Shipping Policy

This Shipping Policy explains how oioeos® processes and ships orders placed through oioeos.com, including delivery estimates, shipping costs, tracking, and assistance with delivery issues.

oioeos® is owned and operated by Hangzhou Milai E-commerce Technology Co., Ltd.

Shipping at a Glance

Business days exclude weekends and applicable public holidays. Delivery timeframes are estimates rather than guaranteed arrival dates.

From Checkout to Dispatch

Order Confirmation

Choose your products, select any available options, and complete checkout using accurate contact, shipping, and payment information.

After your order is successfully submitted, a confirmation will be sent to the email address provided at checkout. Please review it promptly and contact us if any details need correcting.

Processing Your Order

Orders are typically processed within 1 business day after payment has been confirmed.

Orders placed on weekends or public holidays will generally begin processing on the next business day. Payment-verification issues or unexpected stock discrepancies may require additional time. If an unusual processing delay affects your order, we will contact you using the email address provided at checkout.

Fulfillment Locations

Orders may be fulfilled from our own facilities or partner facilities, depending on product availability, inventory location, and destination.

Items within the same order may ship from different facilities. Regardless of the fulfillment location, oioeos® remains your point of contact for order and delivery assistance.

Delivery Times

United States

Standard delivery within the United States generally takes 2–4 business days after dispatch.

Including 1 business day for processing, the total estimated time from payment confirmation to delivery is approximately 3–5 business days.

Any destination-specific restrictions or different estimates shown at checkout will apply to the relevant order.

International Destinations

Available destinations and shipping options are shown at checkout. International delivery estimates vary by destination, carrier service, customs processing, and local conditions.

The 3–5 business-day total estimate applies to eligible U.S. orders, not international shipments.

Shipping Costs & Free Shipping

Eligible orders totaling US$39 or more after discounts and before taxes and shipping charges qualify for free standard shipping, subject to any destination or product exclusions displayed at checkout.

For orders that do not qualify, the available shipping methods and charges will be shown before payment is completed.

Shipping costs may vary according to the destination, selected service, package weight, and order contents. Please review the final shipping charge in your checkout summary.

Tracking Your Shipment

Once your order has been dispatched and tracking information becomes available, we will email your shipping confirmation and tracking details.

Tracking may not update immediately after a shipping label is created. The carrier’s first scan and subsequent updates can take additional time to appear.

If your order ships in separate packages, you may receive a tracking number for each shipment.

Checking Your Delivery Details

Please provide a complete and accurate shipping address, including any apartment, suite, building, or access information required for delivery.

If you need to update your address, email service@oioeos.com as soon as possible with your order number and the corrected details. We will try to assist, but changes cannot be guaranteed once processing or shipment preparation has begun.

Additional shipping charges may apply if a parcel must be redirected or reshipped because the address supplied at checkout was incorrect or incomplete. Any applicable charges will be explained before reshipment is arranged.

Separate Packages

Some orders may be divided into multiple shipments because of stock availability, fulfillment locations, or packaging requirements.

Packages may arrive on different dates. You will not be charged additional shipping fees solely because we choose to split your order.

If Your Delivery Is Delayed

Carrier disruptions, severe weather, public holidays, customs inspections, remote locations, and unusually high shipping volumes can affect delivery estimates.

If your order has not arrived within the expected timeframe, or tracking has stopped updating for an extended period, contact service@oioeos.com with your order number and tracking information.

We will review the available information and, where appropriate, contact the carrier or fulfillment partner to investigate.

A Parcel Appears to Be Lost

Please contact us if you believe your parcel has been lost in transit. We will investigate with the relevant delivery partners and help determine an appropriate resolution.

Depending on the circumstances and investigation findings, this may include further delivery assistance, a replacement, or a refund, consistent with applicable policies and consumer rights.

Tracking Says “Delivered,” but You Cannot Find It

Please check:

• Your mailbox, entrance, porch, or other secure delivery areas.

• Your building’s reception desk, mailroom, or management office.

• Whether someone in your household or a neighbor accepted the parcel.

• Any delivery photograph or notice supplied by the carrier.

If you still cannot locate the parcel, contact us so we can review the delivery information and assist with the next steps.

A “delivered” tracking status does not automatically prevent us from reviewing a legitimate delivery concern.

Inspecting Your Skincare Order

Please inspect your parcel and products promptly after delivery.

If an item is missing, incorrect, damaged, leaking, or has a visibly compromised seal, contact us as soon as possible. Include:

• Your order number.

• A brief description of the issue.

• Clear photographs of the affected product, its packaging, and the shipping label, where available.

Please retain the item and packaging while we review the request. If a product is leaking or its protective seal is damaged, leave it unused while awaiting instructions.

Customs & Import Charges

International orders may be subject to import duties, taxes, customs inspections, or local handling fees imposed by the destination country.

Unless checkout states otherwise, these charges are the recipient’s responsibility. Customs processing may also extend delivery times, which we cannot control or guarantee.

Returns & Refunds

To request a return, email service@oioeos.com before sending any product back. Include your order number and the reason for your request.

Return eligibility, product-condition requirements, and any applicable return shipping costs are explained in our Return & Refund Policy. Our team will provide the appropriate instructions and designated return address.

Please do not use the registered business address below as a return address unless we specifically instruct you to do so.

After an eligible return has been received and reviewed, approved refunds will be issued to the original payment method. The time for funds to appear depends on your bank or payment provider.

Nothing in this policy limits any mandatory consumer rights that apply to your purchase.
