Return & Refund Policy

1. Scope of this Policy

This Return & Refund Policy explains when and how you can return products bought from Sichuan Yuanxin Supply Chain Technology Co., Ltd. ("Drone Parts Factory", "we", "us"), and how we handle replacements, credits and refunds. It applies to samples, stock orders, OEM/ODM production orders and spare parts ordered through dronepartsfactory.com, by email or through our sales team.

This Policy forms part of our Terms of Service and works together with our Warranty Policy and Shipping Policy. If this Policy and your accepted quotation, proforma invoice ("PI") or signed agreement differ, the quotation, PI or agreement applies to that order.

Our products are sold to business buyers. Nothing in this Policy removes any rights that cannot be excluded under the law that applies to you.

2. Summary

• Report problems quickly. Visible transport damage, shortages and wrong items must be reported within 7 days of delivery.
• Defects are covered by the warranty. We repair, replace, credit or refund products with confirmed manufacturing defects.
• An RMA number is required. Never send goods back without our written return authorisation.
• Some items cannot be returned. This includes custom and branded products, used or modified products, and lithium batteries (unless defective on arrival).
• Non-defective returns need our consent. They are limited to unopened stock items and may carry a restocking fee.
• Refunds are paid to the original paying account once the return or claim is approved.

3. Return situations at a glance

4. Damage, shortages and wrong items on arrival

Inspect on delivery. Please check cartons and contents when they arrive. If a carton is visibly damaged, crushed or wet, note this on the carrier's delivery receipt before signing and take photos.

Report within 7 days. Tell us within 7 days of delivery about any visible damage, missing items or items that do not match your order. Include the order number, photos of the outer cartons and labels, photos of the affected items and the packing list. Goods not reported within 7 days are treated as delivered complete, correct and in good visible condition.

Transport damage. If we arranged transport (for example under CIF, DAP or DDP, or with our courier account), we file the claim with the carrier or insurer and replace or credit the damaged items. If you arranged transport through your own forwarder (for example EXW or FOB), please file the claim with your forwarder or insurer; we will provide the packing details and documents you need.

Shortages. We check the shortage against our packing records and carton weights. Confirmed shortages are shipped with your next order, sent separately, or credited, whichever you prefer.

Wrong items. If we shipped the wrong SKU or the wrong configuration (for example radio band, connector type, KV rating or colour), we will send the correct item and pay the shipping both ways. We may ask you to return the wrong item or, for low-value items, to keep or dispose of it.

5. Defective products

Products with manufacturing defects are handled under our Warranty Policy. In short:

Dead on arrival (DOA). A product that does not work when first installed and used correctly, and is reported within 7 days of delivery, is treated as DOA. After we confirm the fault, we replace or refund it and pay the return shipping.

Defects found during use. Report defects within the warranty period stated in your quotation or PI (12 months from delivery if none is stated) and within 30 days of discovering the defect. We repair, replace, credit or refund confirmed defective products. We pay to ship repaired or replacement products to you; the buyer pays to send defective products to us unless we agree otherwise.

Before you return. Many reported faults are caused by settings rather than hardware, for example a mismatched ExpressLRS binding phrase or firmware version, a wrong regulatory domain, a UART or protocol setting on the flight controller, or ESC and motor direction settings. Please check our Troubleshooting guide or contact Technical Support first. We can often solve the problem remotely, which saves you time and shipping costs.

What the warranty does not cover. Crash, impact, water or fire damage; wrong wiring, reverse polarity or over-voltage; modification, unauthorised repair or unapproved firmware; wear parts such as propellers, shells, straps and connectors; misused or incorrectly stored batteries; and normal wear. Returns for these reasons are not accepted as warranty claims, but we can quote for repair or replacement parts.

6. Items that cannot be returned

The following items cannot be returned for credit or refund, except where they are defective or were shipped incorrectly by us:

• Custom Products, including items with your logo, labels, packaging, firmware settings, colours or design changes (OEM/ODM).
• Products made or configured to order, such as receivers flashed with a specific regulatory domain or binding phrase at your request, or combo kits built to your bill of materials.
• Used, installed, soldered or modified products, including products with cut wires, removed heat-shrink or changed connectors.
• Lithium batteries, unless defective on arrival, because returned batteries cannot be resold safely and must be shipped as dangerous goods.
• Consumables and wear parts once opened, such as propellers, straps, shells and LED strips.
• Clearance items and products sold as "final sale" in the quotation.
• Software, firmware and digital documents.

7. Returns of non-defective products

We do not normally accept returns of products that are not defective. If you ordered the wrong item or no longer need it, contact us and we will consider a return on these conditions:

• The item is a standard catalog stock item, not a Custom Product.
• The request is made within 14 days of delivery.
• The item is unused and in its original, unopened and undamaged packaging, with all accessories and documents.
• You receive our written approval and RMA number before shipping.
• You pay the shipping costs to us, and the original shipping cost is not refunded.
• A restocking fee of up to 15% of the item price may be deducted to cover inspection, repacking and handling.

Instead of a refund, we can often exchange the item for a different configuration or credit its value against your next order, which usually avoids the restocking fee. Ask your sales contact which option works best.

8. Order cancellations and deposits

Stock orders. You can cancel a standard stock order before it is shipped. We refund the amount paid less any costs already incurred, such as bank charges, special packing or third-party fees.

Custom and production orders. Deposits for Custom Products pay for materials, printing, tooling and production slots. Once these have been ordered, the deposit is non-refundable. If you cancel a custom order, you pay for work already done and for materials bought for your order that cannot be used for other orders. We will show you the costs before settling the cancellation.

Orders we cannot fulfil. If we cancel an order because we cannot supply it, including for export-control or end-use reasons, we refund all amounts paid for the undelivered goods, less costs already incurred for Custom Products where the cancellation is caused by the buyer's information or conduct.

Delays. Where a dispatch is delayed by us by more than 30 days beyond the confirmed date, you may cancel the delayed part of the order and receive a refund of the amount paid for it, as set out in our Terms of Service.

9. Samples

Samples are charged at the sample price plus shipping, as set out in our Sample Order Policy. Samples are used for evaluation and are not returnable or refundable, except when they are defective on arrival or not what we agreed to supply. Where the quotation says so, sample costs are credited against a later bulk order. An approved sample defines the configuration of the related production order, so please report any concern about a sample before approving it.

10. How to request a return (RMA process)

1. 01
   Contact us

   email sales@dronepartsfactory.com or use the After-Sales Service form. Include the order number, SKU, quantity, the problem and, for technical issues, the firmware version and your setup (radio, flight controller, battery).

2. 02
   Send evidence

   photos or a short video that shows the problem. For transport claims, include photos of the cartons and labels.

3. 03
   Diagnosis

   our technical team reviews the information and may suggest troubleshooting steps. Many issues are resolved at this stage.

4. 04
   RMA approval

   if a return is needed, we issue an RMA number, return instructions and the shipping address. If a return is not needed, we may settle the claim directly by replacement or credit.

5. 05
   Ship the return

   pack the goods as described in Section 11 and mark the RMA number on the outside of the carton and on the documents.

6. 06
   Inspection

   we inspect and test the returned goods and tell you the result.

7. 07
   Resolution

   we repair, replace, credit or refund as described in this Policy.

Goods returned without an RMA number may be refused or returned to you at your cost.

11. Packing and shipping returns

• Pack returned goods in the original packaging where possible, or in packaging that protects them as well. Damage caused by poor return packing is not covered.
• Mark the RMA number on each carton and on the invoice or packing list.
• Describe the goods as "returned goods for repair or replacement" with their true value on customs documents. Do not declare them as new goods for sale.
• Buyers outside China should follow the return shipping instructions we send, so that the goods can be re-imported without paying import duty again where possible. Duties and taxes caused by incorrect return documents are paid by the sender.
• Lithium batteries must not be returned without contacting us first. They must be shipped as dangerous goods with the correct packaging and documents. Damaged or swollen batteries must never be shipped by air; we will advise on safe local disposal and settle the claim based on photos.
• Keep the tracking number of your return shipment until the claim is closed.

12. Inspection results and no fault found

We normally inspect returned goods within 10 working days after they arrive. If we confirm the defect or error, we resolve the claim as described in this Policy.

If we find that the product works correctly (no fault found), or that the damage is not covered by the warranty, we tell you the result and the options. You can choose to have the product returned to you at your cost, have it repaired against a quotation, or have it disposed of. If we do not hear from you within 60 days, we may dispose of the product.

13. Refunds and credits

Choice of remedy. For confirmed defects, errors and approved returns, we may repair or replace the product, or credit or refund its price. For distributors, we usually settle small quantities through credit notes or replacement goods in the next order, which avoids extra parcels and bank charges.

What is refunded. Refunds cover the price paid for the affected items. Original shipping costs are refunded only when the whole order was shipped in error or was defective on arrival. Import duties and taxes paid to customs authorities are not refunded by us; you may be able to reclaim them from your customs authority. Restocking fees and bank charges are deducted where this Policy allows.

How refunds are paid. Refunds are paid by bank transfer (T/T) in the currency of the original payment, to the account that made the payment. For fraud-prevention reasons we do not pay refunds to a different person or account. Exchange-rate differences and bank charges on the receiving side are borne by the buyer.

Timing. We process approved refunds within 10 working days after the claim is approved or the returned goods pass inspection. The time for the money to arrive depends on the banks involved.

Credit notes. Credit notes are issued in the order currency and can be applied to any future order. Unless agreed otherwise, they remain valid for 12 months.

14. Distributors and OEM customers

Distributors and OEM customers may agree a different return arrangement in their distribution or supply agreement, such as a defect allowance, batch RMA handling or spare-part stock. In that case the agreement applies. Distributors are responsible for handling returns from their own customers and then submitting consolidated claims to us with the evidence described in Section 10.

For branded products, we accept returns for confirmed manufacturing defects in the same way as for our standard products. Returns cannot be accepted because of your own artwork, text or specification errors once these have been approved.

15. Changes to this Policy

We may update this Return & Refund Policy when our products, services or legal requirements change. The new version will be posted on this page with a new "last updated" date. The version in force when we accept your order applies to that order.
