Chargeback for Item Not as Described: What Merchants Need to Know

What is an "item not as described" chargeback?

An "item not as described" chargeback — also called "not as described or defective merchandise" — is filed when a cardholder claims the product or service they received was materially different from what was advertised. This is different from "not received" (where nothing arrived) — here, the customer received something, but disputes its accuracy.

Common scenarios include: product dimensions or specifications that didn't match the listing, digital products that were different from the description, services that weren't rendered as agreed, items in significantly worse condition than described, and counterfeit or incorrect products.

The merchant's challenge in these disputes is proof. The cardholder is claiming a subjective mismatch — "this isn't what I ordered" — and you must demonstrate with evidence that what they received matched your accurate description. This is harder than proving delivery, but winnable with the right documentation.

Reason codes for "not as described" chargebacks

The specific reason codes vary by card network:

• →Visa 13.3 — Not as Described or Defective Merchandise/Services: applies when a cardholder claims the goods or services received were materially different from what was described at the time of sale, or were defective
• →Mastercard 4853 — Goods or Services Not as Described or Not Provided: Mastercard uses code 4853 for both "not as described" and "not received" disputes
• →Amex C31 — Goods/Services Not as Described: American Express's equivalent for not as described claims
• →Amex C32 — Goods/Services Damaged or Defective: Amex separates defective merchandise from general "not as described"
• →Discover RM — Return: Discover uses this code for disputes where the cardholder claims the item was materially different

Each network has different evidence requirements, though the core evidence types are consistent. Response deadlines: Visa 30 days, Mastercard 45 days, Amex 20 days.

Evidence needed to fight a "not as described" chargeback

The most important evidence for this dispute type is proof that your listing accurately described what the customer received:

• →Screenshots or archived copies of the product listing at the time of sale — including all specifications, dimensions, materials, and terms
• →Photos of the item as shipped, if you photograph outgoing inventory
• →Proof of successful delivery (tracking + delivery confirmation) — establishes the customer received the item before you can discuss its condition
• →Customer communication: any messages where the customer describes the issue — their own words often provide the clearest picture of whether the dispute is legitimate
• →Third-party verification: for professional services, completed work records or sign-off documentation
• →Return policy: if the customer had a straightforward avenue to return the item and did not use it, this weakens their chargeback claim

What does not help: general photos of the product that weren't specific to the customer's order, or verbal claims about the listing without screenshots to back them up. The card network needs documentary evidence, not assertions.

How to prevent "not as described" chargebacks

Most "not as described" disputes stem from a genuine gap between customer expectation and what they received — even when the listing was technically accurate. Prevention requires closing that gap:

• →Use multiple high-quality photos from multiple angles — customers who can see exactly what they're getting have fewer surprises
• →Include accurate dimensions, materials, and specifications — especially for products where size or quality expectations vary widely
• →Be explicit about what's not included — if you're selling an item without accessories, say so clearly
• →Use "as-is" or condition disclosure language for secondhand items
• →Archive your product listings: if a customer disputes months later, you'll need to prove what the listing said at the time of sale
• →Send detailed order confirmation emails that summarise what was purchased — a customer who received an email confirmation with the full specification has a harder time claiming they expected something different

The most effective long-term prevention is investing in listing quality. Accurate descriptions reduce chargebacks, reduce customer service load, and improve conversion — it's a rare case where doing the right thing for SEO is also the right thing for dispute management.

When you should accept the chargeback

Not every "not as described" chargeback is worth fighting. There are specific situations where accepting the dispute is the better business decision:

• →Your listing was inaccurate or misleading — if the customer has a legitimate point, fighting the dispute wastes time and still counts against your ratio whether you win or lose
• →The evidence is weak — if you don't have screenshots of the listing at the time of sale, or clear photos of what was shipped, your chances of winning are low
• →The transaction value is low — for small-value disputes, the time cost of building a rebuttal often exceeds the transaction value
• →You'd rather refund proactively — refunding a complaint before it becomes a chargeback avoids the fee, avoids the ratio impact, and avoids the time cost

A refund doesn't hurt your chargeback ratio. A chargeback — even one you win — does count against it. When the customer has a legitimate concern and the transaction value doesn't justify fighting, issuing a refund and asking the customer to withdraw the dispute is often the right outcome.
