Shipping policy

Last updated: October 19, 2026

Service Associates International, LLC (dba Service AI) ships laboratory instruments, spare parts, and accessories from Southern California to customers in the United States and in many countries worldwide. Every item is packed with care to arrive safely and ready to perform.

1. Order Processing

Spare parts, accessories, and other smaller items usually ship within 2 business days after payment is received, excluding weekends and U.S. holidays.

Large instruments, such as centrifuges, ultracentrifuges, and mass spectrometers, require at least 2 weeks before shipping to allow for final testing, certification, crating, and freight arrangements. We will confirm the expected ship date with you when you order.

If we cannot ship your order within 30 days of payment, we will notify you and offer you the choice of waiting or receiving a full refund.

2. Shipping Within the United States

For smaller orders weighing up to 10 lb, we offer the following flat-rate options at checkout:

• Economy: $35
• Standard: $45
• Express: $75

Depending on your order, you may also see carrier-calculated rates for USPS Priority Mail, UPS 3 Day Select, and FedEx 2Day. The options and prices available for your order are shown at checkout before you pay.

3. International Shipping

We usually ship international orders with FedEx International services. Rates are calculated at checkout based on your destination and the weight and size of your order. If your country is not available at checkout, or you would like a different service, please contact us for a quote.

International orders may be subject to customs duties, import taxes, brokerage fees, and import permits or approvals, which are the buyer's responsibility and are not included in our prices or shipping charges. Customs clearance can delay delivery, and we are not responsible for delays caused by customs authorities. We comply with U.S. export control and sanctions laws and may decline or cancel any order that we cannot lawfully ship.

4. Large Instruments and Freight

Large or heavy instruments, such as centrifuges and ultracentrifuges, may require freight shipping, crating, or special handling. For these items, we will contact you with a shipping quote before your order ships, or you can request a quote before ordering. Freight deliveries may require a loading dock or liftgate service and someone available to receive the shipment. Professional installation is available separately; please contact us for details.

Freight quotes are prepared for your specific delivery address and will itemize the costs that apply to your shipment, which may include crating, liftgate service, inside delivery, and shipping insurance. Please let us know about any delivery restrictions at your site, such as stairs, narrow doorways, elevator size limits, or the lack of a loading dock, so we can plan the right delivery method.

5. Delivery Times

Delivery times shown at checkout are carrier estimates that begin once your order ships, and they are not guaranteed. We are not responsible for delays caused by carriers, weather, customs, or other events outside our control.

6. Tracking

When your order ships, we will email you a shipping confirmation with tracking information.

7. Shipping Addresses

Please make sure your shipping address is complete and correct. UPS, FedEx, and DHL cannot deliver to P.O. boxes, so please provide a street address for those services. If a package is returned to us because of an incorrect or incomplete address or a refused delivery, you may be responsible for the cost of reshipping.

8. Inspecting Your Delivery and Shipping Damage

Please inspect your shipment as soon as it arrives. If the package or product is damaged, note the damage with the carrier if possible, keep all packaging, and contact us with photos within 2 business days of delivery, as described in our Refund Policy. Risk of loss passes to you when the product is delivered to the carrier, as described in our Terms of Service, but we will work with you and the carrier on any damage reported on time.

9. Lost Packages

If your tracking shows no progress for an extended period or your package is marked delivered but you have not received it, please contact us and we will help you work with the carrier to locate it.
