Authorized DOT Cylinder Retesters - U.S. and International

Persons authorized to retest DOT cylinders under 49 CFR 173.34 are listed in two formats. The first format lists the retesters sequentially by Identification Number. The second format lists each state's retesters alphabetically by city and company name. The retester identification number, the name and address, the classes of cylinders authorized for retest, the date of the most recent authorization and current status of the retester is provided in both formats.
