Return & Refund Policy

Return eligibility

For a change-of-mind return, items should be unused, in their original condition, with packaging and any included components. Keep your order confirmation or other proof of purchase. Please tell us about any use, damage or missing packaging when requesting a return so we can assess it fairly.

How to request a return

1. Email service@birchwhistle.com within 30 days of delivery, including your order number, item and reason.
2. Wait for return instructions before posting. We may ask for photographs to understand a defect or wrong item.
3. Pack securely, use a trackable shipping service and retain the receipt.

Return address: Hangzhou Xi'an Technology Co., Ltd., Room A0027, Building 1, No. 298 Yunxi Road, Cangqian Street, Yuhang District, Hangzhou City, Zhejiang Province, China. Returns are sent to China; consider international postage costs before requesting a change-of-mind return.

Who pays return postage?

Customers pay return postage for personal preference, ordering the wrong item or other change-of-mind reasons. Original delivery charges are generally not refunded for these returns unless required by law. For damaged, defective or incorrectly supplied items, contact us first; we will assess the circumstances and cover reasonable return costs where we are responsible or law requires. Do not incur special shipping charges without contacting us.

Inspection and refunds

We inspect returns and process approved refunds within 10 business days after receiving the returned goods. Approved refunds go to the original payment method. Your bank or payment provider may take additional time to post the credit. We will explain any rejected or adjusted refund and its reason.

Damage, exchanges and cancellations

Report damage, defects or a wrong item as soon as you discover the issue. Keep the item and packaging while we investigate. For an exchange, contact us to discuss availability; a return and separate order may be required. Email cancellation requests promptly. Orders already dispatched must follow the return process.

Your statutory rights

This policy does not limit mandatory consumer rights, including remedies for goods that are defective, misdescribed or otherwise fail applicable legal requirements. Any policy exception applies only where permitted by law.
