Key: R = Required; CR = Conditionally Required; [ ] = Brackets (i.e. [R],[CR]) indicate data requirements that
  apply when an experimental use permit is being sought; MP = Manufacturing Use Product, EP* = End Use Product;
  asterisk indicates those registrants that end-use applicants (i.e. formulators) need not satisfy, if their
  active ingredient(s) is (are) purchased from a registered source; TGAI = Technical Grade of the Active
  Ingredient; PAI = Pure Active Ingredient.
(b) Notes. The following notes are referenced in column two of the table contained in paragraph (a) of this
  section.
(\1\) Required if technical chemical is a solid at room temperature.
(\2\) Required if technical chemical is a liquid at room temparature.
(\3\) Required if technical chemical is organic and non-polar.
(\4\) Required if test substance is dispersible with water.
(\5\) Required if product contains an oxidizing or reducing agent.
(\6\) Required if product contains combustible liquids.
(\7\) Required if product is potentially explosive.
(\8\) Required if product is a liquid.
(\9\) Required if product is a emulsifiable liquid and is to be diluted with petroleum solvents.
(\10\) Required if end-use product is a liquid and is to be used around electrical equipment.
(\11\) Basic manufacturers are required to provide the Agency with a sample of each TGAI used to formulate a
  product produced by an integrated system when the new TGAI is first used as a formulating ingredient in
  products registered under FIFRA. A sample of the active ingredient (PAI) suitable for use as an analytical
  standard is also required at this time. Samples of end use products produced by an integrated system must be
  submitted on a case-by-case basis.
