Be Bound To Do vs. Bound For Somewhere
Be Bound To Do vs. Bound For Somewhere separates two distinct Oxford-documented senses. Bound to do/be expresses certainty or likelihood, while bound for + destination describes travel toward a place. The guide keeps those senses separate from legal or duty-bound uses.
Bound to do/be means certain or likely to do or be something; bound for + place means travelling, or ready to travel, toward that destination.

Quick tests
Certainty-or-destination test
Does “bound” express expected occurrence, or movement toward a destination?
If yes: Use “bound to + verb” for certainty/likelihood.
If no: Use “bound for + place” for destination.
Caveat: Legal, contractual, or other “bound” senses are outside this narrow contrast and should not be forced into either pattern.
Examples
Delays are bound to happen occasionally.
“Bound to” expresses a strong expectation.
The train is bound for the coast.
“Bound for” identifies the destination.
“Bound to” and “bound for” are not interchangeable because they encode different senses.
The first marks expectation; the second marks destination.
Further guidance
Core difference
Oxford gives bound to do/be for certainty or likelihood and bound for a place for direction of travel. These are different senses, not interchangeable complements.
Style Boundary
Do not apply the travel sense to legal or duty-bound uses of “bound,” which Oxford treats separately.
