Weight is the line nobody audits
Species sets density, and density sets freight weight. A hardwood 48×40 can weigh twenty pounds more than a Douglas fir unit of the same dimensions. Across six hundred pallets a month that is six tonnes of wood you are paying to move that carries nothing.
On weight-constrained lanes this is the single largest hidden cost in a pallet decision, and it never appears on a unit-price comparison. If your lane is weight-limited, specify fir or hemlock and tell your supplier why.
