According to SMM, the current tight supply situation of secondary copper raw materials persists. Affected by the US tariff policy, the purchase willingness of US-origin traders is low, and the supply of US-origin materials is gradually decreasing. SMM expects that the imports of secondary copper raw materials will continue to decline in June, and the impact of the reduced supply of US-origin materials will become more pronounced in subsequent data, with its share possibly falling below 5%.
