Shipping, Delivery, Order Processing & Product Availability
Fondriest uses the best carriers to make sure orders gets to you on time. Learn more about shipping times, methods, costs, and carriers.
Delivery Time
We keep you informed. Shortly after you place your order, you will receive an Order Acknowledgement email to confirm your order details, including shipping and a delivery estimate. Once your order has been prepared for shipment and ships, you will receive a Shipment Notification email with carrier and tracking information.
Shipping and Delivery Estimates
The 'Ships' timeframe is an estimate of when the item will ship from our warehouse. All items will ship at one time unless you specifically request partial shipment. In which case, the items on your order will ship as they become available. The 'Delivers' timeframe is an estimate of when the item will be delivered to your shipping address after it ships. The estimated delivery time depends on the shipping method you choose during checkout. All estimates are based on business days.
Shipping Options
Fondriest offers several convenient shipping options via UPS.
| Ground Shipping: | Products shipped via ground service are normally delivered within five business days after shipment. |
| 2-Day Shipping: | For an additional charge, Fondriest offers 2-day shipping for most products. Products shipped via two-day service prior to 4:00 p.m. EST are normally delivered by 7:00 p.m. local time two business days after shipment. |
| Overnight Delivery: | For an additional charge, Fondriest offers overnight shipping for most products. Products shipped via overnight service prior to 4:00 p.m. EST are normally delivered by 7:00 p.m. local time one business day after shipment. Earlier overnight delivery options may also be available depending on the destination. |
| Your Account: | For no additional charge, Fondriest can ship on third-party customer accounts via UPS and FedEx. Note that FedEx Ground shipments are picked up the following business day and Express shipments must be made before 1:00 p.m. EST to ensure same-day pick-up. |
Remember that these estimates are for time in transit only, and that they do not apply until the product leaves the Fondriest warehouse. As the delivery of your order is beyond Fondriest's control once your order leaves the Fondriest warehouse, we cannot assume liability for late deliveries, regardless of the delivery method you specify.
Signature Required on Most Deliveries
Most of Fondriest's shipments contain valuable equipment. If you will not be at the shipping address to accept delivery of your product, consider shipping the item to an address where someone you trust will be available to sign for your package, or accept your package if a signature is not required for the delivery. Once your order has prepared for shipment or has shipped, we are unable to change the shipping address. Title and risk of loss to all products will pass to you on delivery. If you are willing to assume the risks of delivering your order without a signature, you may authorize Fondriest to arrange for a delivery that does not require anyone to be at the delivery address.
Undeliverable Packages
Occasionally packages are returned to Fondriest as undeliverable. When the carrier returns an undeliverable package to Fondriest, please contact us to make arrangements for reshipment.
Failed Delivery Attempts
Most of Fondriest carriers make three attempts to deliver a package. After three delivery attempts, the carrier will return the package to Fondriest.
Order Processing
The estimated shipment date on your order is based on product availability, payment processing time, and warehouse processing time and does not include transit time. We do not begin payment processing until Fondriest receives all of the information that is needed and full payment or a full authorization, in the case of credit card or rental orders.
Fondriest will begin payment processing for orders placed on weekends or holidays on the next business day. Business days are Monday through Friday, excluding federal holidays.
Your order for in-stock items that are eligible for same-day shipping must be received before your local time of 2:00 p.m., pending payment processing, for there to be adequate remaining time in the day for your order to be dispatched.
Product Availability
Fondriest makes every effort to ship your product according to the estimated lead times. The estimated lead times are in business days (Monday through Friday, excluding federal holidays).
Although Fondriest makes every effort to ship your order according to the lead time provided, shipping dates may change due to changes in supply. If the lead time changes, Fondriest will contact you via email and provide a revised shipping estimate.
Fondriest makes every effort to supply the products you order, but there may be occasions when Fondriest confirms orders and later learns that it cannot supply the products, either at all or in the quantities ordered. Although rare, these occasions can include when Fondriest learns that the products no longer are being manufactured or they otherwise become unavailable, when Fondriest cannot source components for the configuration you ordered, or when there was a pricing error at the Fondriest Online Store.
In those circumstances, Fondriest will inform you and, if you are interested, Fondriest may suggest alternative products that may meet your needs. If you do not wish to order alternative products, Fondriest will cancel your order for products that cannot be supplied and for any other products that you no longer wish to order as a result, and will refund your purchase price.
We want you to be completely satisfied with your purchase. If you are not, you may initiate a return within 30 calendar days of receiving your item(s). To begin a return, you must request a Return Material Authorization (RMA) by either contacting your account representative or the general customer support address: customercare@fondriest.com. Returns without an RMA will not be accepted.
Items returned for credit must be new, unused, and in the original packaging (including any accessories, manuals, and documentation that shipped with the product). Returned items must be received by Fondriest Environmental within 14 calendar days of the issuance of the RMA. All returned items are subject to inspection and approval prior to the issuance of any credit. If the returned items have been approved, Fondriest will issue a credit based on the original method of payment. Please note that items may be subject to a manufacturer's restocking fee.

How NOAA’s CURBY Aided Recovery Efforts After the 2025 DCA Plane Crash
On the evening of January 29, 2025, a military helicopter and an American Airlines flight collided midair over the Potomac River on the final approach into Ronald Reagan Washington National Airport (DCA) in Virginia, five miles from Washington, D.C. The incident marked the first major U.S. commercial airline crash in over 15 years and resulted in the tragic loss of all passengers and crew. In the immediate aftermath of the tragedy, emergency response agencies mobilized to search for survivors and begin recovery operations. As part of the broader interagency effort, NOAA provided environmental observing support to aid on-site teams working in challenging conditions.
Expanding the Port Everglades: Real-Time Monitoring of Water Quality Conditions from Planned Dredging Operation
The Port Everglades in Broward County, Florida, serves large trade vessels and cruiseliners and incoming and outgoing recreational boaters. However, as cargo ships become larger, the port must expand. A dredging project led by the US Army Corps of Engineers will substantially deepen and widen the port's navigation channel to accommodate larger Panamax cargo ships and modern cruise liners. As a result of this project, a large amount of sediment will be displaced into the water column. This suspended sediment may settle outside of the project area, burying benthic organisms like corals, and possibly carrying harmful particulates to other regions.
Current Monitoring after the Francis Scott Key Bridge Collapse
On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.
