AIM offers [304 stainless steel](https://www.aimfaucet.com/wp-content/uploads/wp-mfa-exports/post/304-vs-316-stainless-steel-faucet.md) faucets for lead-free sourcing. ## **Which Rules Govern Lead-Free Faucets in North America?** North American buyers need to read federal and state rules together. California moved early with AB1953, while federal law later adopted the same 0.25% weighted average limit for wetted surfaces. California AB1953 took effect on January 1, 2010. It changed the state definition of “lead free” for pipes, fittings and fixtures used for water for human consumption. The law set a 0.25% weighted average limit for wetted surfaces. At the federal level, Congress passed the Reduction of Lead in Drinking Water Act in 2011. The law amended Section 1417 of the Safe Drinking Water Act and lowered the old lead allowance to a 0.25% weighted average for wetted surfaces. The EPA then issued its final Lead Free Rule in 2020. From September 1, 2023, manufacturers and importers introducing covered plumbing products into U.S. commerce became subject to the rule’s certification requirement. The purchase order should identify the market, product use and required certification before mass production. ## **What Does “Lead Free” Mean for a Faucet?** “Lead free” does not mean that every part must contain zero lead. Under the Safe Drinking Water Act, covered plumbing products must not exceed a weighted average of 0.25% lead across wetted surfaces. Solder and flux have a separate 0.2% limit. The calculation looks at parts that touch drinking water during normal use. In a faucet, this can include the body, waterway, connectors, valves, fittings and other internal components. A buyer should not approve a faucet from one raw-material report alone. The weighted average applies to the finished product’s wetted parts, so the full bill of materials matters. This also applies to a lead free [bathroom faucet](https://www.aimfaucet.com/wp-content/uploads/wp-mfa-exports/taxonomy/product_cat/bathroom.md) or lead free kitchen faucet. If the product supplies water for drinking, cooking, food preparation or oral hygiene, buyers should check applicable potable-water rules. ## **Why Is a Lead Free Brass Faucet More Complex to Source?** A lead free [brass faucet](https://www.aimfaucet.com/wp-content/uploads/wp-mfa-exports/post/brass-vs-stainless-steel-faucets.md) can meet North American rules, but procurement often needs tighter material control. Traditional free-cutting brass may contain more lead because lead has historically helped machining. Suppliers can use low-lead or lead-free copper alloys instead. One example is C87850, a copper-silicon alloy used for plumbing parts. These alloys can require different casting, machining, tooling and sourcing controls. B2B buyers should request the alloy number, material certificate, wetted-part list and product certification. They should also check whether the factory changed any alloy source or subcontracted part after approval. A cheaper brass quote may become less attractive if special alloy costs, supplier controls, testing and document checks add more work. ## **Why Can Stainless Steel Simplify Lead-Free Sourcing?** 304 and 316 stainless steel do not normally use lead as an intentional alloying element. That gives stainless steel a simple starting point for lead-content control compared with many traditional brass formulas. For a buyer, that can reduce one layer of raw-material screening. It does not remove finished-product testing. The supplier still needs stable material records, controlled component sources and documents that match the exact faucet model. This distinction is important when several suppliers quote similar products. This is useful when an importer compares several factories because a clear component list makes material changes easier to spot before certification, production and final shipment approval. Still, stainless steel does not make a complete faucet compliant by itself. Cartridges, hoses, aerators, connectors, seals and other wetted parts must also fit the required compliance plan. The material choice can simplify the first screening step, but buyers should still check every wetted component and the certification file. ![How Should B2B Buyers Verify Lead-Free Faucet Compliance?](https://www.aimfaucet.com/wp-content/uploads/2026/08/image-50-1200x900.webp) ## **How Should B2B Buyers Verify Lead-Free Faucet Compliance?** Buyers should verify both lead content and what the finished faucet may release into drinking water. The certificate should match the model ordered. ### **Check NSF/ANSI/CAN 372 for Lead Content** [NSF/ANSI/CAN 372](https://www.aimfaucet.com/wp-content/uploads/wp-mfa-exports/post/nsf-faucet-importance.md) addresses lead content and provides a method to show that a product meets the 0.25% weighted average requirement. Buyers should look for a valid third-party listing that covers the exact model or product family. Do not accept a report that names only the factory. Check the model, material option, certification body, listing status and scope. ### **Check NSF/ANSI/CAN 61 Section 9 for Leaching** NSF/ANSI/CAN 61 evaluates health effects from substances that may leach from drinking-water products. Section 9 covers endpoint devices such as faucets, flexible connectors and stop valves. Lead-content compliance and leaching performance are related but different checks. A strong sourcing file should include the certificate, third-party test report, bill of materials, material records, drawing and approved sample. If buyers compare lead free faucet brands, they should compare the certification scope, not only the logo printed on the carton. ## **What Can Happen If a Faucet Is Not Compliant?** A noncompliant faucet can create legal, financial and brand risk. EPA states that manufacturers and importers may face enforcement and penalties for introducing covered plumbing products that are not properly certified as lead free. A buyer may also face held stock, rejected shipments, retailer delisting, replacement costs or product withdrawal. The exact result depends on the case and market. Reputation can be harder to repair. A lead-free claim is simple to print, but customers and retail partners may ask for proof after a compliance problem. Make certification a shipment-release condition. The ordered model, material option, listing and test file should all match before final payment or delivery approval.

Confirm wetted parts, certification scope and third-party records before North American import approval. ## FAQs ### How do I know if my faucet is lead free? Check the third-party certification listing under NSF/ANSI/CAN 372 for the exact model number — not just the brand or factory. Since September 2023, the EPA also requires importers introducing covered plumbing products into US commerce to certify compliance. ### What does lead free mean for a faucet? Under US federal law, “lead free” means a weighted average of no more than 0.25% lead across all wetted surfaces — not zero lead. The calculation must include every wetted component: body, cartridge, hoses, aerator, and connectors. ### What certifications are required for lead free faucets in the US? NSF/ANSI/CAN 372 covers lead content; NSF/ANSI/CAN 61 Section 9 covers what the faucet releases into drinking water. Both must be held for the exact model being sold, not a similar model or the factory generally. [Get a Free Quote](https://www.aimfaucet.com/wp-content/uploads/wp-mfa-exports/page/contact-us.md)
