HS Code for Centrifuge

Centrifuges are classified under HS code 8421.19. Heading 8421 is a broad category that includes centrifuges, including centrifugal dryers, as well as filtering or purifying machinery for liquids or gases. The classification of a centrifuge is based on its use of centrifugal force to separate substances of different densities. Subheading 8421.19 is the "other" category for centrifuges that do not fall into the specific niches of cream separators (8421.11) or clothes-dryers (8421.12). This code covers a wide range of equipment, from small laboratory centrifuges used for blood analysis to massive industrial centrifuges used in wastewater treatment or chemical manufacturing. The classification is determined by the machine's primary mechanical action of high-speed rotation to achieve separation. It is important to distinguish these from centrifugal casting machines or centrifugal sifting machines, which have their own specific headings based on their primary industrial function.

Products Included

• Laboratory centrifuges for research and medical diagnostics
• Decanter centrifuges for industrial sludge dewatering
• Centrifugal separators for oil and water mixtures
• Basket centrifuges for chemical processing
• Centrifugal dryers for industrial components (excluding clothes)

Common Misclassification

The most common misclassification for centrifuges is using 8421.12, which is strictly for clothes-dryers. Industrial centrifugal dryers used for plastic pellets or metal parts must stay in 8421.19. Another error involves laboratory equipment; while some lab tools fall under chapter 90, centrifuges are specifically named in 8421 and therefore must be classified there according to the Section XVI notes. Additionally, centrifugal pumps are sometimes confused with centrifuges, but pumps (8413) move liquid, while centrifuges (8421) separate materials within a liquid or separate liquids of different densities.

FAQ

What is the HS code for Centrifuge?

The HS code for most industrial and laboratory centrifuges is 8421.19.

Are laboratory centrifuges classified differently than industrial ones?

No, both laboratory and industrial centrifuges are generally classified under 8421.19, as the heading is based on the mechanical function rather than the scale of the equipment, provided they are not cream separators or clothes dryers.
