HS Code for Screw conveyor
Screw conveyors, also known as auger conveyors, are classified under HS code 842839. This code serves as a residual category for continuous-action elevators and conveyors for goods or materials that are not specifically named in other subheadings of heading 8428. While 842832 covers bucket-type conveyors and 842833 covers belt-type conveyors, the screw conveyor utilizes a rotating helical screw blade within a tube or trough to move liquid or granular materials. Because the screw mechanism does not fit the technical definitions of pneumatic, bucket, or belt systems, it falls into the "other" category of 842839. This classification applies to the complete mechanical unit designed for the transport of materials. These machines are widely used in agriculture for grain handling and in industrial settings for moving powders, chemicals, or waste products.

Common Misclassification
Screw conveyors are often misclassified under 842833 (belt conveyors) or 842820 (pneumatic elevators). They may also be incorrectly filed under 843139, which is the code for parts of conveyors rather than the complete machine. If the screw is part of a specific agricultural machine (like a combine harvester), it might be classified in Chapter 8433 instead.
