalone bilateral Indonesia–China FTA. Both countries also participate in RCEP.
ACFTA can materially affect the economics of a production chain divided between China and Indonesia. Indonesia’s Ministry of Trade states that tariffs have been eliminated on 94.6% of tariff lines for Indonesian-origin exports to China. The agreement also provides for regional cumulation, allowing qualifying originating materials from ACFTA members to contribute toward the origin of a finished product manufactured in another member country.
The origin rules are particularly relevant when a manufacturer retains component production in China but performs additional manufacturing in Indonesia. Under the ACFTA origin framework, the general 40% ACFTA-content calculation requires non-ACFTA and undetermined-origin materials to account for less than 60% of the finished product’s FOB value. ACFTA also provides for cumulation where the aggregate ACFTA content of the final product is at least 40%. Product-specific rules can impose different origin criteria.
For example, Indonesia’s Ministry of Trade identifies 40% regional value content or a change in tariff subheading among the ACFTA origin criteria applicable to certain iron and steel products under HS Chapters 72 and 73.
A manufacturer retaining Chinese components while moving downstream production to Indonesia needs to map the finished product’s HS classification, applicable product-specific rule, value added in each country, and origin of its inputs. The amount and type of processing performed in Indonesia can affect whether the finished product qualifies for preferential treatment.
Does the China–Indonesia Split Actually Reduce Cost and Dependency?
The financial comparison changes once the Chinese and Indonesian facilities are treated as one production system.
Suppose a product currently costs USD 100 per unit to manufacture entirely in China. Moving final assembly to Indonesia reduces direct production costs by an illustrative USD 8 per unit. If China–Indonesia freight adds USD 3, additional inventory carrying costs add USD 2, and duplicated quality-control and administrative costs add USD 1, the effective saving is only USD 2 per unit.
Production volume can determine whether that saving is sufficient. If establishing and operating the additional Indonesian capacity creates USD 1 million in fixed costs, a USD 2 unit saving requires 500,000 units to recover that amount through unit-level savings. These figures are illustrative, but they show why direct factory-cost comparisons can materially overstate the financial benefit of moving production.

The same calculation applies to supply-chain dependency. Moving 50% of final production volume to Indonesia does not mean China exposure has fallen by 50%. If the Indonesian plant still sources 70% of its input value from China, depends on Chinese technicians for critical machinery, and relies on the Chinese operation for production knowledge, disruption in China can still interrupt Indonesian output.
Reducing that dependency can involve qualifying Indonesian alternatives for selected inputs while retaining Chinese sourcing where specialist components cannot be replaced economically. The resulting supply chain can remain deliberately integrated across both countries rather than attempting to eliminate Chinese inputs.
