Prop 65 Compliance for Canned Food Linings (Bisphenols: BPA/BPS + No Oral MADL + Class Listing Risk + Migration Testing)

Why This Matters

Can linings are now a high-velocity Prop 65 enforcement target because bisphenols have no oral safe harbor in the brief’s framing: when there is no oral MADL established, any detectable migration trace can become a 60-day notice trigger. The “BPA-free” era is not a finish line—it is a substitution cycle that can accelerate enforcement risk.

Prop 65 Enforcement Trends (2024–2026)

The brief positions canned foods and supplements within the largest enforcement channel and shows continued acceleration in overall NOV volume. When food-contact packaging becomes the exposure vector, documentation quality becomes the primary defense lever.

• 5,000+ NOVs in 2025 (overall enforcement volume referenced)
• ~64% food & supplements share (largest category share in the brief’s Q1 2026 view)
• 900+ BPS NOVs in 2025 (surge after enforcement began Jan 1, 2025)

Why Can Linings Are at Risk (The Regrettable Substitution Timeline)

The brief highlights that single-chemical strategies are obsolete because substitutes become targets—and proposed class listing would catch most “BPA/BPS-free” positioning.

• 2015: BPA listed (reproductive toxicant); industry shifted to “BPA-free” epoxies/acrylics
• 2024: BPS listed (Dec 29, 2024), enforceable Jan 1, 2025; rapid 2025 enforcement surge
• 2025–26: p,p′-bisphenol class under review (BPA, BPS, BPAF, BPAP, BPB, BPZ + esters/ethers)
• 2026+: class listing expected per brief posture; substitutes become captured by design

The brief’s durable strategy: track the arc, audit upstream coating chemistry, and maintain defensible migration testing files.

Business Impact of Non-Compliance

In food packaging, enforcement pressure is amplified by retailer compliance demands and the speed of supplier chemistry changes.

• 60-Day Notice of Violation: brand owner, private-label operator, importer, and retailer can be named on one NOV
• Class action exposure: the brief references major brands named in recent bisphenol actions
• Supplier substitution cycle: every coating change restarts testing, revalidation, and stability timelines
• Retail delisting risk: major retailers require documented food-contact material compliance

What We Deliver

The brief defines an end-to-end program built for packaging-driven exposure: can/coating mapping, migration testing oversight, supplier controls, and forward monitoring for class listing.

• Product & can risk assessment
• Migration testing oversight
• Exposure evaluation
• Compliance determination
• Warning label strategy
• Coating supplier compliance program
• Substitution roadmap
• Class-listing forward monitoring

Core Technical Components

The compliance stack underneath every determination (from the brief).

• Migration testing (LC‑MS/MS): BPA, BPS, BPAF, BPAP, BPB, BPZ plus PFAS and selected phthalates—using food-contact simulant protocols
• Coating chemistry audit: epoxy, acrylic, polyester, olefin resins classified by bisphenol content and substitute chemistry—formulations documented
• Exposure evaluation: serving-size math with no safe harbor posture—documentation must show control below detection, not “below MADL”
• Coating supplier attestation: per can lot: coating supplier, resin chemistry, migration COA; chemical compliance warranties and indemnification controls
• Class-listing forward strategy: supply-chain review for all class members, not only BPA/BPS

Supply-Chain Compliance Control

Prevent the issue upstream—before it reaches your label.

• Coating supplier attestation: resin chemistry declarations from coating manufacturers
• SKU-to-can mapping: which SKU uses which can, from which can-maker, with which coating formulation
• Migration testing: each can/coating combination tested in food simulants matching product pH and fat content
• Substitution roadmap: BPA → BPS-free → class-compliant alternative; validation timelines aligned to regulatory milestones

The SystemsBuilder Approach (Artifacts vs Records)

The brief’s method is artifact-based: build the structure once (testing program + coating audit + decision logic), then generate unlimited lot records without rebuilding the program each time.

• Artifact (you pay): one document defining how migration testing, coating audits, and substitution decisions are recorded
• Records (no added cost): unlimited batch/lot test results and supplier records under the same framework
• Result: scalable, predictable, cost-efficient, and defensible

How It Works (Three Phases)

Step 01 — Setup

• SKU & can-source inventory
• Coating chemistry audit
• Migration testing plan
• Documentation structure

Step 02 — Implementation

• Food-simulant migration tests
• Prop 65 exposure evaluation
• Warning label determination
• Substitution roadmap kickoff

Step 03 — Monitoring

• Monthly compliance oversight
• Class-listing surveillance
• Supplier chemistry updates
• Audit-ready reporting

Pricing (From the Brief)

• Setup (one-time): $1,500 up to 3 finished products (SKUs) + $150 each additional SKU
• Monthly monitoring: $500/month up to 7 finished products + $50/month per additional SKU
• Testing monitoring fee: $35 per testing monitoring event (per lot/batch)

Laboratory testing fees are not included; testing is conducted by independent ISO 17025 accredited laboratories and billed directly by the laboratory.

What You Receive

• Batch compliance review reports: per-lot pass/fail determination, threshold comparison, reviewer sign-off
• Monthly summary reports: rolling snapshot of events, compliance status, and open action items
• Compliance monitoring logs: date-stamped log of every decision made
• Supplier tracking records: attestations, COAs, risk ratings, and corrective actions by supplier
• Audit-ready documentation: packaged for OAG inquiries, retailer audits, and legal counsel on short notice

Built for Defensibility

• Documented due diligence: every decision has a record, a reviewer, and a date
• Verified lab testing: ISO 17025 independent results—no conflicts of interest
• Traceable decisions: supplier → can/coating → lot → determination—fully linked
• Structured system: not ad-hoc—a management system reviewers recognize

Options (Managed Service vs DIY)

• Managed service (Consultare Inc. Group): hands-off compliance execution, expert-managed monitoring, monthly reporting
• DIY (SystemsBuilder): self-managed execution using the same artifact structure

Bottom Line — Your Risk Profile (Canned Food Linings)

• No oral MADL: “zero-detection posture” for bisphenol migration—any detection can trigger enforcement
• Regrettable substitution: BPA → BPS → next; class listing under review captures alternatives
• 2025 enforcement surge: 900+ BPS NOVs (20%+ of notices per brief)
• Strict environment: California’s aggressive private-enforcement regime

Your product is already in a high-risk category—even if you’ve done nothing wrong.
