**A Technical Reference for Procurement Managers, Sustainability Directors, and Product Engineers**

—

## Executive Summary

The Global Recycled Standard (GRS) certification has become a de facto requirement for post-consumer recycled (PCR) resin suppliers serving the European and North American packaging markets. As of Q1 2025, over 1,800 facilities worldwide hold GRS certification, with PCR plastics accounting for approximately 62% of all certified material output. The certification process requires 4–8 months from application to final approval, with costs ranging from €8,000 to €25,000 depending on facility complexity and certification body selection.

This guide provides a technical roadmap for PCR suppliers seeking GRS certification, covering application procedures, chain of custody requirements, chemical restrictions, and practical strategies for maintaining compliance under evolving regulatory frameworks including the EU’s Packaging and Packaging Waste Regulation (PPWR) and the Carbon Border Adjustment Mechanism (CBAM).

## Section 1: Understanding GRS Certification Requirements

### 1.1 Scope and Applicability

The GRS certification, administered by Textile Exchange, applies to any product containing at least 20% recycled content. For PCR plastics, the standard requires:

– **Minimum recycled content**: 50% for GRS-labeled products (20% for GRS-certified materials without product label)
– **Chain of custody**: Full transaction verification from collection to final product
– **Chemical restrictions**: Compliance with REACH SVHC candidate list and GRS prohibited substances list
– **Environmental management**: Documented environmental policy and monitoring systems
– **Social compliance**: ILO core labor standards adherence at all processing facilities

### 1.2 Key Differences from Alternative Certifications

**Key insight**: GRS provides the most comprehensive verification but requires the highest operational investment. For PCR suppliers targeting EU packaging markets under PPWR, GRS combined with ISCC PLUS offers maximum regulatory flexibility.

## Section 2: Pre-Application Preparation

### 2.1 Material Sourcing Documentation

Before initiating the GRS application, suppliers must establish auditable documentation for PCR feedstock:

**Required documentation for each feedstock source**:
1. Supplier recycling facility license and permits
2. Material characterization reports (polymer type, contamination levels, moisture content)
3. Waste origin documentation (post-consumer vs. post-industrial verification)
4. Transportation records with mass balance calculations
5. Supplier GRS or equivalent certification (if applicable)

**Technical note**: For PCR plastics, the standard requires a minimum of 95% post-consumer content in the feedstock to qualify as PCR. Mixed post-industrial/post-consumer streams require separate mass balance tracking.

### 2.2 Facility Readiness Assessment

Conduct a pre-audit gap analysis covering:

### Step 4: Non-Conformity Resolution

Typical non-conformities and resolution strategies:

**Critical non-conformities** (require immediate correction before certification):
– No segregation system: Install physical barriers and separate storage
– Chain of custody breakdown: Implement transaction certificate system
– Chemical non-compliance: Remove restricted substances or reformulate

**Major non-conformities** (must be corrected within 90 days):
– Incomplete mass balance records: Implement digital tracking system
– Missing supplier certifications: Obtain within 30 days
– Inadequate training: Conduct GRS awareness program

**Minor non-conformities** (correct within 6 months):
– Documentation formatting issues
– Non-critical chemical inventory gaps
– Environmental monitoring improvements

### Step 5: Certification Issuance

Upon successful resolution of all non-conformities:

– **Certificate validity**: 1 year from issue date
– **Scope certificate**: Covers facility and product categories
– **Transaction certificates**: Required for each shipment to certified customers
– **Label approval**: Submit product label designs for Textile Exchange approval

**Timeline summary**:
– Application to audit: 4–8 weeks
– Audit duration: 2–3 days
– Non-conformity resolution: 30–90 days
– Total process: 4–8 months

## Section 4: Technical Requirements for PCR Plastics

### 4.1 Quality Specifications

GRS certification requires documented quality control procedures. For PCR plastics, the following parameters must be monitored:

**Mechanical properties** (per ASTM or ISO standards):
– Tensile strength at yield: Minimum 80% of virgin specification
– Flexural modulus: Within 15% of virgin specification
– Notched Izod impact: Minimum 70% of virgin specification
– Heat deflection temperature: Within 10°C of virgin specification

**Processing parameters**:
– MFR consistency: ±15% across production batches
– Moisture content: <0.2% for most thermoplastics
– Contamination: <0.5% non-target polymer, 5.0 | 1.2–1.8 | 50–100% |
| Film (LDPE) | 0.3–0.8 | >8.0 | 1.0–1.5 | 30–80% |
| Injection molding (PP) | 10–30 | >3.0 | 1.5–2.2 | 30–70% |
| Pipes (HDPE) | 0.2–0.5 | >10.0 | 1.0–1.5 | 20–50% |

### 4.2 Chemical Compliance

GRS requires compliance with:
– **REACH SVHC candidate list** (currently 235 substances)
– **GRS Prohibited Substances List** (updated annually)
– **EU POP Regulation** (persistent organic pollutants)

**Testing requirements**:
– SVHC screening: Annually or when formulation changes
– Heavy metals: Quarterly (Pb, Cd, Hg, Cr VI)
– Phthalates: Annually for flexible PVC products
– PFAS: Annually for any material with potential contamination

**Practical recommendation**: Implement a chemical management system that tracks all additives, processing aids, and cleaning agents. Maintain a “positive list” of approved chemicals with corresponding REACH registration numbers.
