Firewood Dealer Certification
Under a voluntary program, a firewood dealer can be certified so their wood, grown and cut in Wisconsin, can be used in State Parks and state-managed lands throughout Wisconsin.
This certification is not required to sell firewood in Wisconsin.
There are two steps to becoming certified:
- Complete and submit a certification application
- Inspection by DATCP to verify the information presented on the application form.
The certification is valid for one year.

- The firewood is stored on the dealer’s premises for at least two years before it is sold or distributed in Wisconsin.
- The firewood is treated in a manner approved, in writing, by the Wisconsin Department of Agriculture, Trade and Consumer Protection, to kill all pests that may inhabit the firewood.
