[Operating Rate Significantly Falls, Producer Inventory Slightly Destocks, Circulation-End Inventory Continues to Accumulate] According to the survey, multiple primary magnesium smelters intensively entered a maintenance shutdown period this week, and the overall industry operating rate pulled back significantly. A magnesium plant in Shanxi completed commissioning and produced magnesium ingots last week, but the overall scale of production cuts in the industry far exceeded the contribution from new capacity, and total primary magnesium production maintained a downward trend. In this round, the enterprises under centralized maintenance in Shaanxi plan to resume production mostly in mid-to-late July, while some producers indicated that the resumption period would be flexibly adjusted according to magnesium prices. It is expected that China's primary magnesium output will continue to contract next week.

Production and Inventory Brief

1.1 Weekly Production

From July 3 to July 9, the weekly production of sample magnesium plants nationwide stood at 23,419 mt, and the weekly operating rate was 76.83%, down 7.41% WoW. According to the survey, multiple primary magnesium smelters entered a concentrated period of maintenance shutdowns this week, causing the overall industry operating rate to pull back significantly. A magnesium plant in Shanxi completed commissioning and produced magnesium ingot last week, but overall industry production cuts far exceeded the contribution from new capacity, keeping total primary magnesium production on a downward trend. The smelters in Shaanxi undergoing centralized maintenance plan to resume production mostly in mid to late July. Meanwhile, some producers indicated that the restart timing would be flexibly adjusted based on magnesium price movements. Next week, domestic primary magnesium production is expected to continue contracting.

1.1 Weekly Inventory

1. Producer inventories edged down 0.95% WoW this week, and China's magnesium ingot social inventory pulled back slightly. Multiple smelters in major production areas underwent centralized maintenance shutdowns, and the tightening of overall market supply supported destocking. However, regional divergence was notable: in Fugu, only a few enterprises actively cleared inventory and sold, causing factory inventories in Shaanxi to continue building; in contrast, Ningxia magnesium producers showed a strong willingness to sell, and local producer inventories dropped significantly, creating a stark contrast between the two regions' inventory trends.

2. Social inventory rose 3.8% WoW this week, showing a slight buildup. By region, inventories in Shaanxi, Shanxi, and at Tianjin port all accumulated to varying degrees. In Shaanxi, speculative sentiment strengthened somewhat, with some traders buying small amounts on dips to stockpile and wait for future market developments. In Shanxi, purchased goods from some traders gradually flowed into warehouses. At Tianjin port, export orders remained sluggish, and with deliveries not yet due, export destocking was hindered, resulting in inventory buildup. Overall, the digestion of circulating goods was slow, and inventory pressure may persist.

Magnesium Inventories Decline as Smelters Shut Down for Maintenance, Regional Disparities Evident

[SMM Weekly Magnesium Inventory Flash Report] This week, manufacturers' inventory decreased slightly by 0.95% compared to the previous week, and the domestic social inventory of magnesium ingots also declined slightly. Multiple smelters in the main production areas have concentrated on shutdown for maintenance, and the contraction of overall market supply has supported inventory reduction; however, regional differentiation is significant. Only a few enterprises in Fugu have actively cleared inventory and shipped goods, driving continuous accumulation of factory inventory in the Shaanxi region; in contrast, magnesium enterprises in Ningxia have a strong willingness to ship goods, with a prominent decline in local manufacturers' inventory, forming a sharp contrast in inventory trends between the two regions.

Magnesium Production Declines 7.41% MoM as Plants Enter Maintenance Cycle, Output Expected to Further Contract

[SMM Weekly Magnesium Production Flash Report] From July 3 to July 9, the weekly production of the national sample magnesium plants was 23,419 tons, with a weekly operating rate of 76.83%, down 7.41% month-on-month. According to the survey, this week, multiple primary magnesium smelting enterprises have entered the shutdown and maintenance cycle, and the overall operating rate of the industry has significantly declined. A magnesium plant in Shanxi completed production and produced magnesium ingots last week, but the overall production reduction scale of the industry far exceeded the contribution of new production capacity, and the total production of primary magnesium continued to decline.
