Domestic Flanges
BABA/AIS Certified Flanges for Federally-Funded Water Utility and Public Works Projects
Meet Buy America Requirements
Federally-funded water utility and infrastructure projects are subject to strict Buy America Act (BAA) and American Iron and Steel (AIS) requirements. These regulations mandate that materials and products used in such projects be produced in the United States using domestic materials and labor. API Flange specializes in supplying flanges that fully comply with these requirements, enabling municipalities, water authorities, and contractors to meet federal funding mandates while sourcing quality products from a trusted domestic supplier.
Our commitment to domestic sourcing goes beyond mere compliance. We work exclusively with American mills and forging facilities to deliver the quality that has made API Flange a trusted partner for water utility projects nationwide.

Frequently Asked Questions
Do all water utility projects require BABA/AIS compliance?
Only projects funded with federal dollars (EPA, HUD, DOT, etc.) are subject to BABA/AIS requirements. However, many states have similar domestic sourcing mandates. We recommend verifying requirements with your funding agency.
What documentation do I need to submit to prove BABA/AIS compliance?
Generally, you need material certifications (MTRs), production location documentation, domestic sourcing certification, and pressure test reports. We provide all necessary documentation with every order.
Are there any additional costs for BABA/AIS certified flanges?
Our domestic flanges are competitively priced. Since these products are sourced from U.S. mills and forging facilities, BABA/AIS compliance is built into the supply chain.
Can you supply custom domestic flanges?
Yes. We can source custom flanges from domestic mills while maintaining BABA/AIS compliance. Contact us to discuss your specifications.
What are typical lead times for domestic flanges?
Standard size flanges typically ship from stock to 4 weeks. Custom orders vary based on complexity. We work to accommodate project schedules whenever possible.
Who can verify that your flanges meet BABA/AIS requirements?
Your project engineer, procurement department, or funding agency can review the documentation we provide. Many agencies have specific verification procedures we can support.
