Shipping Policy
To ensure your order is shipped safely and appropriately, we determine the shipping method based on weight, size, and handling requirements.
Parcel Shipments
Smaller items that meet standard carrier limits are shipped via common parcel carriers such as UPS, FedEx, or USPS. This is calculated for you automatically at checkout.
LTL Freight (Less-Than-Truckload)
Orders that:
Weigh over 150 lbs, or
Exceed parcel carrier size or dimensional limits
will ship via LTL freight.
LTL shipments are handled by third-party freight carriers and typically involve palletized delivery. Transit times and delivery scheduling vary depending on carrier availability, destination, and freight class.
Please note:
LTL deliveries often require a delivery appointment.
Liftgate service, limited access, or residential delivery may affect transit time and cost.
It is best to reach out to us before your purchase on items that exceed 150lbs or that are larger than 96 inches in any one direction in order to ensure that you get an accurate estimate on cost.
Full Truckload (FTL) / Specialized Freight
Large or specialized items—such as tanks, vessels, oversized equipment, or shipments requiring hazmat handling or oversized permits—are managed directly by Tri-State Supply.
These shipments may require:
Full truckload (FTL) transport
Oversized or overweight permits
Specialized carriers or equipment
Additional coordination prior to shipment
Because of this, processing and delivery timelines for full truckload or specialized freight are determined on a case-by-case basis. Our team will coordinate directly with you to confirm logistics before shipment. You will need to reach out to us for a quote. You may also arrange freight for your purchases. Loading fees, appointments, and more arrangements will still need to be agreed upon before something leaves our property.
Order Processing & Timing
Most in-stock orders are processed within 1–3 business days. Freight shipments—especially LTL and full truckload—may require additional time to schedule pickup and delivery.
Estimated delivery dates are provided as guidance and are subject to carrier and logistical factors beyond our direct control.
