This heading covers pyrotechnic articles capable of producing luminous, acoustic, gaseous, smoke-producing or incendiary effects, including :
(1) Pyrotechnic articles for amusement : (a) Fireworks (bombs, fuses, maroons, jets, candles, luminous torches, Bengal matches and lights, etc.) the purpose of which is to provide entertainment through the acoustic, luminous or smoke-producing effects of their combustion. Firing is ensured by a firing powder, such as black powder, integrated into the article and fired by an electric fuse head or a primer fuse. (b) Pyrotechnic toys, such as caps for toy pistols (prepared in tapes, sheets, rolls or circular plastic rings), magic candles, and snaps for Christmas crackers. The combustion of these pyrotechnic toys causes only limited effects. (2) Technical devices : (a) Sound or light signalling devices, such as distress rockets for use at sea, photo-flash cartridges for the equipment of aircraft, Very flares, fog signals and torches for railways, individual distress rockets, lighting effects for cinema or television, etc., lighting devices, guide devices, pyrotechnic decoys, and smoke-producing devices (possibly coloured). Their general property is to produce a relatively long-lasting effect by light, sound or smoke. (b) Devices for agricultural or industrial use, such as anti-hail rockets, anti-hail cartridges, agricultural smoke-producers, thunder-flashes to scare animals, and smoke-producing devices to test for leaks in pipelines.
This heading also includes other pyrotechnic devices not specified in the previous groups (e.g., life-line rockets, lead-coated detonating cord for cutting and not for transmitting a detonation). The heading does not include : (a) Photographic flashlight materials (heading 37.07). (b) Articles producing a lighting effect by the phenomenon of chemiluminescence (heading 38.24). (c) Blank cartridges, containing an explosive charge, for riveting tools or for starting compression ignition internal combustion piston engines (heading 93.06).
