Updates to the WPM Enforcement Regulations

​In November 2025, the American Lumber Standard Committee had a full committee meeting and voted on some changes to the WPM Enforcement Regulations. Lee Global wants to keep you up to date on those changes, so we break them down for you here. As always, if you have questions, please don’t hesitate to ask your auditor, or call our office for more information!

1. The removal of Section 4.1.1.1.1, which stated:

For material to be considered as HT when received by a facility under section 6.2.3 of the Lumber Enforcement Regulations, the material shall meet all conditions of 6.2.3 of the Lumber Enforcement Regulations, and in addition the following requirements must be met for this material to be considered as heat treated:

• The material must be rough.
• No further processing of the material shall occur.
• The shipment must be direct and must remain intact from the producing mill to the purchasing user.
• Invoices or other appropriate records indicating size, volume, and number of units must verify traceability from the producing mill to the end user.
• All units shipped shall be marked with a legible stencil that indicate the ALSC accredited agency trademark, the words “WPM USE”, and the mill number or name. The stencil shall be applied to the lower corner of each unit.
• This stencil shall not be applied to any bundles that are not being properly monitored through acceptable 6.2.3 procedures. Wood Packaging Material Enforcement Regulations American Lumber Standard Committee, Incorporated® November 1, 2024
• Once received by the purchaser, the material cannot be transferred to another facility for use as HT material. If the material is transferred, the stencil shall be removed. If the material is being transferred to be used as HT the stencil shall be removed, and an HT stamp must be applied by the original purchaser to the individual pieces of material.
• When multiple accredited agencies audit the different mill, facility, or kiln operation, each auditing agency shall be permitted access to review the quality control records of both treating and processing operation to verify compliance.
• Only the agency of the supplying mill and the agency of the receiving facility are allowed to complete the 4.1.1.1.1 agreement. (4.1.1.1.1 added Nov. 4, 2022,modified Nov 1, 2024)

1. An editorial change to Section 4.1.1.2, which now states:

The volumes of HT or KD HT wood being purchased from agency certified HT or KD HT facilities are adequate based upon documentation to produce the quantities of wood packaging pallets, crating, boxes, dunnage, etc. that are being labeled. An accredited agency shall have an ongoing practice of confirming quantities of wood purchased and volumes of WPM produced, generally monthly.
This change will affect the internal company policies of Lee Global, Inc. Clients will now have one business day from the date of their routine audit to provide Lee Global, Inc. with activity figures if they cannot be provided at the time of audit. If activity figures are not provided within 24 hours, the audit will be considered non-compliant. As always, customers should strive to have monthly activity records completed by the 1st business day of each month to prevent non-compliance issues from occurring. We sincerely thank you for your cooperation in this matter!
​
Additionally, the ALSC committee made an editorial change to the ALSC Ratified Responses as it pertains to confusing or deceptive mill stamps. Previously, the practice was that products were permitted to be stamped with marketing and other language, provided that such other information was at least six inches from the grade-stamp and such other information was not confusingly or deceptively similar to the grademarks of an ALSC accredited agencies. Now, this six-inch rule has been removed. It is requested that information still not be confusingly or deceptively similar to the grademarks of an ALSC accredited agency, but information is permitted to be labeled within six inches of the grademark.
