Manufacturer’s Warranty – where does marketing end and the law begin?

A manufacturer’s warranty is one of the most commonly used tools for building trust in a product. In marketing communications, it is often presented as an additional safeguard for the customer, frequently suggesting enhanced quality or durability of the goods offered. In practice, however, its legal significance and its relationship with the seller’s statutory liability are not always properly understood.

A warranty is voluntary in nature. This means that the manufacturer (or another warrantor) independently determines its scope, terms, and duration. It may cover various undertakings – from an obligation to repair, through replacement of the product, to a refund – but always within the limits set out in the warranty statement.

Crucially, in consumer relationships, a warranty operates alongside the seller’s statutory liability for conformity of the goods with the contract. As a rule, it neither replaces nor limits this liability – the consumer remains free to choose the legal basis for pursuing their claims.

In practice, this means that:

• a warranty arises from the warrantor’s declaration and is shaped by its content;
• the seller’s liability derives directly from statutory provisions on conformity of goods and is mandatory in consumer relationships;
• the scope of remedies under each regime may differ – in some cases more favourable under the warranty, in others under statutory liability;
• reliance on a warranty does not preclude the consumer from asserting claims against the seller under statutory liability (and vice versa).

From a business perspective, the proper structuring of warranty terms is of key importance. The warranty document should be clear, precise, and consistent with marketing communications. Any discrepancies between the promise and the actual scope of protection may lead not only to customer disputes, but also to allegations of misleading practices.

It is also worth noting that in B2B transactions (i.e. outside consumer relationships), the seller’s liability may be modified to a much greater extent or even excluded. This increases the importance of precise defining contractual liability and any applicable quality guarantees.

As in many other areas of law, a clear distinction between different bases of liability and conscious risk management are essential. Well-drafted warranty terms, combined with a coherent complaints-handling policy, not only reduce the likelihood of disputes but also enhance a company’s credibility in the market.

It should also be borne in mind that issues relating to product liability rarely arise in isolation; they are often linked to earlier decisions regarding the framing of warranty terms and the conditions under which the product is offered. Experience shows that the greatest predictability can be achieved when these aspects are properly addressed at the stage of bringing the product to market, rather than only at the point of handling a customer complaint.
