Vietnamese customs treat an accompanied consignment as an import like any other. The commercial invoice has to describe the goods in a way that supports the tariff line, the consignee has to be a company that can actually receive and clear, and duty and tax treatment should be settled before the courier flies rather than negotiated afterwards.
The variable that most often changes the answer is the receiving plant's own customs status. Export-processing enterprises, bonded facilities and ordinary importers are treated differently, sometimes very differently, and a consignment for one is not the same job as a consignment for another even when the goods are identical. That is why we ask who the consignee is before we quote.
Repair-and-return and equipment going in for testing or demonstration belong under a temporary admission regime rather than as an outright import. It is materially cheaper and it avoids an argument about getting the item out again.
Anything of plant or animal origin brings phytosanitary or veterinary requirements, and they are enforced. We raise that at the first conversation rather than the last.
