Warranty Policy

1. Warranty Period

The applicable warranty period is stated in the quotation, order confirmation, invoice, product specification, or contract. If no period is stated for a standard product, the default limited warranty period is 12 months from delivery. Repaired or replacement products are covered for the remainder of the original warranty period unless agreed otherwise in writing.

2. What the Warranty Covers

The warranty covers material defects in workmanship or materials that existed when the product was supplied and become apparent during the applicable warranty period under proper storage, installation, and normal intended use. It does not guarantee compatibility with every system unless compatibility was expressly confirmed in writing.

3. What the Warranty Does Not Cover

The warranty does not cover:

• normal wear, cosmetic changes, or consumable components;
• incorrect termination, installation, wiring, voltage, cleaning, storage, or maintenance;
• misuse, abuse, accident, unauthorized modification, or repair;
• damage caused by third-party equipment, incompatible systems, environmental exposure beyond the specification, power events, or force majeure;
• customer-supplied designs or materials where the defect results from that supplied requirement; or
• products whose model, batch, or traceability markings have been removed or altered.

4. Making a Warranty Claim

Contact us in writing during the warranty period. Provide the order reference, model, batch or label information, affected quantity, installation and operating conditions, failure description, test results where available, and clear photographs or video. We may request reasonable troubleshooting, samples, or return of the affected product before confirming the claim.

5. Warranty Remedies

After verification, we may choose a commercially reasonable remedy such as technical guidance, repair, replacement, rework, account credit, or refund of the affected product price. The remedy will reflect the nature, extent, and verified cause of the defect. Replacement does not include unrelated installation, removal, labor, downtime, or third-party system costs unless expressly agreed in writing.

6. Shipping for Warranty Service

Do not return products without written instructions. Responsibility for diagnostic samples, return freight, replacement freight, customs, and insurance will be confirmed after initial review. When a covered defect attributable to us is verified, we will bear the reasonable shipping responsibility stated in the approved remedy. If no covered defect is found, the buyer may be responsible for related costs.

7. Limitation

This limited warranty is subject to applicable law and the accepted transaction documents. To the maximum extent permitted by law, it replaces other implied warranties for the same product. Nothing in this policy limits rights or liabilities that cannot lawfully be limited.
