Changes to the African elephant ivory regulations went into effect on July 6th, 2016. This is a federal regulation effecting sales OVER state lines.There are 2 categories that your elephant ivory falls into, either antique (100 + yrs of age) or de minimis. For my purposes here I will only discuss de minimis. To qualify for the de minimis exception, manufactured or handcrafted items must meet all of the following criteria: • The ivory was imported into the United States prior to January 18, 1990, or has a (CITES) pre-Convention certificate with no limitation on its commercial use; • If the item is located outside the United States, the ivory was removed from the wild prior to February 26, 1976; • The ivory is a fixed or integral component or components of a larger manufactured or handcrafted item and is not in its current form the primary source of the value of the item, that is, the ivory does not account for more than 50 percent of the value of the item; • The ivory is not raw; • The manufactured or handcrafted item is not made wholly or primarily of ivory, that is, the ivory component or components do not account for more than 50 percent of the item by volume; • The total weight of the ivory component or components is less than 200 grams • The item was manufactured or handcrafted before the effective date of this rule. ( July 6, 2016) The only type of ivory regulated under this final rule is African elephant ivory. Nothing in this final rule impacts a person's ability to own or possess legally acquired African elephant ivory. My understanding of this new law is that I can legally add my artwork to your ivory handled knives, however it is possible that the addition of my work could disqualify your knife from the de minimis exemption if the value of the ivory then surpassed 50% of the overall value of the knife. You can ship me your knife for the addition of my work, since I am not adding any material, only my artwork, and I can ship it back to you without violating any of the statute. Shipping over state lines for this reason is allowable. I will not sell any elephant ivory items over state lines after July 6, 2016.
