For products manufactured abroad, the manufacturing site's GMP and quality data are reviewed against the application route and product scope. Thailand uses ASEAN GMP as the reference, with separate guidance for regular factories and for small-scale manufacturers with low-risk processes.
Raw-material quality data has a checklist. It starts with the scientific name (plant, animal or mineral) and the formulation of the principal herbal ingredient, and the level of requirements differs between herbal products for health and herb-derived medicines. The label and package insert must state the name and content of the active ingredients in the manner set by the notification.
At import customs, the manufacturer's certificate of analysis (CoA) must be held and kept on file, and the shipment must pass inspection at a designated checkpoint. For a business importing raw materials, this document is the core of clearance. Samples before registration come in under the sample manufacturing or import notification (form ตย.1); there is an automated processing system, but the relevant manufacturing or import licence must already be in place.
