Heat-treated Lumber
If you build or repair wooden
boxes,
crates,
pallets,
skids,
dunnage or other wood packaging
for shipping, you must use heat-
treated (HT) lumber. Heating kills
any
roundworms
lurking
in
the
wood. Authorities at domestic and
foreign ports and air terminals can
refuse to forward shipments if the
WPM is not heat-treated and lacks
certiFcation markings.
A lumber mill must heat the wood at a
minimum temperature of 133°± for 30 minutes
straight. The mill will then stamp the lumber
with HT. That mark tells you the lumber is
approved for building WPM. If you purchase
lumber locally, make sure it’s marked HT. If it
isn’t, don’t use it.
You can also order lumber and wood products
from the Defense Logistics Agency (DLA). Go
to the Wood Products page on the DLA Troop
Support Construction and Equipment website:
CE/WoodProducts/
Once you reach the web page, click
on Wood Products Prime Vendor. At
the bottom of the next page are phone
numbers for the wood product program
manager. Below the phone numbers is

Catalog. Click on it. You’ll be taken to
a catalog for lumber and wood products.
The catalog includes a list of MIL-Specs,
NSNs, types of wood and suggestions
for typical use. When the DLA wood
arrives, look for the HT mark.
Certification Mark
In
April
2009,
revisions
to
international
regulations changed the format of the certiFcation
mark. “DoD” (or “DoD DUN” for dunnage
stamps) has moved outside the border of the
mark. This doesn’t mean you have to get rid of
your old-style stamps right away. There will be
a changeover period while new stamps become
available. Until you receive your new stamps, use
your current ones as long as they’re legible.
You can stamp, stencil or brand the certiFcation mark onto the wood. If you wear
out lots of stamps because you build lots of WPM, order a branding iron from the
USAMC LOGSA PSCC .
Once you’re WPM certiFed, contact LOGSA PSCC for information on stamps,
stencils and branding irons. You’ll Fnd phone numbers and an email address at the
end of this article.
Secure WPM stamps, stencils and
brands before you leave your work
area. You don’t want to lose them.
When you build WPM, record your
daily lumber usage. Ask your shop
leader or WPM site custodian for a
marking log or a cut and fabrication
work order form. A record of lumber
usage is required by DoD 4140.65-M
and the American Lumber Standard
Committee,
Incorporated®,
Wood
Packaging
Material
Enforcement
Regulations (Nov 09 w/Ch Jul 10).
Certification
If you work with WPM, you’re required to take
WPM Certifcation Training.
You must
retake
the training every two years. That way inspectors, packers, wood
fabricators and assemblers stay current with policy and procedure changes.
±or more information about WPM CertiFcation Training, contact the USAMC
Loogistics Support Activity (LOGSA) Packaging, Storage and Containerization
Center (PSCC). You’ll Fnd PSCC phone numbers and an email address at the
bottom of this page.

What is Dunnage?
Dunnage is material used to secure or support the cargo
being shipped. Examples of WPM used as dunnage are bracers,
sleepers, spacers, cross members, headers/footers, and kickers.
