Sending samples to customers is a routine part of international trade. But many people have learned the hard way: the goods are shipped, the money isn’t collected, and you may even have to pay for the return shipping—losing twice on one deal.
This situation is actually quite common, and in most cases, it can be avoided in advance. The key is whether you’ve thought about the risks beforehand.

1. Why do customers refuse to pay shipping?
Before blaming the customer, it’s worth understanding that most cases follow a pattern. Common reasons include:
1) Shipping cost exceeds expectations
International express shipping is expensive by nature. Many customers are used to local logistics or freight forwarder quotes. When they see the final bill, they’re shocked: “Why is it so expensive?”—and simply refuse to pay.
2) Dissatisfaction with the sample
After receiving the sample, the customer may feel it doesn’t meet expectations, or they’ve already found a better supplier during the waiting time. Their thinking becomes: “If I’m not going to use it, why should I pay for shipping?”
3) Additional charges arise
Such as duties, customs clearance fees, remote area surcharges, etc. Some customers are unaware of these in advance. When the bill arrives and it’s more than just shipping, they resist paying.
4) Trying to take advantage
No need to over-explain this—some customers simply want to test if they can avoid paying altogether.
No matter the reason, one thing is clear: the courier will always go after the sender first. By the time it gets to that point, regret won’t help.
2. How to prevent this in advance?
Instead of dealing with disputes later, it’s better to block the risk from the start.
Method 1: Let the customer arrange the shipment
This is the cleanest approach. You only provide the pickup address, and the customer books the courier through their local website.
The advantage is obvious: the cost, billing, and responsibility are all on the customer’s side. Even if they refuse to pay, it’s between them and the courier—not your problem.
Method 2: Clarify responsibilities before shipping (and keep proof)
Don’t rely on verbal agreements. Always confirm via email or chat, and clearly state:
“If the consignee refuses to pay shipping or related charges, all resulting costs shall be borne by the consignee.”
Some people feel awkward saying this, but it actually protects both parties. If you don’t make it clear, the other side may “pretend not to know.”
Method 3: Provide a shipping cost estimate in advance
Even if it’s not exact, give a reasonable range, such as:“Estimated shipping cost: USD 80–120, subject to the courier’s final invoice.”
This helps set expectations and prevents negative reactions when the bill arrives.
Method 4: Screen your customers—don’t offer COD to everyone
For new clients, poor communicators, slow responders, or those aggressively pushing prices, it’s safer to require prepaid shipping.
Simply put: trust has levels. Not every customer is worth taking the risk for.
3. What to do if it already happened?
If you do encounter this situation, stay calm and handle it case by case.
1) If the shipping cost is low, prioritize saving the relationship
Contact the customer to understand the reason, then offer solutions, such as:
You cover the excess amount
Split the cost
Deduct it from future orders
Often, customers aren’t completely unwilling to pay—they just feel it’s “not worth it.” Give them a reasonable option, and the issue can often be resolved.
2) If the sample value is high, do the math first
Don’t act emotionally. Calculate whether it’s more cost-effective to return the goods or to abandon them.
At the end of the day, business is about profit—not pride.
3) Mark and manage risky customers
Any customer who has caused issues should be recorded. For future cooperation:
Either require full prepayment
Or stop working with them altogether
Similarly, for high-risk countries or markets, you can adopt a unified rule: prepaid samples only.
In the end, COD refusal isn’t about bad luck—it’s about poor risk control.
Set clear rules upfront and filter your customers early, and you’ll find that most of these problems simply disappear.
