Rapid Return Courier Service - Field Sampling and Delivery

Through UL's nation-wide network of qualified staff, we can do the sampling for you.  In some locations a friendly UL staff member can even come by with the sampling kit, pick up and deliver to our office, saving shipping costs and instilling confidence in your chain of custody.  Contact us at 1.800.332.4345 for more information or email: WaterInquiry@UL.com .

Claim Validation for water products    

UL supports manufacturers that want to differentiate their products by offering validation of manufacturer's marketing claims.  Having an independent third party assess and validate those claims brings an added level of confidence and may add a competitive advantage in the market place when consumers have a purchase option. 

Certification program for bottled water

As an industry leader in bottled water compliance analysis and plant inspection services, UL now offers a certification Mark designed specifically for producers of bottled water. The UL certified water quality Mark can add value to your brand because consumer market research shows that consumers prefer bottled water with the UL Mark.
