Reach Customer Care

For product questions, orders, shipping, tracking, returns, refunds, payment concerns, or privacy requests, email service@ouiavna.com or call +86 13596640349.

Our customer service hours are Monday–Friday, 9:00 AM–6:00 PM PST. We generally aim to respond to inquiries within 1–2 business days.

Help us find your order

Please include the order number, the email address used at checkout, a clear explanation of the question or issue, and relevant photographs or video where appropriate.

Delivery and tracking questions

Most in-stock orders are prepared within 1–3 business days after payment authorization. Standard U.S. carrier transit is generally estimated at 5–12 business days after dispatch. Checkout shows the available delivery services and charges before payment. Fulfillment can be through our own operations or appropriate partners, depending on inventory and destination. When tracking is available, allow approximately 48 hours after label creation for the first carrier activity.

Contact us if tracking remains unchanged for an extended period or delivery is significantly outside its expected range. You can also contact us about a missing parcel marked “Delivered.” We may ask you to check the delivery area, household members, reception desk, neighbors, or local carrier while we review the circumstances.

Returns and product concerns

Eligible products may be returned within 30 calendar days after confirmed delivery. Contact us before sending merchandise for a review and, if approved, the correct return warehouse address and instructions. The business registration address is not an automatic return destination.

Preference-based return postage is generally the customer’s responsibility. For confirmed damaged, defective, incorrect, incomplete, or materially misdescribed goods, we provide an appropriate replacement, refund, or return solution without making you bear the reasonable return cost caused by the issue. Approved eligible returns have no separate restocking fee.

Refund timing and order changes

Authorized returns are normally inspected within 5 business days after reaching the designated facility. Following approval, refunds are issued to the original payment method within 1–3 business days; a payment provider may need additional time to post the credit.

Request a change or cancellation within 12 hours after purchase. Once processing, fulfillment, shipping preparation, or dispatch has begun, a request cannot be guaranteed. No separate cancellation fee is charged merely for submitting an eligible request.

Payments and privacy

Checkout may offer major credit cards, debit cards, PayPal, or other supported methods enabled for your location. Transactions are processed in United States Dollars (USD). For privacy access, correction, deletion, or other data requests, email service@ouiavna.com. Identity verification may be needed depending on the request and applicable law.
