• Manufactured wood materials such as fiber board, plywood, whisky and wine barrels, plywood, strand board, and veneer,
• Pieces of wood that are less than 6 mm (0.24 in) in any dimension,
• Sawdust, wood wool, and wood shavings, produced as a result of sawing or shaving wood into small, slender, and curved pieces less than 6 mm in any dimension, and
• WPM used by the U.S. Department of Defense (DOD) to package non-regulated articles, including commercial shipments pursuant to a DOD contract.

Firewood, mesquite wood for cooking, and small, noncommercial packages of unmanufactured wood for personal cooking or personal medicinal purposes will continue to be allowed to enter directly from Mexican border states.

In addition, by reciprocal regulations in the U.S. and Canada, WPM made entirely from Canadian origin wood or U.S. origin wood are exempt from the treatment and marking requirements in trade between the two countries. Please see additional detail in the next few questions for shipments to and from Canada.

USDA has grandfathered in all wine crates for vintage years preceding 2006. This means that wine crates for any wine with a vintage year through 2005 are exempt from treatment and marking requirements regardless of when entry is made. Wines of vintage year 2006 and beyond will be required to be in crates that have been treated and marked.

Articles of wood that are manufactured to transport a specific non-regulated commodity (for example, fuel gauges, armaments, ammo boxes, etc.) are not considered to be WPM and are not required to be treated and marked.

WPM that is part of any bundle of imported lumber is exempt from the rule. Other WPM used in the transport of bundled lumber (for example, pallets or planks) are not exempt and are regulated WPM.

There is no requirement for treatment or marking of WPM in domestic circulation.

For purposes of enforcement of the USDA WPM rule, CBP has decided that the country of origin of the commodity is the country of origin of the WPM on all shipments coming from Canada absent an indication to the contrary. In other words, WPM in shipments of Chinese-made goods coming from Canada will be considered Chinese and must be treated and marked unless there is documentation to prove the WPM is Canadian. WPM in shipments of Canadian-made goods coming from Canada will be considered Canadian and need not be marked.

• If the country of origin of the goods is Canada, and the goods are coming directly from Canada into the U.S., we will hold that the country of origin of the WPM is also Canada absent an indication to the contrary. Canada origin WPM is exempt from the regulation, so nothing more is required.
• If the country of origin of the goods is, say, China, and the goods are coming directly from Canada into the US, we will hold that the country of origin of the WPM is also China absent an indication to the contrary; China origin WPM need to be treated and marked.
• If the country of origin of the merchandise, to follow through on this example, is China, but it has been repackaged in Canada on Canadian WPM, and the shipment is coming directly from Canada into the U.S., we will still hold that the country of origin of the WPM is China absent an indication to the contrary. A statement is the simplest way to provide CBP with an indication to the contrary.
  In a nutshell, then, if other-than-Canada origin merchandise is coming directly from Canada into the U.S. with Canada origin WPM, CBP needs some way to know that the WPM are Canada origin. This can most simply be a statement that the officer will see when the load arrives.
