Warranty & Returns

The standard terms we quote and invoice against. The proforma invoice (PI) for your order states the terms that apply to it; where the two differ, the PI controls.

At a glance

Six terms, in the words used on the PI.

Term Standard position
Warranty period 12 months from the date of the bill of lading / air waybill.
Remedy Limited to replacement of the defective part or refund of its invoice value.
Receiving claims Raised within 7 days after receipt of the goods, with a supporting inspection report and photographs.
Losses Consequential and indirect losses are excluded.
Cancellation and change of mind Stated per line on the quotation. A line marked NCNR (non-cancellable, non-returnable) cannot be cancelled or returned once your payment has cleared and the supplier order is placed.
Who gives the warranty Shenzhen Yuanxutong Technology Co., Ltd., to the buyer named on the PI. It is not a manufacturer's warranty.

What the warranty covers

  • A part that is not what the PI describes: a different manufacturer part number, marking, package or quantity
  • A part that does not meet the manufacturer's published datasheet specification for that exact part number when used within that specification
  • A part described on the quotation as new and original that a laboratory report shows is not

What it does not cover

  • Damage from handling, electrostatic discharge, moisture exposure after the barrier bag is opened, or storage outside the manufacturer's conditions after delivery
  • Failures caused by assembly, rework, programming, or use outside the datasheet limits
  • Whether the part suits your design or application
  • Consequential and indirect losses, such as line-down costs, rework labour or lost profit

Check the goods on arrival

Check quantity, labels, the complete part number, package form and visible condition when the goods arrive. Shortages, wrong parts, damaged packaging and marking discrepancies must be raised within 7 days after receipt, with a supporting inspection report and photographs. Where you can, photograph the outer carton and the inner packing before opening sealed moisture barrier bags.

How to raise a claim

  1. 1

    Email [email protected] with the PI number, the manufacturer part number and date/lot code, the quantity affected, what you found, photographs, and your inspection or test report.

  2. 2

    We compare the claim with our Shenzhen receiving record for that lot: the Level 1 photographs of labels, marking and date/lot codes taken before the goods left us. We reply with the next step.

  3. 3

    If a laboratory test is needed to settle the claim, the laboratory, test items, sample size and who pays are agreed in writing before testing starts.

  4. 4

    Do not return goods before we issue a return authorization (RMA) number. Returned parts should travel in their original or ESD-safe packaging, with the RMA number on the outer carton. Freight for the return is agreed in the authorization.

  5. 5

    A confirmed claim is settled by replacement of the defective part or refund of its invoice value.

Why the warranty is written this way

MPNBridge is an independent distributor, not a franchised one. This warranty is our own. It does not extend or replace any manufacturer's warranty, and parts bought outside a manufacturer's authorized channel may not carry one.

Our receiving checks are visual and documentary. They are described, with what they cannot prove, on Source & Quality. The warranty is how we stand behind the goods beyond what those checks can show.

Commercial terms for each order—price, payment, Incoterms, delivery and NCNR status—are set out in the quotation and PI. The general website limits are in the Website & RFQ Terms.

Start with the essentials

Ask about warranty terms before you order.

If your application needs a longer warranty, specific test evidence or different claim terms, say so in the RFQ so the quotation can state what is possible.
