Shipping Policy

01Service Area

Crescent ships to all 50 U.S. states, Puerto Rico, Guam, and the U.S. Virgin Islands. We do not ship to:

• International addresses, including Canada and Mexico;
• American Samoa or the Northern Mariana Islands;
• APO, FPO, or DPO military addresses;
• P.O. boxes (a deliverable street address is required for all orders).

If your shipping address falls outside of our aforementioned service areas, your order will not be accepted at checkout.

02Processing Time

Orders placed before 12:00 PM Eastern Time on a business day typically ship the next business day. Orders placed after 12:00 PM ET, on weekends, or on U.S. federal holidays will ship within 1–2 business days.

Back-ordered items may have longer processing times; any extended timeline will be noted on the product page and at checkout. If your order will be delayed for any reason, we will contact you with options.

03Shipping Methods

All orders ship via USPS. The options shown at checkout depend on your order total:

• USPS Ground Advantage — $7.97. Estimated transit 2–5 business days from our New York origin.
• USPS Priority Mail — $12.98. Estimated transit 2–3 business days.
• Orders of $250 or more (after any discount) — Free. These ship via USPS Priority Mail at no charge; the paid options are not shown once free shipping applies.

For most destinations in the contiguous 48 states, Ground Advantage and Priority Mail arrive within a similar window and Ground is the more economical choice under $250. Priority Mail may deliver noticeably faster to more distant destinations, including CA, WA, OR, NV, ID, AK, HI, PR, GU, and VI. USPS transit-time estimates are not guaranteed and can vary with distance from origin, weather, and carrier operational load.

05Shipping Costs

Orders under $250 (after any discount): USPS Ground Advantage $7.97, or USPS Priority Mail $12.98. Each rate includes carrier charges, packaging materials, tracking, and lot-traceable documentation at no additional cost.

Orders of $250 or more (after any discount): USPS Priority Mail ships free. Once free shipping applies, the paid options are hidden at checkout so you are always shown the free method. See §03 for expected transit windows.

06Tracking

You will receive an email with carrier tracking information when your order ships. Tracking information is updated by the carrier and may take up to 24 hours to appear after dispatch. Customers with accounts may also view tracking on their order-history page.

07Address Accuracy

You are responsible for providing a complete, accurate, and deliverable shipping address.

• Crescent is not responsible for orders shipped to incorrect or undeliverable addresses provided by the customer.
• Address changes after order placement are not guaranteed and depend on the order's processing status. Contact [email protected] as soon as possible if you need to change an address.
• Re-shipment of orders returned to us due to incorrect addressing requires the customer to pay additional shipping fees.

08Delivery Issues

If you experience a delivery issue, contact [email protected] as soon as possible. Common scenarios:

Lost in Transit

If carrier tracking shows no movement for more than five (5) business days, contact us. We will open an investigation with the carrier and arrange a replacement once the carrier confirms loss.

Marked Delivered, Not Received

Contact us within 48 hours of the carrier-marked delivery date. We will work with the carrier to investigate and resolve.

Damaged on Arrival

See the Returns Policy for the damaged-on-arrival replacement procedure. Report damage within 48 hours and provide photo evidence.

Significantly Delayed

If your order is more than five (5) business days past the estimated delivery date, contact us; we will investigate and provide options.

09Signature Requirements

The following shipments may require signature confirmation at delivery:

• Orders of $250 or more;
• Shipments to addresses with prior delivery issues.

Signature requirements are noted at checkout where applicable. If signature delivery is required and the package cannot be delivered, the carrier will hold the package for pickup or attempt re-delivery per its standard policy.

10Carrier Delays & Force Majeure

Crescent is not responsible for delays caused by carriers, weather events, natural disasters, customs (where applicable), labor actions, public-health emergencies, or other circumstances outside our reasonable control. Estimated delivery times are not guaranteed and represent typical carrier transit windows under normal conditions.

11Restricted Destinations

Crescent reserves the right to refuse to ship to any destination where local, state, or federal law restricts the importation, possession, or use of research-grade reagents/compounds. Crescent also reserves the right to refuse shipment for any reason in its sole discretion. If your order cannot be shipped, you will be notified and refunded in full to the original payment method.
