China's Base Metal Trade Shifts: Six Charts Show Copper Falling, Aluminium Surging

By Crypto Desk July 28, 2026

China's outsized role in global base metal markets is showing sharp divergence this year — copper imports are sliding while aluminium exports surge, and several metals have posted surprising trade twists through the first half of 2026.

Key Fact: China's net copper imports fell 13% year-on-year to 1.374 million metric tons in H1 2026 — the weakest first-half reading since 2017.

Copper: China Faces New Competition for Metal

China's net refined copper imports dropped to 1.374 million metric tons in the first half of the year, according to the World Bureau of Metal Statistics. Imports fell 10%, while exports — including metal drawn from bonded warehouse stocks — rose 5% to 324,000 tons. High prices curbed China's import appetite early in the year, but the country is now also competing directly with the United States for available copper, as threatened US import tariffs have pushed the CME price above international benchmarks. That competition looks set to intensify: Shanghai Futures Exchange copper stocks have fallen to a two-and-a-half-year low of 69,610 tons, while a spike in the closely watched Yangshan premium signals rising spot demand.

Aluminium: Exports Surge to Fill a Gulf Supply Gap

The aluminium market is betting that rising exports from China and Indonesia can offset lost production in the Gulf region caused by the Iran war. China's primary aluminium exports remain constrained by a steep 30% export tariff, so its supply response has instead come through semi-manufactured products like plate, sheet, and foil. These product exports fell 9% between 2024 and 2025 after Beijing removed a 13% tax rebate, but rebounded 15% in the first half of 2026. Notably, outbound volumes have risen every single month since the Iran war began in February — a clear sign of China stepping into the supply gap.

Key Stat: China's refined zinc imports collapsed 79% year-on-year to just 38,000 tons in H1 2026, the lowest since 2022.

Zinc: China Edges Toward Self-Sufficiency

China's net refined zinc imports plunged 79% year-on-year to just 38,000 tons in the first half of the year — the lowest reading since 2022, when Western smelter outages briefly turned China into a net exporter. Years of added domestic smelting capacity now have China showing clear signs of reaching self-sufficiency at the refined zinc stage, and the country could turn net exporter again given renewed tightness in the London Metal Exchange zinc contract.

Lead and Nickel: Two Unexpected Import Surges

Lead told a very different story. China's refined lead imports jumped to 147,000 tons in H1 2026, up from just 17,000 tons a year earlier — the highest annual tally since 2009. Since lead concentrate imports also rose 5%, the surge doesn't reflect a feed shortage at primary smelters; instead, a scrap shortage appears to have squeezed China's secondary lead production, driving up import demand.

Nickel imports surprised similarly. China's refined nickel imports reached 149,000 tons in H1 2026, up 58% year-on-year, with net imports of 138,000 tons already exceeding any full year since 2021. Indonesia was the single largest supplier, accounting for almost a third of total imports.

Tin: Myanmar's Return Stabilizes Supply

China remained a marginal net importer of refined tin, at roughly 1,500 tons in H1 2026, continuing a pattern of broadly balanced trade. The bigger story is the recovery of raw material flows from Myanmar: a prolonged closure of the Man Maw mine had caused tin concentrate imports from Myanmar to collapse from 181,000 tons in 2023 to just 35,000 tons in 2025. With the mine now back online, albeit at reduced rates, imports from Myanmar tripled year-on-year to 39,500 tons. Combined with a doubling of imports from Bolivia and steady supply from the Democratic Republic of Congo, overall tin concentrate imports have stabilized after two years of contraction.

Why It Matters

China's dual role as the world's largest metal consumer and producer means its trade patterns often ripple through global commodity markets well beyond its own borders. This year's divergence — falling copper and zinc imports alongside surging aluminium exports and record lead and nickel inflows — reflects how differently each metal market is responding to tariffs, geopolitical disruption, and shifting domestic production capacity. With US-China copper competition intensifying and aluminium exports still climbing amid the Gulf supply gap, these trends are likely to remain a key factor shaping global metal prices through the rest of 2026.

Japan Earthquake Impact on Tech Stocks Seen as Limited

July 28, 2026

Japan's Nikkei Stock Average fell sharply Wednesday following Tuesday's earthquake in the southern prefecture of Kumamoto , but analysts say the disaster shouldn't pose a lasting threat to tech share prices if damaged semiconductor factories can resume operations within roughly a month. Key Fact: The Nikkei Stock Average fell 2.2% following the Kumamoto earthquake, as investors weighed potential disruption to Japan's semiconductor hub. A Familiar Playbook From 2016 Daiwa Securities analyst Eiji Kinouchi pointed to the 2016 Kumamoto earthquake as a useful reference point for how markets might respond this time. During that event, production halts at affected factories were mostly resolved within a month, and tech stocks experienced only a single-day dip before recovering. Kinouchi suggested a similar pattern could play out now, with the key variable being how quickly damaged facilities can restart output. Kumamoto sits at the heart of Japan's semiconductor ...
