Before exporting Solder Paste to Thailand in Southeast Asia, both document preparation and production line shipment plans must be launched simultaneously, as the FORM E certificate of origin usually takes 3 working days from application to issuance, and Thai customs implements 100% document verification for solder paste chemical products. Once the HS code (38109000) on the commercial invoice does not match the actual cargo composition sheet, inspection will be triggered directly. Last month, we encountered a shipment that was detained at Bangkok Laem Chabang Port for 5 days due to a 0.3% deviation in the marked tin powder content.

The MSDS for all export solder paste must be issued by a third-party laboratory with CNAS qualification, and self-made versions from manufacturers cannot be used. It is especially necessary to ensure that key parameters such as flash point, heavy metal content, and lead-tin ratio are completely consistent with the actual batch test data. The Ministry of Industry of Thailand requires that the MSDS validity period must not exceed 2 years and must be accompanied by a Thai translation. We recommend embedding the Thai translation in advance into the original MSDS template to avoid delays in later re-endorsement.

The certificate of origin CO and FORM E must be issued by the same declaring enterprise, and the four elements of invoice amount, product name, quantity, and gross weight must be 100% consistent with the customs declaration form. Even if the customer order number in the packaging box mark has one extra letter, it will lead to customs clearance failure. Last year, a customer in Shenzhen was deemed to have false information by Thai customs and the entire container was returned due to mistakenly adding the words 'FOR REFERENCE ONLY' on the box mark.

For solder paste export, SGS test reports for each batch must be provided, focusing on verifying four indicators: solid content, viscosity, metal content, and halogen residue. Among them, the halogen residue must be lower than 900ppm to meet the requirements of Thailand's "Hazardous Substance Control Regulations" B.E.2550. Our production line tests found that if the ion residue on the PCB surface after Reflow Soldering exceeds the standard, it is often caused by falsely marked Cl? values in the SGS report of the solder paste batch.

The commercial invoice must indicate the specific model of the solder paste, rosin type (R, RMA or RA), carrier solvent composition, and whether it contains nano-sized tin powder. Thai customs has recently listed the word 'NANO' as a highly sensitive term. If it is not clearly stated on the invoice but appears in the technical data, it will be regarded as intentional concealment and a 35% anti-dumping additional tax will be levied. When we helped a customer in Dongguan remedy the situation, we found that their solder paste actually added 50nm tin powder but the invoice stated ordinary spherical powder, and customs clearance was finally completed by providing the original data of the laser particle size analyzer.

All copies of documents must be affixed with the enterprise's Chinese-English official seal and cross-page seal. The original FORM E must be separately sealed and submitted by the freight forwarder along with the goods. The electronic PDF cannot replace the paper original. Thai customs does not accept any form of electronically issued certificate of origin. We once had two shipments that were judged invalid and had to be reapplied for due to blurred handwriting on the original FORM E caused by moisture during express delivery.
