Does Costco Do Propane Refills?

Propane refill is a convenient way to get your propane tank refilled quickly and easily. However, it is important to note that not all Costco store locations offer this service. To find out if your local store offers propane refill, simply call them or visit their website.

When calling, be sure to ask about any current promotions or specials they may be running on propane refill. For example, some locations offer a discount when you use their in-store coupon. Additionally, always remember to bring your own empty propane tank to the store – they will not be able to fill your tank if you do not have one.

Here’s a glimpse of the process:

Propane Tanks Accepted for Refill

When refilling propane tanks at retailers like Costco, there are specific criteria and specifications that tanks need to meet to be eligible for refill. These requirements are in place to ensure safety and adhere to regulatory guidelines. Here are some common criteria for propane tanks that are accepted for refill:

  • OPD Valve: Tanks need to have an Overfilling Prevention Device (OPD) valve, which is designed to prevent overfilling. Tanks with an OPD valve have a triangular handle.
  • Expiration Date: Propane tanks have a manufacturing or requalification date stamped on their collar. Typically, tanks are good for 12 years from the date of manufacture. After that, they need to be requalified, and if approved, they receive an additional stamp, which extends their use for another 5 years.
  • Tank Condition: Tanks should be free of excessive rust, dents, or other damages. Surface rust is typically okay, but deep rust that pits the surface can make the tank ineligible for refilling.
  • Capacity: Most refill stations, including those at Costco, typically handle common sizes like the 20-pound (BBQ grill size), 30-pound, 40-pound, and 100-pound tanks. However, not all locations might service all sizes, so it’s good to check ahead.
  • Valve Type: Tanks should have a standard fill valve to be eligible for refilling.
  • No Homemade or Modified Tanks: Any tank that appears to be altered or homemade will not be filled for safety reasons.
  • Visible Certification Marks: Tanks should display clear certification marks and stamps from recognized testing authorities. In the U.S., this might be from the Department of Transportation (DOT) or other relevant bodies.
  • No Obsolete Tanks: Older tanks with certain outdated features, such as a round or star-shaped hand wheel, might not be refillable. This is because they lack modern safety features, like the OPD valve.

When in doubt, it’s a good idea to inspect your tank before heading to a refill station or call the station in advance to inquire about specific requirements. Always remember that these regulations and guidelines are in place to ensure the safe storage and use of propane, a flammable and potentially hazardous material.

The Significant Thing Costco Checks is Whether the Tank Has expired or Has Not Been Re-certified.

Absolutely, the expiration or re-certification date on propane tanks is one of the most crucial aspects that Costco, and other propane retailers, check before refilling a tank. This is because using an expired or outdated tank can present significant safety risks.

Here’s a more focused breakdown of the expiration and re-certification process:

Understanding Propane Tank Expiration and Re-certification:

Manufacturing Date:

  • Every propane tank has a manufacturing date stamped onto its collar. This date indicates when the tank was produced.

Initial Validity:

  • Typically, a propane tank is valid for 12 years from the manufacturing date. For example, a tank manufactured in January 2020 will be valid until January 2032.


  • Once the initial 12 years have passed, tanks can be re-certified. This process involves a thorough inspection to ensure the tank’s safety and integrity.
  • If the tank passes the inspection, it’s stamped with a new date, extending its life for an additional 5 years from the re-certification date.
  • This process can be repeated, but as tanks age, the likelihood of them passing becomes slimmer due to wear and tear, potential damage, or outdated safety features.

How to Check:

  • To determine if your tank is expired, look for the date stamped on the collar of the tank. If 12 years have passed since that date and there’s no re-certification stamp, the tank is expired.
  • If there’s a re-certification stamp, check that date to ensure it’s within the valid 5-year range.

  • Expired tanks might not meet current safety standards, making them riskier to use.
  • Retailers, including Costco, prioritize the safety of their customers and employees, which is why they strictly adhere to these regulations.

If you plan to refill your propane tank at Costco or any other retailer, it’s essential to ensure your tank is either within its initial 12-year validity or has been successfully re-certified within the last 5 years. If in doubt, consult with the propane attendant or consider investing in a new tank. Safety should always be the top priority. Here’s a guideline.
