Motor vehicle classification controls customs exemption for tractor engine parts; agricultural tractors were treated as motor vehicles under tariff law.

Piston ring kits for agricultural tractor engines were held outside the exemption in Notification No. 172/89-Cus. because the notification excluded parts of engines interchangeable for use with motor vehicles. Chapter 87 was treated as covering tractors as motor vehicles for tariff purposes, so agricultural tractors were not outside the excluded class. The reference in Notification No. 59/87-Cus. to industrial and agricultural tractors did not change that position, and earlier tariff entries or decisions under different notifications were not treated as controlling.

Issues: Whether piston ring kits for agricultural tractor engines were eligible for exemption under Notification No. 172/89-Cus. on the footing that agricultural tractors are not motor vehicles, and whether Chapter 87 of the Customs Tariff Act, 1975 excludes agricultural tractors from the expression motor vehicles.

Analysis: The exemption in Notification No. 172/89-Cus. extended to goods falling under Heading 84.09 but expressly excluded parts of engines interchangeable for use with motor vehicles. The determination therefore turned on whether agricultural tractors were outside Chapter 87 or otherwise outside the class of motor vehicles. Chapter 87 was read as covering all kinds of motor vehicles, including tractors under Heading 87.01, and the scheme of the chapter was relied upon to show that the expression was not limited to road vehicles alone. The reference in Notification No. 59/87-Cus. to internal combustion piston engines for industrial and agricultural tractors did not alter this position, because the use of the expression other motor vehicles was taken to show that agricultural tractors were also treated as motor vehicles for tariff purposes. Earlier tariff entries and prior decisions under different notifications were held not to govern the present notification.

Conclusion: The imported piston ring kits were not eligible for exemption under Notification No. 172/89-Cus. and the claim failed.
