OSFM 2520 Treated Lumber census

All 5 live OSFM Treated Lumber listings in the 2026-08-25 snapshot. Each row preserves the BML application number, issue date, and expiry date; linked product records are supporting detail, not additional listings. 2 of these listings have no product page: the Scope column says why, most often because the manufacturer's own use limits put the product outside this site's exterior-WUI scope.
