International regulations :
The International Plant Protection Convention mandates that wood packaging used in international trade must be treated to guard against the distribution of unwanted pests.

Wood Packaging :
any type of packaging such as pallets, Boxes, Skids, Crates, Heavy / Light Packaging or Supporting Material (dunnage) made from Raw Wood Materials.

Excluded from wood packaging materials :
Paper products, products manufactured using heat, glue and/or pressure (plywood, particle board, etc), sawdust, wood wool, shavings and raw wood 6mm or less in thickness

Requirement for wood packaging for Export :
All wood packaging for export (except to the U.S.) must have been made from wood heat treated to a core temperature of 56°C for 30 minutes (either before or after manufacture).

What happens if I send product on wood packaging that is not ISPM 15 certified ?
The importing country has three options to accept your product if shipped on noncertified ISPM 15 wood packaging.
1. quarantine and return to shipper on the next available transport ship – cost
unknown but will include cost of dock space rental.

2. offer treatment of the non-certified wood packaging – estimated cost $5000.00
USD – includes opening container and storage

3. cross-docking of your product from non-certified to certified ISPM 15 wood packaging.
– cost unknown but considerable ISPM 15 certification prior to shipping is the cheapest option if you export.

Difference between HT and KD :
Heat treating (HT) is a pasteurizing process. Kiln dried (KD) is moisture reduction. 
Your lumber can be HT or HT-KD. Lumber that is just KD is not eligible.

Process of packaging professional certify the packaging :
Your supplier will provide their license number in the form of an approved IPPC stamp
on at least two sides of the packaging. The stamp looks like this:
XX is the country of origin (India = IN)
000 is the license number
YY is the treatment
(Heat treated = HT)
(Heat treated dunnage = D-HT)
