Gas Cylinder Source knows you need your product now, which is why we offer super-fast shipping and even have an express option. We also recognize shipping charges can play a significant role in a purchase, and that is why we do everything we can to keep shipping rates as low as possible. We do not inflate the price of our products as a mask for free shipping offers. Our product prices are set at the best pricing we can offer, and the amount charged for shipping covers the shipping and delivery of your order. We believe this transparency in costs is the best way to keep you well-informed while receiving the best price available.

Calculate Your Shipping
You can calculate your shipping charge in just a few quick steps:

  • Add your desired product(s) to the shopping cart.
  • Navigate to the Shopping Cart page.
  • Click the "Calculate Shipping" link in the cart totals section and enter your Country, State, City, & Zip Code, then select the 'Update' button.

Residential vs Commercial Address
Initial shipping charges calculated in the Shopping Cart are figured using a residential shipping rate unless you have previously entered a commercial address in the ship-to field during a previous checkout session. Deliveries to a commercial address are typically cheaper than deliveries to a residential address and will be reflected on the checkout page once the full address has been entered and the system confirms it is a commercial address.

LTL Freight Shipments
For larger freight or custom orders, we ask you to allow for a 7-10 business day lead time for product preparation and shipping set up. A customer service representative may reach out to you requesting additional information such as liftgate needs, receiving hours, or other order details. Once your order has shipped, you will receive tracking information. LTL Freight Costs will be calculated on the day of shipment and may vary from your initial estimate, resulting in additional charges.

Time to Ship
Product is shipped from Minnesota. Transport time is usually between 1 and 5 days. Orders typically ship out the following business day after the order has been placed. Larger orders, and especially those going via a contracted freight service, may take additional time.

Order Tracking
Once your order has been shipped, an email will be sent to you with tracking details as well as a link you can use to track your shipment and find estimated delivery information.
