HTS heading 8424 is a broad product category for mechanical equipment that projects, disperses, or sprays a liquid or powder. It includes items such as fire extinguishers, spray guns, irrigation or spraying equipment, and steam-, sand-, or other jet-projecting machines, along with qualifying parts. The heading generally focuses on the appliance’s function and mechanical operation, not simply on the material it is made from.
To reach the correct 8-digit HTSUS code, first identify the article’s specific type and principal function, then review the subheadings and statistical provisions under heading 8424. The lower-level descriptions may distinguish equipment by design, use, capacity, operation, or whether it is a complete appliance or a part; material can also matter where the tariff text expressly creates a material-based distinction. Confirm that the item belongs in heading 8424 rather than a more specific heading, and apply the General Rules of Interpretation and relevant legal notes when needed.
What to check
- Describe what the product does, how it operates, and what it projects before searching for a code.
- Separate complete appliances from replacement or component parts, and check whether the part is specifically covered in heading 8424.
- Read every subheading and statistical suffix under 8424; do not choose a code based only on a product name or material.
- Check technical specifications such as pressure, capacity, nozzle or gun design, power source, and intended use when the tariff descriptions distinguish among types.
- Verify the current HTSUS text and obtain customs-broker or binding-ruling guidance when competing classifications remain plausible.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
