According to the Shanghai Customs, China imported 

an average of 3.77 million metric tons of refined copper 

each year between 2016 and 2020. The Shanghai 

Customs handled 2.39 million metric tons of these 

imports each year during this period, representing 

66.88% of the yearly total. From 2020, the Customs no 

longer conducts statistics based on different customs 

gates.

China’s major bonded storage facilities for copper are 

located in Shanghai, Guangdong, Jiangsu, Fujian, and 

Tianjin. Starting from 2016, facilities outside Shanghai 

began to record inventories, totaling around 10,000 

to 30,000 metric tons, and except for small amount of 

import, these inventories were mostly export products 

under processing trade contracts. According to the 

statistics of Shanghai Mysteel Group, from 2013 to 

2020, copper inventory in Shanghai-based bonded 

storage facilities was as high as 1.01 million metric tons 

and as low as 181,000 metric tons.
