What is FSC Certification

FSC certification, issued by the Forest Stewardship Council (FSC), is the global standard for identifying paper and packaging made from responsibly managed forests. Products that carry FSC labels or display the FSC logo verify that every step of the supply chain meets strict environmental, social, and economic criteria.

FSC-certified forest showing sustainable logging practices

Founded in 1993, the FSC created independent standards for forest management and Chain of Custody (CoC) traceability, ensuring materials remain verifiable from forest to final product. Today, FSC certification is recognized worldwide as the benchmark for responsible forestry and sustainable packaging.

FSC Chain of Custody (CoC) Certification

FSC Chain of Custody (CoC) certification is what connects responsible forestry practices to finished packaging. It verifies that materials from FSC-certified forests are tracked, documented, and kept separate from non-certified sources at every stage of production, from the forest to the final box.

In other words, while FSC Forest Management certification ensures that trees are harvested responsibly, FSC CoC certification ensures the integrity of that claim as materials move through the supply chain.

The CoC system follows each batch of certified material through these key stages:

  1. Forest – Raw fiber is harvested from responsibly managed, FSC-certified forests
  2. Paper Mill – Wood pulp is processed into paper, kraft liner, or medium with verified traceability
  3. Corrugated Manufacturing – Certified paper is combined into liner and fluting structures under an FSC-controlled production system
  4. Conversion – FSC-certified sheets are die cut, printed, and glued into finished packaging while maintaining identity separation
  5. Supplier or Wholesaler – Finished FSC-certified packaging is distributed or sold under an approved FSC Chain of Custody certificate number

For brands, this chain of documentation is what allows an FSC logo to appear on your packaging. Every entity that takes legal ownership or transforms the material must hold an active CoC certificate or be covered under a certified partner’s scope.

💡 Tip: If your company doesn’t have its own FSC certification, you can still produce FSC-labeled packaging through GreenDot’s CoC. However, you’ll need a separate promotional license to use FSC trademarks in marketing or advertising.

FSC Claim Types and Their Typical Uses

FSC-certified materials are categorized by how their fibers are sourced and verified. Each FSC certification claim type – 100%, Recycled, or Mix – has different performance, cost, and sustainability implications depending on the end use.

Types of FSC Certification Marks

FSC 100%

Made entirely from virgin wood pulp sourced from responsibly managed FSC-certified forests. This pulp contains long, strong fibers, providing superior mechanical strength and brightness.

Characteristics:

Common Uses:

FSC Recycled

Composed of 100% recycled fiber, this grade minimizes environmental impact but uses shorter fibers that reduce strength and surface uniformity.

Characteristics:

Common Uses:

FSC Mix

Made from a combination of FSC 100%, FSC Recycled, and controlled wood (non-certified but verified to avoid illegal or controversial sources). It offers the best balance of strength, cost, and appearance for most packaging applications.

How FSC Mix Applies to Corrugated Packaging:

In a standard corrugated sheet, there are three layers:

  1. Liner 1 (Outer Liner): Requires high burst strength and print surface quality, so it often uses FSC 100%, FSC Mix, or occasionally non-FSC virgin material.
  2. Fluting (Medium): Provides compressive strength (ECT) but not burst strength, allowing the use of FSC Recycled pulp.
  3. Liner 2 (Inner Liner): Usually similar to the outer liner but may be downgraded slightly depending on product and strength needs.
Corrugated layer makeup

This combination – FSC Mix for liners and FSC Recycled for the fluting – is the most common and practical structure for retail-ready and transport packaging. It meets strength and sustainability targets while maintaining competitive cost.

How to Use FSC Labels on Products

To display an FSC label legally, several design and formatting rules apply.

1. Required Elements

Each approved FSC label must include:

FSC Logo breakdown

2. Size and Layout

logo minimum sizes and usage guidelines

3. Color Specifications

logo color specification usage guidelines

4. Common Misuses to Avoid

Consistent, correct usage preserves the credibility of your certification and avoids audit failures.

Using FSC Logos

The FSC logo and related trademarks (e.g., the tree-checkmark symbol and “Forest For All Forever”) are protected assets governed by FSC’s trademark rules. Understanding where and how you can use them is critical to staying compliant.

Using FSC Logos on Product Packaging

If your product packaging uses FSC-certified materials, you may apply the appropriate FSC label (100%, Recycled, or Mix) once the artwork is reviewed and approved under your supplier’s Chain of Custody certificate.

Approval Process Overview:

  1. Apply for or confirm your FSC license (or use GreenDot’s CoC if applicable).
  2. Verify that all materials in your product meet FSC certification requirements.
  3. Add the correct FSC trademark and label according to official specifications.
  4. Submit the artwork for approval via the FSC online portal.
  5. Receive confirmation and begin printing or production.

At GreenDot, artwork approvals typically take 2–3 business days per SKU once submitted to FSC.

Using FSC Logos for Marketing or Promotion

Brands that want to reference FSC certification outside of packaging, such as on websites, brochures, catalogs, or social media, must hold an FSC Promotional License. This license ensures the messaging, imagery, and logo usage meet FSC’s communication standards.

If you’re not certified but purchase FSC-labeled packaging through GreenDot’s CoC, you can:

Why Artwork Approval Matters

Incorrect or unauthorized FSC certification logo use can result in compliance violations or suspended certification. Submitting your artwork through the FSC approval portal ensures:

💡 GreenDot helps clients prepare and submit FSC artwork for review, ensuring your label complies with current FSC guidelines before production.

How to Verify an FSC Label Is Genuine

Because FSC certification marks are globally recognized, counterfeit labels occasionally appear. Fortunately, all legitimate FSC-certified products are traceable to the source.

Each genuine FSC certification label includes a trademark license code (e.g., FSC® CXXXXXX). You can verify authenticity by entering this code on the official FSC certificate database to confirm:

If the code or company cannot be found, the label may be fraudulent or expired.

Key Takeaway

For packaging and print suppliers, FSC certification is more than a logo, it’s a global symbol of accountability and sustainability. Using FSC materials and labeling them correctly ensures your products align with retailer and brand expectations while protecting the world’s forests for future generations.
