Shipping policy

Last updated: September 12, 2026

Where we ship

We currently ship only to delivery addresses in the United States. We do not currently ship internationally, including to Canada, the United Kingdom, or European Union member states.

Availability for a specific United States address is confirmed at checkout. Certain remote areas, United States territories, military addresses, PO boxes, or other restricted destinations may be unavailable depending on the product and carrier.

Processing time

Orders are normally processed within 1–2 business days, excluding weekends and public holidays. Orders placed during high-volume periods may require additional processing time. You will receive a shipping confirmation when the order is dispatched.

Estimated delivery time

  • United States: approximately 3–7 business days after dispatch.

Delivery estimates are not guarantees. Carrier disruptions, weather, holidays, remote destinations, and events outside our reasonable control may cause delays.

Shipping charges

Available shipping methods and charges are displayed at checkout before payment. Any promotion for free or discounted shipping applies only under the terms shown with that promotion.

Tracking

When tracking is available, it will be included in the shipping-confirmation message. Tracking may take time to update after the carrier receives the parcel.

Shipping addresses and order changes

Customers are responsible for providing a complete and accurate delivery address. Contact service@regentint.com.tw as soon as possible to request a correction. We cannot guarantee changes after fulfillment begins and are not responsible for delays or losses caused by an incorrect address supplied by the customer.

Lost or damaged shipments

If tracking shows a delivery problem or the parcel arrives damaged, contact us promptly with your order number and relevant photos or carrier information. We will review the matter and assist with a carrier claim, replacement, or other remedy where appropriate.
