US customs has decided that people/companies in the US are avoiding tariffs by "importing computer components through Canada" ... even if they are over 30 years old. I (and others I know) in Canada have had quite a few problems (just over the last two months) shipping computer components and documentation to the US. My last eBay buyer spent quite a bit of time trying to convince US customs they were not trying to avoid tariffs... [these materials were well over 25 years old] I wanted every Canadian List member to know that if you indicate the contents of the package to contain computer parts/manuals then, no mater how old, these items could be held up in customs or rejected if you don't provide contact info to customs. (customs doesn't seem to have a clue that *old* computer parts fall outside their tariff issue). Since computer parts are "electronic boards/parts" and manuals/documentation can fall under "books" I recommend describing items as such. Shipping whole mini computers are another issue. Generally, make sure both phone numbers are on the parcel so US customs can contact the shipper/buyer immediately with their concerns. Good luck! john PDP-8 and other rare mini computers http://www.pdp8.com
