Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pneumatic transport mechanism
Pneumatic continuous-action conveyors use air pressure and are distinctly provided for in 8428.32.
If primarily functioning as a rotary positive displacement pump
Screw devices acting mainly as pumps for liquids or slurries shift to Chapter 84 pumps, not conveyors.
If specialized for semiconductor wafer handling
Cleanroom conveyors for wafers may fall under machines for semiconductor processing per statistical notes.

Import Tips & Compliance
• For food or pharma use, ensure FDA-compliant materials (e.g
• stainless steel 304/316) and provide hygiene certifications
• Declare exact throughput capacity and length to confirm classification away from discrete-action lifts
• Avoid pitfalls by labeling as 'continuous-action' in invoices to prevent reclassification as pumps under 8413
