Frequently Asked Questions
How does the material composition of pump impellers and parts affect their HTS 841391 classification?
The material is critical for determining the correct 8-digit subheading; for example, impellers of plastics fall under 8413.91.10, while those of base metals (e.g., cast iron, steel) are classified under 8413.91.50. This distinction impacts applicable duty rates and may trigger additional duties or trade remedies specific to the material, such as antidumping orders on certain steel or cast iron articles.
What specific customs risks exist when importing pump parts under HTS 841391 that could lead to inspection or detention?
The primary risk is the potential misclassification of complete pump assemblies or functional units as 'parts', as customs authorities scrutinize whether imported components constitute nearly complete pumps. Inspectors also frequently verify the country of origin marking on each individual part, as unmarked or improperly marked items can lead to delays and penalties. Additionally, shipments containing impellers may be examined to ensure they are not controlled dual-use items related to nuclear or chemical applications.
What additional duties or fees might apply when importing pump parts and impellers under HTS 841391?
Parts of pumps for liquids under HTS 841391 are typically subject to the U.S. Most-Favored-Nation (MFN) duty rate of 2.5% ad valorem, but you must also account for merchandise processing fees (MPF) and potential Section 301 tariffs if the parts originate from China. The specific country of origin and any applicable trade programs (e.g., USMCA) will be the primary determinants of your final landed cost.
Classification by Material for Pump Parts & Impellers
The classification of part 841391 is not changed by the material of construction. Parts of pumps, including impellers, made of any material (e.g., cast iron, stainless steel, bronze, engineered plastics, or composites) are all classified together in this subheading. This contrasts with other headings where material (e.g., plastic vs. metal) can shift classification to a different chapter. The critical factor is that the part is identifiable as being solely or principally used with pumps of heading 8413. Therefore, an impeller made of PPS plastic (841391) is classified identically to one made of bronze (841391).
Confused with Similar Parts & Machinery
Parts for pumps (8413) are frequently confused with parts for other machinery in Chapter 84, particularly parts for compressors (8414) and liquid elevators (8413.70). For example, an impeller for a centrifugal compressor is correctly classified under 8414.90, not 8413.91. Additionally, note that complete pump units are classified in heading 8413.10 through 8413.70 based on type and application, while parts are in 8413.91 (glands, seals, etc.) and 8413.92 (impellers).
