Q: Do raw nuts require certification for Passover?
A: Raw nuts in their shell do not require Passover certification. Shelled nuts that list BHA or BHT (preservatives) in the ingredients require special Passover certification.

Q: What coffees are acceptable for Passover?
A: All regular ground coffees are acceptable for Passover use when bearing an OU.
Decaffeinated coffee: Coffee is often decaffeinated by means of ethyl acetate, which is derived from either kitniyot or chometz. Therefore, decaffeinated coffees are not acceptable for Passover unless specifically marked for Passover or found in our Passover Guide and on oupassover.org under the heading of products certified for year round use and Passover.
Instant coffees often contain maltodextrin, which is derived from either from corn (kitniyot) or wheat (chometz). Therefore, all instant coffees require special Passover certification unless explicitly mentioned in our Passover Guide and on oupassover.org under the heading of products certified for year round use and Passover.

Alternatively one can find this information in ‘The Kashering Primer – Passover 2014’ article located on the homepage of oupassover.org).
