Dear Users,
To further enhance the accuracy and consistency of our data, our company has adjusted the calculation methodology for the tin import profit margin indicator:
I. Reason for Adjustment
Based on current import practices, imported tin ingots with certificates of origin are exempt from the 3% tariff, with the actual applicable tariff rate being zero. In line with current market import practices, all imported tin ingots are subject to a zero tariff rate.
Therefore, our company has adjusted the tariff parameter in the tin import profit margin calculation, changing the original tariff parameter from 3% to zero, to more accurately reflect actual import costs and profit margin conditions.
II. Scope of Impact
This adjustment involves the tin import profit margin indicator data displayed on https://hq.smm.cn/data/ and in Data-Pro.
Upon completion of the adjustment, the tin import profit margin indicator data will be uniformly recalculated and displayed based on the new methodology.
III. Effective Date
This data adjustment takes effect on April 27, 2026.
We sincerely apologize for any inconvenience this adjustment may cause. Thank you for your continued support and understanding of our data services.
