China’s Log Demand Drops as Record Heatwave Stalls Construction

China’s record-breaking heatwave, which has so far caused a power crisis and a major slowdown in construction activity, is to blame for a decline in log demand at ports (down from 60,000 cubic metres in June to 50,000 in July). That is according to Scott Downs, New Zealand-based PF Olsen’s Director Sales and Marketing, who reports that a drop in demand from China (due to heat) and India (thanks to monsoonal weather), resulting in the the export market for radiata pine remaining largely in step, due to in large part to reduced harvest volumes (caused by poor weather across NZ).  

After 27 years, India has removed the ban on the use of timber in construction of buildings. The decision oy the Central Public Works Department, the prime construction agency of the central government, comes after the Union Environment Ministry asked the department to remove the ban, saying it would build jobs and create demand for eco-friendly and sustainable building practices.

“In the domestic market, New Zealand sawmills continue to face pressure from rising operational costs,” Downs said. “Carter Holt Harvey (CHH) has announced an upcoming price increase for structural sawn timber, effective from October,” whilst Moody’s revised global outlook for the forest products sector has been changed from stable to negative, citing the combined impact of rising tariffs and weakening demand: “This shift presents challenges for NZ’s export-reliant forestry sector, particularly in the pulp, panel, and sawn timber markets,” he said.

“Tariff increases in key markets have disrupted trade flows and added cost and complexity across the supply chain. New Zealand exporters are facing tighter margins as raw material and freight costs climb, while buyers reassess sourcing strategies amid geopolitical and economic uncertainty.”

According to Downs, softwood log imports from Europe dropped 59% for the first half of 2025, down more than 1.14 million cubic metres over the same period in 2024: “Strong prices persist, but buyers face margin pressure from weak demand and high raw material costs,” Downs said. Whilst at Wharf Gate (AWG), prices for New Zealand export logs rose only 1 NZD per JASm3 in July, as currency shifts offset higher CFR prices.
