• China's state-owned iron ore buyer, CMRG, will restrict delivery of certain Fortescue products from July 15, according to sources.
  • The move signals continued strategic leverage by CMRG as negotiations with major miners evolve.
  • Steelmakers face potential supply constraints, affecting port stockpiles and pricing dynamics.

China Mineral Resources Group (CMRG) is tightening access to some portside iron ore products from Fortescue, with restrictions taking effect July 15, according to people familiar with the matter. The state buyer has informed certain steelmakers that they will be unable to take delivery of specific Fortescue grades, though the companies may still purchase the ore via other channels.

The restrictions come amid ongoing negotiations between CMRG and major miners over contract terms, including pricing mechanisms and settlement currencies. CMRG, established in 2022 to consolidate China's iron ore purchasing power, has been using centralized buying to push for more favorable terms and greater use of yuan-denominated transactions.

"It's part of a broader strategy to shift pricing leverage," said a source close to the negotiations, speaking on condition of anonymity. "CMRG is signaling that access to seaborne ore is conditional."

The move follows a period where CMRG had restricted purchases of some BHP (BHP) products before partially easing them earlier this year. Analysts note that the restrictions could tighten spot supply and support prices, but may also accelerate efforts by miners to diversify their customer base.

"We've seen this playbook before," said a Beijing-based steel analyst. "CMRG uses restrictions as a bargaining chip, then gradually relaxes them as deals are struck."

Steelmakers have been bracing for potential disruptions. One mill procurement manager said the company has been diversifying suppliers and building portside inventories. "We can't rely on just one source," he said.

CMRG did not respond to requests for comment. Fortescue declined to comment on commercial matters.
