Shipping & Delivery Policy

Last Updated: October 20, 2026

At AMPSOS, operated by SUNEU LLC, we are committed to providing reliable shipping services and transparent delivery information. This policy explains how orders are processed, how shipping charges are calculated, and what customers can expect after their orders are shipped.

1. Order Processing Time (Handling Time)

• Business Days: Monday through Friday, excluding applicable public holidays.
• Order Cut-off Time: 5:00 PM Pacific Time, Monday through Friday.
• Orders placed after the daily cut-off time, on weekends, or on applicable public holidays begin processing on the next business day.
• Handling time refers to the time required to prepare an order and hand it over to the shipping carrier. It does not include the carrier's transportation time.

2. Shipping Rates & Charges

Shipping charges are calculated based on shipment weight and delivery destination.

The applicable shipping charge is calculated using the shipping rates configured for the destination and shipment weight. The actual shipping cost is displayed during checkout before payment is completed.

Shipping charges may vary depending on the total shipment weight, destination, and available shipping services.

3. Estimated Shipping Transit Times

Once an order has been handed over to the shipping carrier, the delivery process is managed by the carrier. Transit times depend on the destination, shipping service, customs procedures, and carrier operations.

The transit times above are estimates only and do not include order handling time. They are not guaranteed delivery dates. Actual delivery times may vary by carrier, service, and destination.

4. Shipping Destinations & Availability

AMPSOS serves customers in the United States and selected international markets, subject to shipping availability, product eligibility, and applicable transportation restrictions.

Available shipping destinations and applicable shipping charges are determined during checkout.

Certain energy storage products and products containing lithium batteries may be subject to additional carrier or destination-specific restrictions.

5. Order Tracking

Once your order has been shipped, you will receive a shipping confirmation email containing the tracking information when available.

You can track your shipment through the shipping carrier's tracking service.

6. Customs, Import Duties & Taxes

International orders may be subject to import duties, customs clearance fees, or destination-country taxes.

Unless otherwise stated at checkout, applicable import duties, customs charges, and destination-country taxes are the responsibility of the customer.

Customs processing requirements may affect delivery times.

7. Delivery Delays & Carrier Responsibilities

AMPSOS is responsible for processing orders and handing them over to the shipping carrier within the stated handling times.

After carrier handover, the shipping carrier performs transportation and delivery services.

Delivery delays may occur due to customs clearance, extreme weather, carrier operations, or other circumstances beyond our control.

If your shipment is significantly delayed or appears to be lost, please contact AMPSOS Customer Support. We will assist with shipment inquiries and carrier follow-up where appropriate.
