HS-4 · Heading
8421 — Centrifuges, including centrifugal dryers; filtering or purifying machinery and apparatus for liquids or gases
Chapter 84: Nuclear reactors, boilers, machinery
Plain-language overview
Use HS-4 8421 when importing centrifuges, such as cream separators or centrifugal dryers, and filtering machinery for liquids or gases. For instance, if you're bringing in a machine designed to separate cream from milk, this is the correct heading.
To differentiate between subheadings, consider the specific function of your equipment. For example, 842111 covers cream separators, while 842112 is for clothes-dryers. If your centrifuge is not specifically for these uses, check 842119, which includes other centrifuges not classified elsewhere.
When filtering machinery is involved, the choice depends on the type of liquid or gas being processed. 842121 is for water purification, while 842122 focuses on beverages. If your machinery purifies oil or petrol, refer to 842123. For other liquids, 842129 may apply.
For parts, 842191 includes components for centrifuges, while 842199 covers parts for filtering machinery. Ensure you select the right code based on the specific machinery and its function to avoid customs issues.
