Do I need to submit supply chain documentation with my declaration?

The 2008 Lacey Act amendments do not impose any additional paperwork or reporting requirements beyond the import declaration. However, those responsible for transporting, purchasing, and processing regulated plant products entering the United States should know their supply chain. The Lacey Act requires, in an exercise of due care, that you know the plants or plant products were not taken, possessed, transported, or sold in violation of the Act or in a manner unlawful under any underlying law, treaty, or regulation. Those who either knowingly or unknowingly accept illegally taken and transported plant products, including timber, may be subject to penalties for violating the 2008 Lacey Act amendment.
