Chargeback for Item Not as Described: How Merchants Win These Disputes [2026]

"Not as described" chargebacks are consumer disputes — different from fraud, and harder to defend than unauthorized transaction claims. The bank asks two questions: was there a material difference, and did the merchant try to resolve it? Answer both correctly and you can win. Answer neither and you will lose every time.

What Is an "Item Not As Described" Chargeback?

An "item not as described" chargeback occurs when a cardholder claims the goods or services they received were materially different from what was advertised, arrived defective, or were counterfeit. Unlike fraud chargebacks (where a stolen card is used), not-as-described disputes are consumer disputes — the cardholder did authorize the purchase, but claims the product didn't meet the standard described.

This distinction matters for your defense strategy. Fraud disputes turn on authorization evidence; not-as-described disputes turn on product matching evidence. They require completely different approaches.

Win rate context

Non-fraud chargebacks like not-as-described disputes have a 56.6% median win rate — significantly higher than fraud disputes at 36.5%. This means these disputes are more winnable than most merchants assume, provided you submit the right evidence.

When the bank reviews a not-as-described dispute, it asks two core questions:

1. Was there a material difference?

The item must be significantly different from the description — not just a minor variation. A cosmetic color difference that falls within a stated range is not material. Receiving a used item when "new" was advertised is.

2. Did the merchant try to resolve it first?

If the customer contacted you and you ignored the complaint or refused a reasonable remedy, the bank is more likely to side with the cardholder. If no complaint was raised before the dispute — or you offered resolution and the customer refused — that favors the merchant.

Note that 75% of consumers go directly to their bank without contacting the merchant first. This works in your favor — if there is no prior complaint on record, you can use that absence as evidence that the cardholder never gave you the opportunity to resolve the issue.

Reason Codes and What They Mean

"Item not as described" disputes are filed under different reason codes depending on the card network. Each network has slightly different filing conditions and deadlines:

Network	Code	Name	Cardholder Claim	Merchant Deadline
Visa	13.3	Not As Described or Defective Merchandise/Services	Item significantly different from description, or defective/damaged	30 days
Visa	13.4	Counterfeit Merchandise	Item received is counterfeit or not genuine	30 days
Mastercard	4853	Cardholder Dispute — Item Significantly Not As Described	Item materially different from advertised or goods not as described	45 days
Amex	C31	Goods/Services Not As Described	Item received does not match description or was defective	20 days
Discover	NC	Not as Described	Merchandise or services differed materially from what was purchased	120 days from transaction

Amex's 20-day deadline is the tightest in the industry. If you process Amex transactions, set an immediate alert the day a dispute arrives — do not wait.

What Merchants Must Prove

To win a not-as-described dispute, you must demonstrate at least one of three things:

A. The item matched the description exactly

Use product listing screenshots, specification sheets, photos of the item as shipped, and manufacturer documentation to demonstrate the product met or exceeded what was advertised.

B. The cardholder is exaggerating — the difference is not material

Not every difference is "significant." If the item was within stated size ranges, color variation was noted in the listing, or the difference is cosmetic rather than functional, document this clearly with side-by-side comparisons.

C. The merchant offered to resolve it and the cardholder refused

If you offered a return, exchange, or refund and the customer declined, that is strong evidence. Include the return authorization, your written offer, and the customer's refusal. This shows the dispute was filed in bad faith or was avoidable.

Evidence Hierarchy

Evidence	Strength	Notes
Product listing screenshots (dated)	Very Strong	Proves exactly what was advertised at time of purchase
Customer used product after complaint	Very Strong	Login after complaint date; shows item was functional
Photos of item shipped vs claimed	Strong	Side-by-side comparison showing item matched listing
Manufacturer specs / quality cert	Strong	Validates technical specifications were met
Return authorization offered, refused	Strong	Shows merchant tried to resolve; customer declined
Customer emails prior to dispute	Strong	Absence of complaint = no pre-existing issue claimed

When to Fight vs When to Refund

Not every not-as-described dispute is worth contesting. Use this decision framework to allocate your time where it matters:

Scenario	Decision	Reason
Item genuinely matched the description	Fight	You have a strong case — listing screenshots and photos are your evidence
Customer exaggerating a minor difference	Fight	Minor variations are not "material" differences; document this clearly
High-value order with friendly fraud signals	Fight	Worth the time investment; document all signals (login after dispute, no pre-complaint)
Item had a real, material defect	Refund	You'll lose the chargeback and pay fees on top; refund directly saves money
Complaint is legitimate and provable	Refund	Accept and improve QC; fighting wastes time and hurts your chargeback ratio
Order under $50	Refund	Time cost of fighting exceeds recovery value for low-ticket items

Remember: Every chargeback you lose — even if you choose not to fight it — counts against your chargeback ratio. If you refund proactively before the chargeback is filed, you can sometimes prevent the dispute from being recorded at all. Contact your processor about their pre-dispute resolution programs.

The Material Difference Test

Card networks only allow "item not as described" chargebacks when there is a significant or material difference between what was advertised and what was received. Minor cosmetic variations, slight size differences within stated ranges, and subjective quality assessments do not meet this standard.

Understanding where this line falls is critical to your defense:

Material differences (hard to win)

✗Advertised as "new" — received a used or refurbished item
✗Advertised as "gold" — received silver-plated or gold-toned
✗Stated as 100% wool — received synthetic blend
✗Completely different product shipped by mistake
✗Item listed as working — arrived broken and unusable

Non-material differences (winnable)

✓Color slightly different from photo (screen calibration variation)
✓Minor size variation within stated tolerance range
✓Packaging differs but product is identical
✓Customer "doesn't like" it — subjective preference, not a defect
✓Minor cosmetic scratch that does not affect functionality

In your rebuttal, explicitly argue the materiality point. State clearly: "The difference cited by the cardholder does not constitute a material deviation from the product description, for the following reasons..." Then reference your listing and evidence directly. Reviewers often accept disputes without challenge because merchants do not make this argument.

The Friendly Fraud Problem with SNAD Disputes

SNAD (Significantly Not As Described) disputes are heavily used for first-party fraud — where the customer received exactly what was advertised, but claims otherwise to get the item for free. In 2024, first-party fraud represented 36% of all chargebacks (up from 15% in 2023), and not-as-described reason codes are one of its primary vehicles.

Warning signs that a dispute may be friendly fraud rather than a legitimate complaint:

!High-value orders — higher incentive to dispute than to return
!Customer bought during a promotional sale or clearance event
!No contact with customer service before filing the dispute (75% go directly to the bank)
!Cardholder has a pattern of previous disputes with you or generally
!Carrier confirms delivery, but customer claims the item was wrong
!Customer logged into the account, used the product, or posted about it on social media after the dispute date
!Same customer ordered the same or similar product again shortly after the dispute

How to fight friendly fraud on SNAD disputes: Login timestamps after the claimed dispute date are your most powerful evidence — they show the customer was actively using the product or account after claiming it was wrong. Social media posts, repeat purchase records, and carrier delivery confirmation with address match all strengthen the case.

Prevention Strategies

The best approach to not-as-described chargebacks is preventing them from being filed in the first place. Strong listing practices and clear communication reduce dispute rates significantly:

✓

High-quality product photos from multiple angles

Show the product from every relevant perspective. Include scale references, close-ups of materials, and photos of any variations. This makes "not as described" claims harder to sustain.

✓

Accurate, detailed product descriptions

Specify dimensions, materials, weight, color ranges, and any variations. If color may vary from screen to screen, say so explicitly. Ambiguous listings invite disputes.

✓

Clear returns and refund policy at checkout

Make your policy visible during the purchase flow — not buried in the footer. Customers who know how to return an item are less likely to file a dispute instead.

✓

Email receipts that confirm exactly what was purchased

Include product name, description, and specifications in confirmation emails. This creates a contemporaneous record of the advertised item that is hard to dispute later.

✓

Pre-approval return process before disputes are filed

Encourage customers to contact you before going to their bank. A simple, frictionless return process reduces chargebacks significantly. Consider including a return instruction card in each shipment.

✓

Collect device and IP data at transaction time

For digital goods, capture download and access logs with timestamps and IP addresses. This evidence is impossible to reconstruct after the dispute arrives.

Frequently Asked Questions

What is a "not as described" chargeback?▾

A 'not as described' chargeback is filed when a cardholder received an item or service but claims it was materially different from what was advertised, defective, or counterfeit. Unlike fraud chargebacks, the customer is not denying they made the purchase — they are disputing what was delivered. The main reason codes are Visa 13.3 (Not as Described or Defective Merchandise) and Mastercard 4853 (Cardholder Dispute — Not as Described). The evidence you need focuses on proving the product matched your published listing at the time of purchase.

What evidence wins Visa 13.3?▾

For Visa 13.3 (Not as Described or Defective Merchandise), the most important evidence is: (1) archived product listing screenshots dated to the time of purchase showing exactly what was advertised, (2) photos of the item as shipped compared to the listing, (3) manufacturer specifications or quality documentation proving technical accuracy, and (4) records showing the customer either did not contact you before disputing or refused your offer to return or resolve the issue. If the customer continued using the item after filing the dispute, document that usage — it is strong evidence the claim is exaggerated.

What evidence wins Mastercard 4853?▾

For Mastercard 4853 (Cardholder Dispute — Not as Described), winning evidence includes: (1) product listing archived at time of purchase showing the accurate description, (2) photos of what was actually shipped versus what the customer claims they received, (3) quality certifications or manufacturer specs showing specifications were met, and (4) customer service records showing you offered a remedy (refund, replacement, exchange) and the customer refused or did not respond. Mastercard gives you 45 days to respond — more time than Visa's 30-day window.

How long do I have to respond to a not-as-described chargeback?▾

Response deadlines depend on the card network: Visa gives merchants 30 days, Mastercard gives 45 days, and Amex gives 20 days. Missing the deadline results in automatic loss regardless of how strong your evidence is. Most acquirers require submission 5–10 days before the network deadline, so start gathering evidence immediately when the chargeback notification arrives.

Can I fight a not-as-described chargeback if the item was accurately described?▾

Yes — and this is a very winnable dispute if you have the right evidence. If your product listing accurately described what the customer received, your defence is straightforward: provide the archived listing as it appeared at the time of purchase, show photos of what was shipped, and demonstrate the item matched the description. If the customer never contacted you before filing the dispute, note this — Visa and Mastercard rules require customers to attempt resolution with the merchant first. Also document any post-dispute usage of the item, which undermines the not-as-described claim.
