Last Updated: September 23, 2026
This Return & Refund Policy applies to purchases made through https://tiengu.com, operated by Nan’an Tingfengzhe Communication Equipment Co., Ltd. (南安听风者通讯设备有限公司), trading as SHJ Communications.
- Return Period
We accept eligible return requests submitted within 30 calendar days after the customer receives the product.
To request a return, please email dxu76256@gmail.com before sending any product back. Include the following information:
• Order number
• Customer name
• Product name and model
• Reason for the return
• Photographs or videos showing any damage, defect, incorrect item, or missing components
Returns sent without prior authorization may not be accepted.
- Return Eligibility
To qualify for a return, the product must generally:
• Be returned in its original condition
• Be free from avoidable damage or excessive wear
• Include the original packaging, manuals, accessories, cables, batteries, chargers, and other supplied components
• Include proof of purchase or the relevant order number
Customers may inspect a product as reasonably necessary to confirm its nature, characteristics, and operation. A deduction may be made where permitted by law if the product has lost value because of handling beyond what is reasonably necessary.
- Damaged, Defective, Incorrect, or Incomplete Orders
Please inspect your order promptly after delivery.
If the product arrives damaged, defective, incomplete, or different from the product ordered, contact us at dxu76256@gmail.com as soon as possible.
Please provide clear photographs or videos of:
• The shipping package
• The shipping label
• The product received
• The damaged or defective area
• All items included in the package
After reviewing the evidence, we may provide troubleshooting support, replacement parts, a replacement product, a partial refund, or a full refund, depending on the circumstances and applicable law.
When the return results from our error or a confirmed product defect, we will bear reasonable authorized return-shipping costs where required.
- Change-of-Mind Returns
Eligible physical products may be returned within the applicable return period if the customer changes their mind.
Unless required otherwise by applicable law:
• The customer is responsible for return-shipping costs
• Original shipping charges are generally non-refundable
• Customs duties, import taxes, currency-conversion charges, and bank fees are generally non-refundable by us
• The customer is responsible for ensuring that the return package is properly packed and reaches the approved return address
For customers protected by mandatory consumer laws, including eligible consumers in the European Union, statutory withdrawal rights remain unaffected. EU consumers generally have a 14-day right to withdraw from eligible online purchases, subject to applicable exceptions.
- Return Authorization and Address
Do not return products to the address shown on the shipping label without contacting us first.
The appropriate return address may depend on the customer’s location, the product, and the warehouse that fulfilled the order.
After approving the return request, we will provide:
• Return instructions
• The authorized return address
• Any required return reference or authorization information
We are not responsible for products returned to an unauthorized or incorrect address.
- Return Shipping
Customers should use a trackable shipping service and keep the shipping receipt and tracking information until the return is completed.
We are not responsible for return packages lost or damaged in transit when the customer arranged the return shipment.
Cash-on-delivery or postage-due return packages may be refused unless we approved the arrangement in writing.
- Non-Returnable Items
Unless defective or otherwise required by applicable law, the following items may not be eligible for return:
• Customized, personalized, or specially configured products
• Products damaged through misuse, improper installation, unauthorized modification, accident, neglect, or failure to follow instructions
• Products missing supplied components, serial numbers, labels, or original accessories
• Clearance or final-sale products identified as non-returnable before purchase
• Gift cards
• Software license keys that have been activated or redeemed
• Downloadable files that have already been accessed or downloaded, subject to applicable law
• Items that cannot be returned for health, safety, security, licensing, or regulatory reasons
- Software and Digital Downloads
Before purchasing or downloading software, firmware, manuals, programming files, or other digital content, customers are responsible for checking product-model and system compatibility.
Digital products that have not been downloaded, accessed, activated, or delivered may be eligible for cancellation and refund.
After a digital file has been downloaded, accessed, delivered, or a license key has been activated, the purchase is generally non-refundable unless:
• The digital content is defective
• The customer received the incorrect file
• The content is materially different from its description
• A refund is required by applicable law
Where required by law, immediate access to digital content may require the customer’s express consent and acknowledgment that the applicable cancellation or withdrawal right may be lost once delivery or downloading begins.
- Radio Equipment and Regulatory Compatibility
Customers are responsible for confirming before purchase that radio equipment, frequencies, transmission functions, software, accessories, and intended uses comply with the laws and licensing requirements of their country or region.
A product is not considered defective solely because its transmission functions, frequencies, certification, programming, or use are restricted by local law, provided that the product supplied matches its description.
This provision does not limit any mandatory rights relating to incorrect, defective, or misdescribed products.
- Refund Inspection
After receiving a returned product, we will inspect it and notify the customer whether the refund has been approved.
If the return does not meet this policy, we may:
• Refuse the return
• Send the product back to the customer
• Deduct an amount reflecting missing components, avoidable damage, or reduced value where permitted by law
We will explain any material deduction or rejection.
- Refund Method and Processing Time
Approved refunds will normally be issued to the original payment method.
We generally process approved refunds within 5–10 business days after completing the return inspection. The customer’s bank, card issuer, or payment provider may require additional time to post the refund.
Shipping fees, customs duties, import taxes, bank charges, and currency-conversion fees are refundable only when required by applicable law or when expressly approved by us.
If the original payment method cannot receive the refund, we will contact the customer to arrange a lawful alternative.
- Order Cancellations
Customers may request cancellation by emailing dxu76256@gmail.com.
We will try to cancel orders that have not yet been processed or shipped. However, cancellation cannot be guaranteed after fulfillment has begun.
If an order has already shipped, the customer may need to receive it and request a return under this policy.
If we cannot fulfill or ship an order, we will cancel the affected item and refund the applicable amount, including charges required to be refunded by law.
- Exchanges
We do not guarantee direct exchanges.
Where appropriate, we may offer a replacement for a damaged, defective, or incorrect product. For a change-of-mind request, the customer may be asked to return the original product for a refund and place a new order.
- Undeliverable, Refused, or Unclaimed Packages
If an order is returned because of an incorrect or incomplete address, refusal of delivery, failure to collect the package, or failure to complete customs procedures, we may deduct the original shipping costs, return-shipping costs, customs charges, and other reasonable expenses from the refund where permitted by law.
- Mandatory Consumer Rights
This policy does not exclude, restrict, or replace any consumer rights that cannot legally be waived.
If the laws applicable to the customer provide stronger cancellation, return, repair, replacement, warranty, or refund rights, those mandatory rights will apply.
