Due to the highly diverse and fragmented nature of Grainger's customer base, there are no specific "major customer companies" that account for a significant portion of its net sales. Grainger explicitly states that no single customer accounts for more than 1% of its net sales. Therefore, instead of named companies, its customer base is best described by the following broad categories of businesses and institutions it serves:

• Large Enterprises and Strategic Accounts: These are large, often complex organizations across various industries such as manufacturing, healthcare, hospitality, transportation, and retail. These customers typically require comprehensive supply chain solutions, dedicated account management, and integrated e-procurement systems to manage their extensive MRO needs.
• Medium and Small Businesses (SMBs): This vast segment encompasses a wide array of businesses of varying sizes across virtually every sector. These customers value Grainger's extensive product offering, availability, convenience, competitive pricing, and efficient service for their daily operational requirements.
• Government and Institutional Entities: This category includes federal, state, and local government agencies, educational institutions (like universities and schools), and healthcare providers (such as hospitals and clinics). These customers often have specific procurement processes and require a reliable source for a broad range of MRO products to maintain their facilities and operations.
