DEFINITION

Classification: 60/39.823

Pyrotechnic squib or charge type:

(under subclass 39.821) Combustion devices wherein the ignition device comprises structure composed of explosive-type materials but which has been modified or designed to burn rather than to explode.

(1) Note. The devices of this subclass are very similar to common fireworks and in particular firecrackers which have been ruptured or otherwise modified to cause the device to burn rather than to explode as in normal operation.
