The source goes no further than hardwood and softwood here, which is a starting point rather than a specification. The species guides take the trees one at a time - what each is cut for, how it is graded, and where the line between pulpwood and sawtimber falls.
It is the only facility the Texas sources list in Morris County, which is worth knowing before you plan a haul: the next gate is in another county. The Morris County section of the state page shows it standing alone, and all 106 Texas listings cover 44 counties.
Anybody searching for a sawmill near me needs more than one gate. If this one will not take your wood, the nearest other listings are Pleasant Pallet in Cookville, 10 miles away, Johnny Stacks Mill, LLC in Naples, 14 miles away and Cypress Lumber Co. in Mt. pleasant, 17 miles away. Distances are straight lines between the coordinates the sources published - not road miles, and not a statement that anybody is buying.
None of this says whether the gate is open or what the load would fetch - no agency document records that. A price comes out of a sale run properly: the landowner's guide to selling timber takes the steps in the order they happen, and sealed bidding puts one tract in front of several buyers at once instead of taking the first number offered.
