I buy a LOT on eBay from overseas sellers. Many of the Chinese sellers use some bulk shipper that moves the package close to destination, then hands them over to the post office for the last mile. They're generally pretty reliable, but SLOW. Frequently a month or a month and a half for delivery. I don't know how Shanghai ships directly, but slow shipping would be my biggest concern, not as much handling and xray since its likely going through the same scans that B&H containers go through at customs. I have a lens board adapter that I ordered a month and a half ago. That may be the first one that will be lost (stuff ordered later and shipped with the same shipper have passed it and been delivered already.) But that also why I prefer to order stuff like that through eBay, so I get the eBay protection, in addition to PayPal protection. For US buyers, import duties are a non issue unless you are buying over $800 worth of film (and even then, customs rarely steps in, even when I bought a $1500 Bronica GS-1 kit from Japan.) But...
There has been some discussion in the past that CatLabs 80 is the same film. If you order direct from CatLabs, I believe it is shipped from the US, plus it is frequently available from Freestyle and B&H. While they don't have 220, they may be persuaded to add it if there is interest.
