I watched TV show two nights ago "Contraband: Seized at the airport", a 2025 episode. Because they had a bunch of small boxes of same sizes, and a few other queues that made it suspicious, they opened some boxes. Saw labels with BT10, CU50, etc, in 2 part plastic trays for peptides. "research, not for humans.... etc". The CBP agents saw CU50 as Hyaluronic injectables, with no documentation. Because it was going to individual homes/apartments, and not labs, it was seized. "beauty stuff" in their comments. They had a van with a mobile scanner but was more to find drugs. They did not use a Gemini on the CU50 content. They were sending the lot to a centralized CBP lab, to be analyzed. They were inspecting UPS, DHL, mail, etc. I watch each week, and it was the first show where 'injectables' were the subject of inspections. Yes, possibly because the exemption was revoked. But CBP was not familiar with peptides, or the 10 vial trays commonly used.
Unless its a trademark infringement, class A drug, porn material, or whatever is on the hit list for that month, a lot of the freight will make thru. Until the boxes are automatically processed by a scanner, with some AI algorithm, they don't have enough staff to make a dent in the volume the forwarders are shipping. But your home address could be flagged for future imports, has some are reporting on other forums.
