Per the ISPM 15 standards all wood dunnage (blocking) must be heat treated as well. We apply our dunnage stamp to all blocking done on our heat treated crates.

Customers frequently ask what the ISPM 15 standards are for wood packaging materials and when heat treating is required for shipping crates. The text below is quoted from the USDA website and elaborates on the standards and the classifications of wood packaging material.


Wood packaging material or WPM is also called Non-Manufactured Wood Packing (NMWP) or Solid Wood Packing Material (SWPM) defined as "hardwood and softwood packaging other than that comprised wholly of wood-based products such as plywood, particle board, oriented strand board, veneer, wood wool, etc., which has been created using glue, heat, and pressure or a combination thereof used in supporting, protecting or carrying a commodity (includes dunnage)."

Examples of WPM includes but not limited to pallets, skids, pallet collars, containers, cratings/crates, boxes, cases, bins, reels, drums, load boards, dunnage. Wood packaging made of exempt materials but combined with solid wood components must still be treated and marked.

Our customers frequently ship out of the port of Long Beach and the port of Los Angeles. If you are in need of a heat treated export crate or any in air freight going out of LAX and Orange County (John Wayne International Airport), please give us a call and we will be happy to discuss ISPM 15 regulations with you.
