Refund policy

Last Updated: October 23, 2026

Nakkaa accepts eligible return and exchange requests within 30 calendar days after delivery. Contact service@nakkaa.shop before sending an item back. We do not charge restocking fees, return authorization fees, or exchange handling fees.

1. Customer-Requested Returns

You may request a return if you change your mind, order the wrong part, or select an incompatible component when our product information was accurate. The item must be unused, unmodified, and in its original condition, with all parts supplied in the order.

Opening the package for reasonable visual inspection is allowed. You may compare mounting points, dimensions, cable ends, or electrical connectors without operating the item. For a change-of-mind return, a part must not have been filled with fuel, run on an engine, cut, rewired, or damaged during installation.

Return complete kits, including supplied gaskets, O-rings, filters, clamps, cables, and other accessories. Keep the original product packaging where practical and use protective shipping packaging. Damage to an outer shipping carton alone does not make an otherwise eligible return ineligible.

2. Product Problems and Our Responsibility

Contact us if an item is defective, damaged in transit, incorrect, incomplete, or materially different from its description. Include your order number and a description of the issue. Photos or a short video can help, but contact us even if these are unavailable.

If a part does not fit because our description or our written compatibility advice was inaccurate, we treat the issue as our responsibility. We will review the information and arrange an appropriate replacement, missing component, or refund. Any alternative repair or partial refund requires your agreement.

A genuine defect discovered during correct installation or use is not automatically excluded by the unused-condition rule. Stop using a suspected defective part and contact us. We may waive a return when it is unnecessary or unsafe.

3. Return and Exchange Shipping Costs

• Approved customer-requested returns and exchanges: we provide a prepaid return label at no charge.
• Defective, damaged, incorrect, incomplete, or misdescribed items: we provide a prepaid return label at no charge when a return is required.
• Approved replacement shipments within our supported U.S. delivery area: standard shipping is free.
• There is no restocking or exchange handling fee, and we do not deduct the prepaid return-label cost from an approved refund.

Use the label and return method supplied by our team. If you prefer another carrier or want to purchase your own postage, obtain our agreement first; postage purchased independently is not automatically reimbursed.

4. Items Not Eligible for a Change-of-Mind Return

• Parts used or operated beyond the reasonable inspection described above.
• Parts filled with fuel, contaminated, altered, cut, rewired, or damaged by the customer.
• Damage caused by forced installation, incompatible wiring, improper adjustment, or use contrary to the equipment's instructions.
• Incomplete kits or items missing components that the customer lost after delivery.
• Items that cannot be identified as purchased from Nakkaa.
• Requests made more than 30 calendar days after delivery, unless another remedy or longer period is required by applicable law.

Discounted items follow the same eligibility rules as full-price items. These exclusions do not remove rights concerning defects, inaccurate descriptions, incorrect goods, or any other rights that cannot lawfully be excluded.

5. Return Process

1. Email service@nakkaa.shop within 30 calendar days after delivery. Include the order number, item, reason for the request, and whether you prefer a refund or exchange.
2. We aim to respond within 2 business days. Once approved, we email the designated return address, prepaid label, and packing instructions. The company business address is not the designated return address.
3. Send the return within 14 calendar days after approval, unless we agree to an extension. Include all supplied components and keep the tracking record or carrier receipt.
4. We inspect the return within 3 business days after receipt and email the result. If there is an eligibility concern, we explain the reason and discuss the available options with you.

A request made within the 30-day period remains timely even if our reply or the approved return transit occurs afterward. If you have already sent an item without authorization, email us so we can help locate it.

Do not send a part containing fuel or another spillable liquid. Tell us if a component has been exposed to fuel so we can provide suitable handling instructions or discuss another way to assess the claim.

6. Refund Amount

For an approved return, we refund the price paid for the returned item after allocated discounts, together with its applicable sales tax.

• Customer-requested return: an original $3.99 shipping charge, if paid, is not refundable. We do not retroactively charge shipping on an order that originally qualified for free shipping, including when a partial return reduces the retained merchandise below $20.00.
• Our responsibility: if the entire order is returned because of a confirmed product issue or our error, we also refund the original shipping charge. For a partial affected order, we refund an appropriate share of that charge.

7. Refund Timing

After the returned item passes inspection and the refund is approved, the refund will be received in your original payment method within 7 business days. We send a confirmation when the refund is issued. If the refund is not visible within that period, contact service@nakkaa.shop so we can trace it with the payment provider.

If we approve a refund without requiring a return, the same 7-business-day receipt period begins on the approval date. We do not substitute store credit unless you choose it.

8. Exchanges

Request an exchange within 30 calendar days after delivery and follow the same approval, return, and inspection process. Customer-selected exchanges must meet the change-of-mind conditions. Exchanges for a defect or our error follow the product-issue rules.

After inspection and approval, an available replacement is prepared within 1-3 business days and normally takes another 3-7 business days in transit. Replacement standard shipping is free within our supported U.S. area. If you choose a differently priced item, we explain the price difference and obtain your agreement before collecting or refunding the balance. If a suitable replacement is unavailable, you may choose another available item or a refund.

9. Cancellations

Email us promptly if you want to cancel. If the order has not been dispatched, we will cancel and refund the paid item price, applicable tax, and any shipping charge for the canceled order. The refund will reach the original payment method within 7 business days after cancellation confirmation. If the order has already been dispatched, follow the return process after delivery.
