Import customs clearing / rules / recommendations

We are currently building a small guesthouse/hotel on the South Coast, and while we, out of principle, are trying to source as much as possible locally, we need to import some finishing details. However, we are finding it very difficult to get information on the current COVID import restrictions. Does anyone know of custom clearing agents or have any information or advice on how to go about it?  We find it difficult to get information from the bigger customs clearing houses as we are not doing full container loads, and the import is just for our build. All advice and reccos appreciated  🙂
