Can I sue a supplier in Vietnam for late delivery causing lost sales, and what proof do I need?

Hi,

Based on your summary, you may have a viable claim against the supplier for breach of contract due to the 6-week delay, even in the absence of a penalty clause. The key will be showing clearly (i) the agreed delivery timeline, (ii) the delay, and (iii) that the delay directly caused the loss of your confirmed customer orders.

From what you’ve outlined, your documentation (contracts, correspondence, invoices, and customer cancellations) should be helpful in claming both breach and causation. You will also need to quantify your losses carefully—typically this would be based on lost profit (rather than total revenue) and any additional costs incurred.

In terms of remedies, the most realistic outcome would be a claim for compensatory damages. Claims for broader or consequential losses are generally more difficult unless foreseeability can be clearly shown. In practice, these matters are often resolved through commercial negotiation.

As next steps, you should collect your evidence into a clear timeline, quantifying your losses, and issuing a formal notice of breach and claim. We can assist with drafting this and developing a negotiation strategy if you wish.

Happy to discuss further.

Dear Clients, if your supplier failed to deliver key materials as schedule causing lost sales, you can inform the supplier the contract cancellation and claim the lost if any.

Thank you for your inquiry. Based on the facts that you had mentioned, a compensation claim against your supplier is potentially viable under Vietnamese commercial law. However, the merits depend on several factors that require careful analysis, including the nature of the supplier's breach, whether any force majeure defence applies, and the strength of your supporting documentation. These are technical issues that cannot be properly assessed without reviewing the full contract and case file. Commercial disputes is limited in two (2) years time from the date of breach.
