Shipping Policy

Last updated: August 13, 2026

This policy applies to orders placed with the ZENHAX online store operated by WONDFUL (HK) TECHNOLOGY LIMITED. Our United States warehouse is the primary fulfillment location for North American orders.

1. Shipping destinations

We ship to supported destinations in North America when an available shipping method is presented at checkout. Available destinations, carriers, methods, charges, and restrictions can vary by product and delivery address.

2. Shipping charges by product category

• Complete head units and complete car stereo systems: eligible products include free standard shipping to supported North American checkout zones unless the product page or checkout states otherwise.
• Dash kit bundles, fascia and wiring kits, frames, harness kits, CAN Bus or protocol-box kits, and other vehicle-specific installation kits: shipping is charged separately according to destination, packed weight, package dimensions or dimensional weight, carrier service, and fulfillment location.
• Mixed orders: a paid shipping rate may still apply to the dash-kit, frame, harness, or installation-kit portion of an order that also contains a free-shipping head unit.

The shipping amount displayed and accepted at checkout is the charge for that order unless a clear pricing or address error requires customer approval before fulfillment. We will not add an undisclosed shipping charge after payment without first obtaining the customer's agreement.

3. Processing and delivery estimate

Orders generally arrive within 7–10 business days after order confirmation. This is an estimate rather than a guaranteed delivery date. Weekends, public holidays, vehicle-fitment verification, delayed customer responses, remote-area service, address correction, customs or border review, severe weather, carrier disruption, and unusually high order volume may extend delivery time.

When an accepted order cannot be delivered within the stated estimate, we will notify the customer, provide a revised estimate when available, and offer the delay, cancellation, or refund options required by applicable law.

4. Vehicle and order verification

Vehicle-specific products may require confirmation of make, model, year, trim, factory audio system, steering position, connector type, region, or other configuration. Please provide complete and accurate details. Missing or inconsistent information may delay processing while we contact you.

5. Tracking and delivery

When tracking is available, it will be sent to the email address or customer account associated with the order. Carrier scans may take time to appear. If tracking shows delivery but the parcel cannot be located, check the delivery area, household members, building staff, parcel lockers, and carrier notices before contacting us.

6. Address accuracy, loss, and damage

The customer is responsible for providing a complete, accurate, and deliverable address. The customer bears additional carrier, return-to-sender, and reshipment charges caused by an incorrect or incomplete customer-supplied address, refused or unclaimed delivery, or a customer-requested address change after carrier handoff. ZENHAX bears authorized costs when the address or label error was ours.

For loss, misrouting, or damage confirmed to have occurred while the parcel was in the carrier's custody, ZENHAX will coordinate the claim and authorized remedy. Keep the product, packaging, label, and all contents while an investigation is open.

7. Return shipping responsibility

• ZENHAX pays authorized return shipping: for a verified product defect or quality problem that prevents normal use, a wrong item shipped by us, a verified missing listed component, or a product mismatch after the customer supplied complete and accurate vehicle information and ZENHAX confirmed compatibility in writing.
• The customer is responsible for authorized return shipping: when a normally functioning product is returned because of dissatisfaction, change of mind, a wrong selection, inaccurate or incomplete vehicle information, an undisclosed vehicle modification, or an actual vehicle configuration that differs from the information supplied before purchase.

A refund is not available when customer-caused installation, modification, misuse, damage, contamination, missing parts, or other customer-caused handling leaves the product unsuitable for resale, except where applicable law requires otherwise. Reasonable installation or testing does not automatically prevent a return when a product problem is discovered. See the Return and Refund Policy for the complete return authorization and inspection rules.

8. Split shipments, duties, and customs

Items in one order may ship separately and may have more than one tracking number. Unless checkout states otherwise, customers are responsible for import duties, taxes, brokerage fees, customs charges, and government assessments imposed by the destination.
