NAICS codes by domain

The contract scope of OASIS+ is organized by domains, functional grouping of related services. Each domain contains multiple North American Industry Classification System (NAICS) codes. We will release domains in phases: there are eight domains that comprise the scope of the initial Phase I. We have included a list of NAICS codes for Phase I domains below, and will continue to build on this list when we release Phase II.

Determining the appropriate primary NAICS code

OASIS+ domains contain multiple NAICS codes. FAR 19.102 requires the OCO to determine the appropriate NAICS code and related small business size standard and include them in all solicitations above the micro-purchase threshold. FAR 19.102(b)(1) requires that the NAICS code assigned describe the principal nature of the service being acquired.

The primary NAICS code for all OASIS+ UR contracts will be selected and assigned based on the smallest size standard within its awarded Domains. When the OASIS+ CO assigns a primary NAICS Code, receipts-based size standards take precedence over NAICS codes based on employees. This primary NAICS code will be reflected in each awarded contract and associated FPDS record. However, assignment of a primary NAICS code does not limit contractors’ eligibility to respond to task order solicitations or perform work outside of the NAICS assigned as their primary NAICS on their contract. Contractors will be eligible to compete within all awarded Domain CLINs (NAICS codes), which represent the contractor’s specific fair opportunity pools.

The primary NAICS code for all OASIS+ SB contracts will be selected and assigned based on the largest size standard within its awarded Domains. When the OASIS+ CO assigns a primary NAICS code, employee-based size standards take precedence over NAICS codes based on annual receipts. This is critical to ensure contractors are not locked out of Domain fair opportunity during re-representation in accordance with Section G.3.1.7.2, as long as they are otherwise eligible based on their size standard at time of re-representation.

Understanding primary-level NAICS codes vs task order-level NAICS codes

For administrative purposes only, the six OASIS+ solicitations are assigned a single NAICS code (541990) which represents the preponderance scope of the OASIS+ Contract Program as a whole. This is not the NAICS that will be reported at the task order level.

FPDS is currently designed to accept only one NAICS code to be associated with a procurement action. This is simply a limitation of the FPDS system and has no bearing on individual task order NAICS code assignments. The OASIS+ process of NAICS code assignment at the individual master contract level is for administrative purposes, and will ensure proper socioeconomic and size status reporting at the task order level. Due to a limitation with the FPDS, only a single NAICS code may be assigned to a contract and subsequently reported with each contract action (i.e., task order); therefore, each contractor will be assigned a single primary NAICS code to its master contract based on its awarded Domains. This primary NAICS code will be reflected in each awarded contract and associated FPDS record. However, assignment of a primary NAICS code does not limit contractors’ eligibility to respond to task order solicitations or perform work outside of the NAICS assigned as their primary NAICS on their contract. contractors will be eligible to compete within all awarded Domain CLINs (NAICS codes), which represent the contractor’s specific fair opportunity pools. Fair opportunity will be managed in the OSP, which will be the mandatory, sole system for OCOs to issue task order solicitations. The contractor will only be included in and allowed to compete under the NAICS codes where they are represented (and subsequently re-represent) as a small business concern for the corresponding size standard, and are otherwise eligible under the socioeconomic contract.
