What DAP told you might be true...
TJM products all drop shipped from TJM USA in Knoxville, TN, for all of North America. I've heard rumors of them closing down and TJM USA's web site is gone. So if they are indeed gone then TJM products are not available in the US anymore...
You can/could buy TJM bumpers directly from TJM's warehouse in Knox. If you want to try here is some contact info:
