It's not uncommon for goods sold in different territories under the same brand name to have different formulations, due to things like climate as well as different legal requirements. There were several cases in the 1980's where UK companies were able to prevent grey imports of stuff having the same brand name (not fakes, but made by foreign subsidiaries of the UK company for their local markets) because the imported stuff wasn't suitable for use in the UK. Canadian Castrol GTX motor oil comes to mind. Reflecting the temperature extremes of the Canadian climate, Canadian GTX was only manufactured in specific summer and winter formulations rather than the single multigrade product sold in the UK, and its use in the UK could have resulted in engine damage.
