How Is Halal Certification Done for OEM / Contract-Manufactured Products? The Division of Responsibility Between Brand and Manufacturer

In Malaysia, products manufactured by a contract manufacturer (OEM / ODM / subcontract manufacturing) on behalf of a brand can equally obtain JAKIM halal certification; the corresponding application category is "Contract Manufacturing / OEM", one of the nine categories listed by the official Portal Halal Malaysia. The key principle: the halal certificate is held by "the party with physical process control"—usually the contract manufacturer that holds the GMP plant and actually produces the goods; a brand without its own factory then works with an already-JAKIM-certified contract manufacturer to have its own products carry the mark. All outsourced processes must be halal-certified or carried out under strict control—no segment may be a black box.

Three common structures of OEM halal

Contracts and documents: where things most easily go wrong

• The OEM contract must clearly specify the allocation of halal responsibility: who is responsible for the ingredient halal certificates, how formula changes are notified, and the scope of use of the halal mark.
• The industry-recognised pain point is precisely that OEM contracts are not standardised and the halal status is vaguely defined, leading to unclear responsibility at audit and finger-pointing.
• When the brand changes the formula or the ingredient supplier, it must promptly notify the contract manufacturer to update the halal system; otherwise the certificate's coverage will diverge from the actual product.

Line isolation and multi-brand management

When non-halal products are produced on a shared line, there must be a dedicated production line or a validated cleaning procedure; where multiple brands share a line, the ingredient source of every SKU must be traceable. This follows the same logic as halal ingredients and supplier management—JAKIM looks at the whole supply chain, not a single link.

Renewal and changes

An OEM / contract-manufacturing halal certificate is generally valid for 2 years; apply for renewal at least 3 months before expiry. Adding items or changing the formula counts as a "change" and must go through the change procedure, rather than being lumped together at the next renewal. For audit and renewal details, see halal renewal and audit.

The on-site due diligence the brand should do

When choosing a contract manufacturer, do not just look at whether they hold a halal certificate—confirm that your product item is actually listed in that plant's halal product list and that the ingredients you intend to use are already approved within its halal system. It is advisable to walk the plant flow in person, to see whether non-halal products share the line, whether cleaning and line-changeover records are properly kept, and whether the ingredient warehouse has zoned management. The contract should also make "prompt written notification of any change of formula or ingredient" an obligation, and stipulate how liability and compensation are allocated if a halal violation on the manufacturer's side causes the certificate to be revoked. These seemingly tedious upfront checks can prevent major losses down the line—the mark being suspended, or an entire consignment being stuck in the channel and forced off the shelf. If the brand and the contract manufacturer can define the boundaries of responsibility clearly at the start of the partnership, every subsequent audit and renewal becomes far easier.

Frequently asked questions (FAQ)

Q: I don't have my own factory—can I still get halal certification? Yes. Having a contract manufacturer that already holds JAKIM halal certification produce your goods, and bringing your product into its halal system and product list, is the route most brands without their own plant take.

Q: Is the halal certificate held by the brand or the contract manufacturer? Usually by the contract manufacturer that actually produces and holds the plant and GMP; the brand is the principal. Who holds the certificate depends on the applying entity and process-control authority, and this must be clearly defined in the contract.

Q: Does an outsourced segment of the process (e.g. filling, packaging) also need to be halal? Yes. All outsourced processes must be halal-certified or carried out under strict control—no segment may be uncontrolled.

Q: Is it a problem for multiple brands to share the same production line? As long as each brand's ingredient sources are traceable, the line has cross-contamination-prevention measures, and each is listed separately, it is fine; the source documents and accounts must reconcile.

Q: Do I need to re-apply when changing ingredient supplier? Not necessarily a re-application, but it counts as a change and must be notified to the contract manufacturer to update the halal assurance system documents, confirming that the new ingredient's halal proof is valid.

Self-check checklist

• [ ] Confirmed the certificate-holding entity (contract manufacturer or brand) and written it into the contract
• [ ] All outsourced processes are within the halal coverage
• [ ] The allocation of responsibility for ingredient halal proof is stated in the OEM contract
• [ ] Products sharing a line have isolation or cleaning validation
• [ ] A mechanism exists for notifying and updating formula or supplier changes

Conclusion

The core of OEM halal is not "who produces" but "who controls the process, who holds the certificate, and who is responsible for ingredient halal". Nail these three things down in the contract, and update the halal system in sync whenever the formula or supplier changes, and there will be no vacuum of responsibility at audit.
