The most common and costly mistake is treating arrival as a logistics event rather than an evidence event. Buyers move goods into inventory, unpack without recording, resell part of the shipment, or mix it with existing stock — and once that happens, proving the original condition becomes difficult.
If something looks wrong, stop unpacking. Before moving or using the goods:
Read the contract first. A pro forma invoice or sales contract usually carries a defect remedy clause covering what counts as a defect, the reporting window, and what the supplier owes. Some windows run as short as seven days from arrival, and missing one weakens a position that would otherwise be strong.
If testing or a full count will take longer than the window allows, send an initial written notice immediately that reserves your position, then follow it with detailed findings. Months of silent investigation creates a timeliness dispute that is entirely avoidable.
They look similar on arrival and lead to different remedies and different counterparties:
| Problem | What it means | Who it goes to |
|---|---|---|
| Defective goods | The correct product with quality problems — leaking seams, failed zippers, torn anchors | The factory |
| Wrong goods | Correct quality, but the model, size, material, colour, configuration, packaging, or labels do not match what was agreed | The factory — and this is a contract breach even if the product works perfectly |
| Transit damage | Damage from handling or water ingress in transit, typically in crushed or wet cartons | The carrier or insurer |
The fault line between factory and freight is usually visible in the pattern. A supplier-caused defect is consistent — the same flaw, in the same place, spread evenly through the batch, inside cartons that arrived intact. Transit damage clusters by location in the container and comes with damaged packaging.
This distinction changes outcomes more than any other single factor. A complaint says the quality is bad. A claim is written, dated, and quantified. It should contain:
One message, factual, unemotional. Attaching an inspection report and highlighting the specific findings shifts the exchange from relationship negotiation to evidence-based commercial resolution — which is the ground a reasonable factory can act on and an unreasonable one finds hard to argue with.
For waterproof bags specifically, the most persuasive evidence names the failure point rather than the symptom: water entering at a zipper end, a base seam, a roll-top junction, or a logo patch. The methods for identifying that are set out in the guide to evaluating a waterproof bag sample.
The realistic list is short, and which fits depends on the defect rate and whether the goods are saleable:
Be specific about which one you want. A claim that asks for "a solution" invites a counter-offer; a claim that asks for rework of a stated quantity by a stated date invites a yes or no.
Worth being direct about this, because it changes how buyers should spend their energy. Almost no bulk buyer sues a factory over one bad batch — legal costs exceed the value of the goods. What a buyer actually holds is the unpaid balance, the next purchase order, and the supplier's interest in a repeat customer.
Evidence turns that leverage into a number; anger does not. Two practical implications:
Where a dispute does escalate, the deciding issue is rarely who is right in principle — it is whether the contract, invoice, payment records, inspection material, and correspondence tell one coherent story. Courts distinguish sharply between serious breach, minor defects, late objections, and unclear evidence. That is another reason the first hour matters.
If the supplier proposes repair, replacement, or return, agree the terms before the goods move. The arrangement should cover custody, inspection access, freight, customs, deadlines, and what happens if the repair fails or the supplier continues to deny liability. Shipping goods back on a verbal promise removes both your evidence and your leverage in one step.
Every claim mechanism above is a recovery from something that should have been caught earlier. The controls that prevent arrival disputes:

Q: The shipment looks wrong. What do we do first?
A: Stop unpacking and document. Photograph cartons with shipping marks intact before opening, record the unpacking, compare against the purchase order and approved sample, and count how many units are affected out of how many inspected. Moving goods into stock or reselling part of the shipment makes the original condition hard to prove.
Q: How long do we have to report a problem?
A: Check the contract, because windows can be as short as seven days from arrival. If a full assessment will take longer, send an immediate written notice reserving your position and follow it with detailed findings — silent investigation creates an avoidable timeliness argument.
Q: Is this a factory problem or a freight problem?
A: Look at the pattern. A factory defect is consistent — the same flaw in the same place, spread evenly through the batch, in cartons that arrived intact. Transit damage clusters by container position and comes with crushed or wet packaging. The two go to different parties, so separate them before writing.
Q: What remedy should we ask for?
A: Name one. Rework, replacement, a credit note against the next order, a price reduction, or a refund — each fits a different situation, and a credit note is often the fastest to agree because it costs the factory less cash while giving you real value. Asking for "a solution" invites a counter-offer.
Q: Should we threaten legal action?
A: Rarely useful as an opening move. Legal costs usually exceed the value of one batch, and your real leverage is the unpaid balance, the next order, and the supplier's interest in keeping a repeat customer. A documented, quantified claim converts that leverage into a number.
Q: How do we avoid being in this position at all?
A: Hold a signed gold sample, write acceptance criteria and a defect remedy clause into the order, track production milestones, and tie the balance payment to a passed pre-shipment inspection. Problems found in the factory are cheap to fix; the same problems found in your warehouse are not.
If you want acceptance criteria, inspection points and a defect remedy clause written into the order rather than discovered later, send your specification and we will quote against them — submit an inquiry.
