Reaction initiators, reaction accelerators and catalytic preparations, not elsewhere specified or included
8 declarable lines
Heading 3815 covers reaction initiators, reaction accelerators and catalytic preparations that are not classified elsewhere. It is split first between supported catalysts, which carry the catalyst on a carrier, and all other preparations. Supported catalysts are divided by active substance: nickel, precious metals with a separate line for platinum group metals, and other. The residual group is divided between preparations wholly of inorganic substances, by the specific element, and all other preparations.
Products in this heading

How to choose the right subheading
- Whether the catalyst is supported on a carrier or is unsupported, which decides between 3815.11 through 3815.19 and 3815.90.
- For supported catalysts, the active substance: nickel or nickel compounds, precious metals, or other.
- For precious metal catalysts, whether the active substance is a platinum group metal.
- For other preparations, whether the product consists wholly of inorganic substances.
- For wholly inorganic products, the specific element present, such as bismuth, tungsten, vanadium, mercury or molybdenum.
Often confused with
- Heading 3812Prepared rubber accelerators
Rubber accelerators and compound stabilizers have their own heading.
- Heading 3811Antiknock preparations and oxidation inhibitors for fuels
Prepared additives for mineral oils are classified in 3811.
- Heading 3808Disinfectants and similar preparations put up for retail sale
Insecticides, fungicides and disinfectants go to 3808.
- Heading 3809Finishing agents and dye carriers for textiles
Textile, paper and leather finishing preparations are in 3809.
- Heading 3824Chemical preparations not elsewhere specified
Mixtures that are not catalysts or initiators fall in the residual chemical heading.
Frequently asked questions
What is the HTS code for a nickel hydrogenation catalyst?
Supported catalysts with nickel or nickel compounds as the active substance are classified under 3815.11.00.00, with a general (MFN) rate of Free.
What is the duty on a supported platinum group metal catalyst?
Supported catalysts with platinum group metals as the active substance are classified under 3815.12.00.10, with a general (MFN) rate of Free. Supported precious metal catalysts that are not platinum group metals use 3815.12.00.90, also Free.
How do I classify a bismuth or vanadium based catalyst?
A preparation consisting wholly of inorganic substances based on bismuth, tungsten or vanadium is classified under 3815.90.10.00, with a general (MFN) rate of 6.5%. Other wholly inorganic preparations fall under 3815.90.30.00, which is Free.
