Shipping Policy
US-only shipping rules, processing times, carriers, rates, risk of loss, and how we handle lost, damaged, or undeliverable packages.
1. Where We Ship
We ship only to physical addresses within the 50 United States and the District of Columbia. We do not currently ship to U.S. territories, APO/FPO/DPO addresses, freight forwarders, or international destinations. Orders with shipping addresses outside our serviceable area will be canceled and refunded.
2. State Restrictions
We currently ship to all 50 United States and the District of Columbia without product-level state restrictions. However, laws governing the sale, possession, and interstate shipment of research chemicals can change, and it remains your responsibility to determine whether the Products you are ordering are lawful in your jurisdiction before placing an order. We reserve the right to refuse, cancel, or restrict any order based on the shipping address, and to add product-level state restrictions in the future without prior notice.
3. Order Processing Times
Orders are processed from our Texas fulfillment facility Monday through Friday, excluding federal holidays. Orders placed before 8:00 AM Central Time on a business day are typically processed the same day; orders placed after that cutoff or on weekends or holidays are processed on the next business day. During high-volume periods, promotional events, or inventory transitions, processing may take up to 1–3 additional business days.
If an item in your order is out of stock when we attempt to ship, we will contact you to offer a substitution, a partial ship with back-order, or a refund of the affected line item.
4. Carriers, Services, And Transit Times
We ship via the U.S. Postal Service (USPS) and, where available, additional carriers such as UPS or FedEx. Service options typically include:
- Standard (USPS Ground Advantage) – typical transit 2–5 business days within the contiguous U.S.
- 2-Day Air (UPS 2nd Day Air) – typical transit 2 business days.
- Overnight (UPS Next Day Air) – typical transit 1 business day.
Transit times are estimates from the carrier and are not guaranteed. Weather, carrier backlog, customs or regulatory holds, and force majeure events can cause delays for which we are not responsible.
5. Shipping Rates And Free Shipping
Shipping charges are calculated at checkout based on destination, weight, and service selected. We may offer free standard shipping on orders above a stated threshold; the current threshold is shown at checkout and is subject to change. Free-shipping offers apply only to addresses within our serviceable area and to the service level indicated at checkout.
6. Tracking
Once your order has been handed to the carrier, we will send a shipment confirmation email containing a tracking number. Please allow up to 24 hours for the first scan event to appear in the carrier’s tracking system. Please check the tracking link before contacting support about delivery timing.
7. Title And Risk Of Loss
Title and risk of loss pass to you when we tender the Product to the carrier at our facility. We are not responsible for any loss, damage, theft, or delay that occurs after carrier handoff, except as described in Sections 8 and 9 below.
8. Lost, Damaged, Or Stolen Packages
If your tracking shows delivery but you have not received the package, first check with household members, neighbors, and your building’s mailroom, then contact the carrier to open an investigation.
You must report a damaged, missing, wrong, or non-delivered order to info@zamabio.com within seven (7) daysof the delivery date shown on the carrier’s tracking (or, for non-delivered packages, within 21 days of the expected delivery date). Reports received after these windows may not be eligible for replacement or refund.
For damaged packages, please retain all packaging and include photos of the outer box, inner packaging, and the affected Product(s) with your report. We will assist you in opening a claim with the carrier and, once the claim is resolved or the investigation supports the claim, issue a replacement or refund per our Return & Refund Policy.
9. Refused, Undeliverable, And Returned Packages
You are responsible for providing a complete, accurate shipping address and for being available to receive delivery. If a package is refused on delivery, marked undeliverable by the carrier, returned because no one was available to sign, or returned to us due to an incorrect or incomplete address provided at checkout, we may:
- re-ship the order once the correct address is confirmed, at your expense for the new shipping label; or
- cancel the order and refund the Product subtotal less shipping costs and a restocking fee (where permitted) at our discretion.
10. PO Boxes And Address Accuracy
USPS services deliver to PO Boxes; UPS and FedEx generally do not. Orders shipping via UPS or FedEx must be addressed to a physical street address. You are responsible for ensuring the address you provide at checkout is complete, current, and correct.
11. Research Use Only
All Products shipped are sold strictly for in-vitro laboratory research. See our Research Use Only Disclaimer and our Terms of Service.
