AEY Labs ships from our overseas fulfillment center directly to customers in the United States. This page explains our rates, processing time, delivery expectations, and what to expect from tracking during transit.
Shipping rates
Shipping costs are based on the size of your order:
- Orders of 1–9 kits: $60 flat rate
- Orders of 10 or more kits: $90 flat rate
- Orders over $2,500: free shipping
Rates are shown at checkout based on your cart contents.
Where we ship
AEY Labs ships to the United States only. We do not ship to any other country at this time. Orders placed with non-US shipping addresses will be cancelled and refunded.
Order processing
After you complete payment, your order moves from Pending Payment to Processing. From this point, please allow 1–3 business days for your order to be packed, dispatched, and assigned a tracking number. You will receive an email with your tracking number as soon as your order ships.
If you have not received a tracking number after 3 business days, email support@aeylabs.org with your order number and we’ll look into it.
Delivery time
Estimated delivery time is 10–15 business days from the date of dispatch. Some shipments arrive faster, some take a few days longer depending on customs processing and carrier conditions at the time of shipment.
These estimates are not guaranteed.
Where to track your package
Your tracking number works on multiple tracking sites, and which one to use depends on where your package is in its journey:
- ParcelsApp — Best for the full journey. Tracks the package from China through US customs and into final delivery. This is the recommended site to use throughout transit.
- 17Track — Another reliable multi-carrier tracker that works well for the China-to-US leg. A good alternative if ParcelsApp isn’t showing updates.
- FedEx Tracking — Use this only once your package has arrived in the United States. FedEx will not show any updates on your tracking number until they physically receive the package in the US, which typically happens around Day 10–14 of transit. Checking FedEx earlier will return no results — this does not mean your package is lost.
What to expect from your tracking number
This is the most important thing to know about international shipping from China to the US: your tracking number will often appear “stuck” or show no updates for several days at a time. This is completely normal and does not mean your package is lost.
Here’s the typical pattern you’ll see:
- Day 1–2 after dispatch: Tracking shows the package was received by the origin carrier. You may see one or two early scans on ParcelsApp or 17Track.
- Day 3–7: Tracking often goes silent during this period as the package moves through the domestic Chinese carrier network and prepares for international export. Don’t be alarmed if you see no updates for 3–5 days here.
- Day 7–10: You should see “Departed origin country” or a similar update once the package leaves China and enters international transit.
- Day 10–14: US customs clearance and handoff to FedEx. This is when FedEx tracking will start showing updates for the first time. This is also the second common quiet period — packages can sit in customs for several days while being processed.
- Day 14–15+: Once cleared, FedEx handles final delivery, and you’ll see rapid updates as it moves toward your address.
If your tracking has shown no updates for more than 7 consecutive days, email us at support@aeylabs.org with your order number and we’ll investigate.
About US customs
Most orders clear US customs without any issue. In rare cases, customs may request additional information or hold a package for inspection. US customs typically clears research compounds quickly when documentation is in order.
Address accuracy
You are responsible for providing an accurate and complete US shipping address at checkout. AEY Labs is not responsible for packages delivered to incorrect addresses provided by the customer, or for additional costs incurred resending packages returned due to invalid addresses.
If you need to correct an address after placing an order, email support@aeylabs.org immediately. We will make every reasonable effort to update the address if the order has not yet shipped, but cannot guarantee changes once the order has been dispatched.
Reshipment guarantee
If your shipment is genuinely lost in transit or fails to arrive within a reasonable window beyond our delivery estimate, AEY Labs will reship your order free of charge. Email support@aeylabs.org with your order number to start a reshipment claim.
This guarantee applies to genuine non-delivery situations. It does not apply to:
- Delays caused by inaccurate or incomplete addresses provided at checkout
- Packages refused at delivery or by customs
- Packages held at the destination for customer pickup that are not retrieved within the carrier’s holding window
- Delays caused by US customs processing while the package is still in transit
- Tracking gaps within the normal expected pattern described above
Damaged shipments
If your order arrives damaged — broken vials, compromised packaging, or visible defects — contact us at support@aeylabs.org within 48 hours of delivery with photos of the damage and packaging.
