Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

8413.91.90Same rate: 35%

If designed for liquid pumps not powered by fluid displacement

Parts for general liquid pumps (non-hydraulic fluid power) fall under the broader 'other pumps' subheading.

8431.49.90Same rate: 35%

If used in parts of machinery for semiconductor wafer processing

Pump parts integral to semiconductor manufacturing equipment are classified in Chapter 84 as parts of those machines.

8413.60.00Same rate: 35%

If imported as part of a complete hydraulic pump assembly

Complete hydraulic fluid power pumps, including integrated parts, are classified under the specific pump heading rather than parts.

Import Tips & Compliance

Verify the part is exclusively for hydraulic fluid power pumps via manufacturer specs to avoid reclassification

Include detailed engineering drawings and end-use certification in documentation to confirm HTS accuracy

Watch for undervaluation pitfalls; provide cost breakdowns separating from complete pump assemblies
