How it's used
Used primarily in formal or administrative contexts, such as discussing contracts, memberships, or official appointments. While it is perfectly understood in speech, it carries a slightly professional or serious tone compared to everyday phrasing like 到期. It is rarely used for perishable goods like food, where 到期 is the standard choice.
Examples
His contract expires next month.
Do you know when the membership expires?

Common mistake
Learners often confuse this with 到期, which is much more versatile and can be used for everything from library books to milk. Using 屆滿 for a carton of milk would sound comically formal and out of place.
