Dear Mr. Self: This is in reply to your letter of December 30, 1971, concernin whether you must comply with the Certification regulations (49 CFR Part 567) in cases where you 're-barrel' or 're-deck' trailers. You describe these processes as installing a new tank (re-barreling) or platform deck (re- decking) on a used trailer under construction furnished by your customer, which includes axles, tires, wheels, springs, hangers, and internal brake assemblies, in serviceable condition.; You are not required to certify these vehicles as they are manufacture on used chassis and are considered by this agency to be used vehicles under section 108(b)(1) of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. S 1397(b)(1)).; We are pleased to be of assistance. Sincerely, Richard B. Dyson, Assistant Chief Counsel
