Report Information - Report Title: Zinc Industry Weekly Report - Report Date: June 3, 2025 [1] Core Viewpoints Bullish Factors - Global zinc sheet supply shortage, with a cumulative shortage of 101,600 tons from January to March, and inventory continuously decreasing [3] - Decrease in zinc inventories in LME and SHFE, and basis premium supports prices [3] Bearish Factors - Rebound in imported zinc concentrate TC combined with refinery restart, strengthening the expectation of supply surplus [3] - Consumption enters the traditional off - season, galvanized demand weakens, and downstream procurement is sluggish [3] Trading Consultation Viewpoint - The SHFE zinc ZN2507 contract will maintain short - term oscillatory consolidation, with fundamental bullish and bearish factors intertwined [3] Summary by Catalog Processing and Terminal Demand - Include data on galvanized sheet coils (market sentiment index, weekly inventory, and steel mill weekly output), galvanized sheet (strip) net export, die - cast zinc alloy net import, real estate development investment, engineering progress, sales area, and land transaction area, and infrastructure fixed - asset investment [5][6][11][12][13][14][15][17][18] Futures and Spot Market Review - Include data on internal and external zinc price trends, LME term structure, zinc ingot basis trends [21][23][27] Supply and Supply - side Profits - Include data on zinc concentrate imports, processing fees, zinc ingot production, enterprise production profits, raw material inventory days, and zinc inventories in LME and SHFE [31][33][34][36][37][39]

Core View Positive Factors - Social inventory decreased by 0.25 million tons compared to last week. Downstream restocking at low prices drove the spot premium to remain stable, providing temporary support for demand [3]. - The spot price increased by 0.72% daily, and the basis premium widened to 138 yuan/ton, indicating a strong spot market [3]. Negative Factors - Mine supply is gradually recovering, with sufficient import volumes, and the market remains in an oversupply situation [3]. - Smelting profits are substantial, supply remains high, and there is an expectation of weakening demand in the medium term [3]. Trading Consultation View - It is difficult for the industry to reduce inventory. Furnace restarts in the southwest region may exacerbate the oversupply. It is recommended to maintain a short - allocation strategy [3]. Processing and Terminal Demand - The report presents data on the market sentiment index, inventory, and weekly production of galvanized coils, as well as the net export seasonality of galvanized sheets (strips) and die - cast zinc alloys. It also includes data on real estate development investment, sales, land transactions, and infrastructure fixed - asset investment [5][6][11][13][15][16]. Futures and Spot Market Review - The report shows the price trends of domestic and foreign zinc, the trading volume and open interest of SHFE zinc futures, the relationship between LME zinc prices and the US dollar index, the LME term structure, and the basis trends of zinc ingots in three locations [20][21][23][26]. Supply and Supply - Side Profits - The report provides data on the monthly import volume of zinc concentrates, zinc concentrate TC, zinc ingot production, enterprise production profits, raw material inventory days, and zinc inventory in LME and SHFE [30][32][33][35].

Report Information - Report Title: Zinc Industry Weekly Report - Report Date: May 19, 2025 [1] - Author: Xu Liang (Z0002220) - Reviewer: Tang Yun (Z0002422) Investment Rating - No investment rating information is provided in the report. Core Views Bullish Factors - High spot premiums are maintained, and refineries' reluctance to sell has led to a shortage of circulating supplies, supporting zinc prices [3]. - The US economic recovery and demand growth have exceeded expectations, and the easing of China-US tariffs has boosted market sentiment [3]. Bearish Factors - Domestic zinc smelters have strong production momentum, and the smooth resumption of overseas projects has increased supply-side pressure [3]. - Imported zinc ingots are arriving at ports, causing spot premiums to weaken. Weak demand during the off-season has suppressed prices [3]. Trading Advisory View - The fundamentals of the domestic zinc market provide limited support. The growth in supply and off-season demand are in a tug-of-war, and the market may maintain a volatile pattern in the short term [3]. Section Summaries Processing and End-User Demand - The report presents various data on the zinc processing and end-user demand sectors, including the market sentiment index, inventory, production, and trade data of galvanized steel coils, galvanized sheets (strips), die-cast zinc alloys, and other products.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the given reports. 2. Core Views Copper - The copper market presents a combination of "strong current situation + weak expectation". The short - term price is likely to fluctuate. The main contract price is expected to range between 77,500 - 79,500 yuan/ton. The macro - level factors and the uncertainty of demand in the peak season are the main influencing factors [1]. Aluminum - For alumina, the market is influenced by both positive and negative factors, and the price is expected to fluctuate in the short term. For electrolytic aluminum, the inventory reduction and the easing of tariff sentiment support the price, but the expected weakening of demand and the decline in cost put pressure on the price. The short - term price is likely to fluctuate [3]. Zinc - The short - term zinc price may be supported by the easing of tariff signals. In the future, the price may decline if terminal consumption is insufficient due to tariff policies, or maintain a high - level oscillation if the growth rate of the mining end is lower than expected and downstream consumption exceeds expectations. In the medium - to - long - term, a short - selling strategy is recommended, with the main contract price reference range of 21,500 - 23,500 yuan/ton [4]. Tin - The macro - sentiment improvement may drive the tin price to rebound, but considering the supply - side restoration and the pessimistic demand expectation, short - selling can be attempted in the range of 265,000 - 270,000 yuan/ton. Attention should be paid to the supply - side raw material restoration rhythm [7]. Nickel - The short - term nickel price is expected to fluctuate. The macro - sentiment has improved, and the cost provides some support, but the medium - term supply is expected to be loose. The main contract price is expected to range between 122,000 - 128,000 yuan/ton [8]. Stainless Steel - The stainless - steel market is expected to fluctuate. The raw - material end provides some support, but the short - term supply - demand contradiction has intensified, and the inventory pressure has slightly eased. The main contract price is expected to range between 12,600 - 13,200 yuan/ton [11]. Lithium Carbonate - The short - term lithium carbonate price is expected to show a weak oscillation. The supply pressure is obvious, the demand is relatively flat, and the inventory is still high. The main contract price is expected to range between 62,000 - 66,000 yuan/ton [14]. 3.

1. Report Industry Investment Ratings - Nickel - Rolling short [1] - Stainless steel - Wait - and - see [1] - Zinc - Bearish outlook [5] 2. Core Views - **Nickel and Stainless Steel**: The rumor of the Philippine nickel ore ban has been falsified, and the logic returns to the fundamentals. There is still an excess pressure in the nickel market, and it is recommended to roll short between 120,000 - 127,000 [1][2]. - **Zinc**: The impact of tariffs has temporarily subsided. In the short - term, supply is stable with a slight increase, while the peak demand season has passed. Manufacturers are pessimistic about terminal demand, so it is overall bearish [3][4]. 3. Summary by Relevant Catalogs **Nickel and Stainless Steel** - **Macro & Industry News**: In April 2025, China's nickel plate production was 33,120 tons, a month - on - month decrease of 2.1% and a year - on - year increase of 6.9%. The production of nickel sulfate was 29,600 tons, a month - on - month decrease of 12.9% and a year - on - year decrease of 17.8% [1]. - **Supply**: The rumor of the Philippine nickel ore ban is falsified. The mining end is likely to turn looser. The overall supply of domestic electrolytic nickel has shrunk month - on - month but remains at the highest level in the same period in history. The production cost of electrowinning nickel is expected to decline [1]. - **Demand**: In the process of producing nickel sulfate from nickel beans, the nickel cost is about 127,000 yuan. The demand support from downstream nickel sulfate cost is about 134,000 yuan/ton, and the profit critical point of external procurement manufacturers is about 137,000 yuan/ton. The possibility of stainless steel production cuts is small [2]. **Zinc** - **Macro & Industry News**: In April 2025, the retail sales of the national passenger car market were 1.755 million vehicles, a year - on - year increase of 14.5% and a month - on - month decrease of 9.4%. The cumulative retail sales this year were 6.872 million vehicles, a year - on - year increase of 7.9% [3]. - **Supply**: Although the profits of mining enterprises have shrunk, the TC price has not declined, indicating no production cuts at the mining end. The supply side generally shows a loosening trend, and the possibility of production cuts for both smelting and integrated enterprises is extremely small [3]. - **Demand**: The peak demand season is approaching the end. The production enthusiasm of galvanizing, die - casting alloy, and zinc oxide manufacturers is low, and the terminal demand is expected to decline [4].

1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views of the Reports Tin - The current supply of tin ore remains tight, but the supply is expected to recover in July. The demand improvement is limited, and the subsequent demand outlook is pessimistic. The Sino - US tariff negotiation consensus may drive the price to rebound, but considering supply recovery and weak demand, try shorting in the 265,000 - 270,000 range and focus on the supply recovery rhythm [1]. Copper - Macroeconomic factors such as tariffs and the "232" investigation affect copper prices. The supply of raw materials is tight, and domestic inventories are low. The demand in the peak season may not be sustainable. The copper market shows a "strong current + weak expectation" pattern, with prices expected to be volatile in the short - term, and focus on the demand after May and tariff negotiation progress [2]. Aluminum - For alumina, the operating capacity may fluctuate, demand is stable with limited growth, and the cost support is weakening. Prices are expected to be volatile. For electrolytic aluminum, the supply is stable, demand may decline, but the low inventory and tariff relaxation support the price. Overall, the price is expected to be weak, with a support range of 18,000 - 18,500 [4]. Zinc - The supply of zinc ore is loose. Refined zinc supply was affected by over - expected maintenance in April. Downstream demand is weak, and the purchasing index is weakening. Short - term prices may be supported by tariff relaxation. In the long - term, consider shorting, and focus on ore production and downstream demand changes [6]. Lithium Carbonate - The futures market fluctuates. The tariff negotiation result has a short - term impact on sentiment. The supply pressure is clear, demand is relatively flat, and inventory is high. Prices may stabilize in the short - term, but the upside is limited. The overall strategy is to short on rallies, with a reference range of 62,000 - 66,000 [9]. Nickel - The nickel market is affected by the rumored Philippine ore ban and tariff negotiation results. The cost support is strong, but the medium - term supply is loose, restricting the upside. The price is expected to be in a range - bound adjustment, with a reference range of 122,000 - 128,000 [11]. Stainless Steel - The stainless - steel market is affected by tariff negotiation results. The ore price provides support, but the supply is excessive, and demand is slowly recovering. The inventory pressure eases slightly. The price is expected to be volatile, with a reference range of 12,600 - 13,200 [14]. 3.
