The exporter must receive a certificate from his national government on Form D stating that the goods have met the 40% requirement. Form D must be submitted to the customs authority of the importing government in order to benefit from the CEPT rate.

These difficulties are due to the fact that each ASEAN national customs authority processes and implements the requirements of Form D without much coordination.

The EU also funds regional trade projects such as: ASEAN members have the option of excluding CEPT products in three cases: 1) Temporary exclusions 2.) Sensitive agricultural products 3.)
