Shipping & Returns Policy

Last updated: July 10, 2026

This Shipping & Returns Policy explains the shipping, delivery, cancellation, return, exchange, and refund terms that apply to purchases from DST – DeutschTuning Softwares & Technologies (“DST,” “we,” “us,” or “our”).

This policy applies to physical products, diagnostic hardware, cables, adapters, interfaces, tools, software licenses, digital downloads, activation services, remote-support services, and related products purchased through our website.

By placing an order, you agree to this policy.

1. Order Processing

Orders are normally reviewed and processed after payment authorization and any required fraud, compatibility, address, or identity verification.

Estimated processing times may vary depending on:

  • Product availability
  • Order volume
  • Payment verification
  • Fraud screening
  • Product configuration
  • Software-license activation
  • Custom programming or preparation
  • Supplier or warehouse availability
  • Weekends and holidays

Physical products that are in stock generally begin processing within 1–4 business days.

Processing time is separate from carrier transit time.

2. Business Days

Business days are Monday through Friday, excluding United States federal holidays and days when DST or its fulfillment partners are closed.

Orders placed after the applicable daily cutoff time may begin processing on the next business day.

3. Shipping Locations

DST may ship to locations within the United States and to selected international destinations.

Shipping availability depends on:

  • Product restrictions
  • Carrier availability
  • Export-control requirements
  • Customs requirements
  • Delivery-address verification
  • Fraud-screening results
  • Manufacturer or distributor restrictions

We may decline or cancel orders to locations we cannot reliably or lawfully serve.

4. Shipping Rates

Shipping charges are calculated or displayed at checkout based on factors such as:

  • Delivery address
  • Product weight
  • Package dimensions
  • Shipping method
  • Carrier
  • Insurance
  • Signature requirements
  • International duties or handling

Any shipping promotion, free-shipping offer, or discounted rate is subject to the stated terms of that promotion.

5. Estimated Delivery Times

Any delivery date shown at checkout or in an order confirmation is an estimate unless expressly guaranteed in writing.

Carrier delays may occur because of:

  • Severe weather
  • Holidays
  • Customs inspections
  • Transportation disruptions
  • Labor disputes
  • Incorrect or incomplete addresses
  • Remote delivery locations
  • Security inspections
  • Carrier capacity
  • Government action
  • Events beyond our control

DST does not guarantee delivery by a particular date unless a written guaranteed-delivery service is expressly purchased and accepted.

Federal rules generally require online sellers to have a reasonable basis for the promised shipping period. When no shipping period is stated, the default federal expectation is generally shipment within 30 days; if shipment cannot occur as promised, the seller generally must obtain consent to the delay or provide a refund for the unshipped merchandise.

6. Tracking Information

When tracking is available, it will generally be sent to the email address or telephone number associated with the order.

Tracking information may take time to update after a shipping label is created.

A label being created does not necessarily mean the carrier has physically received or scanned the package.

7. Address Accuracy

You are responsible for providing a complete and accurate:

  • Recipient name
  • Street address
  • Apartment, suite, or unit number
  • City
  • State or province
  • Postal code
  • Country
  • Telephone number
  • Email address

Contact DST immediately if an address correction is needed.

We cannot guarantee that an address can be changed after an order enters processing or fulfillment.

Additional shipping, interception, redelivery, or return-to-sender charges caused by an incorrect or incomplete address may be charged to the customer where permitted by law.

8. Signature Requirements

Certain high-value, sensitive, licensed, or fraud-risk orders may require an adult or direct signature.

The customer is responsible for ensuring that an authorized recipient is available.

Failure to accept or collect a package may result in return-to-sender fees, reshipping fees, or other carrier charges.

9. Lost, Stolen, or Missing Packages

If tracking indicates that a package is delayed, missing, or delivered but not received, contact DST promptly.

We may ask you to:

  • Confirm the delivery address
  • Check with household members or employees
  • Check surrounding delivery areas
  • Contact the carrier
  • File a carrier claim
  • Provide a signed statement
  • File a police report for suspected theft
  • Provide other reasonable documentation

DST will assist with eligible carrier investigations, but replacement or refund eligibility depends on the facts, carrier findings, insurance coverage, applicable law, and whether delivery was properly completed.

10. Damaged Shipments

Inspect the package and products promptly after delivery.

Report visible shipping damage, missing components, or materially damaged products within 3 business days after delivery.

Include:

  • Order number
  • Description of the damage
  • Photographs of the product
  • Photographs of the shipping carton
  • Photographs of the shipping label
  • Photographs of internal packaging
  • Serial number, when applicable

Keep all packaging until DST or the carrier completes its review.

Discarding packaging may affect claim eligibility.

11. International Shipping

International customers are responsible for understanding and complying with local import requirements.

International orders may be subject to:

  • Customs duties
  • Import taxes
  • Value-added tax
  • Brokerage charges
  • Clearance fees
  • Storage fees
  • Local handling charges
  • Product restrictions
  • Customs delays

Unless expressly stated otherwise, these charges are not included in the product or shipping price and are the customer’s responsibility.

DST is not responsible for delays caused by customs or for orders refused, abandoned, seized, or returned because the customer failed to pay import charges or satisfy local requirements.

12. Customs Value and Documentation

DST will not intentionally falsify customs declarations, product values, classifications, origin information, or shipping documentation.

Requests to mark commercial merchandise as a gift or declare a false value will be refused.

13. Delivery Refusal and Returned Packages

If a package is refused, unclaimed, undeliverable, or returned because of an incorrect address, the customer may be responsible for:

  • Original shipping charges
  • Return shipping charges
  • Customs or brokerage charges
  • Carrier fees
  • Reshipping charges
  • Reasonable restocking charges, where disclosed and permitted

Any eligible refund may be reduced by such charges to the extent permitted by law.

14. Order Changes and Cancellations

Contact DST as soon as possible to request an order change or cancellation.

An order cannot be guaranteed to be changed or canceled after it has:

  • Entered fulfillment
  • Been packed
  • Been shipped
  • Been submitted to a supplier
  • Been specially ordered
  • Been configured
  • Been programmed
  • Been activated
  • Been digitally delivered
  • Entered remote-support processing

Approved cancellations may be subject to non-refundable processing costs where permitted and clearly disclosed.

15. Return Window for Eligible Physical Products

Eligible physical products may be returned within 14 days after confirmed delivery.

A return must be requested and authorized before the product is sent back.

Products returned without authorization may be refused or delayed.

Shopify allows merchants to configure return windows, return-shipping costs, and restocking fees in store return rules.

16. Return Eligibility

To qualify for a return, a physical product must generally be:

  • In new or resalable condition
  • Unused
  • Uninstalled
  • Unprogrammed
  • Unmodified
  • Free of damage
  • Free of marks, contamination, or wear
  • Complete with all components
  • In its original packaging
  • Accompanied by proof of purchase
  • Returned with the issued authorization

Serial numbers, security seals, identifiers, and included accessories must match the original order.

DST may inspect and test returned products before approving a refund.

17. Non-Returnable Products and Services

Unless required by law or expressly approved by DST, the following are final sale and non-returnable:

  • Downloaded software
  • Delivered digital files
  • Software licenses
  • Activated licenses
  • Activation codes
  • Login credentials
  • Subscription periods already started
  • Custom software configurations
  • Custom programming
  • Calibration or coding files
  • Remote-support services already started or completed
  • Installation services
  • Diagnostic services
  • Special-order products
  • Custom-built cables or harnesses
  • Opened electrical components
  • Installed electronic products
  • Used cables, interfaces, adapters, or tools
  • Products with broken or removed security seals
  • Products damaged by incorrect wiring, voltage, installation, coding, programming, or use
  • Clearance or final-sale products, when identified as such
  • Gift cards
  • Products prohibited from return for health, safety, licensing, or legal reasons

18. Software and Digital Products

Because software and digital products may be copied, accessed, activated, or downloaded immediately, they are generally non-refundable once any of the following occurs:

  • The download link is delivered
  • The file is accessed
  • The software is downloaded
  • A license is generated
  • A license is activated
  • Credentials are issued
  • Installation begins
  • Remote support begins
  • A custom file is prepared
  • A configuration is completed

Before purchasing, verify:

  • Computer compatibility
  • Operating-system requirements
  • Hardware requirements
  • Vehicle compatibility
  • ECU or module compatibility
  • License duration
  • Device limits
  • Supported functions
  • Internet or activation requirements

A customer’s inability to use software because of an unsupported device, unsupported vehicle, insufficient technical skill, incompatible computer, third-party conflict, antivirus restriction, or failure to follow instructions does not automatically qualify the purchase for a refund.

19. Compatibility-Related Returns

Customers are responsible for reviewing product descriptions and confirming compatibility before purchase.

If DST expressly confirms compatibility in writing based on complete and accurate information supplied by the customer, and the product is materially incompatible, contact DST for review.

Compatibility returns may require:

  • Vehicle identification details
  • ECU or module part number
  • Hardware or software version
  • Photographs
  • Diagnostic logs
  • Screenshots
  • Installation details
  • Testing information
  • Cooperation with technical support

Products ordered without confirming compatibility may be subject to the normal return conditions, shipping charges, and restocking fees.

20. Return Authorization

To request a return, contact DST at:

Email: support@dstdiagnostic.com
Subject: Return Request – Order #[INSERT ORDER NUMBER]

Include:

  • Full name
  • Order number
  • Product name
  • Reason for return
  • Product condition
  • Photographs, where applicable
  • Serial number, where applicable

Do not ship a return until DST provides written authorization and return instructions.

21. Return Shipping

Unless the product was materially defective, damaged in transit, or incorrectly shipped by DST, the customer is responsible for return-shipping costs.

Original shipping charges are generally non-refundable.

Use a trackable and adequately insured shipping service.

DST is not responsible for return packages that are lost, damaged, misdirected, or delivered to an unauthorized address.

The FTC recommends that return policies clearly state who pays return shipping and whether restocking fees apply.

22. Restocking Fees

Eligible physical-product returns may be subject to a restocking fee of [INSERT FEE, such as 15%] when permitted by law and disclosed before purchase.

A higher deduction may apply when a product is returned:

  • With damaged packaging
  • Missing accessories
  • Missing documentation
  • Showing signs of handling
  • Requiring testing
  • Requiring reconfiguration
  • In a condition reducing resale value

Products that are materially used, damaged, altered, programmed, installed, or incomplete may be refused.

23. Inspection of Returns

Returned products are inspected before a refund or exchange is approved.

Inspection may include:

  • Serial-number verification
  • Physical-condition review
  • Functional testing
  • Accessory verification
  • Packaging review
  • License-status review
  • Security-seal inspection
  • Evidence of installation, programming, or misuse

DST will notify the customer if the return is approved, partially approved, or rejected.

24. Refunds

Approved refunds are issued to the original payment method unless otherwise required by law.

Processing time depends on:

  • Inspection completion
  • Payment provider
  • Bank
  • Card issuer
  • Shopify processing
  • Fraud or dispute status

DST may issue a partial refund when permitted due to:

  • Restocking fees
  • Missing components
  • Damage
  • Reduced value
  • Non-refundable shipping
  • Carrier charges
  • Customs charges
  • Return-to-sender costs

Shopify permits merchants to issue full or partial refunds and separately decide whether shipping fees are refunded.

25. Exchanges

Eligible physical products may be exchanged at DST’s discretion.

Exchange eligibility depends on:

  • Product condition
  • Availability
  • Price difference
  • Shipping costs
  • Compatibility
  • Inspection results

The customer may be responsible for return shipping, replacement shipping, and any difference in price.

26. Defective Products

If a product appears defective, contact DST before returning it.

Many reported defects are caused by:

  • Incorrect installation
  • Incorrect drivers
  • Unsupported software
  • Incorrect cable selection
  • Incorrect power supply
  • Insufficient voltage
  • Vehicle incompatibility
  • Incorrect ECU or module identification
  • Configuration errors
  • Third-party software conflicts

DST may require reasonable troubleshooting before approving a defective-product return.

A product that is confirmed defective may be repaired, replaced, exchanged, credited, or refunded depending on the applicable warranty and law.

27. Incorrect Items

If DST ships an item different from the item ordered, contact us promptly.

Do not install, activate, program, or use the incorrect product.

DST may provide a return label and arrange replacement after verifying the error.

28. Manufacturer Warranties

Some products may be covered by a manufacturer or distributor warranty rather than a direct DST warranty.

In those cases, the customer may be required to follow the manufacturer’s warranty process.

DST may assist with documentation but does not control the manufacturer’s eligibility decisions, repair periods, replacement availability, or warranty terms.

29. Chargebacks and Payment Disputes

Contact DST before initiating a payment dispute so we have an opportunity to investigate and resolve the issue.

Submitting a false, misleading, or unauthorized chargeback may result in:

  • Suspension of account access
  • Suspension of software licenses
  • Termination of support
  • Recovery of unpaid amounts
  • Submission of transaction and delivery evidence
  • Other lawful action

Nothing in this section limits any legitimate consumer right to dispute an unauthorized or improper charge.

30. Promotions, Clearance, and Final Sale

Products identified as:

  • Final sale
  • Clearance
  • Closeout
  • Open box
  • Used
  • Special order
  • Custom
  • Non-returnable

may have different return terms or may not be returnable.

The applicable terms will be stated in the product listing or at checkout.

31. Refused Refunds

A refund may be denied when:

  • The return is outside the stated window
  • The product is non-returnable
  • The product was used or installed
  • The product was programmed or activated
  • The security seal was removed
  • Parts or accessories are missing
  • The serial number does not match
  • The product was damaged by misuse
  • The return was sent without authorization
  • The return was sent to the wrong address
  • Fraud or abuse is reasonably suspected

32. Changes to This Policy

DST may update this Shipping & Returns Policy to reflect changes in:

  • Products
  • Carriers
  • Shipping locations
  • Return procedures
  • Shopify features
  • Business operations
  • Legal requirements

The revised policy becomes effective when posted with an updated date, unless applicable law requires additional notice.
