Meaning
Official lists of duty rates levied on imported goods are categorized according to standardized classification codes to facilitate international trade. Governments maintain customs tariff schedules to regulate the flow of imports and collect revenue based on the commodity classification of the shipped merchandise.
Trade Regulation
Customs authorities use these standardized lists to apply correct duty rates and monitor import quotas. Systematically organized customs tariff schedules ensure that all importers face the same legal requirements when declaring the same type of product. This consistency helps prevent arbitrary treatment of imported goods at border checkpoints.
Tariff Classification
Determining the correct code within the list requires a systematic application of the General Rules for the Interpretation of the Harmonized System. Under customs tariff schedules, a single digit difference in the code can change the duty rate from zero to over twenty percent. Importers must defend their selected classifications using technical product specifications during border inspections.
Revenue Collection
National revenues depend heavily on the proper enforcement of these schedules by border agents. In many developing economies, the enforcement of customs tariff schedules provides a significant percentage of the total government revenue. If an importer is found to have misclassified goods to pay lower duty rates, the government can assess back taxes, seize the shipment and impose severe financial penalties.
