Dual Aminos — Shipping Policy
Dual Aminos ships orders within the United States using major carriers based on destination and service availability. USPS may be used for shipments to P.O. Boxes.
Orders placed by 1:00 PM CT on business days typically ship the same day. Orders placed after this time, or on weekends and holidays, ship the next business day. In some cases, processing may take 1–3 business days depending on order volume and product availability.
We offer free standard shipping on qualifying U.S. orders over $150. Shipping rates and carrier options may vary and are subject to change. Expedited options, including overnight delivery when available, may be selected at checkout.
All orders are shipped in discreet packaging. Optional shipping insurance may be selected at checkout at the customer’s expense when offered.
Due to the sensitive nature of our products, any shipping-related issues must be reported within 72 hours of delivery and may require photo documentation for review. Contact support@dualaminos.com with order number, photos, and a brief description of the issue.
Once an order ships, risk of loss generally transfers to you as described in our Terms & Conditions. We are not responsible for carrier delays, customs seizures, or refused shipments due to regulatory restrictions in your jurisdiction.
Returns: Due to the nature of research materials, all sales are generally final. Limited exceptions for damaged, defective, or incorrectly shipped items are described in our Return & Refund Policy.
All shipments are subject to our Terms & Conditions and Research Use Only Disclaimer.
