From the B&H site:
"We advertise Kodak film in three types:
* IMPORTED - Film made outside the USA and imported for us. This may also be referred to as "GREY".
* USAW - Film manufactured in the USA for Worldwide distribution.
* USA - Film manufactured in the USA for domestic distribution.
Agfa, Fuji, and Ilford film are made outside the USA. While we offer many of these in "grey” (direct import) and "USA" the primary difference is not where the film came from, but who brought the film into this country.
B&H Photo recognizes that for many professionals, the method of handling the film and its storage conditions during transport are factors of vital importance. Optimum performance is essential for any professional, whether shooting food, fashion or portraits. We know that you need contrast, tonal range, color rendition and saturation to be accurate, reliable and repeatable. We are also aware of the fact that many of our amateur customers devote the same care and consideration to their photography and deserve the same quality. "
FWIW I've always bought imported or gray market film and I've not had any problems.
