Rules Change Process
Every four years, NHLA reviews the hardwood lumber grading rules and accepts rules change proposals for consideration.
In the final step of the process, ballots containing new rules change proposals are sent to all Active Members. Each Active Member may vote for or against the proposed rules change provided such ballot is returned to and received by NHLA within 30 days from the date on the ballot. Rules change proposals that receive a favorable vote on a two-thirds majority of the votes properly cast by the Active Members will be adopted and become effective January 1 of the proceeding year.
