Do we need to apply for Accreditation even if we will not import the parts & components of used trucks and buses which we will use for rebuilding?

As per DTI Department Administrative Order (DAO) 08, Series of 2003, all establishments, which conduct or provide rebuilding services for trucks falling under any of the following categories: M3, N1, N2 or N3 of PNS:1891:2000, must be accredited first by the DTI before they can legally engage in the business of truck rebuilding.
