What EU Consumer Guarantee Law Means When You Resell a Used Phone

Buying used phones wholesale is a B2B transaction, but the moment you resell that stock to a consumer anywhere in the EU, a separate set of rules kicks in — one that has nothing to do with the trade terms you agreed with your supplier. The EU's Sale of Goods Directive gives every consumer a legal guarantee on goods they buy, used phones included, and as the seller of record to that consumer, the obligation lands on you. Understanding what that guarantee actually requires — and how it differs from any warranty your supplier offers you — is essential before you list a single unit for resale.

The EU Legal Guarantee: What It Actually Requires

Directive (EU) 2019/771 sets a default legal guarantee of two years from the date of delivery for any goods sold to a consumer, new or used. Within that period, if a phone doesn't conform to what was agreed — whether that's a functional fault or a mismatch with how it was described — the consumer is entitled to a remedy: repair, replacement, a price reduction, or in some cases a full refund.

• Default period: two years from delivery, EU-wide.
• Applies to: any sale where the seller is a business and the buyer is a consumer (B2C) — not B2B trade between you and your supplier.
• Cannot be waived: the guarantee is a mandatory right and cannot be excluded by a "final sale" or "as-is" clause in a consumer contract.

Where Member States Can Shorten the Period for Used Goods

The Directive allows an important carve-out specifically for second-hand goods: member states may permit sellers and consumers to agree, at the time of sale, on a guarantee period shorter than two years — typically one year — for used items. This isn't automatic. It has to be explicitly agreed and stated in the sales contract, and not every member state allows the reduction at all. Since the rule varies by country, resellers selling into multiple EU markets should check the local transposition of the Directive rather than assuming a one-year term applies everywhere.

The Burden-of-Proof Window

A second mechanism matters as much as the guarantee length itself: the presumption period. If a fault appears within one year of delivery, EU law presumes it already existed at the time of sale, and the burden shifts to the seller to prove otherwise. Some member states extend this presumption to the full two years. In practice this means a consumer doesn't need to prove the phone was already faulty when they bought it — you, as the seller, need to prove it wasn't, if you want to dispute a claim. That's a meaningfully different starting position than most sellers assume.

Your B2B Warranty Is Not the Same Thing

It's worth separating two things that get conflated. The warranty terms you get from a wholesale supplier — a DOA window, a grading-accuracy guarantee, a defective-unit return policy — govern your trade purchase and are commercial terms you negotiate. See our guide on wholesale phone returns and defective units for how that side works. The EU consumer legal guarantee is a completely separate, statutory obligation that attaches the moment you sell to an end consumer, and it exists independently of whatever warranty your own supplier gave you. A short supplier DOA window does not shorten your legal guarantee obligation to your own customer.

Grading, Description Accuracy, and Conformity

The legal guarantee covers "conformity" — whether the phone matches what was agreed and advertised, not just whether it's functionally broken. This is where accurate grading matters commercially, not just cosmetically. A phone sold as Grade B that arrives with Grade D cosmetic wear can be a conformity issue even if it works perfectly. Buying stock with consistent, documented grading — and describing it accurately in your own listings — reduces the number of conformity disputes you'll face, separate from genuine functional faults covered by the guarantee itself.

Practical Steps for Resellers

• Keep a condition record at the point of sale — grade, IMEI, battery health, and any listing description — to support your position if a fault is disputed within the one-year presumption window.
• State the guarantee terms clearly at checkout, including whether you're applying the standard two-year term or a shorter agreed period where your market allows it.
• Don't rely on "as-is" language to exclude the legal guarantee in any B2C sale — it isn't enforceable against a consumer in the EU.
• Track your own compliance requirements separately from your supplier relationship — your legal guarantee obligation to consumers exists regardless of what warranty period your supplier offers you as a wholesale buyer.

FAQ

How long is the legal guarantee on a used phone sold to an EU consumer?

Under the EU's Sale of Goods Directive (2019/771), the default legal guarantee period is two years from delivery. For second-hand goods specifically, member states are allowed to let sellers and consumers agree to a shorter period — commonly one year — but this must be explicitly agreed at the point of sale, not assumed. Some member states don't permit any reduction at all, so the applicable minimum depends on where your buyer is based.

Is this the same as the warranty I get from my wholesale supplier?

No. Your supplier's B2B warranty covers the trade transaction between you and the supplier — typically a shorter DOA or grading-accuracy window. The EU consumer legal guarantee is a separate obligation that attaches automatically when you, as the seller, sell a used phone to an end consumer in the EU. You owe the consumer the legal guarantee regardless of what warranty terms your own supplier gave you.

Who has to prove the fault existed at the time of sale?

Under Directive 2019/771, a defect that appears within one year of delivery is presumed to have existed at the time of sale, and the burden is on the seller to prove otherwise. Some member states extend this presumption period to the full two years. In practice, this means resellers should keep clear condition and testing records at the point of sale, since disputing a claim without documentation is difficult.

Does grading a phone as Grade B or C reduce my legal guarantee exposure?

Grading does not remove the legal guarantee, but it does set consumer expectations about cosmetic condition, which matters for claims based on "conformity" with what was advertised. A properly graded and accurately described phone that later develops an unrelated fault is still covered by the guarantee — grading protects you against cosmetic disputes, not against the guarantee itself.

Can I sell used phones as final sale with no returns to EU consumers?

No. The legal guarantee is a mandatory consumer right in B2C sales across the EU and cannot be waived or contracted away, even with a "final sale" or "as-is" clause. Any such clause is generally unenforceable against a consumer. This only applies to consumer sales — as a wholesale buyer purchasing from SmartChoice, your own transaction with us is B2B and governed by our separate trade terms.
