Export Documentation in Thailand: B/L Rules, Consignees, and the Details That Prevent Delays
- Nov 12
- 4 min read
Exporting goods can be an intricate process, especially when navigating the regulations surrounding export documentation in Thailand. The country's strict customs clearance policies require exporters to pay close attention to detail. Errors in essential documents like the Bill of Lading (B/L), the consignee information, shipping marks, and transshipment clauses can lead to significant delays or even rejection of shipments. Understanding these elements is critical for ensuring smooth transactions and timely deliveries.
Why Export Docs Fail
A common challenge exporters face in Thailand is the unforgiving nature of customs clearance, particularly regarding document consistency. For example, mistakes in the Bill of Lading, incorrect consignee/notify party details, mislabeling shipping marks, and unclear transshipment clauses can lead to shipment delays. Thai customs officials enforce stringent compliance, and failing to adhere to rules can result in costly consequences for exporters.
To avoid these issues, it's essential to understand what customs officials are looking for. They prioritize consistency and accuracy across all export documents, which includes not only the B/L but also the invoice, packing list, and any other relevant paperwork.
Bill of Lading Essentials (Seen by Carriers and Customs)
The Bill of Lading is arguably the most important document in the export process. Here are some key things to remember:
Consignee Must Be Clear and Valid
The consignee listed on the B/L must be a valid local company unless you are correctly inserting a transshipment clause. Moreover, if the B/L states "To Order," the notify party must still meet local requirements. Consult regional agent guidance to ensure compliance.
Shipping Marks Cannot Be Blank
Notably, many major liners operating in Thailand have strict policies regarding shipping marks. A blank shipping mark on a B/L is prohibited. Instead, ensure you include mark details or use "No Shipping Mark" only for specific cargo types like tank containers, as per OOCL guidelines.
Know What a Transshipment B/L Does
Understanding the function of a transshipment B/L is vital. This document serves to document transfers across carriers and routes, maintaining a continuous title and contract, especially vital if routing through hubs before final delivery.
Legal Framework
The Carriage of Goods by Sea Act (B.E. 2534) governs the B/L's legitimacy as a contract, receipt, and document of title. Courts enforce B/L clauses in alignment with this statute.

Export Pack: The Minimums You Need (Every Time)
A well-prepared export pack is essential for compliance. The following documents are necessary:
Commercial Invoice: Essential for customs declaration.
Packing List: Details the contents of the shipment.
B/L/AWB: These must be submitted via e-Customs, strictly aligned to HS and value rules.
Certificates of Origin: If claiming preference, such as under FTA/RCEP, ensure you meet the exact origin criteria; otherwise, you risk paying MFN duties.
Consistency of shipping marks and numbers across all documents is also essential. Avoid generic placeholders like “as per attached,” as this can raise red flags with liners and customs officials.

Preventing Holds: A 10-Point Export Doc Checklist
To ensure that your export shipment clears customs smoothly, adhere to this comprehensive checklist:
Confirm Consignee/Notify Structure Fit: Ensure the structure aligns with the destination and route.
Finalize Shipping Marks: Keep them identical on all documents to avoid confusion.
Verify HS Classification: Ensure it aligns with product descriptions in both the invoice and the B/L.
Pre-Validate Origin: Check with suppliers for validation of origin to avail preferential rates under ASEAN and RCEP agreements.
Use NSW e-Tracking: Ensure all linked permits appear in customs prior to loading.
Synchronize ERP with Broker and Liner Data: Prevent field-level mismatches during data entry.
For Health Products: Ensure FDA LPI is paired with the exact invoice data.
Keep Container Status Consistent: Maintain unit descriptions that align with carrier requirements.
Validate CIF/FOB Valuation Method: Verify with customs rules on handling surcharges effectively.
10. Archive a Digital Audit Trail: Maintain all documents and messages for post-clearance verification.
