A buyer who discovers a quality problem at the discharge port has already lost most of their leverage. The cargo is on the wrong side of the ocean, the letter of credit has probably been paid against clean documents, and the argument has quietly changed from “this is not what I bought” to “prove it was not like this when it left”. That is a much harder case to make, and it is almost always avoidable.
The decisive work happens at the point of order, in three clauses that most enquiries leave vague: what exactly is being measured, who measures it, and where the measurement becomes binding.
Specify the parameter, the method and the tolerance
“Urea 46%” is not a specification. A workable one names the parameter, the test method and the tolerance in the same breath — nitrogen content minimum 46.0% by weight, biuret maximum 1.0%, moisture maximum 0.5%, granulometry with a stated percentage passing a stated sieve. Where an internationally recognised method exists, cite it. Two laboratories testing the same sample by two different methods can produce results that differ by more than the tolerance you were arguing about.
The same discipline applies across categories. For milling wheat it is protein on a stated moisture basis, test weight, falling number and foreign matter. For rebar it is the grade and the standard together — ASTM A615 Grade 60 or BS 4449 B500B — because the yield strength alone does not tell a fabricator what elongation or bend performance to expect. For caustic soda it is the assay, the iron and chloride limits, and the physical form.
Name the surveyor, and name who pays
An independent inspection company appointed at the load port converts an argument into a document. The three points to settle in writing are the appointment, the scope and the cost split. Scope means more than “inspection”: it means sampling method, the number and location of samples, whether sealed counter-samples are retained and for how long, and which analyses are performed.
- Who appoints the surveyor — buyer, seller, or a jointly agreed name from an agreed shortlist.
- Whether the certificate is final and binding on both parties, or indicative only.
- Retention of sealed counter-samples, and the period during which a re-test can be demanded.
- The remedy if results fall outside tolerance: rejection, a price allowance against a stated scale, or replacement.
Decide where quality passes
Quality determined at the load port and quantity determined at the discharge port is a common and workable split, but it has to be chosen rather than assumed. Bulk agricultural and mineral cargoes change in transit: moisture migrates, fines are generated by handling, and a hygroscopic fertilizer will behave differently after three weeks in a humid hold than it did on the conveyor. If the contract is silent, the parties are relying on whichever certificate happens to favour them.
Where the physical risk of transit change is real, the answer is usually not to fight over the point of determination but to write a tolerance that reflects it — a moisture allowance, a fines allowance, and a franchise below which no claim arises at all.
Check the documents against the credit, not against the cargo
A separate and frequently painful category of problem has nothing to do with quality and everything to do with wording. A certificate of analysis that is accurate but describes the goods differently from the invoice, or is dated outside the presentation period, or is issued by a party the letter of credit does not name, will be refused by a bank that has no interest at all in whether the cargo is good. Documentary requirements should be read line by line at the time the credit is issued, while amendments are still cheap.
None of this is exotic. It is a checklist, applied before the goods move, and it costs a few emails. The alternative is a claim file.
