View full HS code details

Fog signals are classified under HS code 3604.90, a category that covers pyrotechnic products used for signaling, safety, and other non-entertainment purposes. This heading is located within Chapter 36, which deals with explosives, pyrotechnic products, matches, and certain combustible preparations. Specifically, 3604.90 is a residual subheading for pyrotechnic articles other than fireworks, which are separately classified under 3604.10. Fog signals are critical safety devices used in maritime, railway, and aviation industries to provide audible or visual warnings in conditions of low visibility, such as heavy fog or darkness. These devices operate on pyrotechnic principles, meaning they contain chemical compositions designed to produce a specific effect—such as a loud report, a bright flare, or a dense smoke cloud—through a self-sustaining exothermic chemical reaction. The classification is strictly based on the pyrotechnic nature of the device. If a signaling device uses electronic components to produce sound or light, it would be classified elsewhere. The inclusion of fog signals in Chapter 36 highlights their status as regulated articles containing energetic materials, requiring specific handling and safety protocols during international trade and transport.

Products Included

Common Misclassification

Fog signals are often misclassified under HS code 8531.80, which covers electric sound or visual signaling apparatus. The key difference is the source of the signal; 8531 is for electronic devices like sirens or strobe lights, whereas 3604.90 is for pyrotechnic devices. They may also be confused with 3603.00, which covers safety fuses or detonating fuses used to ignite explosives.
