〔Day Digest〕China's August Metals Trade Inverts as Ore Imports Fall 5-15% on Guinea Pullback, Yet Refined Zinc Exports Leap 12,980% and Alumina +135.78% — Indonesia AD Probe and CATL Restart Set the Tone

0. Weekly Arc

Friday's overnight LME session split base metals: LME zinc +1.52%, LME copper +0.68%, LME tin +0.87%, while LME nickel -0.18% and SHFE nickel -0.36% ^[1]. The US Fed rate hike landing is the headline mechanism, with AL Circle arguing accelerated aluminum ingot destocking will support aluminum prices ^[2]. Goldman's commodities desk held its year-end 2027 gold forecast at $5,400/oz despite the hike, citing central-bank diversification as the structural driver ^[1]. Yet China's August customs print tells the opposite story at the raw-material level, with broad-based ore import declines and a refined-export surge. Net: a rate-hike-anchored LME bid against a domestic supply-chain rerouting.

1. China August Trade — Ore Down

• **[NEW] Aluminum ore imports:** 15,450,843.97 tons, -18.87% m/m and -15.00% y/y; Guinea 11,551,064.40 tons (-22.37% m/m, -5.58% y/y); Australia 3,372,597.58 tons (-14.68% m/m, -23.79% y/y); Guyana 198,562.12 tons (-15.07% y/y) ^[3]. The pullback is broad-based.
• **[NEW] Zinc ore imports:** 424,981.54 tons, -0.15% m/m and -8.95% y/y; Australia 77,291.22 tons (-17.97% m/m, -4.16% y/y); Peru 75,886.93 tons (+77.48% m/m, -28.72% y/y) ^[4].
• **[NEW] Nickel ore imports:** 5,964,815.38 tons, +0.54% m/m but -5.46% y/y; Philippines 5,525,667.27 tons (+2.60% m/m, -6.33% y/y); New Caledonia 215,204.40 tons (-27.05% m/m, +27.03% y/y) ^[5].
• **[NEW] Aluminum scrap imports:** 141,782.26 tons, +18.60% m/m but -17.67% y/y; Thailand 34,124.96 tons (+32.84% m/m, -21.47% y/y) ^[6].
• **[NEW] Primary aluminum:** 185,514.79 tons, +0.16% m/m but -14.05% y/y; Russia 178,150.42 tons (+0.85% m/m, +28.99% y/y); exports 21,859.32 tons (-30.69% m/m, -14.69% y/y) ^[7]. Russia is doing the heavy lifting.
• **[NEW] Unwrought nickel:** 17,272.95 tons, -18.25% m/m and -29.29% y/y; Indonesia 5,491.88 tons (+2.54% m/m, +32.00% y/y); Australia 3,363.33 tons (+139.07% m/m, +66,992.12% y/y) ^[8]. The Australian y/y base is tiny.

2. The Refined-Export Surge

• **[NEW] Refined zinc exports:** 40,668.18 tons, +340.36% m/m and +12,980.41% y/y; Singapore 15,486.04 tons (+7,608.26% m/m) ^[9]. The y/y is a ~130x against a low base.
• **[NEW] Alumina exports:** 425,003.35 tons, +39.42% m/m and +135.78% y/y; Russia 227,770.67 tons (+27.46% m/m, +48.85% y/y); Oman 116,988.19 tons (+9.00% m/m, +50,544.24% y/y) ^[10]. Russia and Oman together absorbed 81% of the print.
• **[NEW] Alumina imports:** 349,530.97 tons, -4.65% m/m but +270.43% y/y; Australia 202,498.94 tons (-33.00% m/m, +542.85% y/y); Indonesia 142,068.69 tons (+135.88% m/m, +353.63% y/y) ^[10]. Australia m/m already turning.
• **[NEW] Refined lead imports:** 9,178.51 tons, -0.39% m/m and +404.16% y/y; Australia 6,302.70 tons (+290.74% m/m) ^[11].
• **[NEW] Aluminum alloy imports:** 71,539.47 tons, +19.50% m/m and +0.16% y/y; Russia 17,956.99 tons (+11.59% m/m, +20.44% y/y); exports 51,605.23 tons (-11.88% m/m, +77.56% y/y) ^[12].
• **[NEW] Nickel pig iron:** 961,370.33 tons, +49.90% m/m and +10.45% y/y; Indonesia 932,207.75 tons (+51.84% m/m, +10.08% y/y) ^[13]. The Indonesia-to-China nickel-pig-iron pipeline is the standout.

3. Trade and Policy Catalysts

• **[ESCALATED] Indonesia anti-dumping probe on Chinese galvanized steel:** Indonesia's Anti-Dumping Committee issued notice AD.02/591/KADI/09/2026 on Sept 15, acting on applications from PT. Tata Metal Lestari and PT. Arcelormittal Nippon Steel Indonesia, per the China Trade Remedy Information Net ^[14]. The action lands while Indonesia-origin nickel pig iron into China is simultaneously +10.08% y/y, sharpening the resource-nationalism frame ^[14][13].
• **[NEW] Zhongjin Lingnan:** Fankou lead-zinc mine resumed production on Sept 17; the company's directly controlled proven copper-lead-zinc resource base exceeds 10 million tons ^[15]. Caveat: this is a resource inventory figure, not an annual production rate.
• **[NEW] CATL Jianxiawo lithium mine:** environmental assessment approval restarted Sept 18 by Yichun Times New Energy Mining Co. for the Jianxiawo lithium mining project spanning Jiangxi's Yifeng and Fengxin counties, after a prior filing was withdrawn over website compliance issues ^[16]. The deposit is described as one of the largest single-body lithium mica operations globally.
• **[NEW] Guangzhou Futures Exchange (GFEX) lithium carbonate contracts:** minimum opening order size for LC2610 through LC2709 contracts raised to 2 lots from Sept 22, with transaction fees reset to 0.0008% of notional and day-trade close-out fees also at 0.0008% ^[17]. Quiet market-structure tightening.

4. Demand Side and Strategy

• **[ONGOING] Supply-chain security theme:** a Securities Research Index strategy report frames the global shift from efficiency-priority to security-priority supply chains, citing carbon tariffs, US/EU export controls, and resource nationalism in Indonesia, Chile, and Zimbabwe, with China's "15th Five-Year Plan" elevating energy and mineral security to a national security priority ^[18]. Thematic, not market-tied.
• **[NEW] Electrical materials demand (SMM 2026):** at the SMM Electrical Materials Industry Annual Conference "supply-demand wall", Jiangsu Yongding Shengda is buying copper conductors, Jiangyang Cable is buying copper-aluminum and plastics, Guangzhou Lingnan Cable is buying copper rod, and Suzhou Yubang New Materials is buying copper wire ^[19]. The pattern confirms copper-aluminum conductors remain the structural base of the chain. Single-conference observation.
• **[NEW] Africa lead-zinc window:** the FMIST conference flagged 5 million tons of lead-zinc resources as a Chinese "going-abroad" opportunity ^[20]. Single source.
• **[NEW] ESG as lithium "passport":** Ma Zengguang of the International Lithium Association is confirmed to attend an SMM event, framing ESG screening as a new supply-chain requirement for Chinese lithium exports ^[21].

5. What Would Falsify It

• The August customs print is a single release; the GFEX lithium carbonate fee reset on Sept 22 will be the first read on whether the market-structure tightening is a flow-control signal or a routine adjustment ^[17].
• Falsifiable test: if Indonesia's anti-dumping probe on galvanized steel expands to zinc-coated or nickel products, the resource-nationalism frame dominates the rate-led destocking thesis ^[14].
• Source quality: the Goldman $5,400/oz 2027 call, the AL Circle destocking thesis, the SMM electrical-materials supply wall, and the FMIST Africa window are each single sources ^{[2][1][20][19]}; the customs data are systematic but m/m volatility is extreme (e.g., Malaysia aluminum ore +212,924,965.00% m/m on a near-zero base in ^[3]), so quote the y/y anchor, not the m/m noise.
• Zhongjin Lingnan's 10M-ton figure is a resource inventory, not an annual production rate — production impact cannot be inferred from the material ^[15].
