Direct answer
Pyrotechnic special-effect material is a defined term in the International Fire Code (IFC) 2009, in Explosives and Fireworks. The code's own words are: “A chemical mixture used in the entertainment industry to produce visible or audible effects by combustion, defJagration or detonation. Such a chemical mixture predominantly consists of solids capable of producing a controlled, self-sustaining and self-contained exothermic chemical reaction that results in heat, gas sound, light or a combination of these effects. The chemical reaction functions …” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 2 chapters of this corpus, most often in Definitions (IFC 2009), Explosives and Fireworks (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

What does this term mean?
Pyrotechnic Special-effect Material — IFC 2009, Explosives and Fireworks:
A chemical mixture used in the entertainment industry to produce visible or audible effects by combustion, defJagration or detonation. Such a chemical mixture predominantly consists of solids capable of producing a controlled, self-sustaining and self-contained exothermic chemical reaction that results in heat, gas sound, light or a combination of these effects. The chemical reaction functions without external oxygen.
What must be verified before using this guidance?
Pyrotechnic Special-effect Material is defined once in this corpus, in the Explosives and Fireworks chapter of the International Fire Code (IFC) 2009:
A chemical mixture used in the entertainment industry to produce visible or audible effects by combustion, defJagration or detonation. Such a chemical mixture predominantly consists of solids capable of producing a controlled, self-sustaining and self-contained exothermic chemical reaction that results in heat, gas sound, light or a combination of these effects. The chemical reaction functions without external oxygen.
Where pyrotechnic special-effect material is used in the code
The term appears in 2 chapters of the 2009 I-Codes hosted here. The chapters that lean on it hardest are the ones to read next.

The terms pyrotechnic special-effect material is built out of
The definition above leans on 3 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what pyrotechnic special-effect material covers:
- Combustion — IRC 2009: In the context of this code, refers to the rapid oxidation of fuel accompanied by the production of heat or heat and light.
- Detonation — IBC 2009: An exothermic reaction characterized by the presence of a shock wave in the material which establishes and maintains the reaction.
- Chemical — IFC 2009: An element, chemical compound or mixture of elements or compounds or both.

Frequently asked questions
What is the code definition of pyrotechnic special-effect material?
The International Fire Code (IFC) 2009 defines it in Explosives and Fireworks as: “A chemical mixture used in the entertainment industry to produce visible or audible effects by combustion, defJagration or detonation. Such a chemical mixture predominantly consists of solids capable of producing a controlled, self-sustaining and self-contained exothermic chemical reaction that results in heat, gas sound, light or a combination of these effects. The chemical reaction functions without external oxygen.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.
Which parts of the code depend on pyrotechnic special-effect material?
In this corpus the term is used across 2 chapters, led by Definitions in the IFC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.
What is the HS code for fireworks?
Fireworks is a separate defined term. The IBC 2009 defines it as: “Any composition or device for the purpose of producing a visible or audible effect for entertainment purposes by combustion, deflagration or detonation that meets the definition of 1.4G fireworks or 1.3G fireworks as set forth herein.” That is not the same as pyrotechnic special-effect material, which the IFC 2009 defines as “A chemical mixture used in the entertainment industry to produce visible or audible effects by combustion, defJagration or detonation. Such a chemical mixture predominantly consists of solids capable of producing a controlled, self-sustaining and self-contained exothermic chemical reaction that results …” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
What is pyrotechnic equipment?
Equipment is a separate defined term. The IRC 2009 defines it as: “All piping, ducts, vents, control devices and other components of systems other than appliances that are permanently installed and integrated to provide control of environmental conditions for buildings. This definition shall also include other systems specifically regulated in this code.” That is not the same as pyrotechnic special-effect material, which the IFC 2009 defines as “A chemical mixture used in the entertainment industry to produce visible or audible effects by combustion, defJagration or detonation. Such a chemical mixture predominantly consists of solids capable of producing a controlled, self-sustaining and self-contained exothermic chemical reaction that results …” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
