Heinz has a best by date of 15 months printed on its ketchup, if I recall correctly, but that is not the same as true expiration. That's just when the flavour/quality may begin to change. It will remain viable for quite a while after that. An unopened bottle probably just won't expire.
Ketchup and chili sauce keep for up to six months if you store them in a 40-degree Fahrenheit or colder refrigerator, but only one month if you keep them in the pantry at room temperature. Barbecue sauce remains good for four months in the fridge and only one month in the pantry.
