Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
See which port, if it is from the border (Pingxiang, Dongxing port), will not be needed.
Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke
Strictly speaking, as long as there are solid wood packaging, you need to do fumigation inspection, proved not necessarily used, there are IPPC chapters on it.
