Overview
This page is a scaffolded entry for HMTc Taxonomy v2.0 Category 12 (Household Cleaning and Dishwashing), Row 18: Drain maintainers/cleaners (including biological-based). Studies for this row are still being read. Where a section is empty, the row has not yet accumulated contributing sources of the required kind.
Literature scope
The Heavy Metal Index source corpus is currently focused on food and food-contact materials. This page documents an HMTc Taxonomy v2.0 row in the category Household Cleaning and Dishwashing for which no peer-reviewed primary or government sources have yet been ingested. The page exists as the routing destination for future ingest. Until sources land, the literature-evidence sections below are deliberately empty rather than guessed; HMTc certification thresholds for products in this row continue to be developed under the certification program at heavymetalcertified.com, not on this public page.
Reading guide
Legal, regulatory and retailer teams can use the cited measurements, applicable limits and study limitations to assess the evidence for this category.
Quality teams can examine product form, measurement basis and sources of variation. Journalists and researchers can follow each reference to the original findings and methods.

How standards math uses this page
HMT&C certification thresholds for this row are developed under the certification program at heavymetalcertified.com, not on this page. The row-standard for this row is an aggregate computed from the contributing source pool in the row’s native finished-product basis; it is not a per-source decoration of any single value cited on this page. This public page reports literature evidence only.
Historical recalls and enforcement
Public regulatory events for this row, such as recalls and import alerts, will be listed here as they are catalogued.
Methodology
This page reports what the cited sources say about heavy-metal concentrations in drain maintainers/cleaners (including biological-based). Speciation is non-substitutable (iAs vs tAs, MeHg vs tHg, Cr-VI vs total Cr). Basis is preserved (finished-product as sold unless the source specifies otherwise; see each row for the basis label). Non-detect handling follows each source’s reporting convention. Pooling is avoided across LOD/LOQ, period, geography, and analytical-basis differences. HMT&C certification thresholds for products in this row are developed under the certification program at heavymetalcertified.com, not on this page; this public page reports literature evidence only.
The applicable regulatory jurisdictions for this row are: EPA (Safer Choice), Green Seal, state disclosure laws.

The predecessor Program Policy on Household Cleansing Product Information Disclosure was declared null and void by the NYS Supreme Court (Household & Commercial Products Association v. Seggos, ruling issued August 2020); DEC maintains the present BMP document as recommended practice while moving forward to implement the underlying statute and regulation.
