The following text identifies the import requirements for wood packaging, including dunnage, for all species to the United States (U.S.)

Requirements for All Species

Please note that wood packaging (W.P.) used in the transport of goods to the United States (U.S.) from Canada may be inspected by U.S. Customs and Border Protection to verify that it either complies with the requirements of International Standard for Phytosanitary Measures (ISPM) 15 or is eligible under the Canada-U.S. exemption from ISPM 15.

All shipments of goods with wood packaging to be exported to the U.S. must meet the following W.P. requirements:

  1. The W.P. must be free of live pests, weed seeds and soil;


  2. The W.P. must have been produced from wood that originates from either Canada or the U.S. and the accompanying export/shipping documents must clearly state that any unmarked wood packaging in the shipment was produced in either the U.S. and/or Canada (as the case may be). Note: the obliteration of any markings on the wood may be considered as removing marks which identify the wood as having an origin other than Canada and the U.S. and may result in U.S. authorities considering the wood as non-compliant.


  3. The W.P. is identified with legible ISPM 15 marks. Re-used repaired wood packaging should be marked in accordance with the Canadian Heat treated Wood Products Certification Program (Policy D-13-01)

In the case where shipments may consist of units of wood packaging of differing origins (e.g. mixed loads), the exporter must ensure that all the wood packaging clearly meets the standards above (e.g. within the mixed shipment, the unmarked wood packaging is identified as being produced in Canada or the U.S. on shipping documentation and ISPM 15 marks appear on any re-used offshore wood packaging).
