Low-grade hardwood (oak, poplar, mixed) is the traditional raw material for eastern stringer pallets, much of it cants and pallet stock from grade sawmills.
WPU0812 was 285.075 in September 2026 (preliminary), −0.5% on the month, +1.3% on the year and −3.7% over five years.
Over the last 120 months, the twelve-month change in WPU0812 and the twelve-month change in the wood pallet PPI (WPU084101) had a correlation of 0.76 (Pearson, on year-over-year percent changes). A value near 1 means they rose and fell together; it says nothing about which caused which.
