HS Code 8421.91 – Centrifuges; parts thereof, including parts for centrifugal dryers
HS code 8421.91 is the 6-digit subheading for centrifuges, parts thereof, including parts for centrifugal dryers. It is used for centrifuge bowls, centrifuge rotors, centrifuge baskets, drive shafts for centrifuges and centrifuge seals.
What HS 8421.91 covers
This HS code specifically covers parts for centrifuges, including those for centrifugal dryers. Centrifuges are vital machinery used across numerous industries such as chemical, pharmaceutical, food processing, wastewater treatment, and biotechnology for separating substances of different densities. The trade in these parts is crucial for the maintenance, repair, and upgrade of existing centrifugal equipment, ensuring their continuous and efficient operation. Importers are typically industrial plants, maintenance and repair organizations (MROs), and specialized equipment service providers. Exporters are often the original equipment manufacturers (OEMs) or specialized parts suppliers, highlighting the global supply chain for industrial machinery components and the importance of keeping complex separation processes running smoothly.

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).
