Shipping.

1. Order Processing

Ships within 1 business day. Orders are picked, packed, and dispatched after payment. Orders placed after the daily cutoff, on weekends, or on U.S. holidays begin processing the next business day. You will receive an order confirmation email immediately and a shipping confirmation with tracking once the package is handed to the carrier.

2. Carriers & Transit Times

We ship with tracked USPS and UPS services. Standard delivery typically arrives in 3–7 business days and express service in 2–4 business days after dispatch. Transit times are carrier estimates and are not guaranteed during severe weather or peak holiday volume.

3. Packaging

Every item ships factory-sealed with rigid protective inserts, and temperature-sensitive items include insulation matched to the transit window. Outer packaging is plain and unbranded to protect your privacy in shared receiving areas.

4. Storage on Arrival

Recommended storage conditions for each item are listed on its product page. Please move your order into the listed storage conditions promptly on arrival so the material stays within its stated specification.

5. Addresses, Delays & Delivery Issues

Please double-check your shipping address at checkout — we can update it before dispatch if you email us quickly. If a package is delayed, shows no tracking movement for 10 business days, arrives damaged, or is marked delivered but missing, contact support@northstarbiolabs.com and we will open a carrier claim and reship or refund under our Returns & Refunds policy.
