Shipping Policy

PFPEP LLC | www.pfpep.com
Effective date: September 27, 2026 · Last updated: September 27, 2026

This Policy explains processing time, transit estimates, packaging, tracking, and limits on delivery. It is part of our Terms and Conditions and should be read with our Refund Policy and Privacy Policy. All products are sold for laboratory and in-vitro research use only. 

1. Order processing

Allow 24 hours after an order is placed for processing. Orders placed on a business day generally enter fulfillment within 24 hours. Orders placed on Saturday, Sunday, or a U.S. federal holiday are processed the next business day. The 24-hour processing window begins then. We may need extra time if an address fails validation, payment is under review, or an item is temporarily unavailable. We will contact the email on the order if that happens. Processing time is separate from carrier transit time. 

2. FedEx Ground Shipping

FedEx Ground shipping is 3–5 business days after the order ships, not after the order is placed. A typical domestic timeline is processing up to 24 hours, then FedEx Ground transit of 3–5 business days after the carrier scan. Business days are Monday through Friday, excluding U.S. federal holidays. Weekends in transit do not count toward the 3–5 business-day estimate. These times are estimates, not guarantees. Weather, carrier volume, remote ZIP codes, incorrect addresses, and inspection can add delay.

Shipping Rates: Orders totaling $250 or more qualify for free shipping. Orders under $250 are charged a flat shipping fee of $15.

3. Where we ship

We currently focus on shipping within the United States. If an order cannot be delivered to the address provided, we may cancel it and follow our Refund Policy. You are responsible for entering a complete, deliverable address. We are not responsible for delay or loss caused by a missing suite number, wrong ZIP code, or a destination that cannot accept the package. 

4. Packaging

Orders are packed to protect vials in transit. Packaging is intended to be plain and professional. We do not print product names on the outside of the carton when the carrier label allows a generic ship-from name. Lyophilized research materials are typically shipped by ground under ordinary parcel conditions. 

5. Tracking

When the carrier accepts the package, we send tracking to the email used at checkout. Delivery status after that scan is controlled by the carrier. Please check tracking before contacting support. If tracking shows delivered and you cannot locate the package, check with others at the address and with the carrier first. Confirmed carrier loss or damage is handled under our Refund Policy. 

6. Delivery attempts and undeliverable packages

If the carrier cannot complete delivery because of an access problem, refused shipment, expired hold, or incorrect address, extra fees or return-to-sender costs may apply. Reshipment is not automatic. We are not required to refund carrier charges on a package returned as undeliverable because of customer address error. 

7. Delays we do not control

We are not liable for late arrival caused by the carrier after the first scan; weather, natural events, or peak-season congestion; incorrect or incomplete address information; recipient unavailable for delivery; or inspection, seizure, or refusal by a third party. If a package is still unmoved for an unusual period after shipment, email support@pfpep.com with the order number and tracking number. 

8. Order changes

Address or shipping changes must be requested before the order leaves processing. After the 24-hour processing window, the label may already be created and cannot be changed. 

9. International and restricted destinations

Unless the Site expressly offers another option at checkout, we do not guarantee international delivery. You are responsible for knowing whether your destination can legally receive research materials.
