"WARNING: Aquaticmagic and other out of country sellers
Just wanted to share my experience with Aquaticmagic, who sells plants on eBay and Aquabid. You may want to think twice before making a purchase.
Back in August I ordered 2 portions of Flame Moss from them on eBay. The package arrived in early September. Instead of my flame moss there was a notice from the USDA saying my shipment had been confiscated due to the import of illegal plant materials, and that I may face further criminal charges.
Yesterday, the USDA sent an officer from "Smuggling Interdiction and Trade Compliance" to my office to interview me (The Flame Moss was originally sent to my office). He quizzed me about my online purchases, had I ordered other plants online, where those plants came from, did Aquaticmagic has a representative in the US, had I ever purchased seeds online, etc etc. At this time it doesn't look like I'll be subject to any fines, although they made it clear it was my responsibility to comply with import regulations and to make sure I had the proper import permits. They seemed much more interested though in trying to figure out how to shut down Aquaticmagic.
Aquatic magic did offer me a full refund after I scanned the notice from the USDA saying the shipment had been confiscated. They responded to my messages quickly. I have no complaints in that regard. They did however mention that a lot of their shipments are being caught at the border and the USDA seems to be cracking down.
So this is just a cautionary tale. If you're buying plants online that might be shipping from out of the country (Aquaticmagic lists their location as Malaysia, but the plants actually shipped out of Singapore), there's a chance the USDA will snag them and they might come and pay you a visit. Just something to keep in mind."
