Modular conveyor systems shipped in sections may be entered as a complete machine under a single HTS heading if they constitute a functional unit, or as separate components under their respective headings. The importer must demonstrate that the sections form a single machine with a unified function; otherwise, each section is classified independently. Consulting a customs broker before shipment avoids costly reclassification.

Belt conveyors sourced from certain countries may be subject to Section 301 tariffs, and steel or aluminum content in the frame and rollers can trigger Section 232 considerations. The applicable measures depend on the country of origin and the specific HTS subheading; importers should request a binding ruling or broker review before committing to a sourcing decision.
