The invasion of Ukraine has dealt another blow to already-stretched global supply chains, with retailer Bunnings ordering suppliers to stop buying “conflict timber” from Russia in the wake of declarations earlier this month by global forestry bodies about timber from that country and ally Belarus.

Wesfarmers-owned Bunnings said Russia was not a major source of timber for the Australian home improvements market, but warned of a shortage to supply – on top of existing constraints – of composite laminated veneer lumber, or engineered wood products, in coming months.
