A mate's receipt is the receipt issued by a ship's officer, usually the chief officer, acknowledging that cargo is on board and describing its apparent order and condition. Remarks made on it are normally carried across to the bill of lading as clauses. A bill without such remarks is a clean B/L; one stating that the cargo appeared defective is claused, and the difference has real commercial consequences.
What is the purpose of a mate's receipt?
The mate's receipt is the first document evidencing that cargo has actually been taken on board. On completion of loading, the officer records the quantity received and the cargo's apparent condition, and the bill of lading is in most cases prepared on the basis of it.
Because the carrier is generally expected to deliver cargo in the apparent condition in which it was received, recording visible defects at loading is a natural form of protection for the ship.
What kinds of remarks end up as B/L clauses?
Remarks depend on the cargo and normally concern its apparent condition. Typical examples encountered in the field include:
- Partly or heavily rusty steel, or wet before shipment
- Edge damage, dents or bends on coils and plates
- Torn, re-sewn or stained bags
- Damaged crates, broken pallets or missing packaging
- Rain during loading or bulk cargo appearing wet
- Quantity not verified by the vessel

Why does a clean or claused B/L matter?
Under letters of credit, banks generally require a clean on board bill of lading, so a claused bill can delay or complicate payment to the seller. For the buyer, a clause signals that the cargo was already defective when shipped.
On the other hand, leaving a genuine defect off the bill exposes the carrier. Issuing a clean bill against a letter of indemnity is seen in the trade, but it is widely recognised that this can prejudice P&I cover, and such decisions should always be reviewed with the parties' own legal advisers.
How do clausing disputes usually arise?
Most disputes are about wording. A shipper may object to surface rust seen on a few units being described in a blanket clause covering the whole parcel, while the ship may maintain that the condition was widespread.
What settles the argument is a concrete record of which units were affected, to what extent and when. Observations logged by unit number or by hold and backed by dated photographs help define the scope of a clause in a reasonable way.
Quantity remarks are a separate battleground. For bulk cargo, the B/L figure is often based on shore scale or draft survey results; if the ship cannot verify it, the bill may carry weight-unknown wording. Recording any difference between ship and shore figures becomes important if a shortage is alleged at discharge.
How can clausing risk be reduced during loading?
Clausing risk cannot be removed entirely, but separating defective cargo before it reaches the ship and keeping orderly records reduces it considerably.
- Check cargo condition on the quay or in the warehouse before loading
- Set aside or replace damaged units rather than shipping them
- Close hatches promptly when rain starts with moisture-sensitive cargo
- Share observations with the ship's officer during the operation, not afterwards
- Photograph defective units together with their numbers and positions
Why are rust and wetting clauses on steel so sensitive?
Steel products often wait in open storage, so some atmospheric surface rust is normal. Disputes usually turn on how that normal rust is distinguished from rust caused by wetting or affecting the product's usability, which is why clauses such as partly rusty, rust spots or wet before shipment are used with different meanings.
To indicate whether wetting is from fresh water or seawater, the silver nitrate test is widely used in the field as a preliminary check for chlorides on the surface. Observations of this kind made before loading help show the cargo's condition at shipment if wetting is disputed at discharge.
What is the independent surveyor's role in clausing?
The surveyor does not write clauses or issue bills of lading; that authority lies with the carrier. The surveyor's role is to observe and record the apparent condition of the cargo independently and make those records available to the appointing party, giving everyone a factual reference when the scope of a clause is debated.

Frequently asked questions
How does a mate's receipt differ from a bill of lading?
A mate's receipt simply acknowledges receipt of the cargo on board. A bill of lading evidences the contract of carriage, acts as a receipt and, in most cases, is a transferable document of title. The B/L is normally issued on the basis of the mate's receipt.
Is 'said to contain' a clause on cargo condition?
Wording such as said to contain or shipper's load and count records that the carrier has not verified the contents. As it does not state that the cargo is defective, it is generally not regarded as a condition clause in the classic sense, although interpretation can vary.
Can a clause be removed once it has been made?
If defective units are replaced or the defect is remedied, the parties can ask for the clause to be reconsidered. The final decision rests with the carrier issuing the bill of lading.
