Subjects

Meaning

Subjects are conditions attached to an otherwise agreed fixture, such as charterer's approval or vetting, that must be lifted before it is binding.

Also written as Subs, On subs, Subject to

Subjects explained

Typical tanker subjects are “sub charterers' management approval”, “sub vetting”, “sub receivers' approval” and “sub stem” (the cargo being confirmed). Each has a deadline, and the fixture is only clean once all of them are lifted.

Under English law, a fixture “on subjects” may not be a binding contract at all, so either side may still walk away until the subjects are lifted.

Watch out for

Some subjects are pre-conditions to the contract; others are conditions of performance. The difference decides whether a party can walk away, so wording matters.
