HS Code 8413.91 – Pumps; parts thereof
HS code 8413.91 is the 6-digit subheading for pumps, parts thereof. It is used for pump impellers, pump casings, pump shafts, mechanical seals and gaskets for pumps.
What HS 8413.91 covers
This HS code is dedicated to parts of pumps falling under heading 8413, playing a critical role in the global aftermarket and maintenance supply chain for fluid handling equipment. It includes components like impellers, casings, shafts, seals, valves, and other essential elements that allow for the repair, upgrade, or customization of various pump types. Major importers and exporters are typically countries with large industrial bases and extensive infrastructure, such as Germany, the USA, China, and Japan, where pump manufacturing and usage are high. The trade in pump parts is driven by the need for equipment longevity, operational efficiency, and rapid repairs to minimize downtime in industries ranging from oil & gas to water utilities. Accurate identification of the specific pump type the parts are for is crucial for correct classification and trade compliance.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
