I hesitate to say that "Chinese goods stink", but we have had a couple of recent orders from legitimate vendors with this problem on Chinese-made goods.
1. My wife ordered a medium-sized wheeled suitcase before a trip to Europe (before the plague). On its first outing, the security officers at Zurich airport stopped her politely after their chemical sniffing equipment responded to the chemical odor from the new case. (This was not an over-reaction, since even with my bad sinuses I could smell it, as well.)
2. From another vendor, she ordered a cotton flannel-print comforter cover (bedding). Out of the box, it didn't smell too bad, but with it pulled up to our noses it was obvious. We aired it out, washed it several times, etc., but the smell still lingers (presumably from the print inks). A previous similar flannel cover (same vendor) from Portugal had no odor whatsoever.
I don't know if the excess smell is directly the fault of the manufacturing process or the long trans-Pacific shipment in a container.
