Returns Policy
Last Updated: September 24, 2026
NCNR
Concentric Silicon, Inc. (“Concentric Silicon,” “we,” “us,” or “our”) sells electronic components and related products (“Products”) to commercial buyers.
Except as otherwise agreed to in writing, all sales of conforming Products are final, non-cancelable, and non-returnable (“NCNR”).
We do not accept returns, cancellations, refunds, exchanges, or credits due to ordering errors, excess quantities, changes in demand, program or design changes, obsolescence, changes in market price or availability, or because a Product is no longer required.
Inspection & Claims
Buyer is responsible for inspecting Products promptly upon receipt.
Any shortage, incorrect quantity, shipping discrepancy, visible damage, documentation or traceability issue, or other concern reasonably identifiable during incoming inspection must be reported in writing to contact@concentricsilicon.com within ten (10) business days of delivery.
Claims should include the order or invoice number, manufacturer part number, affected quantity, lot or date code where applicable, a description of the issue, and photographs or other supporting information where available.
Issues that could not reasonably have been identified during normal incoming inspection, such as authenticity concerns, electrical failures, or other latent nonconformities discovered through testing or use, must be reported in writing promptly after discovery and no later than thirty (30) calendar days from delivery.
Failure to report an issue within the applicable period will constitute acceptance of the Products with respect to that issue.
Return Authorization
No Product may be returned without a written Return Material Authorization (“RMA”) issued by Concentric Silicon.
Issuance of an RMA does not mean that a claim has been accepted or guarantee a replacement, credit, or refund.
Products returned without authorization may be refused or returned to Buyer at Buyer’s expense.
Buyer must preserve and return the affected Products, packaging, labels, and documentation.
Evaluation & Remedies
Concentric Silicon may inspect the Product and review available documentation, testing, manufacturer information, or independent laboratory findings when evaluating a claim.
Claims may be denied where an issue was caused or contributed to by improper handling, storage, installation, soldering, rework, programming, ESD, contamination, misuse, alteration, or use outside the manufacturer’s specifications.
If Concentric Silicon confirms that a Product did not conform at the time of delivery, Buyer’s sole and exclusive remedy, at Concentric Silicon’s option, will be:
- replacement of the affected Product, subject to availability;
- credit for the affected Product; or
- refund of the amount paid for the affected Product.
Any remedy applies only to the quantity confirmed to be affected.
Unless otherwise agreed in writing, Concentric Silicon is not responsible for shipping, freight, duties, taxes, insurance, installation, removal, assembly, rework, programming, testing, production downtime, or other costs incurred by Buyer in connection with a claim.
Unless otherwise agreed in writing, any third-party testing costs associated with a claim are the responsibility of Buyer.
Special NCNR / Hold Harmless Transactions
Certain transactions may be subject to separate NCNR, Hold Harmless, or other transaction-specific terms.
Where Buyer agrees to separate written terms, those terms apply in addition to this Policy and will control in the event of a conflict.
Warranty & Liability
Concentric Silicon is a distributor and does not manufacture the Products we sell.
Except as expressly stated in writing for a specific transaction, Concentric Silicon does not provide any additional warranties or representations regarding the Products.
To the fullest extent permitted by law, Concentric Silicon disclaims all implied warranties, including merchantability and fitness for a particular purpose.
Concentric Silicon is not responsible for any indirect, incidental, special, or consequential damage arising from the purchase or use of a Product, including loss of profits, revenue, production, use, or business opportunity.
Concentric Silicon’s total liability arising out of or relating to any Product will not exceed the amount actually paid to Concentric Silicon for the affected Product.
Counterfeit Avoidance & Traceability
To protect the integrity of the electronic component supply chain and guard against counterfeit or nonconforming parts, Concentric Silicon will not accept the return of any Product where the identity of the Product or its chain of custody cannot be reasonably verified to our satisfaction.
We reserve the right to refuse any return and to quarantine any Product while the matter is investigated, or report it to the manufacturer or applicable authorities, where we reasonably suspect the Product has been altered, substituted, tampered with, or otherwise compromised after delivery.
How to Request a Return
To request consideration of a return, contact our team in writing within the applicable timeframe described above with your order or invoice number, manufacturer part number, affected quantity, lot/date codes, and a detailed description and photographs of the alleged defect.
Do not ship any Product back to us before receiving a written RMA.
