Classification of motor vehicle parts: ensure accurate descriptions and correct tariff classification to reduce assessment delays. Importers of motor vehicle parts must provide precise item descriptions and correct tariff classification to facilitate customs assessment and reduce dwell time. Goods specifically meant for use as automobile parts and accessories should be classified under the tariff heading covering parts and accessories of motor vehicles; importers may include technical names and part numbers in brackets to clarify the nature of the goods and avoid misclassification and examination difficulties.
