What are the advantages of transshipment of goods from Hong Kong?

The advantage of goods being re-exported from Hong Kong is that Hong Kong is a free trade port, if the goods are re-exported to Hong Kong; If the goods are not stipulated by the state, the export is basically tax-free, and there will even be tax rebate subsidies. As for whether the destination port can import duty-free, it depends on whether it belongs to a free trade zone, such as the bonded zone in China, and there are also such bonded zones in Singapore. Goods imported from abroad into the area are duty-free, and if they want to enter places outside the national bonded area, they must be taxed according to regulations.
