Section 5: What are the types of labels and labeling?  

Types of Labels and Labeling

The four types of labels and labeling are: master label, sub-label or split-label, supplemental distributor labeling, and supplemental labeling.

Master Label

A master label contains claims and directions for all of the approved uses for a given product and all associated required labeling. All other labeling for a given product (with the exception of supplemental labeling) must not contain any text beyond that which is approved in the master label. This label goes on file with the EPA once it is stamped “accepted.”

Sub-Label or Split-Label

A sub-label or split-label contains claims and directions for only a portion of the approved uses under a given master label, but is a complete label in itself, containing all of the required labeling elements. This is usually done for marketing purposes. EPA regulations allow a registrant to distribute or sell a product under a sub-label or split-label provided that, in limiting the uses identified on the label, no changes would be necessary to the precautionary statements, use classification, or packaging of the product.

A sub-label or split-label only contains labeling text that also appears on the master label. When a sub-label is submitted with additions not on the accepted master label, a new master label containing all the uses currently approved under the product's registration is required. Only the master label will be stamped “accepted.” 


For more details about sub-labels/split-labels, see Chapter 3, Section IV.B of the Label Review Manual.
