Shipping Policy

Last updated: August 31, 2026

SEFINN FOUR is operated by Tianjin Haimaotong Information Technology Co., Ltd. Customer orders are fulfilled from warehouse locations in the United States.

Free Standard Shipping on Orders $100+

Orders with an eligible merchandise subtotal of US$100 or more qualify for free standard shipping where offered at checkout. The qualifying subtotal is calculated after applicable product discounts and before taxes. For orders below US$100, any applicable shipping charge is shown at checkout before payment.

Order Processing

Orders are generally processed within 1–2 business days. Business days are Monday through Friday, excluding applicable holidays. Orders placed on weekends or holidays begin processing on the next business day.

Estimated Delivery Time

After processing, standard U.S. transit time is generally 3–7 business days. The estimated total delivery time is therefore generally 4–9 business days from the date the order is placed. These are estimates rather than guaranteed delivery dates.

U.S. Fulfillment

Orders sold through our U.S. storefront are shipped from U.S. warehouse locations. Some orders may ship in more than one package or from more than one U.S. warehouse depending on inventory availability.

Delivery and Tracking

When tracking information becomes available, it will be sent using the contact information provided with your order. Carrier scans can take time to update after a shipment is created.

Shipping Destinations and Charges

Available shipping methods, rates, and destination eligibility are displayed at checkout. Certain remote areas or oversized products may have different service availability or charges; any applicable charge is presented before the order is placed.

Address Accuracy

Please review your shipping address carefully before completing checkout. If you notice an error, contact us as soon as possible. We cannot guarantee an address change after an order has entered processing or shipment.

Delays

Transit times may be affected by carrier volume, weather, service interruptions, remote-area delivery, or other circumstances outside our reasonable control. If a shipment appears significantly delayed, contact us and we will help review the available tracking information.

Damaged or Missing Packages

If a package arrives visibly damaged, retain the packaging and contact us within 7 days of delivery with your order number and photos. If tracking shows delivery but you cannot locate the package, first check the delivery area and with household members or neighbors, then contact the carrier and email us for assistance.
