That brings up an interesting rabbit hole. Here's the CME contract specs for lumber futures:
>Each delivery unit shall consist of nominal 2x4's of random lengths from 8 feet to 20 feet. Each delivery unit shall consist of and be grade stamped #1 or #2 and Better. Each delivery unit shall contain lumber produced from and grade stamped Hem Fir (HF), Douglas Fir (DF), Fir Larch (FL), or Spruce Pine Fir (SPF).

They then go into autistic detail in section 6304 on page 4: https://www.cmegroup.com/content/dam/cmegroup/rulebook/CME/II/50/63.pdf

And for quality:
>The lumber shall meet the requirements of PS 20 or CSA O141 and shall comply with the requirements for inspection and reinspection of an agency accredited by the American Lumber Standards committee and/or Canadian Lumber Standards Accreditation Board.
