45 CFR 2105.29: What must a submitter include in a detailed Exemption 4 objection statement?

If a submitter has any objections to disclosure, it should provide the Agency a detailed written statement that specifies all grounds for withholding the particular information under any exemption of the FOIA. In order to rely on Exemption 4 as basis for nondisclosure, the submitter must explain why the information constitutes a trade secret or commercial or financial information that is confidential.
