Shipping Policy

Orders are typically processed within 1-2 business days of successful payment confirmation. Business days are Monday through Friday, excluding U.S. federal holidays. Orders placed after the daily order cutoff of 1:00 PM (facility local time) are processed the following business day. During periods of high order volume or when additional identity or institutional verification is required, processing may take longer; we will notify you by email if a delay is expected.

Certain orders, particularly first-time or high-volume institutional orders, may be held briefly for manual review to confirm shipping address accuracy and compliance with destination restrictions before the order is released to a carrier. This review does not indicate any issue with your account and is a routine quality-control step.

We ship via nationally recognized carriers, selected based on destination, package requirements, and service level chosen at checkout. Estimated delivery windows are provided at checkout and in your shipping confirmation email; these are estimates provided by the carrier and are not guaranteed delivery dates. Typical domestic transit time is 2-5 business days after dispatch.

Many research compounds we supply are temperature- and light-sensitive. Applicable orders are packed with insulated packaging, and where appropriate, gel packs or other temperature-stabilizing materials, along with light-protective outer packaging, to help preserve compound stability in transit. Upon receipt, researchers should immediately transfer materials to the storage conditions specified on the product's Certificate of Analysis and product page.

If a temperature-sensitive shipment appears to have been compromised in transit (e.g., packaging failure, extreme delay, or visible damage to protective materials), please contact research support within 48 hours of delivery so we can evaluate the shipment and, where warranted, arrange a replacement.

We ship to addresses within the United States, excluding any jurisdictions where sale or importation of research compounds is restricted or prohibited by applicable law. It is the buyer's responsibility to confirm that receipt of research materials is permitted at the destination address under state and local law and any applicable institutional policy.

We ship to a limited number of international destinations, subject to import regulations governing research chemicals and laboratory materials in the destination country. Available destinations are shown at checkout. International orders may be subject to customs inspection, import duties, and taxes assessed by the destination country; these charges are the responsibility of the recipient and are not included in our shipping charges. We are not responsible for delays caused by customs processing.

Once your order ships, you will receive a shipping confirmation email containing carrier and tracking information. Tracking information is also available from your account dashboard under Order History for registered customers.

Shipping charges are calculated at checkout based on package weight, destination, and selected service level, and are displayed prior to payment. Orders meeting the free-shipping subtotal threshold displayed at checkout qualify for complimentary standard shipping within the domestic service area.

If tracking indicates a shipment is significantly delayed or shows no movement for an extended period, please contact research support with your order number so we can investigate with the carrier. Claims for packages marked as delivered by the carrier but not received should be reported within 7 days of the marked delivery date.

We may update this Shipping Policy from time to time to reflect changes in carriers, packaging methods, or applicable regulations. The version posted on this page at the time an order is placed governs that order.
