A buyer who first questions a cargo at the discharge port is negotiating from the weakest position available. The goods have crossed the sea, the letter of credit has most likely been honoured against compliant documents, and the dispute has shifted from “this is not what we ordered” to “show us it was different when it was loaded”. That second argument is expensive to win. It is also, in most cases, one nobody needed to have.
What decides the outcome is three questions answered at the moment of ordering — and left open in most enquiries we receive: what is being measured, who does the measuring, and at which port the result becomes binding.
Parameter, method, tolerance — always together
“Urea 46” describes a product family, not a contract. A usable specification states each parameter alongside its test method and its limit: total nitrogen at least 46.0% by weight, biuret no more than 1.0%, moisture no more than 0.5%, and a size distribution expressed as a percentage passing a named sieve. Where the cargo must also meet the relevant Indonesian national standard (SNI), say so in the contract rather than assuming the seller knows. Two laboratories using two different methods on one sample can disagree by more than the tolerance in dispute.
Every category has its equivalent. Rice is described by broken percentage, moisture, chalky and damaged kernels and milling degree. Reinforcing bar is described by grade and standard together, because yield strength alone tells a contractor nothing about ductility or bend behaviour. Caustic soda is described by assay, iron and chloride limits and physical form — flake, pearl or liquid.
Put the surveyor's name, scope and fee in writing
An independent inspection company at the load port turns a disagreement into a document. Three things belong in the contract: who appoints it, what it is asked to do, and how its fee is shared. “Inspection” on its own is not a scope. The scope is the sampling method, how many samples are drawn and from where, whether sealed reference samples are kept and for how long, and which analyses are run.
- The appointing party — buyer, seller, or one name chosen jointly from an agreed list.
- Whether the surveyor's certificate is final and binding on both sides or merely indicative.
- How long sealed reference samples are retained, and the window in which either side may call for a re-test.
- What happens when a result is out of tolerance: rejection, a price adjustment on an agreed scale, or a replacement parcel.
Choose the port where quality is fixed
Fixing quality at loading and quantity at discharge is a sensible and widely used arrangement — provided someone actually chose it. Cargoes change on the voyage. Fertilizer is hygroscopic, and the humidity of a hold crossing the Java Sea or the Strait of Malacca in the wet season is not the humidity of the conveyor that loaded it. Handling generates fines, and moisture moves through a stow. A contract that says nothing leaves each side to rely on whichever certificate suits it.
Where transit change is a genuine risk, the cleaner answer is rarely to argue over the point of determination. It is to write tolerances that anticipate the change — an allowance for moisture, one for fines, and a franchise below which no claim can be raised at all.
Read the documents against the credit
A whole class of problem has nothing to do with the goods. A correct certificate of analysis that names the product differently from the commercial invoice, is dated outside the presentation period, or comes from an issuer the letter of credit does not recognise will be refused by the bank, however good the cargo. Check the credit's documentary conditions clause by clause as soon as it is issued — while an amendment is still a quick request rather than a delay.
There is nothing clever in any of this. It is a list, worked through before the goods are loaded, and it costs a handful of emails. The alternative is a claim file and a strained relationship.
