North American Industry Classification System
CBP applies GRI 2(a), which extends classification of a complete article to incomplete or unfinished articles that have the essential character of the finished good. A partially assembled conveyor system shipped with its drive units and structural frame will typically be classified as a complete conveyor rather than as parts, but a binding ruling is advisable for high-value systems.
NAICS 33392 encompasses elevators and moving stairways (333921), conveyors and conveying equipment (333922), overhead cranes, hoists, and monorail systems (333923), and industrial trucks, tractors, trailers, and stacker machinery (333924).
