I was planning to pack a few food items, tea, spice, maybe some noodles, dry items, granola bars where ever they fit, nothing in large quantities (dozen+ candy bars). I see you have to have an IMPORT FORM. They will confiscate these items?
I've been on trips down there were we brought in almost all food for the week including coolers with meat (I think the limit is something like 40 lbs of meat per person max.) You can just declare it on the standard customs form. The charge was minimal. Probably fewer people do it now with airline baggage fees ramping up. You might want to bring some of your grocery receipts if you have them.
