At Zenith Bioscience LLC, we are committed to delivering your research products safely, securely, and efficiently. This policy outlines our shipping procedures, delivery timeframes, costs, and important information about receiving your order.

1. Shipping Coverage and Restrictions

Domestic Shipping Only: We ship to all 50 U.S. states, Washington D.C., Puerto Rico, and the U.S. Virgin Islands. We do not ship to APO/FPO addresses or international destinations at this time.

Territory Restrictions: Shipments to Puerto Rico (PR) and the U.S. Virgin Islands (VI) are limited to USPS service only.

Origin: All orders are shipped from our secure facility in Aurora, Colorado (80013).

Restricted Locations: We cannot ship to P.O. boxes. A physical street address is required for all deliveries.

2. Shipping Methods and Service Levels

Available Carriers and Services: During checkout, you may choose from the following shipping options (subject to availability based on destination):

  • USPS Priority Mail — Est. 2-3 business days
  • UPS Ground — Est. 1-5 business days
  • UPS 2nd Day Air — Est. 2 business days
  • UPS Next Day Air Saver — Next business day by 3:00 PM
  • FedEx Ground — Est. 1-5 business days
  • FedEx 2Day — Est. 2 business days
  • FedEx Standard Overnight — Next business day by 4:30 PM

All shipments include real-time tracking information. Delivery timeframes are estimates and may vary based on origin, destination, weather, and carrier capacity.

Saturday Delivery: For UPS 2nd Day Air, UPS Next Day Air, and FedEx 2Day, a Saturday Delivery option is available at checkout when a Saturday delivery is reachable for your address, labeled with the Saturday date it will arrive. Selecting it delivers your package on a Saturday instead of the next available weekday, for an additional surcharge shown at checkout. See Section 4 for how the surcharge is calculated.

3. Processing and Handling Time

Same-Day Shipping Cutoffs: Orders placed and confirmed before the following cutoff times typically ship the same day:

  • Monday–Friday: 3:00 PM Mountain Time
  • Saturday–Sunday: 12:00 PM Mountain Time

Orders placed after these cutoffs will be processed and shipped the following day.

Extended Processing: Processing time may be extended during:

  • High-volume periods
  • Federal holidays
  • Inventory restocking periods
  • Order verification requirements

Notification: You will receive email confirmation once your order has been processed and shipped. See Section 8 for tracking details.

4. Shipping Costs and Free Shipping

Dynamic Rates: Shipping rates are calculated in real-time during checkout based on your destination, selected carrier, and service level. Rates are displayed before you complete your order.

Free Shipping Threshold: Orders over $200 (after discounts, before taxes) qualify for free shipping on ground and 2-day services (USPS Priority, UPS Ground, UPS 2nd Day Air, FedEx Ground, FedEx 2Day).

Overnight Discount: Overnight services (UPS Next Day Air Saver, FedEx Standard Overnight) receive a $15 discount on orders over $200 instead of free shipping.

Saturday Delivery Surcharge: Choosing Saturday Delivery on UPS 2nd Day Air, UPS Next Day Air, or FedEx 2Day adds a surcharge on top of that service’s regular cost. The surcharge applies in addition to the standard rate for the service — it is calculated after any free-shipping or overnight-discount benefit the order already qualifies for, so a Saturday delivery order never costs less than the surcharge itself, even on orders over $200. The exact surcharge amount is shown at checkout before you complete your order and varies by destination and carrier.

5. Delivery Timeframes and Expectations

Estimated Delivery: Delivery estimates are shown at checkout based on your selected shipping method and destination.

Remote Areas: Delivery to remote or rural areas may require additional time beyond the standard estimate.

Business Days: Monday through Friday, excluding federal holidays. Weekend and holiday deliveries are not available except for orders where Saturday Delivery was selected at checkout (see Section 2) — all other services deliver on business days only.

No Guarantee: Delivery timeframes are estimates only. Zenith Bioscience does not guarantee delivery dates and is not liable for carrier delays.

6. Delivery Process

Standard Delivery: Packages are delivered to the address provided during checkout.

Delivery Attempts: If delivery is unsuccessful:

  • The carrier will attempt delivery up to 3 times
  • Package will be held at the local carrier facility for pickup
  • Pickup requires valid photo ID matching shipping address
  • Packages held for 5 business days before return to sender

7. Special Handling for Research Products

Temperature-Sensitive Items: Products requiring temperature control are shipped with:

  • Insulated packaging materials
  • Temperature monitoring indicators
  • Expedited processing to minimize transit time

Packaging Standards: All products are packaged according to research industry standards with appropriate labeling and documentation.

9. Address Accuracy and Changes

Customer Responsibility: Please ensure your shipping address is accurate and complete. We are not responsible for delays, losses, or additional fees resulting from incomplete or inaccurate address information.

Address Changes: Address modifications may not be possible once an order has been processed. Contact us immediately if changes are needed.

10. Shipping Issues and Liability

With Shipping Protection: If you purchased shipping protection at checkout, file a claim for lost or damaged packages from your account. See Section 12 for full details on coverage and the claims process.

Without Shipping Protection: Zenith Bioscience is not responsible for lost, stolen, or damaged packages once they leave our facility. We will not file claims or issue replacements for unprotected orders.

Address Errors: We are not responsible for packages delivered to incorrect addresses due to customer-provided information, regardless of shipping protection status.

11. Holiday and Weather Delays

Holiday Schedule: No processing or shipping on federal holidays. Orders placed on holidays will be processed the next business day.

Weather Delays: Severe weather conditions may cause shipping delays beyond our control. We will notify customers of significant delays.

12. Shipping Protection

Zenith Bioscience offers optional shipping protection at checkout, calculated as 4% of your order subtotal. This coverage protects against lost and damaged packages.

What’s Covered:

  • Lost Packages: Carrier has not delivered the package within 7 business days of the estimated delivery date.
  • Damaged Packages: Product(s) broken, leaking, or compromised on arrival.

Filing a Claim: Go to your account’s claims page and select an order to file a claim. You’ll be asked for a description of the issue and photos (for damage claims) — no need to email us. Most claims are processed within 24-48 hours and are reviewed in-house by our support team for fast resolution.

Important: If shipping protection is not selected at checkout, Zenith Bioscience is not responsible for lost or damaged packages once they leave our facility.
