Wood dunnage is one of the easiest types to obtain because its often available in abundance on warehouse or facility floors and it can be fit to just about any size shipment. Besides flexibility and availability, wood is super-efficient and environmentally friendly. In fact, wood is the only 100% renewable resource in the manufacturing of building products.

With all of these benefits though, wood dunnage does come with caveats. Mainly, certain federal regulations must be adhered to in order to avoid fines, export delays, penalties, or damage to the environment.

If you follow the rules, you will enjoy all of the benefits this popular material has to offer, while staying in compliance with government rules. This post will guide you through the regulation hoops to help you decide if this material is a good fit for your company’s packaging needs.

ISPM 15 Heat Treatment: Don’t Do Wood Dunnage Without It

If your company ships its products overseas, then you need to know about ISPM 15—the heat treatment of wood. If you don’t learn about it before your next big shipment, you face certain consequences for non-compliant wood products.

Heat treatment (HT) is a non-chemical process to kill pests in wood to assure the health of other ecosystems. This thermal treatment goes beyond the surface to kill any living organisms and improve resistance to rot and fungus.

The Heat Treatment Program was developed in order for the American Lumber Standard Committee (ALSC) to implement a quality control program for the official labeling of heat-treated wood packaging material (WPM) with an ISPM 15 Stamp. The measure applies to many wood packaging materials but excludes products made from alternative materials such as OSB, hardboard, and plywood.

Dunnage is often used in conjunction with wood shipping crates to restrict the movement of the internal products or to keep the crate static during transit. Generally, this packaging material is just reused pieces of lumber, however if a customs official inspects the inside of the crate, each piece must bear the ISMP 15 heat treatment stamp.

Valley Box Company

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 external 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.
