Free Shipping
All orders ship free of charge within the United States. No minimum order is required.
Processing Time
Chameleon fulfills orders 6 days per week, except Sunday. Orders placed before 2:00 PM Pacific usually ship the same day. Orders placed after the cutoff, on Sunday, or on postal/carrier holidays will usually process during the next available fulfillment window.
Delivery Timeframe
Most non-PO-box orders now ship by FedEx 2Day. PO Boxes ship by USPS Priority Mail, and exceptions may use another available service depending on address and order details. Tracking is emailed once your order ships. Carrier delivery dates are estimates and cannot be guaranteed.
Shipping Area
We currently ship to the United States only. We do not offer international shipping at this time.
Exterior Packaging
Product names and descriptions are not printed on exterior shipping materials. A small Chameleon sticker may appear; it does not identify the contents.
Carrier
Orders are shipped by UPS, USPS, or another major carrier at our discretion. Carrier selection is based on destination, order size, and reliable delivery speed.
Tracking
A tracking number will be emailed to you once your order ships. You can also check your order status by logging into your account on our site.
Delivery Issues
If your tracking shows delivery but you have not received your package, please:
- Check with household members and neighbors
- Check any secondary delivery locations, such as porch, mailbox, parcel locker, or building office
- Contact the carrier with your tracking number
- Contact Stuart at stuart@chameleonsciences.com if you need assistance
Address Accuracy
Please double-check your shipping address before completing your order. If you notice an address issue after ordering, contact Stuart as quickly as possible. We cannot guarantee changes after an order has entered fulfillment or been handed to the carrier.
Temperature-Sensitive Shipping
Lyophilized research materials are generally stable through normal domestic transit. For best handling after delivery, bring the package inside promptly and follow the storage guidance on the product page or batch documentation. Optional cold packaging may be available at checkout, but it is not temperature-controlled shipping and does not guarantee a specific arrival temperature.
