The Product Service Codes (PSC) and North American Industrial Classification Systems (NAICS) are the two methods that the Federal government classifies contracts. They are used as a mechanism to identify scope of the products and services and business segment covered under the award. This data can be used as a mechanism to understand the scope of GSA programs. This can be used as means to identify best fit. While a GSA contract can offer great opportunities for many businesses, the process of applying for that contract will take a significant amount of time and resources. Understanding best GSA contract for your products and services is a preliminary step to take prior to responding to a GSA solicitation.

The enclosed files are crosswalks between the 2012 editions of the Census industry and North American Industry Classification System (NAICS) codes, from 2- to 6-digit NAICS codes.

The North American Industry Classification System (NAICS) is an industry classification system developed by the statistical agencies of Canada, Mexico and the United States. Created against the background of the North American Free Trade Agreement, it is designed to provide common definitions of the industrial structure of the three countries and a common statistical framework to facilitate the analysis of the three economies. NAICS is based on supply-side or production-oriented principles, to ensure that industrial data, classified to NAICS, are suitable for the analysis of production-related issues such as industrial performance.

The Small Business Size Standards APIs power the following application: https://www.sba.gov/size-standards/, which can be used to determine if a business qualifies as small. This API retrieves a specific property of a specific NAICS code.

To help provide a level playing field for women business owners, the government limits competition for certain contracts to businesses that participate in the Women-Owned Small Business Federal Contracting Program (WOSB Program). These contracts are for specific industries where women-owned small businesses are substantially underrepresented. Some contracts are restricted further to economically disadvantaged women-owned small businesses (EDWOSBs). SBA maintains a list of those eligible industries and their North American Industry Classification System (NAICS) codes. Of the 759 eligible industries, 646 are designated for limited competition among all WOSB Program participants, and 113 are eligible for competition among only SBA-certified EDWOSBs. Congress requires SBA to conduct a study every five years to identify industries in which small businesses owned and controlled by women are underrepresented in the Federal marketplace.

Introduction

ExioNAICS is the first enterprise-level ML-ready benchmark dataset tailored for GHG emission estimation, bridging sector classification with carbon intensity analysis. In contrast to broad sectoral databases like ExioML, which offer global coverage of 163 sectors across 49 regions, ExioNAICS focuses on enterprise granularity by providing 20,850 textual descriptions mapped to validated NAICS codes and augmented with 166 sectoral carbon intensity factors. This design enables the automation of Scope 3 emission estimates (e.g., from purchased goods and services) at the firm level, a critical yet often overlooked component of supply chain emissions.

ExioNAICS is derived from the high-quality EE-MRIO dataset, ensuring robust economic and environmental data. By integrating firm-specific text descriptions, NAICS industry labels, and ExioML-based carbon intensity factors, ExioNAICS overcomes key data bottlenecks in enterprise-level GHG accounting. It significantly lowers the entry barrier for smaller firms and researchers by standardizing data formats and linking them to a recognized classification framework.

In demonstrating its usability, we formulate a NAICS classification and subsequent emission estimation pipeline using contrastive learning (Sentence-BERT). Our results showcase near state-of-the-art retrieval accuracy, paving the way for more accessible, cost-effective, and scalable approaches to corporate carbon accounting. ExioNAICS thus facilitates synergy between machine learning and climate research, fostering the **integration** of advanced NLP techniques in eco-economic studies at the enterprise scale.

Dataset

ExioNAICS serves as a hybrid textual and numeric dataset, capturing both enterprise descriptions (text modality) and sectoral carbon intensity factors (numeric modality). These data components are linked through NAICS codes, allowing end-to-end modeling of how enterprise descriptions map to sector emission intensities. Key dataset features include:

- Enterprise Description
- NAICS Description
- Sectoral Emission Factor
- Over 20,000 textual entries
- Hierarchical coverage: NAICS 2–6 digit codes (20 to 1,114 categories)

NAICS Classification

NAICS Classification is a fundamental component of enterprise-level GHG emission estimation. By assigning each firm to the appropriate sector category, practitioners can reference the corresponding carbon intensity factors, facilitating more accurate reporting. ExioNAICS adopts a natural language processing approach to NAICS classification, treating the task as an information retrieval problem.

Each enterprise description (query) is encoded separately, and matched against NAICS descriptions (corpus) based on the cosine similarity of their embeddings. This methodology leverages a dual-tower architecture, wherein the first tower processes the query (enterprise text) and the second tower processes NAICS descriptions.

We apply machine learning to fine-tune a pre-trained Sentence-BERT model. Zero-shot SBERT models may achieve only around 20% Top-1 accuracy on the 1000 classes sector classification task, whereas contrastive fine-tuning raises this to over 75%. Further preprocessing exceeding 77% Top-1 accuracy, such as lowercasing and URL removal, can add incremental gains, leading to state-of-the-art results.

Percentage of enterprises that exported and did not export goods or services outside Canada, by North American Industry Classification System (NAICS) code and enterprise size, based on a one-year observation period. Enterprises that exported are broken down into exporters with unsuccessful attempts to export to additional markets, and exporters with unsuccessful attempts to export additional goods or services. Enterprises that did not export are broken down into non-exporters with unsuccessful attempts to export.
