This Shipping Policy explains the order processing, shipping, delivery, and related practices of ESFIDELIS Biosciences ("ESFIDELIS," "we," "us," or "our").
Orders are subject to payment authorization, inventory availability, compliance review, and order verification before shipment.
Processing times may vary depending on order volume, weekends, holidays, inventory availability, payment verification, and other operational factors.
Available shipping methods and applicable shipping charges will be displayed during checkout when available. Shipping options may vary depending on the destination, order contents, carrier availability, and other operational considerations.
ESFIDELIS currently fulfills eligible orders to supported destinations within the United States. We reserve the right to restrict shipping to certain locations when required for legal, compliance, carrier, or operational reasons.
Customers are responsible for providing a complete and accurate shipping address at the time an order is placed.
Customers should contact ESFIDELIS as soon as possible if an address correction is required. We cannot guarantee that an address can be changed after an order has entered fulfillment or been transferred to the shipping carrier.
Any delivery timeframe provided by ESFIDELIS or a shipping carrier is an estimate unless expressly stated otherwise. Delivery times may be affected by carrier delays, weather, holidays, service disruptions, destination conditions, and other circumstances outside our reasonable control.
When tracking information is available, it may be provided to the customer after an order has been prepared for shipment.
Tracking information may require additional time to become active after a shipping label is created.
Customers should inspect their order promptly after delivery. If an order arrives damaged, contains an incorrect item, or is materially different from the order placed, please contact ESFIDELIS promptly through our Contact page.
We may request photographs of the package, shipping label, packaging materials, and affected product so that we can investigate the issue and determine an appropriate resolution.
If tracking information indicates that a shipment has been delayed, lost, or otherwise affected during transit, please contact ESFIDELIS so that we can review the shipment information and, where appropriate, coordinate with the carrier.
A carrier investigation or other verification may be required before a replacement or refund can be considered.
If carrier tracking shows a package as delivered but it cannot be located, customers should first check the delivery location, household or business recipients, nearby secure locations, and any delivery information provided by the carrier.
Customers may contact ESFIDELIS for assistance reviewing the available tracking information. Resolution of delivery disputes may depend on the results of carrier records or investigations.
Packages may be returned to ESFIDELIS because of an incorrect or incomplete address, unsuccessful delivery attempts, refusal of delivery, or other carrier-related circumstances.
If a shipment is returned to us, we will review the circumstances and contact the customer when additional information or action is required. Additional shipping charges may apply to reshipment when permitted by applicable law and appropriate under the circumstances.
Products designated as Research Use Only are shipped solely for their stated laboratory, analytical, or research purposes. Shipment of a product does not change its Research Use Only designation or intended use.
ESFIDELIS reserves the right to decline, hold, or cancel an order when reasonably necessary because of inventory limitations, payment concerns, suspected fraud, shipping restrictions, compliance requirements, or applicable law.
We may update this Shipping Policy to reflect changes in our fulfillment operations, shipping carriers, services, business practices, or legal requirements. The current version and its effective date will be published on this page.
Questions concerning an order, shipment, or this Shipping Policy may be directed to ESFIDELIS Biosciences through the information provided on our Contact page.
