Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the scale is not mounted on a conveyor but measures weight in a hopper or feeder
Other weighing machinery may apply if the device does not involve a conveyor belt but still performs continuous weighing.
If the screw feeder is the primary function and the scale is auxiliary
Mechanical appliances for projecting, dispersing or spraying liquids or powders may apply if the feeder is the main component.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Determine whether the scale is a separate weighing device or an integral part of the screw feeder, as this affects classification
• The CBSA may require a detailed description of the weighing mechanism to confirm it qualifies as a continuous scale
• If the system includes a controller, ensure it is declared as part of the scale or separately, depending on its presentation
