Last updated: August 2026 dataOptical sorters, gravity separators, indent cylinders, and air-screen cleaners used at grain elevators, seed-processing facilities, and pulse-handling plants are all captured under this heading, which maps to a single US tariff line, 8437100000. Italy is the leading supplier, with the United Kingdom and Canada also prominent — European manufacturers dominate the high-throughput optical and gravity-separation segment. Equipment classified here is distinct from milling machinery (heading 8437.80), so machines that both clean and mill grain in a single integrated unit require careful classification analysis.

A machine that performs both cleaning/sorting and milling functions is classified by its principal function under GRI 3(b). If cleaning is the primary design purpose, 8437.10 applies; if milling predominates, 8437.80 is correct. Manufacturers' specifications and marketing materials describing the machine's primary function are key supporting evidence.
Yes, provided the machine's essential character is grain or seed sorting. Under Section XVI Note 4, incorporated control and vision systems are classified with the host machine. The presence of sophisticated electronics does not shift classification to Chapter 84 or 85 when the sorting function defines the product.
