1. Plant origin is a starting point—not a finished-product conclusion
TAS 8400-2025 gives a general principle that plant-derived materials are halal except poisonous or hazardous plants whose hazard has not been removed. Its scope, however, extends beyond fresh fruit to ingredients and processes across the food chain.
Once durian becomes a snack, the formula may include oils, flavours, additives or processing aids. A decision must follow the actual production formula and its evidence—not the ingredient name on the front of pack.
2. TAS 8400-2025 makes the chain scope explicit
Thailand's halal food standard, published in the Royal Gazette on 3 February 2026, covers receiving, preparation, processing, sorting, packing, marking and labelling, handling, transport, distribution, storage and food service.
A file that stops at an ingredient certificate therefore does not answer questions about the finished product's facility, contact points, package, storage or transport.

3. A formula change must trigger an evidence review
The same SKU name does not always mean the same formula. Control the formula code, version, effective date, ingredient list, suppliers and supporting records for additives, flavours and processing aids.
A supplier, manufacturing source, specification or substitute change should be evaluated for certification scope before old artwork or claims are reused.
4. Shared lines require contact prevention and cleaning controls
Codex CXG 24-1997 says preparation, processing, transport and storage should avoid contact with unlawful items, and addresses different sections or lines where measures prevent contact, together with appropriate cleaning.
Useful evidence includes the flow map, contact points, sequencing, cleaning method, verification and records for the actual run. ‘Shared line’ or ‘cleaned’ without scope and records is not a complete control story.
5. The mark and certificate must match the SKU and pack version
CICOT's portal separates new, additional, renewal and cancellation workflows for the halal certification mark and publishes 2025 rules for production processes, establishment/product inspection and mark use.
Marketing teams should verify the operator, facility, product, scope, validity and permitted artwork against the actual records. A mark image or certificate from another SKU is not substitute evidence.
6. Thai evidence does not prove readiness for every market
Codex notes that importing-country authorities may interpret requirements and apply specific conditions. CICOT's portal also maintains destination document sections, including one for the United Arab Emirates.
A destination check should remain separate from the domestic certificate: confirm recognised certification, procedure, documents, label and conditions applicable to the product category and shipment date.
7. Seven layers of a Halal Product Evidence File
This structure helps product, plant and market partners organise records. It is not a certificate or guarantee of inspection outcome.
- Product identity: SKU, name, formula, version and effective date
- Formula and inputs: ingredients, additives, flavours and processing aids
- Supplier and lot: specification, manufacturing source, documents and changes
- Process and contact: shared line, sequence, prevention and cleaning records
- Pack and claims: artwork version and mark-use authorisation
- Certification scope: operator, facility, product, validity and status
- Market and release: destination rules, shipment identity, review and approval owner
8. Thai origin and the limits of this article
Thai durian origin creates value when the finished pack can be traced to its SKU, formula, suppliers, facility and lot. Origin does not replace halal certification or destination requirements.
Siam Diamond Journal uses official sources to explain evidence structure only. It does not state that Siam Diamond uses a certified line, has a halal-certified product, may use a mark, or has met any destination's requirements.
