Certificate of Conformity or Inspection for Kenya/Nigeria

Question regarding: Certificate of Conformity or Inspection for Kenya/Nigeria

For a number of years now we have supplied goods to Nigeria and have always completed a SONCAP application for sea shipments. I am told that this is not applicable for air shipments by my agent? Is this true?

Further to that I now have a shipment bound for Kenya which is also bound by a similar inspection process, does the same rule apply. Air shipments do not need any inspection or do ALL shipments require thus process to take place?
