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 one of 2 facilities listed in Mecklenburg County, which is where a search for a sawmill near me starts if your ground is in that county. The Mecklenburg County section of the state page has every one of them side by side, and all 245 North Carolina listings run across 81 counties - which is the map that decides whether a load leaves your gate for twenty minutes or two hours.
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 Fisher's Lawn Service in Terrell, 13 miles away, Timber Creek Mulch, LLC in Sherrills Ford, 15 miles away and Mr. Tommy's Firewood in Woodleaf, 31 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.
