Hair spray and charcoal are given as example materials for which category in the AAMVA hazard class table?

49 CFR 172.101 (Hazardous Materials Table); AAMVA CDL Manual Section 4.2.1, Figure 4.1, p. 4-2

ORM-D materials are everyday consumer items that still carry some shipping restriction, even though they have no numbered hazard class. Drivers need to recognize that 'no number' doesn't mean 'no rule,' since the exam specifically tests this unnumbered-category distinction. Note: federal hazmat rules phased out the ORM-D marking in favor of 'Limited Quantity' starting in 2021, but the AAMVA manual this question draws from predates that change, and CDL knowledge-test content is built directly from the manual, so ORM-D terminology still appears on the exam.
