Shipping Policy

We ship within the United States only. We do not currently ship internationally, and we do not facilitate international transshipment. Orders ship from our facility in the United States. We may decline or cancel orders to destinations we cannot lawfully or safely service.

Orders are processed Monday through Friday, excluding holidays. Orders placed before our same-day cutoff (currently 5:00 PM CT / 6:00 PM ET) on a business day are typically dispatched the same business day; orders placed after the cutoff, on weekends, or on holidays are processed the next business day. Cutoffs and handling times are estimates and may change during high volume.

Estimated delivery times begin once an order is dispatched and reflect carrier estimates, not guarantees. Current options and rates (subject to change; the exact charge is shown at checkout) include:

• Standard (USPS Priority): typically 3–5 business days.
• Express (USPS Priority): typically 1 business day.
• Average delivery for most orders is 2–3 business days, tracked.

Free shipping may be offered on qualifying orders over a stated threshold (currently $300, subject to change). The qualifying threshold and any promotional shipping offers are reflected at checkout.

Shipping insurance may be included or offered as a separate line item at checkout. Where insurance is purchased or included, eligible lost or damaged shipments are covered as described in our Returns & Refund Policy. Coverage terms and amounts are shown at checkout.

Orders are packaged appropriately for their contents, including insulated packaging for temperature-sensitive materials where applicable. You are responsible for promptly inspecting, properly storing, and handling products on receipt in accordance with our Research Use Only / Compliance & Safety Disclaimer and any provided documentation.

A tracking number is emailed when your package leaves our facility, and tracking and delivery updates may also be sent by SMS where you have provided your number and consented. Tracking information is provided by the carrier and may take time to update.

You are responsible for providing a complete and accurate shipping address. We are not responsible for delays or non-delivery caused by incorrect or incomplete addresses. Address changes may not be possible once an order is processed; contact [email protected] as early as possible.

• Carrier delays: delivery estimates are not guaranteed, and we are not responsible for delays once a package is in the carrier's possession.
• Damaged or incorrect items: if your order arrives damaged or you receive the wrong item, contact us promptly and we will ship a replacement at no charge as described in our Returns & Refund Policy.
• Lost or stolen: for shipments confirmed lost in transit or where insurance applies, contact us to arrange a replacement or other resolution. We may require reasonable documentation.

Except where shipping insurance applies or as otherwise required by law, risk of loss passes to you upon our delivery of the package to the carrier. Title passes upon full payment and dispatch.
