30-Day Limited Warranty

Warranty Period

NINTE offers a 30-day limited warranty beginning on the delivery date shown in the carrier's tracking record. This warranty period is separate from shipping estimates and the reporting period for damage present upon arrival.

What Is Covered?

This limited warranty covers manufacturing defects and product malfunctions caused by a product defect during the warranty period. Please provide supporting information so we can assess the reported issue.

What Is Not Covered?

Damage caused by improper installation, accidents, misuse, or normal wear and tear is not covered as a manufacturing defect. Installation alone does not eliminate rights relating to an existing product defect.

How Do I Submit a Warranty Claim?

For an issue discovered during the 30-day warranty period, contact info@ninteshop.com within 72 hours of discovering the issue.

• Provide your order number or other proof of purchase.
• Describe the problem and when you first noticed it.
• Include clear photographs showing the product and the reported issue.
• For a fitment concern, include the product link, vehicle year, make, model, trim, and relevant photographs.

Keep the product while we review your request. Do not return, discard, or destroy it without written instructions from NINTE.

What Happens After Review?

After assessing the issue, we will explain the appropriate replacement, authorized return, or refund arrangements under our Return, Refund & Cancellation Policy and applicable customer rights.

For a confirmed NINTE-caused issue, the appropriate return, replacement, or refund will be arranged at our expense. Customer-related restocking fees do not apply to a confirmed NINTE-caused return.

What If My Product Arrives Damaged?

Damage present upon arrival should be reported within 72 hours (3 days) of delivery. Include your order number and photographs of the damage, product, packaging, and shipping labels. Keep the product and packaging while we review the claim.

This delivery-damage reporting period starts at delivery. The warranty notification period described above starts when you discover the issue. They are different reporting requirements.

Your Consumer Rights

This limited warranty does not exclude or restrict implied warranties or other rights that cannot lawfully be excluded. Applicable consumer rights take priority over any conflicting reporting deadline, exclusion, or store-policy provision. Your rights may vary depending on applicable state law.

Frequently Asked Questions

How long does shipping take, and where will my order ship from?

For orders delivered to U.S. addresses, processing takes 0-1 business days after payment confirmation. After dispatch, estimated transit time is 3-12 business days from a U.S. warehouse or 10-20 business days from China.

We ship from a U.S. warehouse with available stock. If an item is unavailable at all U.S. warehouses, it ships from China. Free shipping does not necessarily mean an item ships from a U.S. warehouse.

Business days exclude weekends and public holidays. Processing ends when the order is handed over to the carrier, and transit begins after dispatch. Estimated total delivery time is processing plus transit time. These are estimates, not guaranteed delivery dates. See our Shipping Policy for details.

Do you offer free shipping?

Most items qualify for free shipping. Product and destination restrictions may apply, and applicable shipping charges are displayed at checkout before payment. For special destinations, please contact us before ordering to confirm availability and charges.

Can you ship to a P.O. Box?

Most products require a physical street address and cannot be shipped to a P.O. Box. If you need P.O. Box delivery, contact info@ninteshop.com before ordering so we can confirm availability and any additional charges for the specific item and destination.

How can I check whether a part fits my vehicle?

Check the product page for the supported vehicle years, make, model, trim, body style, bumper configuration and any stated exclusions. Do not assume a part fits every trim or model year.

If you are unsure, email info@ninteshop.com with the product link, vehicle details and relevant photos before ordering. Inspect and test-fit the product before permanent installation, painting, drilling, cutting or modification where practical.

What should I do if my item arrives damaged, incorrect or defective?

For damage present upon arrival, email info@ninteshop.com within 72 hours (3 days) of delivery. Include your order number, a description of the problem, and photos of the product, packaging and shipping labels. Keep the item and packaging while we review your request.

For an incorrect item, contact us within 30 days of delivery. Report other product defects promptly so we can assess the issue under the applicable return or warranty provisions. The 72-hour delivery-damage reporting period does not replace applicable warranty or statutory rights.

After confirming the issue, we will explain the appropriate replacement, return or refund arrangements. Customer-related restocking fees do not apply to a confirmed NINTE-caused return.

What is your return policy?

Non-defective returns are accepted only for orders originally delivered to the United States, Canada, or the United Kingdom, subject to our return policy. For other delivery countries, non-defective returns are not accepted except where required by applicable law.

For an eligible non-defective return, contact us within 30 days of delivery to request authorization. Items must be unused, in their original packaging and in their original condition, with included components.

Do not send an item back before receiving authorization and instructions for our designated U.S. return warehouse. Do not use the address on the original package unless we confirm it as your return address. Different arrangements apply to damaged, defective, incorrect or misdescribed products. The country restriction does not limit statutory consumer rights.

Are there any return fees?

For an eligible customer-related, non-defective return, a restocking fee of 20% of the original purchase price of the returned merchandise applies where permitted by applicable law. The customer is responsible for return shipping costs.

If merchandise is damaged during a customer-arranged return shipment, a deduction of 50% of the original purchase price of the affected merchandise may apply where permitted by applicable law, with supporting photographs provided by NINTE. This replaces, rather than adds to, the 20% restocking fee for the same merchandise.

Return deductions are separate from the pre-fulfillment cancellation process. Review our Return, Refund & Cancellation Policy for full conditions and exceptions.

Can I cancel my order?

Contact info@ninteshop.com as soon as possible. Sending a cancellation request does not confirm cancellation; we must first confirm whether the order can still be stopped before fulfillment.

For eligible customer-requested cancellations before fulfillment, a fixed cancellation fee of 8% of the amount actually paid for the canceled order applies, and the remaining 92% will be refunded. For partial cancellations, the calculation applies only to the canceled portion. Required tax adjustments are handled under applicable law.

Fraud-risk cancellations follow the same 8% fee calculation only where permitted by applicable law and the relevant payment-provider and card-network rules. Other NINTE-initiated cancellations, including unavailable inventory or inability to fulfill an order, receive a full refund.

The policy applies to all accepted payment methods, subject to the rules governing each transaction. No cancellation fee is deducted where mandatory legal or payment-provider requirements require a full refund or reversal. Where the 8% fee applies, it is deducted once, without additional cancellation-related deductions or restocking fees.

Orders already shipped cannot be canceled through the pre-fulfillment process. Contact us for return instructions rather than refusing delivery without prior instructions. See our Return, Refund & Cancellation Policy for full conditions and exceptions.

Do you offer a warranty?

Yes. We offer a 30-day limited warranty. Please review the Warranty tab for coverage, exclusions and claim requirements. Contact info@ninteshop.com with your order number, photos and a description of the issue.

Damage caused by improper installation, accidents or normal wear and tear is not treated as a manufacturing defect. Delivery damage should be reported within 72 hours of delivery as explained above. Nothing in this FAQ limits rights that cannot lawfully be excluded.

How do I track my order?

You will receive tracking information by email once your order ships. If you have not received it or need help with a shipment, email info@ninteshop.com with your order number.

Do you accept orders outside the United States?

Availability depends on the product and destination. Contact info@ninteshop.com before ordering to confirm shipping availability, charges and delivery estimates. The U.S.-destination delivery estimates above do not apply to other countries. Please review our Shipping Policy for restrictions.

Will I pay sales tax or additional import fees?

Prices are in U.S. dollars. Applicable sales taxes depend on the delivery address and applicable tax rules. Any sales taxes collected at checkout are displayed before payment.

Under our current Shipping Policy, customers will not be charged additional import duties, import taxes or customs clearance fees. Applicable shipping charges are separate and are displayed at checkout.

How do I contact customer support?

Email info@ninteshop.com or visit our Customer Support Center. For an existing order, include your order number and relevant details. For a fitment question, include the product link and vehicle information.
