The specifications of gold bars vary from country to country, but according to international practice, gold bars entering the market must be marked with their fineness and weight, as well as the name and number of the refinery when they are cast in the refinery.
Casting packaging of gold bars
Under normal circumstances, investors often buy gold bars produced by well-known refining companies, which will save a lot of expenses and procedures when selling them in the future. If it is produced by an unknown enterprise, the gold buyer will charge an analysis fee. The gold bars sold by internationally renowned gold merchants are all packed in sealed small bags.
In addition to containing gold, there are reliable seals as evidence. It will be much more convenient to sell gold bars without opening them. In China, the Great Wall Gold and Silver Refinery is by far the largest state-owned gold and silver refinery, the only member of London Precious Metals Market Association among China gold and silver smelters, and was elected as the Shanghai Gold Exchange and the governing unit.
