I would agree with Dave Green that the responsibility for meeting legal obligations regarding the crossing of international borders would have to rest with those persons who are engaged in international trade. While it would be convenient to have a ready-made handout available explaining the applicable laws and regulations, keeping such an information sheet current would be a neverending task. And, I assume the current regulations are available via the internet? There is a related concern though, which could affect both domestic and foreign dealers attending COA conventions. The conventions are held in a variety of locations, and each state or city may have its own regulations concerning retail sales. Here in Rhode Island you can't sell balloons at a parade, or hotdogs at the park without a vendor's permit. A permit is also required to run a flea market, an auction, a yard sale, or various other kinds of revenue-generating activities. Private yard sales and garage sales are run all over the place with no permits, and no problems. But failure to acquire the necessary permit for a public event can result in confiscation of your inventory, and possible fines as well. Such permits can be acquired for a year, for a week, or for a single day, depending on your intent. Managers of large-scale, ongoing flea markets obtain blanket permits which cover all the dealers who sell on their property on a given day, and are also required to have liability insurance - and presumably pass along the costs in the per table fee charged to individual dealers. SO - my question is - Does COA investigate state and local ordinances, as they pertain to silent auctions, voice auctions, and dealer bourses, as a routine part of pre-conference preparations? Does COA obtain any required permits or licences? And can dealers assume that what they are doing at the convention is legal from the viewpoint of the state and city in which they are doing it, and that they can sell their wares without risk of confiscation and/or fines by local authorities?
