Frequently Asked Questions
Find answers to common questions about Derkin products, vehicle compatibility, ordering, shipping, returns, and installation.
Do your products fit every version of the vehicle listed?
Vehicle fitment can vary by model year, trim level, market, factory configuration, and previous modifications. Please review the compatibility details and variant options on the product page before ordering. If you are unsure, contact us with your vehicle model, model year, trim level, and a photo of the installation area.
How do I choose the correct product variant?
Select the variant that matches your vehicle model, model year, body style, installation position, color, and finish. Please confirm all options before checkout. If you need help, contact us before placing your order.
Where does Derkin ship?
We currently ship to eligible addresses within the United States. Orders may ship from China or the United States. Available delivery methods and shipping charges are shown during checkout.
How long does order processing take?
Orders are normally processed within 2–5 business days, excluding weekends and public holidays. Processing time is separate from delivery time.
How long does delivery take?
After processing, estimated delivery normally takes 7–15 business days. Delivery estimates are not guaranteed arrival dates and may be affected by carrier delays, severe weather, address issues, or other events outside our reasonable control.
How can I track my order?
When tracking is available, we will send a shipping confirmation email after your order has been dispatched. Tracking information may take several business days to update after the carrier receives the shipment.
Why did my order arrive in separate packages?
Products from the same order may ship separately. When this happens, you may receive more than one tracking number. A partial delivery does not necessarily mean that an item is missing.
Can I change or cancel my order?
Contact us as soon as possible if you need to change the delivery address, product variant, or cancel an order. We can only guarantee a change or cancellation before the order enters processing or fulfillment.
What is your return policy?
You may request a return within 30 days after your order is marked as delivered. Products must normally be unused, uninstalled, unmodified, and returned with their original packaging and accessories. Please review our Refund Policy for full eligibility requirements and instructions.
Where do I send a return, and who pays the costs?
Approved returns must be sent to China. For returns due to a change of mind, incorrect option selection, or incompatibility that was accurately described on the product page, the buyer pays international return shipping. Derkin does not charge any restocking or return processing fee. For approved claims involving damage, defects, or incorrectly supplied products, Derkin covers reasonable return shipping. Contact us for authorization and instructions before sending a return.
What should I do if my item arrives damaged, defective, or incorrect?
Contact us within 7 calendar days of delivery. Include your order number and clear photos of the shipping package, shipping label, product, affected area, and included accessories. Keep all packaging until the claim is resolved.
Do products include installation service?
Installation service is not included unless a product page specifically states otherwise. Follow the supplied instructions and use professional installation when necessary. Always confirm that installation will not interfere with airbags, controls, sensors, visibility, or legally required equipment.
How do I contact Derkin?

Product selection and purchasing questions
Does the lowest displayed price include the main accessory?
Check the selected option before comparing prices. Some listings contain different items rather than color choices alone. For example, the 2025–2026 Defender charging dock listing includes charging dock options and separate fragrance refill packs. A refill pack is not a charging dock.
What if the product title and selected option show different model years?
Do not assume that the broader title confirms fitment for every option. Send Derkin the product name, selected option, vehicle model and model year, plus a photo of the installation area, and ask for clarification before ordering.
Does a carbon fiber texture option confirm genuine carbon fiber?
No. A texture or finish label describes appearance and does not by itself establish the underlying material. Check the material stated for the specific option; if it is unclear, ask before ordering.
What should I include in a bulk, sample or customization inquiry?
Include the product name or URL, selected option or SKU, required quantity, vehicle details, destination and any requested changes to the item or packaging. Ask for confirmation of availability, minimum order quantity, sample terms, specifications and lead time for that request. Do not assume that retail listing terms establish custom or bulk order terms.
Does Derkin manufacture products in its own factory?
Derkin sources products through partner factories. Derkin is an independent aftermarket store; vehicle compatibility descriptions do not establish affiliation with the vehicle manufacturer.
