Shipping Policy
LAST UPDATED JULY 26, 2026
U.S. 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 ship to:
1. U.S. territories
2. APO/FPO/DPO addresses
3. freight forwarders
4. international destinations
Orders placed with addresses outside our serviceable area will be canceled and refunded.
2. State Restrictions
We currently ship to all 50 states and D.C. without product‑level restrictions.
However, laws governing research chemicals may change.
You are responsible for confirming that the Products you order are lawful in your jurisdiction.
We reserve the right to:
1. refuse or cancel any order based on the shipping address
2. add state‑specific restrictions at any time without prior notice
3. Order Processing Times
Orders are processed from our East Coast fulfillment workflow (EST) Monday through Saturday, excluding federal holidays.
Orders placed before 2:00 PM Eastern Time (Mon–Fri) are typically processed the same day.
Orders placed after 2:00 PM ET, or on Saturday after 12:00 PM ET, are processed the next business day.
USPS is closed on Sunday; all Sunday orders are processed Monday.
During high‑volume periods, promotional events, or inventory transitions, processing may take 1–3 additional business days.
If an item is out of stock at the time of shipping, we will contact you to offer:
1. a substitution,
2. a partial shipment with back‑order, or
3. a refund for the affected item.
4. Carriers, Services, and Transit Times
We ship primarily via the U.S. Postal Service (USPS).
Available services include:
1. USPS Ground Advantage — typical transit 2–5 business days
2. USPS Priority Mail — typical transit 1–3 business days
Transit times are estimates provided by USPS and are not guaranteed.
Weather, carrier backlog, operational delays, and force majeure events may extend delivery times.
5. Shipping Rates and Free Shipping
Shipping charges are calculated at checkout based on:
1. destination
2. package weight
3. service level selected
We may offer free standard shipping above a certain order threshold.
The current threshold is displayed at checkout and may change without notice.
Free shipping applies only to addresses within our serviceable area and only to the service level indicated.
6. Tracking
Once your order is handed to USPS, you will receive a shipment confirmation email containing a tracking number.
Please allow up to 24 hours for the first scan to appear in USPS’s tracking system.
Check the tracking link before contacting support regarding delivery timing.
7. Title and Risk of Loss
Title and risk of loss transfer to you once the package is tendered to USPS. We are not responsible for loss, damage, theft, or delay after carrier handoff, except as described in Sections 8 and 9.
8. Lost, Damaged, or Stolen Packages
If tracking shows “Delivered” but you have not received your package:
1. Check with household members, neighbors, or your building’s mailroom.
2. Contact USPS to open an investigation.
You must report any damaged, missing, wrong, or non‑delivered order to [email protected] within:
- 7 days of the delivery date shown in tracking, or
- 21 days of the expected delivery date for packages not marked delivered.
Reports submitted outside these windows may not be eligible for replacement or refund.
For damaged shipments, retain all packaging and include photos of:
1. outer packaging
2. inner packaging
3. affected product(s)
We will assist you in opening a USPS claim and issue a replacement or refund once the investigation supports the claim.
9. Refused, Undeliverable, and Returned Packages
You are responsible for providing a complete and accurate shipping address.
If a package is:
- refused,
- marked undeliverable,
- returned due to an incorrect address, or
- returned because no one was available to receive it,
We may:
1. re‑ship the order once the correct address is confirmed (new shipping label charged to you), or
2. cancel the order and refund the product subtotal minus shipping costs and any applicable restocking fee.
10. PO Boxes and Address Accuracy
USPS delivers to PO Boxes.
UPS and FedEx do not, but we currently ship USPS only, so PO Boxes are acceptable.
You are responsible for ensuring your address is:
1. complete
2. current
3. accurate
Orders shipped to incorrect addresses provided at checkout are not eligible for free replacement.
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.
