Don't confuse with

必着 means a document or item must physically arrive by a deadline, while 必達 means a goal or target must be achieved or delivered, and the two are easily confused because they share the kanji 必.
必ひっ携けい sense 1
必着 is about something arriving by a set date, whereas 必携 means an item (like a reference book) is essential to carry with you, and learners often mix up the two because both start with 必.

Etymology

Compound of 必 (certainly, must) and 着 (arrive, wear). The meaning 'must arrive' is the primary sense; the 'must wear' sense is a semantic extension from the idea of something being attached to the body.
