I've taken those tins over to both Lebanon and Philippines before, and never any trouble

Only thing I'd bear in mind, is that UK chocolate (Being amongst the best in the world, not like that Belgian or other continental crap) is designed for cool climates and won't cope well at all if it goes to phils. I found this out after taking a load of choc with me when I went over in September, and it turned to mush.
ps, let them take the toffee pennies, they are disgusting! That's why small shopkeepers never let you put Quality Street in the pick and mix, because they knew they would be left with those cheap nasty toffees hardly anyone liked
