Shipping & Delivery
LAST UPDATED · October 26, 2026
We ship from our California facility to addresses within the United States. A tracking number is sent by email the moment a shipping label is printed.
1. Where we ship
CoreLabs currently ships only to the 50 U.S. states and U.S. territories with valid ZIP codes. We do not ship internationally at this time. Orders with a delivery address outside the United States cannot be fulfilled and will be cancelled and refunded in full.
2. Processing time
Orders are processed within 1–2 business days. Subscription refills are prioritized and typically ship same-day on their scheduled renewal date. You will receive a tracking number once your order leaves the facility.
3. United States shipping rates
Standard delivery (3–5 business days): $7.99. Free on every subscription order and on one-time orders of $50 or more after discounts.
Express delivery (1–2 business days): $15.99. Orders placed before 12:00 PM Pacific on a business day ship the same day.
Shipping is automatically calculated at checkout based on your selected method. Subscription orders always receive free shipping, regardless of order value.
4. Subscription shipments
Subscription orders are billed and shipped on the cadence you select at checkout — every 15, 30, 60, 90, or 120 days. Each recurring order ships with free Standard delivery. You can pause, skip, or change the frequency of any subscription from your account at any time.
5. Tracking your order
Use the Track Order page with your order ID and order key from the confirmation email, or view live status in your account at any time. A tracking link is also included in your shipping confirmation email.
6. Address accuracy and undeliverable packages
Please verify your shipping address before placing an order. We are not responsible for delays or lost shipments caused by an incorrect or incomplete address. If a package is returned to us as undeliverable, we will contact you to arrange reshipment; additional shipping charges may apply.
7. Delays
Carriers occasionally experience delays outside our control. If your order has not arrived within the quoted window plus 5 business days, contact support@corelabs.co and we will trace it with the carrier or replace it.
8. Order changes and cancellations
Because we process orders quickly, changes or cancellations must be requested within 2 hours of placing your order. After that window the order may already be in fulfillment and cannot be changed, but it remains covered by our 90-day money-back guarantee.
