Final answer:
The Title 5 exemption for trade secrets is the 'Confidential Commercial Information' exemption, which safeguards proprietary business details from public disclosure and competitive harm under FOIA.
Step-by-step explanation:
The United States Code Title 5 contains nine exemptions to records disclosure under the Freedom of Information Act (FOIA). The exemption that pertains specifically to trade secrets is the exemption for Confidential Commercial Information. This exemption is designed to protect sensitive commercial information, including trade secrets and proprietary business information, from disclosure. It prevents harm to the competitive stance of companies by keeping certain information out of the public domain. Agencies are compelled by FOIA to withhold such information when its disclosure is likely to cause substantial competitive harm.
