Dear Valued Customers, Pursuant to the requirements of Announcement No. 10 of 2025 issued by the Ministry of Commerce (MOFCOM) and the General Administration of Customs (GAC) of China on February 4, 2025, Ammonium Paratungstate (APT) and Tungsten Oxide have been included in the list of export-controlled items. Export operators are required to apply for a license in accordance with the law before conducting related business. Affected by this policy, the export volume of domestic Ammonium Paratungstate (APT) and Tungsten Oxide products has dropped sharply, and the subsequent export scale will remain at a low level. Due to the significant decline in export transaction activity, the market price formation mechanism no longer has sufficient data support, and continuing to update price points can hardly reflect the real market situation. To ensure the accuracy and professionalism of our information services, after careful consideration, SMM has decided to cease updating the two price points of "APT FOB" and "Tungsten Oxide FOB" starting from October 9, 2025. During the suspension of updates, our company will continue to track the dynamic adjustments of export control policies and the changing trends of the global tungsten industry chain. If the market becomes active again and the price data becomes representative in the future, we will restart the price update service as soon as possible and announce it separately. The historical data of the above-mentioned price points that have ceased to be updated will continue to be retained in the SMM database. If you have any needs for historical data inquiry and related business consultation, please feel free to contact Liu Xiaolei at +86 15021973263 or Li Jiahui at +86 13792518717, lijiahui@smm.cn.
