About heading 3815

Reaction initiators, reaction accelerators and catalytic preparations, not elsewhere specified or included

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.

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.
