(a) General. Sections 158.100 through 158.130 describe how to use this table to determine the product chemistry data requirements for a particular pesticide product. Notes that apply to an individual test and include specific conditions, qualifications, or exceptions to the designated test are listed in paragraph (f) of the section.
(b) Use patterns. Product chemistry data are required for all pesticide products and are not use-specific.
(c) Test substance. Data requirements that list only the manufacturing-use product as the test substance apply to products containing solely the technical grade of the active ingredient and manufacturing-use products to which other ingredients have been intentionally added.
(d) Key. R = Required; CR = Conditionally required; MP = Manufacturing-use product; NR = Not required; EP = End-use product; TGAI = Technical grade of the active ingredient; PAI = Pure active ingredient.
(e) Table. The following table shows the data requirements for product chemistry. The table notes are shown in paragraph (f) of this section.

(f) Test notes. The following test notes are applicable to the product chemistry data requirements in the table to paragraph (e) of this section:
1. Data must be provided in accordance with § 158.320.
2. Data must be provided in accordance with § 158.325.
3. Data must be provided in accordance with § 158.330.
4. Data must be provided in accordance with § 158.335.
5. Data must be provided in accordance with § 158.340.
6. Data must be provided in accordance with § 158.345.
7. Data must be provided in accordance with § 158.350.
8. Data must be provided in accordance with § 158.355.
9. If the TGAI cannot be isolated, data are required on the practical equivalent of the TGAI.
10. Data are required if the product is produced by an integrated system.
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.

22. Required when the test substance contains an acid or base functionality (organic or inorganic) or an alcoholic functionality (organic).
23. Required for water insoluble test substances (>10−6 g/l) and fibrous test substances with diameter of ≥0.1 µm.
24. Required if technical chemical is organic and non-polar.
25. Not required for salts.
