What is the daily cutoff time for same-day shipping?

Orders placed before 12 pm EST on business days (Mon–Fri) ship the same day.

How to maximize your chances

• Place the order early and choose USPS Express if time-sensitive.
• Use a complete U.S. shipping address (company/lab + suite/unit).
• Ensure payment clears (ACH authorization, BTC confirmations).
• Watch your email in case we need a quick address or compliance verification.

Important notes

• You’ll receive tracking when we print the label; first scans can take several hours after pickup.
• We guarantee the dispatch window from our facility; carrier transit times are outside our control.

If you have a hard deadline, contact support right after checkout with your order number so we can prioritize when possible.
