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