Shipping Policy

This Shipping Policy explains how Davinci Research Institute processes, packages, tracks, and ships research-use orders within the United States.

Last updated: August 4, 2026

1. Where We Ship

Davinci Research Institute currently ships within the United States only, including all 50 states and the District of Columbia.

We do not currently ship to:

• International addresses;
• U.S. military APO, FPO, or DPO addresses;
• U.S. territories outside the 50 states, including Puerto Rico, Guam, the U.S. Virgin Islands, and similar locations;
• Freight-forwarding companies or package-reshipping services;
• P.O. boxes when the selected shipping carrier requires a physical street address.

If an order is submitted with an unsupported shipping destination, we may contact the customer to request a valid address. If a supported address cannot be provided before fulfillment begins, the order may be canceled and refunded to the original payment method.

2. Order Processing

Orders placed before 12:00 p.m. Eastern Time on a business day may be processed and shipped the same day. Business days are Monday through Friday, excluding U.S. federal holidays.

Orders placed after the daily cutoff, on weekends, or on holidays will generally be processed on the next business day. Davinci Research Institute does not normally process or ship orders on Saturdays, Sundays, or federal holidays.

Processing times may be extended during product launches, promotional events, high-volume periods, payment reviews, inventory verification, severe weather, or other operational disruptions.

3. Shipping Methods and Transit Times

Orders may be shipped using tracked carriers such as USPS, UPS, FedEx, or another appropriate shipping provider.

Carrier and service level may be determined based on the destination, shipment weight, package dimensions, service availability, and shipping method selected during checkout.

Transit estimates begin after the shipping carrier accepts the package. They do not include order-processing time and should not be considered guaranteed delivery dates.

4. Tracking Information

Tracking information will generally be sent to the email address associated with the order when a shipping label is generated.

An additional notification may be provided when the package is accepted or scanned by the carrier.

Tracking information may take several hours to update after label creation. A label-created status does not necessarily indicate that the carrier has physically received or scanned the shipment.

Customers are responsible for monitoring shipment tracking and ensuring that someone is available to receive the package where necessary.

5. Shipping Rates

Davinci Research Institute provides free standard shipping on qualifying orders of $200 or more.

The free-shipping option is applied automatically during checkout when the qualifying order subtotal is reached.

Orders below the free-shipping threshold are charged a flat shipping rate of $8.95 per order.

Taxes, shipping charges, discounts, and other applicable amounts will be calculated and displayed during checkout before the order is submitted.

6. Packaging

Orders are shipped using discreet outer packaging. External shipping materials are not intended to display prominent Davinci Research Institute branding, product imagery, or detailed descriptions of package contents.

Products are secured using appropriate protective materials designed to reduce movement and physical damage during standard transit.

Packaging methods may vary depending on product quantity, package dimensions, selected shipping service, and destination.

7. Product Stability and Temperature Handling

Lyophilized research-use compounds are generally packaged for standard transit conditions.

Davinci Research Institute does not currently provide guaranteed refrigerated or validated cold-chain shipping as part of its standard shipping service.

Customers whose laboratory protocol requires refrigerated transit, overnight delivery, validated temperature monitoring, or specialized packaging should contact YOUR-SUPPORT-EMAIL before placing an order.

Specialized handling requests are subject to availability, additional charges, carrier limitations, and written approval before checkout.

8. Incorrect or Incomplete Shipping Addresses

Customers are responsible for providing a complete and accurate shipping address during checkout.

This includes the recipient name, street address, apartment or suite number, city, state, ZIP code, email address, and telephone number.

Davinci Research Institute is not responsible for delays, unsuccessful delivery attempts, returned shipments, or losses resulting from incorrect, incomplete, outdated, or undeliverable customer information.

To request an address correction, contact YOUR-SUPPORT-EMAIL immediately and include your order number and corrected address.

Address changes cannot be guaranteed once an order has entered processing or a shipping label has been generated.

9. Carrier Delays

After a package has been transferred to a shipping carrier, delivery timing is controlled by that carrier.

Davinci Research Institute is not responsible for delays resulting from weather, transportation disruptions, carrier backlogs, service interruptions, routing issues, natural disasters, government actions, or other circumstances outside our reasonable control.

Shipping delays do not automatically qualify an order for cancellation, replacement, account credit, or refund after the package has left our facility.

10. Lost Packages

A shipment may be considered potentially lost when tracking information has shown no meaningful movement for at least seven business days following carrier acceptance.

To report a potentially lost package, contact YOUR-SUPPORT-EMAIL and provide:

• Your full name;
• Your order number;
• The shipment tracking number;
• A clear description of the issue;
• Any relevant communications received from the shipping carrier.

Davinci Research Institute may assist with initiating or reviewing a carrier investigation. Assistance with an investigation does not guarantee replacement, reshipment, account credit, or refund.

11. Damaged Packages

If a shipment arrives visibly damaged, contact YOUR-SUPPORT-EMAIL within 72 hours of delivery.

Include clear photographs of:

• The exterior shipping package;
• The shipping label;
• The internal packaging;
• The affected product or products;
• Any visible leakage, breakage, crushing, or other damage.

Keep all packaging materials and affected products until the claim has been reviewed. Claims submitted without sufficient supporting documentation may be denied.

12. Delivered but Missing Packages

If tracking indicates that a package was delivered but it cannot be located, customers should first:

• Check the delivery location, mailbox, porch, reception area, parcel locker, or other secure delivery location;
• Ask household members, employees, neighbors, building management, or reception staff whether they accepted the package;
• Contact the shipping carrier to request available delivery details or geographic scan information;
• Allow up to 24 hours because some packages may be marked delivered shortly before physical delivery.

Davinci Research Institute is not responsible for theft, loss, or misplacement after a successful carrier delivery scan. Where reasonably possible, we may review available information and assist with a carrier inquiry.

13. Returned-to-Sender Packages

Packages may be returned to Davinci Research Institute because of an incorrect address, refused delivery, unsuccessful delivery attempts, an unclaimed shipment, carrier restrictions, or another delivery issue.

If a package is returned to us, we will review the circumstances and contact the customer when appropriate. Additional shipping charges may be required before reshipment.

Original shipping fees and carrier return charges may be non-refundable, subject to applicable law and the specific circumstances of the shipment.

14. Bulk and Institutional Orders

For orders containing 25 or more vials of a single compound, or for shipments intended for academic, biotechnology, analytical, or contract-research laboratories, contact YOUR-SUPPORT-EMAIL before placing an order.

Volume pricing, institutional invoicing, consolidated shipping, payment terms, or specialized fulfillment arrangements may be available subject to approval.
