Effective June 22, 2026, Thai Industrial Standards (TIS) for food contact paper and cooking paper will be enforced as mandatory for sale in the Thai market. This move has important implications for product licensing and tightens hygiene, labeling, and chemical-safety requirements for food-contact and cooking paper products. Thailand is strengthening its regulatory framework for paper-based culinary materials against a backdrop of accelerating global commitments to ESG and sustainability, as such materials—particularly those derived from natural or recycled fibers—have emerged as key alternatives to plastics in food preparation, cooking, and packaging applications. As a result, regulators worldwide are tightening controls to ensure that sustainability initiatives do not compromise consumer safety, particularly regarding the potential migration of chemical substances into food. Regulatory Framework: Voluntary vs. Mandatory Standards Standards under the TIS regime are generally classified into two categories. Voluntary standards allow manufacturers or importers to apply for a product license and affix the TIS mark to demonstrate product quality and build consumer confidence, but compliance is not legally required. Mandatory standards, by contrast, require manufacturers and importers to obtain a product license and affix the TIS mark before placing products on the Thai market, and noncompliant products cannot be legally sold. Previously, the TIS standards for food contact paper (TIS 2948-2562) and cooking paper (TIS 3438-2022) fell under the voluntary standard regime, meaning that obtaining a TIS license and displaying the TIS mark was optional. However, due to the increasing use of paper in food preparation and cooking, the Thai Industrial Standards Institute has determined that upgrading these standards to mandatory status is necessary to enhance consumer safety. As a result, all paper intended for food contact or cooking purposes must now obtain a TIS product license prior to sale in Thailand. Scope of the Standards The primary distinction between the
