The tariff classification of a slewing ring from England
Issued October 20, 1995 by U.S. Customs and Border Protection.
Tariff classification
HTS codes: 8483.90.5000
Headings: 8483
Product description
The item at issue is commonly known as a geared slewing ring. This is normally a large (3' to 20' diameter) steel structure assembled from two concentric custom-made forged steel rings, one of which has gear teeth cut into it. The rings are capable of rotation, separated by rows of steel balls. Each forged ring has a number of drilled holes located in a circular pattern between the inside and outside diameters of each ring. These holes are used for fastening the slewing ring both to the base and to the rotating member of the machine that it is attached to. While the steel balls and ground raceways machined into the rings provide rotational antifriction properties, the gear teeth, when intermeshed with a driven pinion gear, provide rotational torque transfer. Slewing rings of this nature are commonly mounted between the upper rotating structure and the lower non-rotating structure of cranes and similar construction machinery. It is the established policy of Customs to consider these articles to be essentially gears.
CBP rationale
The applicable subheading for the slewing ring will be 8483.90.5000, Harmonized Tariff Schedule of the United States (HTS), which provides for parts of gearing, gear boxes and other speed changers.
