That said, importing plant material (including aquatic plants, wood, leaves, etc) without the proper certificates and documentation is not responsible behavior. Some of the worst diseases and pests including Dutch Elm Disease, 1000 Cankers Disease, and Japanese Beetles that threaten our beautiful native forests all 'hitchhiked' to the US on plants and wood products. That is why our US Government requires inspections and certificates. If a shipment is improperly documented, and is caught by US Customs, the goods are confiscated and fines may be issued to the individuals that imported the items. It is the buyer / importer (you and me) that are required to know the laws and insure that shipments are properly documented.
I am not trying to scare you but I would encourage you to be responsible and not to order plants or plant material like wood or leaves from overseas in the future.
Oh that's a relief, I thought the US customs must require all wood to be sprayed if there isn't any documentation provided. This is my first international purchase of wood and I did not know such laws existed, but ignorance is not an excuse in the society we live in today. Thanks for the information you provided, I found it hard and tedious to find the information on customs.
