Tevila – Disposable Aluminum utensils

Igros Moshe (YD III #23) Question: Do disposable one time use pans require tevila if used more than once?Answer Something which is not durable and exists only for a short time does not become impure. Therefore these pans which can not be used more than three times can not become impure. It is a problem only for very inexpensive utensils which are disposed because they are so inexpensive. Therefore they don’t need tevila.
