Dear Valued Client,
To keep pace with the rapid development of the secondary copper industry and meet the market's need for in-depth analysis of the recycling industry and the supply-demand pattern of copper cathode, our company has conducted a deep optimization of our data models. We are now systematically upgrading and adjusting the standards and content of monthly supply-demand balance data related to China's copper scrap, with the following treatment applied to historical data:
I. Adjustments Made
The following data points have been newly launched:
"Copper Scrap New and Old Scrap Production: Domestic Old Scrap: Annual", "Copper Scrap New and Old Scrap Production: Domestic New Scrap: Annual", "Copper Scrap New and Old Scrap Production: Domestic Copper Scrap: Annual", "Copper Scrap New and Old Scrap Production: Domestic Old Scrap - Forecast: Annual", "Copper Scrap New and Old Scrap Production: Domestic New Scrap - Forecast: Annual", and "Copper Scrap New and Old Scrap Production: Domestic Copper Scrap - Forecast: Annual"—a total of six new data points. (Access path for new data: Database - Copper - Copper Scrap - Production - Domestic Copper Scrap Production)
II. Historical Data Processing
The following four historical data series will cease to be updated starting from December 2025: "Domestic Copper Scrap Supply (Metal Content), ID: a10031747", "SMM Domestic Copper Scrap Supply: YoY, ID: a10031748", "Domestic Copper Scrap Supply (Metal Content) - Forecast, ID: a12731971", and "SMM Domestic Copper Scrap Supply YoY - Forecast, ID: a12731972". Going forward, the new standards will be uniformly applied for data releases, with the revised data traceable back to 2020. Should you have any questions, please feel free to contact the SMM customer service team at any time. Thank you for your continued support and trust!
