HS Code for Signal flares

Signal flares are classified under HS code 3604.90. This classification falls within Chapter 36, which covers explosives, pyrotechnic products, pyrophoric alloys, and certain combustible preparations. Heading 3604 specifically includes fireworks, signalling flares, rain rockets, fog signals, and other pyrotechnic articles. While fireworks are categorized under 3604.10, all other pyrotechnic signaling devices are grouped under the residual subheading 3604.90. These products are defined by their use of exothermic chemical reactions to produce light, smoke, or sound for signaling purposes, particularly in maritime, aviation, or emergency contexts. The classification is based on the pyrotechnic nature of the device; it must contain a chemical composition that is ignited to perform its signaling function. This code is essential for ensuring that hazardous materials are handled according to safety standards for explosive and flammable goods during transport and storage.

Products Included

• Handheld distress flares
• Parachute flares for maritime use
• Smoke signals (pyrotechnic)
• Aerial signal rockets
• Fog signals (pyrotechnic)

Common Misclassification

Signal flares are most commonly misclassified under 3604.10, which is strictly for fireworks intended for entertainment. They may also be confused with 9306.90 (munitions of war) if they are military-grade, but 3604.90 is the standard classification for civilian and commercial signaling devices. Another significant error is classifying electronic LED flares under this code; electronic signaling devices do not contain pyrotechnic material and should be classified under Chapter 85, typically 8531.80, as electrical sound or visual signaling apparatus.

FAQ

What is the HS code for signal flares?

The HS code for pyrotechnic signal flares is 3604.90.

Are maritime emergency flares included in this code?

Yes, maritime distress signals, including handheld flares and parachute rockets, are classified under 3604.90 because they rely on a pyrotechnic charge to function.
