• Obtain a phytosanitary certificate from the exporting country confirming the spawn is free from pests and diseases, as required for live plant materials under USDA APHIS regulations

• Verify viability upon arrival with customs; non-viable spawn may be reclassified or denied entry to prevent agricultural risks

• Label packages clearly as 'mushroom spawn for propagation' to avoid confusion with food products under Chapter 7
