If a product arrives damaged, fails during ordinary use, or differs materially from its listing, contact the seller in writing first. Ask for one specific remedy: a refund, repair, or replacement.

U.S. law does not give consumers a blanket 30-day right to return every defective product. The answer can depend on the seller's policy, a written warranty, state law, payment method, or marketplace guarantee.

Keep the item and its records. Deadlines and available remedies vary by route. This is general U.S. consumer information, not legal advice.

Identify the claim before choosing a remedy

Name the problem before choosing the process. A crushed delivery, a failed product under warranty, and a credit-card billing error may follow different rules and clocks.

Turns out, a store's 30-day or 90-day policy usually covers ordinary returns. It is not a universal federal deadline for a defective product.

The FTC's consumer guidance on resolving business problems recommends explaining the problem, naming the remedy you want, and keeping notes about your efforts.

Save the return policy anyway. It may shape the dispute without deciding the whole thing.

Build the evidence file first

Build a file that answers five basic questions: what you bought, what the seller promised, what failed, when you reported it, and what you requested. Start with these records.

Save the listing before it changes. Save the chat before it closes. Note the dates.

To be honest, an independent repair estimate can help with an expensive or technical item, especially when the diagnosis is disputed, but a minor dispute may not justify paying for one.

Don't discard the packaging, accessories, or serial-number label yet. A seller, warrantor, or card issuer may ask for them.

Follow this dispute workflow

This order keeps safety, proof, and deadlines in view.

1. Make the item safe. Stop using it if it sparks, overheats, leaks, breaks apart, or creates another obvious hazard. Don't modify or dismantle it before the seller or warrantor gives instructions.

2. Pull together the paperwork. Find the order date, seller's name, return terms, warranty period, model or serial number, and payment method. Save the product page and any promised delivery or performance details.

3. Record what happened. Photograph the product, packaging, labels, and visible damage. If it is safe, take a short video showing the problem. Write down when the failure occurred and what you were doing then.

4. Contact the seller in writing. Describe the purchase and defect briefly. Request a refund to the original payment method, a replacement, or a repair. Ask how to return the item and who will pay the return shipping.

5. Use the return instructions exactly. Save your submission and photograph the packed item. Use tracking if you send it back, and keep your records rather than putting the only copy in the box.

6. Escalate on paper. If the seller refuses or stops responding, contact the manufacturer or warranty administrator and open the marketplace process, if one is available. The FTC guidance linked above includes a sample complaint letter and recommends saving copies of online forms and chats.

7. Track every deadline separately. A warranty, marketplace claim, and credit-card billing dispute may each have its own clock. Keep negotiating only if you can do so without losing another option.

Choose between a refund, repair, and replacement

Choose based on the defect and whether you still want the item. A seller's policy or warranty may control the first offer, while state law may provide additional rights.

A first offer is not necessarily the final outcome. Whether you can insist on a refund often depends on the warranty language, state law, seriousness of the defect, and whether the seller gets a reasonable chance to fix the problem.

Safety comes first. Don't keep using a dangerous product just to create more proof.

Read the warranty instead of relying on the label

Read the warranty itself. A box that says "warranty" does not tell you all the terms.

Look for the duration, covered parts, exclusions, claim steps, shipping instructions, and limits on damages. Those details matter.

Under the Magnuson-Moss Warranty Act, the FTC says its disclosure and pre-sale availability requirements apply to written warranties on consumer products costing more than $15. Such warranties must also be identified as either "full" or "limited." The FTC's federal warranty guide describes the requirements for businesses.

The federal warranty interpretations in 16 CFR Part 700 distinguish a time-limited promise about performance from a general product description. The warranty disclosure rules in 16 CFR Part 701 address exclusions and limits on relief, among other terms.

Magnuson-Moss does not turn every product failure into an automatic cash refund. It governs certain written warranties and the remedies those warranties promise. Implied warranties are mainly matters of state law, and "as is" language or other disclaimers may affect them.

An expired written warranty may close one route without ending every possible claim. Check the purchase date, any separate promise from the seller, and the law that applies to the transaction.

Responding to a warranty denial

Get the denial in writing. Ask for the exact warranty clause, inspection finding, or exclusion the company relied on. "Normal wear" alone is not enough detail to evaluate the decision.

Keep the escalation factual:

On [date], I bought [item] from [seller] for [amount]. The item developed this problem: [specific description]. I reported it on [date] and was told [response]. I am requesting [refund, repair, or replacement]. Please provide the next steps and the applicable warranty provision in writing.

Attach the receipt, photos, warranty page, and earlier correspondence. Keep the message focused. A usable record is more helpful than a long argument.

If the manufacturer says the seller must handle the matter, ask the manufacturer to confirm that position in writing. Send that response to the seller. If the warranty includes an informal dispute process, follow it before filing a court claim when the terms require that step.

Credit-card disputes follow a different process

Use the card issuer's billing-error process separately from seller negotiations. A chargeback is not a general federal refund button.

A defective product may fit that process if the goods were not accepted or were not delivered as agreed. A disagreement about warranty service does not automatically qualify, so describe the problem accurately instead of labeling an authorized purchase as fraud.

For a U.S. credit card, send written notice to the billing-inquiries address on the statement. Include your name, account information, disputed amount, transaction date, merchant, and a description of the problem.

The familiar 60-day deadline generally starts with the first statement showing the billing error. It generally does not start when you finally stop negotiating with the seller.

The CFPB's Regulation Z billing-error rule requires the issuer to acknowledge the notice within 30 days unless it resolves the matter sooner. The investigation generally must finish within two complete billing cycles and no later than 90 days.

Continue paying the undisputed portion of the account. A temporary credit, if the issuer provides one, is not necessarily the final decision.

Debit cards, prepaid cards, buy now, pay later services, wires, and peer-to-peer payments can follow different laws and provider procedures. Don't transfer the credit-card deadline to another payment type.

Marketplace policies have their own clocks

A marketplace guarantee is a company process. It may help produce a refund, but it does not replace a written warranty or every remedy available under state law.

For eBay, the Money Back Guarantee policy sets issue-specific deadlines and conditions. For several report types, it lists a latest reporting date of 30 calendar days after the estimated or actual delivery or collection date. In several situations, the seller has up to three business days to respond.

When eBay decides a dispute, the policy allows an appeal within 30 calendar days of the decision. If a return is required, follow the platform's instructions exactly and keep tracking and delivery proof. Item category, delivery method, condition, and exclusions can change how the policy applies.

Thing is, the marketplace deadline may arrive before you've finished testing the product. Open the platform case promptly, then keep the warranty and payment records moving on their own tracks.

For Amazon or another marketplace, use the order-specific process shown in your account. Save the case number, messages, and return instructions. Policies can vary by seller, item, order, and country, so don't rely on an old general deadline.

Small claims and other escalation routes

Small claims court can make sense when the amount is modest and the evidence is clear. Filing limits, fees, service rules, hearing locations, and recoverable costs vary by state and county, so use the court's official instructions rather than assuming one national dollar limit.

Before filing, send a final demand. Give a short timeline and state the exact amount you want. Include the purchase record, defect evidence, warranty or listing promise, communications, and proof that you gave the seller a chance to respond.

Check the purchase terms for an arbitration clause or a required dispute procedure. Those terms may affect where and how you can proceed.

A complaint to a government or consumer agency can create a record or reveal a broader pattern. It is not a guaranteed individual refund. If the defect caused an injury or substantial property damage, preserve the product and seek case-specific legal help instead of treating it as an ordinary return.

Mistakes that weaken a defective-item claim

These choices can make an otherwise solid record harder to use:

• Relying on a phone call without recording the date, representative's name, and result.
• Letting weeks of negotiation pass while a credit-card or marketplace deadline gets closer.
• Returning the item without tracking or without photographing its condition first.
• Calling an approved purchase unauthorized fraud because you have a quality dispute.
• Accepting store credit before confirming that it solves the problem.
• Throwing away the product, packaging, serial label, or repair records.

Put every relevant deadline on one calendar today. Create one folder for the receipt, listing, warranty, photos, messages, and tracking number. Then send the written request that names the remedy you want.
