Angola is a Southern African nation whose varied terrain encompasses tropical Atlantic beaches, a labyrinthine system of rivers and Sub-Saharan desert that extends across the border into Namibia.
CNCA or CTN in English, is a requirement implemented by the Angola Customs Officials in 1994.
Angola is one of the first countries to implement this new requirement, and it is going on since.
The CNCA is obligatory for all ports in Angola, such as Luanda and Lobito ports.
CNCA stands for Conselho Nacional de Carregadores de Angola.
