The mills listed here are the buyers at the end of the line for Washington wood. A landowner rarely sells straight to one: a mill buys wood delivered to its gate, and getting trees there takes a logging crew, so the offer in front of you normally comes from a logger, a timber dealer, or a consulting forester selling on your behalf. Which mills sit within reach of your county is what decides who those bidders are and what they can afford to pay.
Haul distance is why a state mill list is worth anything to a seller. Trucking comes out of the same load the timber does, so a tract twenty minutes from a mill is worth more than the identical tract two hours away - same trees, different cheque. This page carries 81 facilities across 25 counties, all of them on the map above, so you can see what sits within working distance of your ground before anyone quotes you a number.
45 of the 81 Washington listings are sawmills, alongside 10 pulp & paper mills, 10 remans, 6 engineered woods, and a few other plant types. Tops and small stems are sold as pulpwood, and the 10 pulp & paper mills and 1 chip mill on this page are where that wood is taken. The Washington records name what each plant accepts - fir, hemlock, cedar, pine, and spruce among 13 species in all - so the species line on a card tells you whether your stand is what that mill runs. A stand is usually worth sorting into products - pulpwood, chip-n-saw, sawtimber, and veneer where the logs justify it - rather than selling the lot as one thing, and the mill type and species lines on every card below are where working that out starts.
Whoever ends up cutting it, run a process instead of taking the first offer. Hire a consulting forester who works for you, have the timber cruised and marked so every buyer is bidding on the same defined lot, then take sealed bids opened on a stated date. One unsolicited offer is a price, not the price. The landowner's guide walks the whole sale in the order it happens, and sealed bidding is how you put one tract in front of several buyers at once.
12 species are named across these Washington listings, fir by 38 of them. There is a guide here for Southern yellow pine and black walnut, each one covering grade, form, the defects that cost money and what the wood is normally cut for - which is how you work out whether your stand is what these mills run. Shorter entries on the same page cover Douglas-fir and spruce and true fir - what buyers take each for, and the catch.
Washington Department of Natural Resources publishes results of every state timber auction, sale by sale. Updated monthly. That is public record rather than a licensed average, so the page on timber prices in Washington can carry the figures themselves, each one with the sale and the edition behind it. A state average is still not your cheque - species, county, and which mills are buying this quarter decide that, which is the argument the market board makes at length.
Nothing bordering Washington is in this dataset yet - the agencies next door publish no list that could be fetched. Montana's 99 listings, Colorado's 58 listings and New Mexico's 50 listings sit in the same part of the country and are the nearest coverage here; the state-by-state index has the rest.
