Thank you for choosing NexaStars (operated under APAC). Below is our complete shipping and delivery policy, detailing fulfillment processing times, available carrier speeds, package tracking procedures, and guidelines to ensure a smooth, secure, and reliable shipping experience for your research compounds.
1. Shipping Rates & Carrier Options (US Domestic)
Currently, nexastars.net fulfills domestic shipments across the United States with standard and expedited carrier options:
| Shipping Method | Estimated Transit Time | Shipping Cost |
| FedEx 2-Day Air | 2 Business Days | $25.00 |
| FedEx Express Saver (3-Day) | 3 Business Days | FREE |
| USPS Priority Mail (P.O. Boxes Only) | 2 – 3 Business Days | FREE |
| UPS Next Day Air (Florida Destination Only) | Next Business Day* | FREE |
Transit speeds refer strictly to the timeframe after the carrier takes physical custody of the package.
Florida Address Special: Orders placed before 1:00 PM (EST) Monday through Friday are typically delivered on the next business day. Orders placed on weekends will arrive on Tuesday (not Monday).
2. Order Processing & Handling Time
All orders are processed Monday through Friday, excluding official federal holidays.
Standard fulfillment and packaging usually take 24 to 72 business hours.
Orders placed before 1:00 PM (EST) on regular business days receive priority dispatch processing.
During high-volume periods (promotional sales or batch releases), handling times may be slightly extended.
3. Package Tracking Infrastructure
Once your order is packed and handed over to the courier, an automated confirmation email containing a tracking number will be dispatched to your registered address (sent via info@nexastarsllc.com). Please allow a few hours for carrier systems to register and update initial transit status.
You can track your packages directly using the carrier portals below:
FedEx Tracking Portal: https://www.fedex.com/fedextrack
UPS Tracking Portal: https://www.ups.com/track
USPS Tracking Portal: https://tools.usps.com/go/TrackConfirmAction_input
4. Shipping Delays & Carrier Issues
NexaStars is not liable for logistics delays caused by:
Carrier operational backlogs or technical disruptions
Severe weather conditions and natural force majeure events
Incorrect, unlocatable, or incomplete shipping addresses provided during checkout
Regional postal service disruptions
If your shipment experiences unusual tracking anomalies, extended delays, or appears lost, please contact us immediately so we can open a trace investigation with the carrier on your behalf.
5. Packages Marked as "Delivered" But Not Received
If the carrier tracking portal status displays "Delivered" but you cannot locate your package:
Inspect surrounding areas around your premises (porch, mailbox, side entry, garage, etc.).
Check with household members, building managers, or adjacent neighbors.
Verify your exact shipping address on your order confirmation email.
If you still cannot locate the parcel, contact us within 48 hours. Our support team will initiate an official delivery investigation with the carrier. Once the carrier completes its investigation and renders a final verdict, we will guide you through the appropriate resolution steps. Please note that NexaStars cannot issue replacements or store credits until the carrier investigation is formally closed.
6. Incorrect or Incomplete Shipping Addresses
It is the sole responsibility of the customer to ensure that the delivery address entered during checkout is complete and accurate (including apartment, suite, or unit numbers).
NexaStars is not responsible for lost or misdelivered packages caused by inaccurate addresses provided by the client.
Address modifications can only be made before the package enters the processing and fulfillment queue.
Once an order has been fulfilled or assigned a tracking code, no address modifications can be processed.
7. Undeliverable & Returned Packages
Packages returned to our administrative warehouse due to:
Incorrect or invalid street addresses
Missing unit/suite numbers
Multiple failed delivery attempts by the carrier
...may be subject to re-shipment fees at the purchaser's expense.
8. Shipping Restrictions & P.O. Boxes
P.O. Box Deliveries: P.O. Box addresses are shipped exclusively via USPS Priority Mail (FedEx and UPS do not deliver to P.O. Boxes).
Military Addresses: We currently do not ship to APO/FPO military addresses.
9. Damaged Shipments & Claim Filing
If your order arrives physically damaged, please contact us within 48 hours of delivery at info@nexastarsllc.com with the following required details:
High-resolution photos of the outer shipping box.
High-resolution photos of the inner damaged product/vials.
Your Order Number.
