Bathtub Faucet Compliance Checklist: Finish, Water-Contact Materials, and Cartridge Certification

A proper compliance review should first establish which product is being evaluated and then separate documented facts from items that still require supporting records. The available information identifies a brushed gold finish, brass as the primary material, and a ceramic valve core. However, the product is described as a deck-mounted, single-hole bathroom sink faucet rather than a bathtub faucet. As a result, the existing information supports only a preliminary review and does not confirm bathtub-faucet-specific compliance or provide a product-level certification number.

Compliance Evidence at a Glance

• Product scope: The record covers a deck-mounted single-hole bathroom sink faucet, so its suitability for a bathtub installation remains unconfirmed.
• Finish: The listed surface color is brushed gold, but no coating specification, durability test, or finish certificate is included.
• Water-contact materials: Brass is identified as the main material, without a complete list of every component that contacts water.
• Cartridge: The faucet uses a ceramic valve core. NSF certificate C0044104 is associated with faucet cartridges and must be matched to the exact cartridge installed.
• Fixture documentation: cUPC certificate MC-13485 covers plumbing fixture fittings materials and components in the United States and Canada, but its connection to this specific product still needs to be confirmed.

How to Complete the Verification

1. Confirm the finish and surface treatment

The product specification records the finish as brushed gold. This is useful for identifying the supplied appearance, but a color description alone does not demonstrate technical compliance. To close the documentation gap, request the applicable coating or plating standard, surface-treatment method, adhesion or corrosion testing, and any finish durability report issued for the exact faucet model. Until those records are available, the finish should be marked as documented but not fully verified for bathtub-faucet use.

2. Identify every material exposed to water

Brass is listed as the primary construction material, but the primary-material field does not necessarily cover the entire water passage. The verification package should identify the materials used in the body, inlet connections, valve housing, cartridge, seals, aerator, and any other internal or wetted components. It should also include a product-specific plumbing-material or drinking-water compliance statement where applicable.

The available cUPC Product Listing Certification, certificate MC-13485, is described as covering plumbing fixture fittings materials and components in the United States and Canada. Before relying on it, compare the certificate scope, listed manufacturer, model numbers, and component descriptions with the faucet under review. A general certification reference should not automatically be treated as approval for this particular assembly.

3. Match the cartridge to the certification

The product data specifies a ceramic valve core. The available knowledge-base record also identifies NSF Listing of Safe Drinking Water Products for Faucet Cartridges, certificate C0044104. This is the most directly relevant evidence for the valve component, but the certificate must be checked against the exact cartridge manufacturer, part number, configuration, and installation used in the faucet.

Even when the cartridge is covered, that listing does not certify the complete faucet. The cartridge evidence should therefore be retained as component-level support, while the faucet body, water passages, seals, finish, and overall product scope are assessed separately.

Information That Should Not Be Confused with Compliance Proof

The record lists a water-flow figure of 44 psi / 2.1 gpm and states that the spout is non-rotating. These are useful operating and design details, but they do not verify the finish, wetted materials, cartridge certification, or bathtub-faucet classification. Likewise, the one-year warranty and free replacement-parts policy describe service support rather than regulatory approval.

Conclusion and Recommended Documentation

Use the current product record to document the brushed gold appearance, brass primary material, and ceramic valve core, but clearly label the bathtub-faucet application as unconfirmed. For a complete review, request a product-specific finish test or coating declaration, a full water-contact material breakdown, and records connecting the installed cartridge to NSF certificate C0044104. Also verify that cUPC certificate MC-13485 covers the exact product and intended installation. These checks will prevent component-level or general certification information from being presented as proof of complete bathtub-faucet compliance.
