China is on customs shit list.
For me my experience and you can take it for what it was worth.
Life was great prior to Dec 2019, for years my packs flew through customs NYC in 48 to 72hrs, Chicago often times a seven days. They weren't opened, they were just sent without problem
Late 2019, every pack suddenly spent at least 30 days in customs, one pack spent 45 days another with thousands of caps spent 60 days. These were all open inspected, container seals cut and probably spec'd, they packed everything up and sent it anyway. Last pack of raws had FDA written on the outside.
I use reshippers from here on out.
The holy grail is large volume domestic raws, but isn't that a pain in the ass for the source and it has to be stressful.
We need better stealth, we need a shipping off point other than China, we need to be able to evade x-ray.
