Subjects in Ship Chartering: What ‘On Subs’ Means Before a Fixture

During ship chartering negotiations, the parties may agree the main commercial terms while the fixture remains “on subjects.” Those subjects identify approvals or conditions that must still be resolved before the negotiations reach their intended final stage.

Kiev Shipping Ltd helps charterers and shipowners maintain a clear negotiating record, define outstanding subjects and coordinate their timely lifting.

What does “on subjects” mean?

A recap may state that terms are agreed subject to one or more approvals. Common examples include subject charterers’ management approval, subject receivers’ approval, subject stem, subject details, subject board approval or subject satisfactory review of vessel documents.

The precise effect depends on the wording, governing law and surrounding communications. Parties should never assume that every subject operates identically or that an informal phrase has the same result in every negotiation.

Main terms and charter-party details

Negotiations often begin with the main terms: vessel, cargo, quantity, loading and discharge ports, laycan, freight, loading and discharge rates, demurrage and commission. Once these points are aligned, the parties may negotiate the remaining charter-party clauses.

A recap should show which terms are fully agreed, which remain open and which are subject to approval. Mixing unresolved points into an apparently final recap can create unnecessary uncertainty.

Common commercial subjects

Subject stem may allow the charterer to confirm cargo availability or the loading programme. Subject receivers’ approval may be used where the receiver must accept the vessel or schedule. Subject management or board approval refers to internal authority within a party’s organisation.

These subjects should be genuine, specific and time-limited. An undefined approval process can leave the vessel and cargo commercially exposed while the market continues to move.

Vessel approval subjects

Charterers may require time to review the vessel’s particulars, class, flag, age, cranes, hold dimensions, certificates, previous cargoes or port suitability. Project and breakbulk cargoes may also require a preliminary stowage plan, lifting assessment or confirmation of deck strength.

The information required for approval should be requested as early as possible. Owners should know what must be supplied, and charterers should avoid adding new technical criteria only after the nomination is under subjects.

“Subject details” requires disciplined follow-up

Subject details generally indicates that additional charter-party wording remains to be agreed. The parties should identify the base charter-party form and exchange proposed amendments promptly.

Freight alone does not make a workable fixture. Cargo description, exclusions, notices, laytime, bills of lading, loading responsibilities, taxes, sanctions clauses, law and arbitration provisions may materially affect the commercial position.

Set a clear deadline

Every subject should have a definite time for lifting or failing. The deadline should specify the date, time zone and method of communication. This is especially important when the parties, brokers and decision-makers are located in different countries.

If more time is needed, an extension should be agreed before the original deadline expires. Silence should not be treated casually as either approval or rejection.

How subjects are lifted

Subjects should be lifted through clear written communication. The message should identify the fixture and confirm exactly which subjects are lifted. If one condition remains outstanding, that should be stated rather than hidden behind general language.

The broker’s role is to transmit communications accurately and maintain a coherent negotiation record. Brokers should not independently treat a subject as lifted without authority from the relevant principal.

Avoid changing agreed terms while lifting subjects

A message that purports to lift subjects but introduces new commercial conditions may not provide the expected certainty. If a party requests a change, the other side should know that a new proposal has been made and decide whether to accept it.

Clear separation between approval and renegotiation helps prevent later arguments about what was agreed and when.

What happens if subjects fail?

If an approval is refused or a condition cannot be satisfied, the notifying party should communicate that promptly and in accordance with the agreed procedure. Records of the decision and timing should be retained.

The legal consequences can depend on the subject wording, the governing law and the conduct of the parties. Specific disputes should be referred to qualified maritime lawyers rather than resolved through assumptions about market terminology.

Good practice for chartering negotiations

• Use a clear and complete recap.
• Identify every outstanding subject precisely.
• State who controls each subject.
• Set a definite deadline and time zone.
• Record extensions and subject lifting in writing.
• Do not combine approval with unmarked new conditions.
• Preserve the full chain of negotiations and attachments.

Why experience matters in ship chartering

1. Understanding the freight market

Freight levels change according to vessel availability, cargo demand, trading area, laycan and market conditions. Experience helps evaluate realistic freight indications and negotiate appropriate commercial terms.

2. Matching cargo with the right vessel

Different cargoes require different vessel types and technical capabilities. Proper cargo-to-vessel matching is particularly important for project, breakbulk and dry bulk shipments.

3. Charter party negotiations

Freight, laycan, loading and discharge conditions, demurrage and other commercial terms should be clearly agreed before the vessel is fixed.

4. Managing operational requirements

Port restrictions, draft limitations, cargo handling arrangements and voyage requirements may significantly affect the suitability of a vessel and the final chartering solution.

5. Commercial coordination throughout the voyage

Professional chartering support continues after the fixture through communication between cargo interests, shipowners and operators during the voyage.
