Follow-Up Services FAQ
The general services agreement also describes the terms under which Follow-Up Service inspections are conducted. For example, the manufacturer agrees to allow UL personnel immediate, unannounced and unrestricted access to any part of the facility in which UL certified products and components may be fabricated, assembled or stored.
Second, in-plant inspections are either billed at a fixed task rate or, for some product categories, at a per-label service charge. These fees vary depending on the product category and should be discussed with the FUS Label Group staff to get an estimated cost.
Third, follow-up sample fees may apply. Some clients may be subject to annual follow-up testing for their products and/or sub components. These also vary depending on the tests required.
During an IPI, the UL Representative performs a complete inspection of the product using the Follow-Up Service procedure, the same as in any regular inspection. If the product complies with the requirements described in the FUS procedure, the UL representative will release labels to the client to use on subsequent production. (There is no special charge for an IPI; regular FUS charges apply.)
In most respects, an IPI is like any other factory inspection. A major difference is that the UL representative schedules an IPI with the client rather than arriving unannounced. In addition, because the UL representative may not be familiar with the product and the factory, the IPI might take a bit longer than the regular inspection.
When a manufacturer splits the manufacturing process, UL must accommodate by similarly splitting the inspection process. The procedure describing the complete product is in place at both facilities. Special instructions to the UL representatives in the procedure explains what part of the manufacturing process takes place at each location as well as the responsibilities of the UL representative at each location. The procedure also describes an identifying mark that is applied at the first location to indicate to the UL representative at the second location that the subassembly was produced under the split inspection program. The inspection of the subassembly is not repeated at the second location.
Although there are additional expenses to the client to maintain Follow-Up Service at multiple locations, these costs are typically less than the costs to a manufacturer of obtaining, maintaining and operating multiple manufacturing operations.
TYPE R: Customers design the UL label layout and then submit it to the FUS label group for authorization. The manufacturer may use a label or a molding, stamping, etching, or silk-screening process to permanently apply the UL Mark. The UL Mark may stand alone, or it may be included as part of another marking such as a nameplate. The manufacturer may produce the label containing the UL Mark, or it may be obtained from a UL-authorized printer.
TYPE L: Customers must order the labels through their UL Label Center. UL Label Centers are located in various locations – please click here for UL Label Centers. Customers may choose to use a UL-authorized printer or order standard labels which UL stocks for some products. In some cases, in-house printing at the manufacturing facility of Type L labels is authorized. Whether manufacturers order our in-stock labels, use an authorized printer, or produce them in house, they must still request them through UL’s Label Center.
If a nonconformance with UL requirements is identified during a UL Marks Follow-Up Services factory inspection, the nonconformance will be documented and resolved through the Variation Notice process.
