Quick answer
Six groups are essential: material name and grade, supplier and production address, composition, applicable standard and quality grade, batch number and test date, and a stamped, signed conclusion. The specification must also state carriers, solvents and additive sources, with halal certificate numbers for animal-derived items. A Zhengzhou flour mill checked each sheet against a field list and returned incomplete ones on delivery, faster than supplementing after acceptance.
Detailed explanation
Mandatory fields explained
| Field group | Check point |
|---|---|
| Name and entity | Grade, supplier legal name and site match the certificate |
| Composition | All ingredients, carriers and aids; animal-derived items sourced |
| Traceability | Batch number, production and test dates, report number |
| Conclusion | Pass result, analyst and authorized signatory, supplier stamp |
How COA and halal certificate connect
The specification answers what the material is, while the halal certificate answers whether the source is acceptable; grade and supplier name must match exactly across both. The COA batch number should trace to the delivered lot, and imported materials should also align with the certificate of origin and invoice.
Frequently invalid forms
Copies without the supplier stamp, test dates predating the current standard version, and composition lines saying other or additives as needed do not count as valid technical documents. The Zhengzhou mill embedded the checklist into incoming inspection, so specifications with missing fields never entered the approved-supplier file.
