HS Code for Nickel oxide sinter

Nickel oxide sinter is classified under HS code 7501.20. While nickel oxides as pure chemicals fall under Chapter 28, nickel oxide sinters are considered intermediate products of nickel metallurgy and are thus placed in Chapter 75. Heading 7501 covers nickel mattes and oxide sinters. Sintering is a process where nickel oxide is heated to form a solid mass without melting it to the point of liquefaction, typically for use in the production of alloy steels. The classification 7501.20 is specific to these metallurgical intermediates that contain varying levels of impurities compared to the chemically pure oxides of 2825.40. The Harmonized System distinguishes these based on their intended use in the metallurgical industry and their physical state as sintered aggregates.

Products Included

• Sintered nickel oxide
• Green nickel oxide (metallurgical grade)
• Nickel oxide sinters for steel alloying
• Intermediate nickel oxide metallurgical products

Common Misclassification

Nickel oxide sinter is frequently misclassified under HS code 2825.40, which is reserved for pure chemical nickel oxides. The distinction is based on the metallurgical nature of the sinter. It may also be confused with unwrought nickel in 7502.10, but sinters are still considered intermediate products because they are oxides, not the metallic form of nickel. Proper classification depends on identifying the sintering process in the manufacturing history.

FAQ

What is the HS code for nickel oxide sinter?

The HS code for nickel oxide sinters and other intermediate products of nickel metallurgy is 7501.20.

Why is nickel oxide sinter in Chapter 75 instead of Chapter 28?

It is placed in Chapter 75 because it is a metallurgical intermediate product rather than a separate, chemically defined inorganic compound, which is the requirement for Chapter 28.
