Delivering CoCs with a digital signature

To show that the data on the digital Certificate of Conformity (CoC) has not been changed during transport and storage and has originated from the correct party, RDW requires the digital signature of the manufacturer or the manufacturer’s representative.

Because manufacturers have said they are finding it difficult delivering the digital signature exactly according to the specifications, digital CoCs without a digital signature may be delivered until 1 January 2023. In the future, however, the digital signature will be mandatory.

Audit report

Up to 1 January 2023, importers may deliver digital CoCs without the manufacturer’s digital signature. If digital CoCs are delivered without the manufacturer’s digital signature, importers must issue an assurance report every year. RDW will monitor the entire process on the basis of this report. In an assurance report, an independent auditor will certify that the CoCs delivered to RDW correspond with the CoCs compiled by the manufacturers.

Overview of the various options

  • Manufacturers that deliver CoCs directly to RDW may do so with/without a digital signature. 
  • Manufacturers that deliver CoCs through a provider may only do so if the CoC includes a digital signature. 
  • Importers that deliver CoCs directly to RDW may do so with/without a digital signature; however, one extra requirement is that an assurance report must also be supplied.
  • Importers that deliver CoCs to RDW through a provider may do so with/without a digital signature; however, one extra requirement is that an assurance report must also be supplied.
