Which Aerosol Packaging Category is composed of approved thermoplastic materials such as PET, PEN, nylon, or a blend and has a maximum capacity not exceeding 500 mL?

• A. IP7
• B. IP7A
• C. IP7B
• D. IP7C

Answer: (D)

The key idea is how aerosol packaging is classified by both the material of the container and its size. This category specifies that the container is made from approved thermoplastic materials—such as PET, PEN, nylon, or a blend—and that the maximum capacity does not exceed 500 mL. Because the description exactly matches both the permitted plastics and the 500 mL limit, it fits this aerosol packaging category precisely. Other categories cover different materials or larger capacities, so they wouldn’t apply here. This approach helps ensure safe air transport by controlling what the container is made of and how much contents it can hold.
