Quality and Product Documentation
How product quality is checked and documented, and which documents buyers can request before and after an order.
Our Approach to Quality
Quality starts with a clear specification. Before an order is confirmed, the buyer and THAI AGRO OILS agree the grade, the limit for each quality parameter, and the documents that will accompany the goods.
Send your required specification with your enquiry. If you do not have one, tell us how the oil will be used and our team will discuss suitable grades with you.
Certificate of Analysis
A Certificate of Analysis (COA) is a laboratory report with test results for a specific batch. Buyers compare it against the agreed specification before accepting a shipment.
Tell us in your enquiry if you need a COA with each shipment, and which parameters it must cover.
What Buyers Usually Check
Common quality parameters for refined vegetable oils and what each one tells you. Limits differ by oil and grade and are agreed in the contract. Each product page lists the parameters buyers usually check for that oil; shipping documents are covered on Export & Logistics.
| Parameter | What it tells you |
|---|---|
| Free fatty acids (FFA) | How far the oil has broken down; low values indicate good refining and fresh oil. |
| Peroxide value | Early oxidation; rising values mean the oil is starting to go rancid. |
| Moisture and impurities | Water and solids in the oil, which shorten shelf life. |
| Iodine value | How unsaturated the oil is; also helps confirm the oil type. |
| Colour (Lovibond) | How well the oil has been bleached; buyers often set a maximum red value. |
| Cloud point / melting point | The temperature at which oil clouds or melts; important for palm olein and coconut oil. |
Certifications
Certificates will be shown here with the issuing body and expiry date once copies are supplied. No certification is claimed until then.
Food safety certificates
Many importers and food manufacturers ask for evidence of a food safety management system at the producing facility.
Halal certificates
Required by buyers in many markets in the Middle East, Africa and Asia, and by some food brands elsewhere.
Market-specific documents
Health certificates, certificates of origin and non-GMO statements, depending on the product and destination.
Third-Party Inspection
Many importers ask an independent inspection company to check quantity and quality at loading. If you need one, name it in your enquiry so inspection can be planned into the order.
