China die-cast zinc alloy exports rise in August

The rebound in exports came after July’s pullback and was concentrated in Asia. Vietnam remained the biggest destination at 1,293.1 tonnes, or 58.33% of the total, while Taiwan, China emerged as the largest new destination, taking 675.7 tonnes. Exports to Thailand, Singapore and Cambodia also increased, while Bangladesh fell sharply. The diversification suggests Chinese suppliers are finding demand across more regional buyers, even as Southeast Asia remains the key anchor.

That export recovery is being driven by economics rather than pure volume appetite. The Shanghai/LME zinc price ratio remains relatively low, giving Chinese material a relative cost advantage abroad, while domestic supply is ample. Traders and producers appear to be leaning into that spread at a time when terminal hardware makers are expanding overseas, reinforcing the role of Southeast Asia as a manufacturing hub and a customer for Chinese semi-finished metal products.

Imports, by contrast, stayed muted rather than collapsing. South Korea, Thailand and Japan supplied 80.37% of August inflows, with gains from South Korea and Thailand offsetting declines from Australia and Japan. The stability matters because it points to a market that is not short of material, reducing the incentive to bring in overseas cargoes when domestic supply is sufficient and end-demand is still soft.

The broader backdrop is not especially supportive for either side of the market. Zinc futures have been grinding higher on firm spot demand, even as smelter economics remain under pressure from lower sulfuric acid prices and negative treatment charges. Inventories have also been rising, a sign that the market is cautious and that any supply recovery remains limited. For exporters, that tension can still support outbound flows; for importers, it keeps the upside constrained.

For investors, the August data reinforce a simple trade-off: Chinese zinc alloy producers with export exposure may be better positioned than those reliant on domestic absorption, but a sustained rally still depends on whether overseas demand, regional manufacturing activity and the zinc price spread remain favorable. If the spread narrows or downstream hardware demand softens further, the export rebound could prove temporary.
