Which member of the acquisition team is responsible for determining the appropriate NAICS code?

The correct choice is the Contracting Officer (CO), who plays a critical role in the acquisition process, including the determination of the North American Industry Classification System (NAICS) code. The NAICS code is essential for identifying the business size and eligibility for certain programs, ensuring compliance with regulations such as those benefiting small businesses.

The CO's responsibility encompasses ensuring that the proper NAICS code aligns with the scope of work and the acquisition strategy. This task involves analyzing the nature of the goods or services being procured and selecting an appropriate code that fits within federal guidelines. Additionally, the CO must consider how the chosen NAICS code affects the procurement process, including small business set-asides and competition considerations.

Other team members, like the Program Manager or the Contract Specialist, may provide input or assist in the procurement process, but it is ultimately the responsibility of the Contracting Officer to finalize the NAICS code, reflecting the formal authority in the acquisition. The Small Business Liaison can support the acquisition team by advising on small business considerations but does not have the authority to determine the NAICS code themselves.
