Karawang EV Battery Industry: MRO and Supply Chain Guide
Karawang is now home to operating battery-cell manufacturing capacity serving electric vehicles and energy-storage applications. For surrounding manufacturers and suppliers, the opportunity is real—but so are the requirements for technical specification, contamination control, electrical safety, chemical handling, traceability and dependable MRO support.
Karawang now has two operating battery-cell manufacturing facilities
The EV battery story in Karawang has moved beyond plans, groundbreaking ceremonies and investment announcements.
PT HLI Green Power, a joint venture associated with Hyundai Motor Group and LG Energy Solution, has operated its battery-cell facility in Karawang since 2024. The facility has an annual capacity of approximately 10 GWh.
A second major facility has now entered operation. PT Contemporary Amperex Technology Indonesia Battery, or CATIB, began operating in July 2026 with an initial cell-production capacity of 6.9 GWh per year. Its output is intended for both electric vehicles and battery energy storage systems.
This makes Karawang increasingly important in Indonesia's battery manufacturing chain. It does not, however, mean that every industrial supplier in West Java automatically becomes part of an EV battery supply chain.
Battery manufacturing introduces demanding requirements around product specification, contamination control, safety, traceability, process stability and qualification. A supplier must first understand the actual requirement it is being asked to support.

The ecosystem is growing—but each project is at a different stage
| Facility / development | Current status | Important distinction |
|---|---|---|
| HLI Green Power — Karawang | Operating since 2024 with approximately 10 GWh annual battery-cell production capacity. | This is established operating capacity, not a future announcement. |
| CATIB — Karawang | Operating since July 2026 with initial annual capacity of 6.9 GWh. | Produces cells for EV and BESS applications. |
| CATIB expansion | Expansion toward total capacity of around 15 GWh has been discussed and remains subject to further development. | Do not describe 15 GWh as current operating capacity. |
| Integrated ANTAM–IBC–CBL ecosystem | Broader upstream and downstream facilities include nickel processing, precursor/cathode materials, cells and recycling plans. | Different facilities have different schedules, locations and commissioning status. |
| West Java EV manufacturing | Battery manufacturing is developing alongside wider EV assembly and supplier investment in Karawang and Subang. | EV manufacturing and battery manufacturing are related but operationally distinct industries. |
A battery ecosystem contains very different industrial processes
The phrase “EV battery supply chain” can cover mining, refining, precursor production, cathode and anode materials, cell manufacturing, module and pack assembly, battery management electronics, vehicle integration, logistics, recycling and stationary energy storage.
Each stage requires different materials, equipment, safety controls and maintenance support.
A company supplying bearings to a conveyor system, for example, is participating in a very different requirement from a company supplying electrolyte or cathode material directly into cell production.
For procurement, the distinction between direct production material and indirect MRO material is therefore essential.
Battery production creates MRO demand—but there is no universal EV shopping list
The fastest-moving maintenance item in one battery plant may be irrelevant to another because equipment manufacturers, process design, installed base and maintenance strategy differ.
Mechanical maintenance
Bearings, belts, seals, fasteners, pneumatic components and other replacement items may support conveyors, pumps, mixers and production machinery.
Electrical & controls
Sensors, relays, control devices, motors and electrical components must match the installed equipment and approved specification.
Facility systems
HVAC, compressed air, utilities, pumps, filtration and environmental-control systems require routine maintenance support.
Tools & instruments
Torque tools, meters, test equipment and maintenance tools should be selected against the specific task and accuracy requirement.
Safety supplies
PPE and emergency equipment must follow hazard assessment rather than a generic “battery industry PPE package.”
Cleaning & contamination control
Cleaning materials, wipes, filters and handling products can be process-sensitive and require controlled specification.
Battery manufacturing combines several hazard classes
The original article treated battery safety as though the industry simply requires “more advanced PPE.” That is too broad.
Different areas of a battery facility can involve chemical exposure, combustible materials, electrical energy, moving machinery, manual handling, hot surfaces, stored energy, clean-process requirements and fire risk.
| Hazard area | Examples | Control approach |
|---|---|---|
| Chemical | Electrolytes, solvents, cleaning chemicals and process chemicals. | SDS review, compatible storage, ventilation, closed transfer, PPE and spill-response procedures as applicable. |
| Electrical | Energized equipment, test stations, modules, packs and energy-storage systems. | Isolation, qualified work procedures, appropriate PPE, protection and verification of electrical condition. |
| Mechanical | Conveyors, presses, winding equipment, lifting systems and automated machinery. | Machine guarding, interlocks, isolation, lifting controls and maintenance procedures. |
| Thermal / fire | Abnormal battery conditions, ignition sources and combustible process materials. | Risk-specific detection, suppression, segregation and emergency planning. |
| Ergonomic / handling | Heavy modules, repetitive assembly and manual movement. | Material-handling aids and workstation design based on actual loads. |
| Contamination | Particles, moisture and incompatible materials entering controlled processes. | Controlled environments, housekeeping, approved materials and process discipline. |
For PPE and industrial safety sourcing requirements, see our Karawang Safety Tool Supplier page.
ESD control is relevant where sensitive electronics require it—not everywhere
Battery manufacturing frequently includes electronics such as battery-management systems, sensing circuits, communication modules and other electrostatic-discharge-sensitive components.
Those operations may require a formal ESD control program with qualified worksurfaces, personnel grounding, suitable tools, packaging, ionization and verification.
However, it is incorrect to assume that every mechanical operation, cell container or battery component automatically requires the same ESD controls.
ESD control must also remain separate from electrical-shock protection. Conductive or dissipative ESD equipment should never be assumed to provide insulation against hazardous voltage.
For a more detailed treatment, see our guide to ESD-safe tooling for battery and electronics assembly.
“Battery chemical” is not a usable purchase specification
Battery manufacturing can involve specialised active materials, salts, solvents, binders, cleaning agents and other chemicals. Their hazards and compatibility differ significantly.
A procurement request should therefore identify the exact chemical, grade, concentration, purity and applicable manufacturer specification rather than using broad descriptions such as “battery solvent” or “lithium chemical.”
| Procurement information | Why it matters |
|---|---|
| Chemical identity | Exact substance or commercial formulation avoids dangerous substitution based on a generic product category. |
| Grade / purity | Process-critical applications may require limits that ordinary industrial-grade material cannot meet. |
| Manufacturer / approved source | Customer or process qualification may restrict substitutions. |
| SDS | Provides hazard classification, handling, exposure-control, spill, firefighting and incompatibility information. |
| Packaging | Container construction, cleanliness and quantity can affect handling and contamination risk. |
| Storage conditions | Temperature, humidity, segregation and shelf-life requirements may be product-specific. |
| Traceability | Batch, CoA or manufacturer documentation may be required depending on application. |
For broader industrial chemical sourcing, see Industrial Chemical Distributor Karawang.
Cells and battery systems are not ordinary freight
Battery logistics can introduce short-circuit, damage, thermal and dangerous-goods considerations that depend on cell chemistry, size, state, packaging and mode of transport.
International transport requirements for lithium batteries use the UN dangerous-goods framework. Lithium cells and batteries intended for transport are generally required to be of a type demonstrated to meet the applicable tests in UN Manual of Tests and Criteria subsection 38.3.
That transport requirement should not be confused with a universal factory-safety certification. Transport, product safety and workplace safety use different standards and regulatory frameworks.
Short-circuit prevention
Exposed terminals and conductive objects require controls appropriate to the battery and handling stage.
Physical damage
Handling methods should avoid crushing, puncture, drop and other mechanical damage.
Packaging
Transport packaging should follow the applicable battery classification, mode and dangerous-goods requirements.
Damaged batteries
Suspect, damaged or defective batteries can require handling arrangements different from normal production material.
Lifting
Large modules and packs may require engineered lifting or handling equipment based on actual weight and geometry.
Documentation
Transport classification, test information and shipment documentation should match the specific product and transport route.
Use the standard that matches the application
| Reference | Relevant scope | Do not misapply it |
|---|---|---|
| IEC 62660 series | Secondary lithium-ion cells for propulsion of electric road vehicles. | Not a general standard for every industrial lithium battery or factory MRO item. |
| IEC 62619:2022 | Safety requirements for secondary lithium cells and batteries used in industrial applications. | IEC notes that more specific application standards take precedence where applicable; road-vehicle cells use the IEC 62660 series. |
| IEC 63056:2020 | Additional safety requirements for secondary lithium cells and batteries used in electrical energy storage systems. | Do not automatically apply it to road-vehicle propulsion batteries. |
| UN Manual of Tests and Criteria 38.3 | Transport testing for lithium cells and batteries. | It is not a complete manufacturing-facility safety standard. |
| IEC 61340-5-1:2024 | ESD protection for susceptible electronic devices and assemblies. | Applies where ESD-sensitive electronics are handled; not every battery-process area needs identical controls. |
| SNI ISO 45001:2018 | Occupational health and safety management-system framework. | Does not prescribe the detailed engineering design of a battery production line. |
Technical traceability matters more as the process becomes more controlled
The old article presented digital tracking and IoT as mandatory characteristics of an EV battery supply chain. Digital systems can be useful, but the underlying requirement is reliable traceability and process control.
Manufacturer
Know who made the component or consumable and whether it is an approved source.
Exact part
Preserve part numbers, grades, revisions and technical parameters.
Batch / lot
Where process quality requires it, maintain batch or lot information through receipt and use.
Certificate
Retain CoA, calibration, conformity or manufacturer documentation when required by the specification.
Storage condition
Products sensitive to moisture, temperature or shelf life need documented storage controls.
Substitution approval
An apparently equivalent material should not enter a qualified process without the required technical approval.
Being located in Karawang is not an EV-industry qualification
The expansion of battery manufacturing can create opportunities for nearby industrial suppliers, but geographical proximity should not be confused with technical capability.
A supplier may be useful for one category and unsuitable for another. Routine facility consumables, for example, have very different qualification requirements from a process-contact chemical, calibrated measuring instrument or safety-critical electrical component.
The sourcing process should therefore match supplier qualification to the risk and technical importance of the item.
Criticality is more useful than the word “EV” when deciding what to stock
| Item condition | Inventory implication |
|---|---|
| High consequence + long lead time | Evaluate strategic spare stock or another documented recovery strategy. |
| High consumption + predictable usage | Use consumption history and replenishment lead time to establish reorder levels. |
| Low consumption + readily available | Local or distributor stock may be more economical than keeping excessive plant inventory. |
| Safety / compliance critical | Maintain required availability based on hazard and regulatory/site requirements. |
| Qualified process consumable | Consider shelf life, approved manufacturer, batch requirements and change-control risk. |
| Imported proprietary spare | Manufacturer lead time may justify inventory even if failure frequency is low. |
For maintenance inventory and replacement-component sourcing, see Supplier MRO Karawang.
How to qualify a requirement from a battery or EV facility
Identify the process area
Cell production, electronics, module/pack assembly, utilities, warehouse, laboratory, maintenance or general facility.
Identify whether the item contacts the process
A direct process material usually requires tighter qualification than a general facility-maintenance item.
Capture the exact specification
Manufacturer, part number, grade, dimensions, rating, purity, standard or drawing as applicable.
Identify safety requirements
Review chemical, electrical, ESD, fire, mechanical and workplace hazards relevant to the item.
Check qualification status
Determine whether the customer allows equivalents or requires the approved manufacturer and exact specification.
Verify documentation
Datasheet, SDS, CoA, calibration certificate, conformity documentation or transport information as required.
Confirm availability
Separate actual stock from estimated import or manufacturer lead time.
Document any substitution
Never silently replace a specified component or process material because a similar-looking item is easier to source.
What to send for EV battery and industrial MRO sourcing
Process / equipment
Identify the production area, machine, utility, maintenance task or facility application.
Exact product identity
Manufacturer, part number, chemical name, grade, model or approved reference.
Technical specification
Electrical rating, dimensions, material, purity, accuracy, capacity or relevant standard.
Required documentation
Datasheet, SDS, CoA, calibration certificate, compliance evidence or manufacturer declaration where required.
Alternative policy
State whether substitutions are prohibited, permitted or subject to customer engineering approval.
Commercial need
Quantity, package size, delivery location, required date and whether the requirement supports production, maintenance or project work.
