Shipping & Returns

Order Processing

Orders are typically processed and prepared for shipment by the next business day after payment has been received and the order has been accepted.

Processing may take longer during weekends, holidays, periods of high order volume, inventory delays, or other circumstances outside our reasonable control.

Shipping Charges

Standard shipping within the United States is $15.00. Orders totaling $250.00 or more qualify for free standard shipping.

Shipping charges and available shipping methods are displayed during checkout before an order is submitted. At this time, shipping is available to United States destinations only.

Delivery Estimates

We use shipping services with delivery speeds comparable to USPS Priority Mail or faster when available. Typical carrier transit time is approximately 2–3 business days after shipment.

Delivery dates and transit times are estimates and are not guaranteed. Weather, holidays, carrier service interruptions, transportation issues, or other circumstances outside the control of Cornhusker Biosupply may cause delays.

Tracking Information

When tracking information is available, it may be provided after an order has been prepared for shipment.

Tracking updates are provided by the shipping carrier and may take time to appear after a shipping label has been created.

Shipping Address

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

If you discover an address error, contact us as soon as possible. We cannot guarantee that an address can be changed after an order has entered processing or has been transferred to the carrier.

Lost or Delayed Packages

If tracking indicates that a package is delayed or has not arrived within the expected delivery window, please contact us so the available shipping information can be reviewed.

Carrier investigations, claims, and resolution times may vary depending on the circumstances and shipping service used.

Packages Marked Delivered

If tracking shows a package as delivered but you cannot locate it, first check the delivery area, mailbox, household members, neighbors, or other locations where the carrier may have left the shipment.

You may also need to contact the shipping carrier for additional delivery information.

Damaged or Incorrect Orders

If your order arrives damaged or you receive an incorrect item, contact Cornhusker Biosupply as soon as reasonably possible after delivery.

Please retain the product, packaging, shipping materials, and shipping label. Photographs may be requested so we can evaluate the issue and determine an appropriate resolution.

Returns

Due to product-integrity, storage, handling, and chain-of-custody considerations associated with research materials, Cornhusker Biosupply does not accept standard product returns after an order has been shipped.

Products should not be returned or mailed back unless Cornhusker Biosupply has specifically provided return instructions in connection with an approved order-resolution request.

Refunds & Replacements

Eligibility for a refund, replacement, store credit, or other resolution depends on the circumstances of the order and is governed by our Refund & Returns Policy.

Returned or Undeliverable Packages

Packages may be returned to sender because of an incorrect or incomplete address, refusal of delivery, carrier restrictions, or unsuccessful delivery attempts.

Additional shipping charges may apply if an order must be reshipped because of incorrect customer-provided shipping information or another issue outside our control.
