(3) Items of replacement (company material (COMAT)) for hazardous materials described in paragraph (a)(2) of this section must be transported in accordance with this subchapter. When an operator transports its own replacement items described in paragraph (a)(2), the following exceptions apply:

(4) Unless otherwise addressed by FAA regulation or policy (e.g. Advisory Circular), hazardous materials used by the operator aboard the aircraft, when approved by the Administrator of the Federal Aviation Administration.

(1) Oxygen, or any hazardous material used for the generation of oxygen, for medical use by a passenger, which is furnished by the aircraft operator in accordance with 14 CFR 121.574, 125.219, or 135.91. For the purposes of this paragraph (b)(1), an aircraft operator that does not hold a certificate under 14 CFR parts 121, 125, or 135 may apply this exception in conformance with 14 CFR 121.574, 125.219, or 135.91 in the same manner as required for a certificate holder. See § 175.501 for additional requirements applicable to the stowage of oxygen.

(2) Dry ice (carbon dioxide, solid) intended for use by the operator in food and beverage service aboard the aircraft.

(3) Aerosols of Division 2.2 only (for dispensing of food products), alcoholic beverages, colognes, liquefied gas lighters, perfumes, and portable electronic devices containing lithium cells or batteries that meet the requirements of § 175.10(a)(18) carried aboard a passenger-carrying aircraft by the operator for use or sale on that specific aircraft. A liquefied gas lighter design must be examined and successfully tested by a person or agency authorized by the Associate Administrator.

(4) A tire assembly with a serviceable tire, provided the tire is not inflated to a gauge pressure exceeding the maximum rated pressure for that tire, and the tire (including valve assemblies) is protected from damage during transport. A tire or tire assembly which is unserviceable or damaged is forbidden from air transport;  however, a damaged tire is not subject to the requirements of this subchapter if it contains no material meeting the definition of a hazardous material (e.g., Division 2.2).
