HUBZone Certification for Manufacturing Companies

For small businesses located in Historically Underutilized Business Zones.

Manufacturing offers significant opportunities for certified diverse suppliers. Here's why certification matters:

OEM Requirements: Major automotive companies (Ford, GM, Toyota) and aerospace companies (Boeing, Lockheed Martin) have aggressive diverse supplier targets.

Tier 1 Subcontracting: Large Tier 1 suppliers must flow diversity requirements down the supply chain.

Made in USA: Federal and corporate "Buy American" requirements create opportunities for domestic diverse manufacturers.

Supply Chain Resilience: Post-pandemic, corporations are diversifying supply chains and seeking domestic diverse suppliers.

Long-term Contracts: Manufacturing relationships tend to be longer-term than services, providing revenue stability.

Automotive OEMs alone spend over $150 billion annually with suppliers, with significant portions targeted to diverse businesses.

Principal office must be in a HUBZone, 35% of employees must reside in a HUBZone.

HUBZone certification has three hard requirements: principal office location, employee residency, and ownership. All three must be met at the time of certification and maintained continuously.

Principal office location The business's principal office (where the majority of employees report, where management works, and where the most business activity occurs) must be located in a qualified HUBZone. A P.O. box, virtual office, or registered-agent address does not qualify. Verify the exact street address at maps.certify.sba.gov before doing anything else. HUBZone maps are updated annually; an address that qualified last year may not qualify today.

Employee residency (the 35% rule) At least 35% of your employees, counted by headcount, must live in a HUBZone. The percentage is computed on the number of employees and rounded to the nearest whole number: 10 employees means at least 4 must reside in a HUBZone (25 employees means 9). Hours matter only for deciding who counts as an employee; anyone who generally works a minimum of 10 hours per week during the four-week period before review counts, including part-time workers. SBA can examine payroll records and require employees to document their residential addresses with utility bills or driver's licenses.

Ownership The business must be 51% owned and controlled by one or more U.S. citizens, a Community Development Corporation, an agricultural cooperative, or a Native American tribe or Alaska Native Corporation (ANC). Tribally-owned and ANC-owned firms face no SBA size restrictions.

Size The firm must qualify as small under SBA size standards for its primary NAICS code. Verify at sba.gov/size-standards.

Step 1: Verify the principal office address Go to maps.certify.sba.gov and enter your exact business street address. Do this before anything else. HUBZone designations are updated every year; the map reflects the current status. If your address does not qualify, stop here and evaluate whether relocating the principal office makes business sense.

Step 2: Calculate the 35% employee residency ratio Pull your most recent payroll records. List every employee and their home address, and confirm who counts as an employee (generally anyone working at least 10 hours per week in the four weeks before review). For each employee, check whether their home address falls in a HUBZone using the same map tool. Calculate: HUBZone-resident employees ÷ total employees, rounded to the nearest whole number of required residents. If the result is below 35%, you are not currently eligible. Document this calculation; SBA may ask for it.

Step 3: Confirm SAM.gov registration is active HUBZone applications require an active SAM.gov registration. Confirm it's current and lists your HUBZone office address as your primary place of business.

Step 4: Gather documentation Before opening the certify.sba.gov application, have these ready: a signed lease or deed for the principal office address; proof of employee home addresses (driver's licenses, utility bills dated within 90 days); payroll records showing hours by employee; ownership documents (operating agreement, stock certificates, or membership ledger); and business tax returns for the past two years.

Step 5: Submit the application at certify.sba.gov The online application asks for business details, employee data, and document uploads. Be precise about how you calculate the 35%; SBA reviewers check the math.

Step 6: SBA review SBA targets a 60-90 day review period. Incomplete applications or address conflicts will trigger a request for additional information. Respond within 15 days.

Step 7: Program examination and ongoing compliance After certification, SBA can conduct a program examination at any time to verify continued eligibility. Maintain a residency log for all employees. If any employee moves out of a HUBZone, recalculate your ratio immediately. If a redesignation removes your office area from HUBZone status, you have a 3-year transition period during which you remain certified (per SBA redesignation rules).

Federal Manufacturing Opportunities

Key agencies purchasing manufactured goods:

• Department of Defense (DoD): Largest federal buyer of manufactured goods
• Defense Logistics Agency (DLA): Military supplies and equipment
• General Services Administration (GSA): Office products, furniture, equipment
• NASA: Aerospace manufacturing and components

Key Requirements

• Buy American Act: Many federal purchases require domestic manufacturing
• Berry Amendment: Certain DoD purchases must be 100% US-made
• CMMC: Cybersecurity requirements for defense manufacturing

Small Business Set-Asides: Manufacturing NAICS codes have specific size standards - many "small" manufacturers are substantial operations.
