Exact quantitative limits under Regulation (EU) 2025/40 Article 5 (Aug 12, 2026)

Art. 5(4): <= 100 mg/kg Heavy Metals Sum

The sum of concentration levels of Lead (Pb), Cadmium (Cd), Mercury (Hg), and Hexavalent Chromium (Cr(VI)) in packaging or homogeneous packaging components must not exceed 100 mg/kg (ppm).

Art. 5(5): 25 ppb & 250 ppb Targeted PFAS

Food-contact packaging cannot be placed on the EU market on or after August 12, 2026 if it contains >= 25 ppb of any single targeted PFAS (non-polymeric) or >= 250 ppb sum of targeted PFAS.

Art. 5(5): 50 ppm Total Fluorine / Polymeric PFAS

Total PFAS including polymeric PFAS in food-contact packaging is capped below 50 ppm (50 mg/kg); if total fluorine exceeds 50 mg F/kg, proof of PFAS vs. non-PFAS fluorine content is required.

EU PPWR Article 5 Substance Restriction Threshold Reference & Unit Conversions

PPWR Provision	Substance Scope	Statutory Threshold	Unit Equivalents Checked by CLI
Article 5(4)	Pb + Cd + Hg + Cr(VI) sum (all packaging)	<= 100 mg/kg	100 ppm == 0.01% w/w per homogeneous component
Article 5(5)(a)	Any single targeted PFAS (food-contact, excl. polymeric)	< 25 ppb	0.025 mg/kg == 25 ug/kg == 0.025 ppm
Article 5(5)(b)	Sum of targeted PFAS (food-contact, w/ precursor step)	< 250 ppb	0.25 mg/kg == 250 ug/kg == 0.25 ppm
Article 5(5)(c)	Total PFAS incl. polymeric PFAS (food-contact)	< 50 ppm	50 mg/kg == 0.005% w/w (Total F > 50 mg/kg triggers proof)

FAQ

Frequently asked questions

Why do supplier lab reports cause unit-conversion errors on PFAS vs. heavy metals?

Heavy metal test reports typically report in mg/kg (ppm), whereas targeted PFAS LC-MS/MS reports often report in ug/kg (ppb) or ng/g. Confusing ppm and ppb creates a 1,000x threshold error—which PackProof normalizes deterministically.

How is 'ND' (Not Detected) handled when summing Pb + Cd + Hg + Cr(VI)?

PackProof checks both lower-bound (ND = 0) and conservative upper-bound (ND = Method Detection Limit / LOQ) sums so compliance engineers immediately spot high-LOQ screening reports that could exceed 100 mg/kg.

Can I automate Article 5 BOM checks in CI/CD or supplier portals?

Yes. Run npx packproof-ppwr-cli ./packaging-bom.json --json in Node.js or use ppwr_art5_threshold_check.py from our $0+ Open Compliance CLI Starter Kit.
