The Philippine Tariff Finder Facility is a key resource for accessing tariff-related information on imports and exports, helping businesses determine proper classifications. It works alongside IPOPHL, which safeguards intellectual property rights under its “DREAM” mandate. The Online Application System for Advance Ruling on Tariff Classification (TCIS-OAS) enables digital filing for tariff rulings under Republic Act No. 10863 or the Customs Modernization and Tariff Act (CMTA). Complementing this, TCC Rulings from the Tariff Commission provide official guidance on tariff classification and trade matters, serving as a reference for importers, exporters, and regulators.
