After your order is shipped, your will receive another email from us with the tracking information.

You can find tracking information in your order details. If an order includes multiple items, each may have separate delivery dates and tracking information.

Some packages, such as standard international deliveries, aren't trackable.

If the estimated delivery date for your package has passed and your tracking information hasn't changed, allow an additional day or two for the package to be delivered. 

Here are some reasons why tracking information may not be available:

-The first package scan may be on arrival at a regional hub near the destination. This is common when shipping volume is high and packages are processed in bulk. Until this first scan, the carrier may not acknowledge receipt of the package.

-The first package scan may not be until delivery.

-There may be a delay in updates to the tracking database.

-Some shipments, such as Standard International shipments, aren't trackable.

-Marketplace sellers don't always provide us with tracking information for their orders.

If the estimated delivery date for your package has passed, and your tracking information hasn't changed, allow an additional day or two for the package to be delivered. Usually, packages arrive on or shortly after the estimated delivery date.

Possible reasons for late delivery include the following, you could contact us by [email protected] to check the status or call the local express service to check. 

-Incorrect address

-Missing apartment, building, floor, or unit number

-Severe weather conditions

-International customs procedures

If your tracking information shows that your package was delivered, but you can't find it within 48 hours of expected delivery, we suggest you follow the following guide:

-Verify the shipping address in Your Orders.

-Look for a notice of attempted delivery.

-Look around the delivery location for your package.

-See if someone else accepted the delivery, unless you have health or safety concerns about doing so.

-Some packages travel through multiple carriers; check your mailbox or wherever else you receive mail.

-Wait 48 hours. In rare cases, packages may say delivered up to 48 hours before arrival.

Note: Some carriers may deliver until 10 pm.

Below are some steps and suggestions on how you can solve this issue:

-Check your shipping address and phone number for delivery.

-Contact local delivery provider with the tracking number.

All orders reported as "delivered" by shipping companies are considered delivered. Sunthen cannot be made liable for non-delivery in this case. If you have any further inquiries, please contact us without hesitation.

Occasionally, packages are returned to us as undeliverable.

When the carrier returns a package as undeliverable, we automatically begin issuing a full refund (including shipping charges, except for some handling charges). You receive an email confirming the return and refund details within 48 hours of the undeliverable scan. For information about the time it takes to process your refund, go to Refunds.

Note: To see the refund status of your order after the item was returned to us, go to Your Orders.

A package might be returned as undeliverable for several reasons:

-The address is incorrect or outdated. Usually, the package is stored for a period that can vary depending on the courier who holds it and then returns it to us. Double-check the address carefully when placing your order.

-Our system doesn't recognize the way an address was entered, or the package was assigned to a carrier that can't deliver to that address.

-You used a restricted address. If you send the order to a prison, correctional facility, or other similar institution, the products and/or the carrier responsible for delivery may be subject to specific restrictions.

-The carrier attempted delivery but failed. Most of our carriers make more than one attempt to deliver a package. If they find that they can't successfully deliver your package, they'll return it to us.

-The recipient refused the delivery. A gift recipient who isn't expecting a gift may refuse a package if they believe it's being delivered to them by mistake. In this case, we'll refund the gift purchaser and let them know by email. If you want to place a new order for the gift, you may want to let the recipient know that a surprise is on the way.

-The address was illegible. In rare cases, address labels may become impossible to read in transit. If that happens, a carrier will return the package to us.

-The package was damaged in transit. If a package is damaged while it's on its way to you, the carrier may return it without attempting delivery.

We can't re-ship orders that carriers return to us as undeliverable. If you still want to purchase items that were undeliverable, place a new order on our website.

If you suspect your order can't be delivered as addressed, and you haven't received confirmation of its return or refund four weeks after from the estimated delivery date, please contact us.
