How to Buy Dunnage with ISPM 15 Heat Treatment

If your company ships its products overseas then you probably know all about ISPM 15, the heat treatment of wood, and that exporters face consequences for non-compliant wood products.  If you're asking yourself "Why do I need to heat treat wood?" you need to read this other Valley Box article.

In a nutshell, Heat treatment (HT) is a non-chemical process to kill pests in wood to assure the health of other ecosystems. It's a thermal treatment that goes beyond the surface to kill any living organisms along with improve resistance to rot and fungus. The Heat Treatment Program was developed in order for the American Lumber Standard Committee to implement a quality control program for the official labeling of heat treated wood material with an ISPM 15 mark. The measure applies to many wood packaging materials but excludes products made from alternative materials such as OSB, hardboard, and plywood.

Companies who export their products overseas sometimes require loose lumber, otherwise known as dunnage. It's used in conjunction with the wood shipping crate to restrict the movement of the internal products or to keep the crate static during transit. Generally dunnage is just reused pieces of lumber, however if a customs official inspects the inside of the crate, each piece of dunnage must bear the ISMP 15 heat treatment stamp.

Unfortunately, packaging manufacturers are not legally allowed to sell loose lumber featuring their permitted "ISPM 15 HT" stamp. However, Valley Box can sell lumber stamped “ISPM15 HT DUN” indicating dunnage that's been heat treated. There are a few key things to keep in mind:

  • HT Dunnage can only be used for internal blocking and bracing, not exterior additions to the wood crate.
  • HT Dunnage ISMP 15 identification numbers must match any other wood used in the construction of the wood crate.
  • ISMP 15 identification numbers can be mixed only when dunnage is used to block and brace the wood crate inside a shipping container and is not a part of the construction.
