HTS heading 3604 is a broad product category for pyrotechnic and signaling articles. It groups items such as fireworks, signaling flares, rain rockets, fog signals, and other articles that produce light, sound, smoke, or a similar pyrotechnic effect. The heading covers the finished article, not merely the chemical ingredients used to make it.
To reach the correct 8-digit HTSUS code, first identify the article’s primary function and design—for example, entertainment fireworks, distress or signaling equipment, or another pyrotechnic device. The more detailed provisions may distinguish among product types, intended uses, and sometimes construction or composition. Read the full descriptions at the 8-digit level and confirm that the product’s physical characteristics and intended use match the wording, rather than selecting a code based only on a marketing name.
What to check
- Obtain the product’s technical description, instructions, photographs, and safety or transportation documentation before classifying it.
- Identify whether the article is intended primarily for display, signaling, fog production, or another pyrotechnic purpose.
- Check the complete HTSUS hierarchy from heading 3604 through the applicable 8-digit provision; do not stop at the 4-digit heading.
- Compare the product’s composition, ignition method, output, packaging, and intended use with the detailed subheading descriptions and relevant notes.
- Confirm the classification with a qualified customs broker or request a formal customs ruling when the product has unusual features or could fit more than one provision.
HTS heading 3604 summary
Fireworks is a 4-digit product category containing 1 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
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.
