Kiln Drying Certification

Has the ever increasing costs of shipping export hardwood lumber got you down? Completely fed up with scheduling a shipment around someone that does not work for you? Would you like to save time and money? Then the APHIS-Approved NHLA Certification of Kiln Drying Sawn Hardwood Lumber Program is for you!

The Program which was initiated by APHIS is controlled through a Memorandum of Understanding between the two organizations. The Program achieves the same goals as the APHIS Phytosanitary Certificate but at less cost both to APHIS and the U.S. hardwood industry. The system mirrors the successful fifteen year old softwood certification program previously developed by APHIS for the European Union.

The USDA-APHIS is actively pursuing the acceptance of the program in many countries including China. Below is a current list of countries that are accepting the NHLA Kiln Drying Certificate:
