Direct answer
Dispensing is a defined term in the International Building Code (IBC) 2009, in Use and Occupancy Classification. The code's own words are: “The pouring or transferring of any material from a container, tank or similar vessel, whereby vapors, dusts, fumes, mists or gases are liberated to the atmosphere.” The IFC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 27 chapters of this corpus, most often in Motor Fuel-dispensing Facilities and Repair Garages (IFC 2009), Flammable and Combustible Liquids (IFC 2009), Hazardous Materials-general Provisions (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

The terms dispensing is built out of
The definition above leans on 2 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what dispensing covers:
- Container — IFC 2009: A vessel of 60 gallons (227 L) or less in capacity used for transporting or storing hazardous materials.
- Vessel — IFC 2009: A motorized watercraft, other than a seaplane on the water, used or capable of being used as a means of transportation.

Frequently asked questions
What is the code definition of dispensing?
The International Building Code (IBC) 2009 defines it in Use and Occupancy Classification as: “The pouring or transferring of any material from a container, tank or similar vessel, whereby vapors, dusts, fumes, mists or gases are liberated to the atmosphere.” 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 dispensing?
In this corpus the term is used across 27 chapters, led by Motor Fuel-dispensing Facilities and Repair Garages 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 definition of a building code?
Building is a separate defined term. The IBC 2009 defines it as: “Any structure used or intended for supporting or sheltering any use or occupancy.” That is not the same as dispensing, which the IBC 2009 defines as “The pouring or transferring of any material from a container, tank or similar vessel, whereby vapors, dusts, fumes, mists or gases are liberated to the atmosphere.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
