HS Code for Catalytic preparations
Catalytic preparations are classified under HS code 3815.90. This classification falls within Chapter 38, which covers miscellaneous chemical products. Heading 3815 is dedicated to reaction initiators, reaction accelerators, and catalytic preparations that are not elsewhere specified or included. The subheading 3815.90 is a residual category for "other" catalysts that are not "supported" catalysts. Supported catalysts (those consisting of active substances deposited on a carrier like silica or alumina) are classified under subheadings 3815.11 through 3815.19. Therefore, 3815.90 is used for unsupported catalytic preparations, such as mixtures based on compounds of cobalt, magnesium, or organic peroxides used as polymerization initiators. The classification is determined by the chemical nature of the product and its role in facilitating a chemical reaction without being consumed in the process. This follows GRI 1, as the product is a chemical preparation specifically described by the text of heading 3815.
Products Included
- Unsupported chemical catalysts
- Organic peroxide preparations used as initiators
- Mixed catalysts not on a support
- Polymerization accelerators for plastics manufacturing
- Redox catalysts for industrial chemical synthesis
Common Misclassification
Catalytic preparations are often confused with 3815.11 or 3815.19. The distinction lies in the presence of a support (a carrier). If the catalyst is coated onto a substrate, it must be classified under the 3815.1x series. Additionally, pure precious metals used as catalysts are classified in Chapter 71, and chemically defined compounds are often classified in Chapter 28 or 29 unless they are specifically prepared as catalysts.
FAQ
