Used Phones

DOA, Warranty, and Returns on Wholesale Phone Lots

How to write dead-on-arrival, seller warranty, and return shipping terms before a used or unused phone lot ships.

Direct answer

DOA is a commercial claim that a unit failed on arrival under an agreed test, inside an agreed window, with an agreed shipping party. It is not a consumer law by itself and not a refurbished warranty. Write the percentage, the clock, the test, and who pays the lithium return before the lot leaves.

Key takeaways

  • A chat promise of “easy returns” is not a DOA clause.
  • Time starts from a named event such as delivery, open, or first power-on.
  • The fail test must match the QC checklist you used to buy.
  • Return freight on phones is a lithium shipment, not a letter in a bag.
  • Seller warranty and manufacturer warranty are different documents.

DOA is where a cheap quote becomes an expensive carton. Write it before the phones move.

What the risk means

Dead on arrival should mean: a named unit failed a named test, inside a named window, after a named delivery event, and the seller will credit, replace, or refund under a named process.

It is not:

  • A consumer cooling-off right
  • Proof the lot was refurbished
  • The same thing as Apple Certified Refurbished, which Apple describes as its own process and limited warranty
  • Automatic under the Incoterm you used to ship the first leg

The U.S. International Trade Administration notes that Incoterms describe obligations for delivery, risk, and cost on the contracted movement. They do not replace a claims clause.

Why bulk buyers should care

Phones fail in the first week more often than in the brochure. If the return window is “tell us soon” and the freight is on you, you will eat locked, dead, and wrong-version units.

Return cargo with lithium-ion cells is still a dangerous-goods movement. IATA publishes lithium battery transport rules, including UN 3481 for equipment packed with or contained in equipment. A WhatsApp “send them back” is not a shipping plan.

Accept / Clarify / Reject

Term Accept Clarify Reject
Window Hours or days from delivery, written “Reasonable time” No window
Test Same QC list as the buy “Doesn’t work” Seller’s secret retest only
Remedy Credit, replace, or refund named “We will see” No remedy
Freight Who books and who pays “Share later” Buyer pays all, including seller error
Cap % or unit count written Silent cap after arrival Hidden 0% after you paid

How to write the clause

  1. Name the start event: carrier delivery scan, warehouse open, or first power-on.
  2. Name the tests that count as DOA. Point at your bulk QC checklist. Locks and IMEI flags belong here if they were Accept conditions.
  3. Name photos and IMEI evidence you will send.
  4. Name the remedy and the cap.
  5. Name who arranges the lithium return and under which packing instruction.

Seller warranty versus manufacturer warranty

A 30-day seller warranty is a commercial promise from the person you paid. A manufacturer warranty is a brand program that may be void outside a region, after a lock, or after a third-party part. Do not assume one covers the other.

Refurbished lots need both the process and the warranty. See refurbished phones.

Common supplier wording

  • “Easy DOA, we are partners”
  • “No returns on Grade C”
  • “Warranty starts when we ship, not when you receive”

Frequently asked questions

Is 3% DOA a standard?

No. Percentages are negotiated. A low DOA with a narrow test is not kinder than a higher DOA with a clear test. Write both.

Does Incoterms decide who pays a DOA return?

Incoterms 2020 allocate cost and risk for the original movement of goods. They do not automatically write your after-arrival claim. Put the return party in the order.
