Smooth customs clearance depends on a complete, consistent document set. Every cooking oil shipment from Narisaralook Oil Export is supported by a standard package of export documents, with additional certificates and legalization available on request for markets that require them. This page explains each document, who issues it, and why customs authorities ask for it.
If you are planning your first shipment, read this checklist together with our step-by-step import guide and the FOB vs CIF comparison.
| Document | What It Confirms |
| Commercial Invoice | The transaction value, terms of sale and full product description used for duty assessment |
| Packing List | Quantities, packaging formats, net and gross weights per carton, drum, tote or flexitank |
| Bill of Lading (B/L) | The carrier's receipt and title document for the cargo shipped from Laem Chabang or Bangkok |
| Certificate of Origin (CO) | Official confirmation that the goods originate in Thailand |
| Phytosanitary Certificate | Plant-health certification for the oil seeds and vegetable oil cargo, issued by the Thai authority |
| Fumigation Certificate | Confirmation that fumigation treatment was performed for the shipment |
| Certificate of Analysis (COA) | Laboratory results for the batch, including parameters such as free fatty acid, moisture and peroxide value |
| SGS / FIGICO Inspection Report | Independent quality and quantity inspection where SGS or FIGICO has been appointed |
Our production quality systems behind these documents are summarized on the certifications page (ISO 22000, HACCP, GMP, HALAL, with SGS testing).
The Certificate of Origin is one of the most consequential documents in the set. Customs authorities use it to confirm Thai origin and to classify your duty rate. Some destination countries apply preferential tariff treatment to goods of Thai origin when supported by a Certificate of Origin, which can meaningfully change your landed cost.
Because preferential treatment depends on the trade arrangement between Thailand and your country, confirm the applicable rate and required origin format with your customs broker before ordering. Our export team prepares the Certificate of Origin through the official Thai issuing process for every shipment.
Each shipment includes the Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, Phytosanitary Certificate, Fumigation Certificate and Certificate of Analysis. SGS/FIGICO inspection reports are included where inspection has been appointed.
The Certificate of Origin (CO) is an official document stating that the goods were produced in Thailand. Customs authorities use it to verify origin, apply the correct import duty classification, and confirm eligibility where a destination country offers preferential tariff treatment to Thai-origin goods. Ask your customs broker whether your country applies preferential rates against a Thai Certificate of Origin.

Yes. Every shipment is supported by a Certificate of Analysis reporting the quality parameters of the batch, such as free fatty acid, moisture and peroxide value, so buyers and customs can verify the product against the agreed specification.
Letter of Credit requirements are set in each L/C and commonly include the Bill of Lading, Commercial Invoice, Packing List, Certificate of Origin and specified certificates.
