The Dept of agriculture USDA has strict guidelines for accepting import material germplasm within the continental US. The simple act of accepting seed, albeit as harmless as it may seem can decimate a producing community and bring the economy to it's knees. As Dan has clearly stated, to become a clearinghouse to accept seed and then re-distribute is restricted and the fines for this are quite hefty and imprisonment or both if caught. http://www.aphis.usda.gov/ppq/permits/plant_products.htm
