From checkout
to delivery.

Processing and delivery estimates

Orders are usually processed within one to two business days after payment is confirmed. Weekends and holidays are excluded. Processing time is separate from carrier transit time, and high order volume, supply issues, payment or address questions, and compliance review can add time.

Where available, typical domestic transit estimates are two to five business days for standard shipping, one to three for expedited shipping, and one business day for overnight shipping. These are estimates, not guaranteed delivery dates. The choices offered for your address appear at checkout.

Rates, destinations, and order review

Shipping charges are calculated and shown before checkout is completed. CaliLean ships to accepted addresses within the United States and may limit destinations, carriers, or delivery methods for legal, payment, fraud, compliance, or operational reasons.

An order may be held, limited, or canceled before shipment if its payment, address, eligibility, or intended use requires review. The shop may use shipping and fulfillment providers, including ShipStation, and third-party carriers.

Your address and tracking

Provide a complete, accurate, deliverable address. A requested change may be possible before processing, but is not guaranteed once an order is packed or a label exists. An incorrect or inaccessible address can lead to delay, return, or additional reshipping costs.

A shipping confirmation should include tracking after dispatch. A newly created label can appear before the carrier scans the parcel; updates may take 24 to 48 hours to show. Some orders may require a signature, adult signature, identification, pickup, or other verification.

Missing or damaged packages

If tracking marks a parcel delivered but you cannot locate it, check the delivery location, mailroom, parcel locker, building staff, neighbors, and carrier notes first. CaliLean’s published policy treats carrier-confirmed delivery to the checkout address as delivery and does not automatically replace a package missing afterward.

For a stalled shipment, contact support@calilean.com with your order and tracking numbers. Report transit damage within seven days of delivery. Include clear photos of the outer box, label, internal packing, products, and visible damage. CaliLean reviews the record before deciding whether a replacement, credit, or refund is available.
