Contrastech accepts return or exchange requests only for product defects or quality issues, subject to review and confirmation.

Returns or exchanges for reasons unrelated to product defects or quality issues are generally not accepted, subject to applicable law.

2. Non-Eligible Return and Exchange Requests

Before placing an order, customers are responsible for confirming that the selected product meets their technical requirements and is suitable for their intended application. Customers are also responsible for evaluating product compatibility with their systems and use cases.

Requests based on the following reasons are generally not eligible:

• Misunderstanding product specifications or selecting the wrong product.
• Product incompatibility with the customer's intended application.
• Personal dissatisfaction unrelated to a confirmed product defect or quality issue.

These limitations are subject to any mandatory rights or remedies available under applicable law.

3. Product Quality and Claim Period

Our products undergo quality control and quality assurance inspections before shipment. However, if a product you receive is damaged, defective, or materially inconsistent with its published description, please contact us within 3 business days of receipt to report the issue.

Our team will review the information provided and advise you on the next steps. Please do not return any product before receiving return instructions from our team.

The stated reporting period does not limit any non-waivable rights you may have under applicable law.

Please note that a 6.4% transaction processing fee charged by the payment platform is non-refundable and may be deducted from the refund amount, where permitted by applicable law and the relevant payment provider's terms.

The actual time required for the refunded amount to appear in your account may vary depending on your payment provider or bank.
