No customs form as I’m in the USA. When buying from UK, the seed co fills out the customs form on package indicating something like clothes or toys or whatever. I personally never had my seeds confiscated over 15+ years but I know of a couple folks who did. They asked for replacement seeds from company and got them. The bubble envelope had my name and address and the return address said nothing about the company.Was a customs form needed? Curious as to what they put on there for seed packs ina bubble envelope.
