Maine prohibits the entry of all types of out-of-state firewood unless it has been heat-treated to at least 160°F for 75 minutes and is packaged and clearly labeled with the evidence of heat treatment and the origin of the firewood.
Any firewood that does not meet the above standard may be confiscated and properly disposed of to prevent the escape of invasive forest pests that could be hiding within the wood. If transporting firewood within Maine, carry proof that the firewood originated within the state. Also keep in mind that it is illegal to move firewood out of some areas in Maine due to the infestation of harmful forest pests (e.g., emerald ash borer) that are already present in those areas; make sure your area is not under quarantine before transporting firewood.
Maine’s firewood quarantine is in place to protect the state’s natural and agricultural resources from destructive tree pests like the Asian longhorned beetle, emerald ash borer, and spotted lanternfly. Pests like these spread and infest new areas when people move firewood from location to another.
New Hampshire and Canada also prohibit the entry of untreated firewood; so any firewood leaving Maine must be certified, heat-treated. Many campgrounds in Maine have their own firewood policies (e.g., Baxter State Park prohibits all outside firewood), and they often ask campers to buy firewood where you burn it.

Bringing firewood from Canada into the USA is prohibited unless the firewood is labeled and certified heat-treated. Read about these requirements on the USDA and CBP firewood information sheet.
Bringing firewood from the USA into Canada is prohibited unless the firewood is labeled and certified heat-treated. Canada also encourages visitors to use local firewood through their campaign buylocalburnlocal.ca.
