Products on List B

The following products are registered for use against Mycobacterium tuberculosis (TB). EPA has reviewed required laboratory testing data demonstrating that these products kill Mycobacterium tuberculosis.

Mycobacterium tuberculosis (TB) is a bacteria that normally attacks the lungs but can affect other parts of the body. Please see CDC’s website for more information. 

How to Use List B Products Effectively 

A product’s effectiveness can change depending on how you use it. Disinfectants may have different directions for different pathogens. Follow the label directions for Mycobacterium tuberculosis (TB) carefully including the contact time.

How to Read Registration Numbers 

Disinfectant products may be marketed and sold under different brand and product names. To determine whether EPA expects a given product to kill Mycobacterium tuberculosis (TB), check whether its registration is on this list.

• Registration numbers will have two or three parts
  •  The first two parts of this registration number reflect the primary registration, while the third part of the registration number identifies the distributor’s EPA company number.
  •  If your product's registration number has two parts (ex. 1234-12), it has a primary registration number. If this number is on List B, the product is qualified for use against Mycobacterium tuberculosis (TB).
  • If your product's registration number has three parts (ex. 1234-12-123), you have a supplemental distributor product. These products have the same chemical composition and efficacy as primary products, but often have different brand or product names. If this number is on List B, the product is qualified for use against Mycobacterium tuberculosis (TB).

How to Check if a product is on List B

• First, find the EPA registration number on the product label. Look for “EPA Reg. No.” followed by two or three sets of numbers, as described above.
• On the Disinfectant list, search the registration number exactly as it appears on the label.
• Once you see the results on the disinfectant list, make sure to check that the product's label includes directions for use against Mycobacterium tuberculosis (TB).
  • Regardless of whether you are using a primary registration product or a supplemental distributor product, always check the label has the corresponding directions for use for the relevant pathogen.
