I can at least explain this a little better since I have had a certified nursery and have sold and imported all kinds of seeds for longer than 20 years. Formally speaking all seeds that come into the US have to come in with a phyto and the person getting the seeds needs to have a general import export license. I have to pay for mine, but a hobby person can get one for free, but you still have to have one. You give the shipper your number and they get the phyto and your good. Most people who just get in a few seeds don't bother with this but if they randomly want to check any package, they will burn your seeds. I don't think it has to do with pepper seeds, this was probably just a package that got checked. Any hobby person who brings in any kind of seeds is always taking a risk that someone will decide to open up your package. Even though this should be random, certain points of entry will have people who are more tough in this regard, ie, in Hawaii. I know the people in San Fran are known for being pretty tight also. NY has so much going through that they would miss more things than they catch. Sometimes the people will send the seeds to you anyway, but after they nuke the package with methyl bromide, which in many cases just kills your plant materials. Tom
