SVHC Substance of Very High Concern

regulation

Chemical substances identified under REACH regulation as posing serious threats to human health or environment, requiring authorization for use in concentrations above 0.1% w/w.

In Simple Terms

SVHCs are chemicals that European authorities have flagged as particularly dangerous due to cancer-causing properties, reproductive toxicity, or environmental persistence. When these substances appear in plastic resins above 0.1%, suppliers must notify customers and may need special authorization to use them.

Why It Matters

SVHC compliance affects resin sourcing, customer notifications, and market access in Europe. Non-compliance can result in supply chain disruptions, legal penalties, and loss of business. Resin traders must track SVHC content in products and maintain updated documentation.

Technical Details

The SVHC Candidate List is updated biannually by ECHA, currently containing over 230 substances. Once a substance reaches the Authorization List (Annex XIV), its use requires specific authorization with sunset dates. Companies must demonstrate adequate control or that socio-economic benefits outweigh risks. Notification obligations trigger at 0.1% concentration threshold per article.

Real-World Examples

Resin supplier notification requirements

A PP supplier discovers their antioxidant package contains 0.15% of an SVHC substance and must immediately notify all customers in writing, providing safe use information and potential substitutes.

Authorization application process

A flame retardant manufacturer applies for SVHC authorization 18 months before the sunset date, submitting a chemical safety report and analysis of alternatives costing over €500,000.

Supply chain impact assessment

An injection molder sources alternative PVC stabilizers after learning their current supplier's product contains SVHC substances that will require authorization, affecting long-term availability and pricing.
