China publishes mid-March commodity prices: chemicals and fuels surge double digits, metals and coal weaken

China's official price tracker shows that between early and mid-March 2026, prices for chemicals (methanol up 9.8%), plastics (polyethylene up 10%), and fuels (gasoline up 11.4%, diesel up 10.1%) jumped sharply, while metals like copper and zinc declined. This is a routine monthly snapshot of wholesale prices at distribution points across nine commodity categories—useful for tracking whether manufacturing costs are rising or falling in the world's largest goods producer.

Price moves in Chinese commodity distribution tell you what manufacturers actually paid for inputs in the weeks ahead of production. When chemicals and petrochemicals spike this hard in a single half-month, it ripples: factories building plastics, textiles, pharmaceuticals, and fertilizers all face higher input costs immediately. The weakness in metals (copper down 1.9%, zinc down 2.5%) while fuels and chemicals surge suggests energy and feedstock pressures are outpacing demand for metal-intensive construction and machinery—a divergence worth watching. For anyone tracking Chinese factory health or global input cost inflation, this data is primary evidence, not commentary.
