No one would argue that eliminating illegal trade in elephant ivory is a worthwhile goal- Many pipemakers in the US use "Pre-ban" ivory for shank extensions or stem details- purchased from dealers who go to great pains to make sure that what they sell meets the rules. Pre-ban means that the ivory was imported prior to 1990 or is antique. In my case, I have a couple of pounds of ivory I bought in the early 80's- I've been leery of incorporating it in many of my pipes because I thought this rule would be coming. An executive order was signed yesterday that when implemented will effectively ban the domestic sale of all ivory from any source across state lines. If I'm reading it correctly, it will also make it nearly impossible to use Fossilized Mammoth ivory because it can be very difficult to prove the provenance. Think it doesn't affect you? If you own an estate pipe from any artisan carver with any ivory detail , you better enjoy it, because it will be illegal to sell across state lines or inside a state if you don't have documentation proving that the ivory detail was from pre-ban ivory...An interesting exemption allows one pair of tusks a year to be imported as trophies by sport hunters- sounds like some lobbyist worked really hard on that detail Executive Order Banning Ivory Trade
