Importers and exporters in Thailand register with the Customs Department and, for controlled goods, obtain permits from the relevant agency. Factories using machinery above the legal threshold or with more than the set number of workers need a factory licence (Ror Ngor 4) from the Department of Industrial Works. Zoning and environmental rules apply.
How it works
