Imagine this: you place an order in China worth USD 15,000. The invoice arrives from your Chinese supplier, and the declared value says USD 6,000. For some importers, the first reaction is obvious: lower value means lower duty and lower import VAT. In reality, an undervalued invoice from China is not welcome. It is a risk that can come back at customs clearance, during a later audit, or when authorities start asking how the declared value relates to the amount that was actually paid. And this is the part many buyers underestimate: if that invoice is used for customs clearance, the consequences usually fall on the importer, not on the Chinese factory.
Why do undervalued invoices from China happen?
Before deciding what to do, it helps to understand why this happens in the first place. Not every undervalued invoice comes from the same type of situation.
- Sometimes the importer asks for it directly, hoping to reduce duty and VAT.
- Sometimes the supplier does it on their own because they think they are being “helpful” or because they assume this is what the buyer wants.
- And sometimes it is simply a mistake: the supplier enters the unit price instead of the full order value, uses the wrong quantity, or works from an outdated quotation.
On paper, all of these cases may look similar. In practice, they are very different. A genuine mistake should be corrected immediately. A deliberately undervalued invoice should not be used at all.
What can happen if goods are cleared on an undervalued invoice?
If customs authorities decide that the declared value is too low, they can reject it and reassess the shipment. That may mean additional customs duty, additional import VAT, and interest. The more obvious the difference between the real price and the invoiced price, the more difficult it becomes to explain the discrepancy as a simple oversight.
Authorities do not rely on the invoice alone. They may compare the declared value with payment records, commercial contracts, commercial correspondence, product specifications, and the values of similar goods. If the declared value does not look commercially credible, customs can ask questions very quickly.
That is why an undervalued invoice is not just a paperwork issue. It creates a credibility problem across the whole import file.
Two common scenarios – and two very different outcomes
Scenario 1 – The supplier made a mistake, and you catch it before clearance
This is the best-case scenario. You notice that the invoice value does not match the purchase order, quotation, or bank transfer. In that case, the right move is simple: go back to the supplier immediately and ask for a corrected invoice or a replacement commercial invoice with the proper value.
If the goods have not yet been cleared, the issue is usually manageable. Once the corrected document is sent to your customs broker in time, the shipment can move forward on the proper value.
This is exactly why invoices should be reviewed as soon as they are received, not only when the cargo is already at customs.
Scenario 2 – The invoice was undervalued on purpose
This is where the real risk starts. If the importer knows the invoice does not reflect the real deal and still uses it for customs clearance, any short-term saving can easily turn into a much bigger problem later. Even if the first few shipments pass without questions, the issue may surface on a later shipment, in a post-clearance review, or during a tax or customs audit.
The worst part is that the timing is unpredictable. The problem may not appear at the shipment where the invoice was first used. It may show up months later, when the importer has already built a pattern of documentation that no longer makes sense when reviewed as a whole.
What should you do if you receive an undervalued invoice?
If it is a supplier error
Don’t wait and act quickly. Contact the supplier, point out the discrepancy, and ask for a corrected invoice or replacement commercial invoice. It is best to do this in writing, by email or WeChat, so you have a record showing that you identified the issue and requested the correct document.
If the goods are already in transit or close to customs clearance, pass the corrected invoice to your customs broker immediately. The earlier the issue is fixed, the easier it usually is to manage.
A well-drafted commercial contract reduces the risk of this kind of problem in the first place, because it clearly defines the order value, payment terms, and documentary obligations.
If the invoice was undervalued knowingly
In that case, the safest move is to stop before the goods are cleared. If the invoice does not reflect the real transaction value, ask for a proper invoice and clear the shipment using accurate documents. In practice, that is almost always cheaper than dealing with a challenge later.
If you are not sure how to structure import documentation correctly or how customs value works in practice, we can help you understand the process step by step. And before placing another order, it is often worth checking the supplier more carefully. Supplier verification helps you assess whether you are dealing with a reliable company.
FAQ – common questions about undervalued invoices from China
Is an undervalued invoice from China illegal?
The key issue is not the invoice by itself, but how it is used. If a document that does not reflect the real transaction value is used for customs clearance or tax reporting, that creates a legal and financial risk. In EU imports, customs value is generally based on the actual price paid or payable, not on a number inserted for convenience.
Customs has challenged the value of my goods. What now?
You need to prepare a full set of documents showing the real transaction: commercial contract, payment confirmation, supplier correspondence, quotations, and product documentation. At this stage, it is usually wise to work closely with your customs broker or customs adviser.
Can I legally reduce import costs when buying from China?
Yes, but not by lowering the invoice value artificially. Legal methods include proper HS/CN classification, the right Incoterms setup, and clean supporting documentation for the import structure.
The supplier issued a lower invoice without telling me. Do I have a claim against them?
You have a basis to demand the correct commercial document. That is the first and most important step. Any wider claim for losses will depend on the contract, the damage you suffered, and whether the supplier’s documentary obligation was clearly defined.
Is the customs broker responsible if the invoice value was too low?
In most cases, the broker works on the basis of the documents provided by the importer. If the broker had no clear reason to believe the documents were inaccurate, the main responsibility still sits with the importer. That is why reviewing the invoice before it reaches customs is so important.
