Efficiency and predictability in the global supply chain are critical for business operations. Whether involved in manufacturing, distribution, logistics, or even in the provision of services, most business operators rely upon problem-free customs clearance in the countries in which they operate. If customs disputes do arise and are not effectively addressed, they can have a profound impact on operations, delaying delivery, creating potential civil and criminal liabilities, or even resulting in the seizure of imported goods. Often, importers or their agents can become complacent, particularly where there has been a period of months or even years of customs clearance without encountering any issues. However, disputes can arise, often relating to origin of goods, classification, and duty assessment. When not addressed early in the dispute process or through settlement, a dispute can escalate, leading to issuance of official letters of assessment by customs authorities. Once Thai customs has issued such a formal letter of assessment to an importer, discretion in settlement is gone and only the full value of the duty assessment can be accepted. At this stage, the only legal avenue for challenge is to accept the duty assessment or to litigate. This article addresses post-assessment litigation options to challenge official customs duty assessments. Customs Board of Appeals Once an official assessment is made, an importer has the right to seek a formal appeal of the customs assessment with the Customs Board of Appeals or to otherwise make payment of the full assessment within 30 days of the date it received the assessment. Extensions of time are not permitted. With few exceptions, the right to appeal does not allow the importer to defer an assessed duty payment. This means that the importer must post security for the assessed duty at the time of filing the appeal. This essentially means

Thailand’s legal system is based on European continental civil law systems, with a three-tier court system. Precedents set by the Thai Supreme Court are merely considered as examples of the application of laws and are not binding on Thai courts. While the country’s judiciary and dispute resolution mechanisms are well developed, some aspects can be unfamiliar or even surprising to counsel unfamiliar with the Thai court system. This article introduces some of the Thai civil court procedures and practices, and covers several key issues it is important to understand regarding civil litigation in Thailand. Offers of compromise or settlement In Thailand, there is no such thing as an ‘offer without prejudice’. Anything put in writing can be used against the offering party. Therefore, compromises, settlements, and offers to compromise or settle should not be made before consulting with legal counsel. Similarly, parties at trial or anticipating litigation should be cautious in all communications with the opposing party. Location of assets Before initiating litigation, plaintiffs should investigate the nature and extent of the defendant’s assets in Thailand and abroad. A monetary judgment is of limited value if the defendant has little or no recoverable assets. Therefore, any information a claimant has on the opposing party should be assessed at the beginning of the case or as soon as is reasonably possible. Language of documents All documents submitted to a Thai court must be in the Thai language. Foreign documents must be the originals or certified copies, and certain documents also need to be notarised and then authenticated by a Thai consular official. Court costs A plaintiff must pay a court filing fee when submitting a case. This is usually 2% of the claim amount but will not exceed THB 200,000 per action for claims of up to THB 50 million.

A significant new procedural law for fines in Thailand results in the mass removal of certain types of fines for criminal penalties and alters procedures for certain administrative monetary penalties.   There are generally two types of fines imposed under Thai law: criminal fines and administrative fines. However, there will soon be a type of fine that exists outside of the criminal or administrative legal mechanisms: the phinai fine, which is neither a criminal penalty nor an administrative fine. Instead, a phinai fine—which must be paid to the state—is one assessed in lieu of criminal penalties for less-serious offenses. Perhaps the closest equivalent to a phinai fine would be a “civil” fine, but there is no official translation of Thailand’s first law dedicated to these fines, the Act on Phinai Fine Proceedings B.E. 2565 (2022) (ACFP), which was published in the Government Gazette on October 25, 2022. Before proceeding further to discuss the significance of the new law, a note should be made regarding the term phinai. As there has been no official translation of the ACFP, there is currently no official translation of phinai. Under the ACFP, “to seek a phinai fine” (or prap pen phinai) was determined to have the specific meaning of ordering a phinai penalty offender to pay a phinai fine. The meaning of the term as defined reflects a type of phinai penalty, which is neither a criminal penalty nor an administrative fine. In the future, there is a possibility that the official translation of the ACFP may use a different term. The passage of the ACFP provides Thailand with a special procedural law for all phinai fines, ultimately resulting in a significant change in the categorization and collection of fines and administrative monetary penalties. Other than two sections on administrative preparations that took
