Another term for Competent Authority is "Appropriate authority" which is used in the International Civil Aviation Organization's (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air. The Associate Administrator is the United States Competent Authority for purposes of 49 CFR part 107.
Competent Authority Approval means an approval by the competent authority that is required under an international standard (for example, the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air and the International Maritime Dangerous Goods Code).

The term includes hazardous substances, hazardous wastes, marine pollutants, elevated temperature materials, materials designated as hazardous in the Hazardous Materials Table (see 49 CFR 172.101 ), and materials that meet the defining criteria for hazard classes and divisions in part 173 of subchapter C of this chapter.

Person means an individual, firm, copartnership, corporation, company, association, or joint-stock association (including any trustee, receiver, assignee, or similar representative); or a government or Indian tribe (or an agency or instrumentality of any government or Indian tribe) that transports a hazardous material to further a commercial enterprise or offers a hazardous material for transportation in commerce.

Regulations issued under Federal hazardous material transportation law include this subchapter A (parts 105-110) and subchapter C (parts 171-180) of this chapter, certain regulations in chapter I (United States Coast Guard) of title 46, Code of Federal Regulations, and in chapters III (Federal Motor Carrier Safety Administration) and XII (Transportation Security Administration) of subtitle B of this title, as indicated by the authority citations therein.
Special permit means a document issued by the Associate Administrator, the Associate Administrator's designee, or as otherwise prescribed in the HMR, under the authority of 49 U.S.C. 5117 permitting a person to perform a function that is not otherwise permitted under subchapter A or C of this chapter, or other regulations issued under 49 U.S.C. 5101 et seq.

Waiver of Preemption means a decision by the Associate Administrator to forego preemption of a non-Federal requirement-that is, to allow a State, political subdivision or Indian tribe requirement to remain in effect. The non-Federal requirement must provide at least as much public protection as the Federal hazardous materials transportation law and the regulations issued under Federal hazardous materials transportation law, and may not unreasonably burden commerce.
