Seat adjuster classification treated as a motor vehicle accessory, not a part of seats, under tariff headings.

The seat adjuster was examined for tariff classification under Heading 9401 as a part of seats or under Heading 8708 as a motor vehicle part or accessory. On the facts, it consisted of rails and a mechanism fitted to the lower cushion to enable forward and backward movement, but the seat remained complete and functional without it. The ruling applied the distinction between a part, which is essential to the identity or function of the seat, and an accessory, which adds convenience and efficiency. The item was treated as an accessory rather than a seat part, and classification under Heading 9401 was rejected. It was held classifiable under Heading 8708.

Issues: Whether the product "seat adjuster" is classifiable under Heading 9401 as parts of seats or under Heading 8708 as parts and accessories of motor vehicles.

Analysis: The dispute turned on whether the product was an essential part of a seat or merely an accessory that improves seat adjustment and convenience. The relevant tariff entries were Heading 9401, which covers seats and parts thereof, and Heading 8708, which covers parts and accessories of motor vehicles. On the facts found, the product was an assembly of rails and related mechanism fitted to the lower cushion of the seat to permit forward and backward movement. The seat remained complete and functional without it, so the item did not answer the description of a "part" of a seat. Applying the distinction between part and accessory, the product was held to be an accessory that enhances convenience and efficiency. The interpretative aids relied on also supported classification under Heading 8708, which is wide enough to cover such accessories of motor vehicles.

Conclusion: The seat adjuster is not classifiable under Heading 9401 and is classifiable under Heading 8708; the classification claimed by the applicant was rejected.
