Why Get Certified?

✅ Trust & Credibility

Consumers are skeptical of greenwashing. Having third-party certification shows you're legit.

✅ Market Access

Many eco-conscious retailers and platforms (like Etsy, Zalando, or even Amazon’s Climate Pledge Friendly) require certification for eco-products.

✅ Higher Pricing Power

Certified products command premium pricing due to the trust they offer.

✅ Legal Compliance & Export

If you're exporting to the EU or North America, certifications like GOTS or Fair Trade often simplify customs and legal compliance.

3. Step-by-Step: How to Get Certified

Let’s break down the general certification journey:

Step 1: Decide What to Certify

  • Are you certifying the entire brand, a specific product line, or just your manufacturer?

  • For example: If you’re a womens T-shirt manufacturer producing for multiple brands, you may certify your facility.

Step 2: Choose the Right Certification

Ask:

  • Is my fabric organic or recycled? (→ GOTS, OEKO-TEX)

  • Do I ensure fair labor and social responsibility? (→ Fair Trade, SA8000)

  • Is my brand vegan or animal-free? (→ PETA Vegan)

Step 3: Prepare Documentation

Gather:

  • Raw material details (e.g., 100% GOTS organic cotton purchase receipts)

  • Worker contracts & payroll records

  • Waste disposal and chemical use logs

  • Product test results (for OEKO-TEX or GOTS)

Step 4: Contact a Certification Body

Each certification works through authorized agencies. For GOTS, in India, options include:

  • Control Union India

  • ECOCERT India

They’ll send auditors to:

  • Inspect raw material sourcing

  • Audit factory/workshop compliance
