The Southern Pine Inspection Bureau (SPIB) issued Supplement No. 10 on October 26, 2011.  According to the release by SPIB, “ Supplement No. 10 makes no changes to the 2002 Edition of the Standard Grading Rules for Southern Pine Lumber except for the following:

Supplement No. 10 adds additional grades of MSR and MEL. The American Lumber Standard Committee has been notified of the addition of these grades.”

It is important to note, this does NOT change any of the visual grade Southern Pine design values.

In essence, Supplement No. 10 adds 17 additional MSR grades (as low as 750), and 11 MEL grades (M-32 through M-42). We are not aware of any MSR and MEL using these new machine stress rated lumber grades currently being produced.  Therefore, this change does not have an immediate impact, but rather serves as a foundation for possible future machine stress rated lumber use.

Please contact us immediately if you become aware any of these additional grades of MSR or MEL are being produced.
