In 2023, China's re-import of worked slate, articles of slate, or agglomerated slate stood at approximately 32.8 thousand US dollars, marking the baseline for trend analysis. The forecasted data from 2024 to 2028 indicates a consistent year-on-year decline in value, with figures reducing from 32.02 thousand US dollars in 2024 to 28.66 thousand US dollars by 2028.
