I wish to supply approved road vehicle components to vehicle manufacturers. Can I convert my CRNs and SARNs into CTAs?
If you hold or have held a CRN (Component Registration Number) or SARN (Sub-Assembly Registration Number) in the RVCS (Road Vehicle Certification System) and you wish to supply approved road vehicle components to vehicle manufacturers, you may choose to apply for a CTA under the RVS legislation. However, there will be circumstances where CRNs and SARNs can continue to be used for some RVS legislation approvals. More information HERE.
