Shipping Policy

Last updated: January 7, 2026

Shipping Policy

Fast fulfillment, clear tracking, and the right support option for your order.

Shipping method is determined automatically by the address entered at checkout. At Kirin Research, we work to process orders quickly, package them securely, and provide tracking updates so you can follow your shipment from pickup to delivery.

Processing Time

Orders are typically processed and shipped the next business day. Processing times exclude weekends and major holidays.

Shipping Carriers & Methods

  • Street address — Ships via FedEx 2 Day (P.O. Boxes not accepted).
  • P.O. Box — Ships via USPS Priority Mail (P.O. Boxes only).

Shipping method is automatically determined by the address entered at checkout.

Delivery Timeframes

  • FedEx 2 Day: Typically delivers within 2–4 business days after carrier pickup.
  • USPS Priority Mail: Typically delivers within 2–4 business days after carrier pickup.

Delivery times may vary during peak or holiday seasons based on carrier processing.

Package Protection & Delivery Issues

At checkout, customers may choose to add Kirin Package Protection. This protection applies only to qualifying shipping issues where a package is lost in transit, stolen in transit, or damaged upon arrival.

  • If protection is selected at checkout: qualifying in-transit loss, in-transit theft, and damage-on-arrival claims may be eligible for review and resolution.
  • If protection is not selected at checkout: the customer assumes responsibility for shipping risk once the order is placed and processed by the carrier.
  • Packages marked as delivered by the carrier are not considered lost in transit. Once a package has been delivered to the shipping address provided at checkout, including a mailbox, porch, doorstep, parcel locker, mailroom, or similar delivery location, Kirin Research is not responsible for loss, theft, or mishandling after delivery.
  • Protection must be selected during checkout and cannot be added after an order is placed.

Please note: Coverage is limited to qualifying in-transit issues and damage upon arrival. It does not extend to packages after confirmed delivery by the carrier.

Tracking & Updates

  • Tracking information is emailed automatically once your shipping label is created.
  • Tracking updates may not appear immediately and can lag until the carrier performs the first scan.
  • After handoff to FedEx or USPS, delivery timing and tracking updates are controlled by the carrier.
  • For tracking-related questions, please use our tracking page.

Address Accuracy

  • Please double-check your shipping address at checkout.
  • Street addresses cannot be shipped to P.O. Boxes.
  • Address modifications must be requested before shipment.
  • Once an order has shipped, we cannot make address changes.

U.S. Shipping Only

  • We currently ship to U.S. addresses only.
  • No international shipping, forwarding services, or reshippers.
  • Orders placed with non-U.S. destinations will be canceled and refunded.
