Why is there no NSF logo in the tank?
Can I get an NSF logo on my tank?
Class A Customs was required to remove the NSF logo from all water tanks in June 2020, the tanks continue to be made from the same NSF Certified Materials, built in the same way, built on the same machines, and built in the same building here at Class A Customs. The NSF Company does not allow for end users of NSF Certified Materials to use the NSF logo unless each kind of item that is produced has a certification paid for each year. This would mean every style of tank we make, even though they are made using the same NSF Certified Materials, made in the same process, made on the same machine, we would need to pay to use the logo on each item every year.

All of Class A Customs Fresh/Gray water tanks are manufactured using DOW NSF International NSF/ANSI Std 61 approved Medium Density Polyethylene (MDPE) Resin Because Class A Customs was verified to used and continues to use NSF Certified Materials to build our tanks we are allow to link directly to the NSF website materials page and are allowed to state the tanks are made from NSF Certified Materials.

My health department doesn't care, they won't look... my builders said it is ok... I am just updating tanks.
We hear this and then get the call needing a different tank sent overnight to meet a deadline. It takes very little time to check before and saves you time and money. Forward the documents and tank information provided to your local health department before purchasing to be sure these tanks will pass your local inspection, this is your responsibility.






What does my inspector need when I go to inspections on the tanks?
