Dear Users,
To optimize the data structure and enhance your data retrieval and analysis efficiency, we will make an adjustment to the classification hierarchy of "Rare Earth" data.
Comparison of Adjustment Details:
Before Adjustment

After Adjustment

Effective Date of Adjustment:
November 14, 2025
Reasons for Adjustment:
1. Significant Increase in Data Importance: As a critical strategic resource and the "vitamin" of modern industry, the depth, breadth, and value of rare earth-related data have become increasingly prominent. Elevating it to a first-level classification will more accurately reflect its core position in our data system.
2. Sustained Growth in User Attention: We have observed a substantial increase in the frequency of queries, depth of analysis, and overall attention to rare earth data in recent years. This adjustment aims to respond to your needs, making the classification structure more aligned with your usage habits and enabling easier and more intuitive access to relevant data.
3. Fundamental Differences in Category Nature: The application fields and market logic of the rare earth category are fundamentally different from those of the traditional "minor metal" category. To adhere to a more scientific and precise industrial classification standard, it has been separated from the "Minor & Precious Metals" category to avoid conceptual confusion.
Impact and Recommendations for You:
• Change in Data Access Path: After the adjustment, you can directly find the "Rare Earth" category under the first-level classification directory of the database, without needing to access it through the "Minor & Precious Metals" hierarchy.
• This adjustment will not result in any loss of historical data; it only changes the classification hierarchy.
We believe this adjustment will provide you with a clearer and more efficient data service experience. We sincerely apologize for any inconvenience this may cause and thank you for your understanding and support.
