Low Volume Exemptions


Certain categories of new low-volume chemical substances are exempt from full premanufacture notice (PMN) review under section 5 of the Toxic Substances Control Act (TSCA), i.e., chemicals manufactured at 10,000 kg/year or less. LVE substances undergo a 30-day review and are not subject to a user fee.

Note: On the opening screen (General Form Information, PMN page 1) of the Premanufacture Notice form, be sure to select from the dropdown list the type of notice you are submitting: LVE Modification. You must also mark the certification statements on PMN page 2 and fill out the contact information on PMN page 3. You can enter the rest of the modification information into the form in one of three ways:

  1. fill in the applicable fields in the PMN pages 4-13;
  2. enter the modification information in the cover letter; or
  3. enter the modification information as an attachment.

It should be noted that for modifications, the e-TSCA/e-PMN software does not validate any data beyond PMN page 3.
