Designing and ordering UL Marks

There are two types of UL service: Type R and Type L. For new clients, your UL project engineer or customer service professional can inform you if the UL Mark for your product is under Type R or L service. If you are an existing client, this information is identified on the authorization page of the Follow-Up Services procedure.

Designing the UL Mark

As shown in the example below, the UL Mark consists of the appropriate UL symbol with the corresponding word "LISTED" or "CLASSIFIED," a product identification, a control number for Type R Marks or an issue or serial number for Type L Marks. (Recognized Components use a special symbol and marking requirements.)

The appropriate UL symbol and product identity may be found at UL's Online Certifications Directory by entering the UL Category Code Number (CCN) for the product and checking the box "Display Guide Information only." A UL project engineer or customer service professional can provide the CCN for the product or it will be identified on the authorization page of the Follow-Up Services procedure. 

• The control number is a fixed number assigned to Type R Marks and are associated with a specific UL file number.
• Issue or serial numbers are variable numbers used for Type L Marks and are assigned during the label ordering process.
• Additional markings may be required for a UL certified product. You may contact the project engineer for information on required markings for a product, or you may refer to the marking reference in the UL Follow-Up Services procedure.

Type R Marks

• Manufacturers of UL certified products are required to submit a copy of their UL Mark layout to a UL Label Center for review and, if acceptable, the layout will be stamped and returned.
• Type R Marks may be printed within a UL authorized manufacturing facility or at a UL Authorized Label Supplier. A copy of the UL stamped layout must be presented to or be on file with the Authorized Label Supplier when placing an order for Type R Marks.

Type L Marks

UL Marks for products under Type L Follow-Up Service and all product categories that require holographic labels are strictly controlled. All orders for these type labels must be processed through a UL Label Center.

There are two types of Type L Marks:

• Standard labels -- contain only the required elements of the UL Mark and additionally for some product categories will include a denomination such as feet, pieces, etc. Standard labels are printed and stocked by UL for select product categories. To confirm printing costs for Standard labels contact the Label Center servicing your manufacturing facility. To order Standard labels complete a label order form and direct it to the Label Center servicing your manufacturing facility. Response time to ship Standard labels is normally one to two days.
• Combination or custom labels -- include the UL file number or listee's name in addition to the same basic UL Mark information contained on the standard label and may also include other information. The manufacturer must submit a copy of the purchase order and label layout to a UL Label Center for review. If this is a reorder of a label already authorized by UL then only a copy of the purchase order is needed. The purchase order is required to include the name of the UL authorized label supplier, the UL file and volume number, the specific quantity of labels that are being printed, and the company name and address of the authorized manufacturing location that will use the UL labels. Upon successful review of the purchase order and Mark layout, the UL label center will issue an "Authorization To Manufacture UL Marks" to the authorized label supplier with a copy to the manufacturer and the appropriate UL Inspection Center. This authorization includes a general description of the UL Mark, the specific quantity of labels being ordered, and the UL issue or serial numbers that are required to be used on the UL Marks.

Charges associated with orders for Type L UL Marks

• Label service charge -- applies to many product categories under Type L service for the labels released or used. This charge defrays the cost for conducting periodic inspections at the manufacturing facility. Please contact your regional UL Label Center for additional information regarding the billing structure and specific fees for your product category.
• Manufacturing cost -- only charged when UL's standard labels are ordered. This charge reimburses UL for the printing costs and storage of these labels. This cost is not billed when combination labels are used since the manufacturer pays the printer directly for the printing and shipping cost of the labels.
• Shipping and handling fees -- invoiced by UL when UL Marks are sent to your manufacturing location directly from a UL Label Center. You may consult your local UL Label Center to identify these charges.

No refunds will be processed after 60 days from the date of the UL order.
