If you are an importer of polyester fibers, one of the critical elements you must verify is international certification.
International certifications represent quality and reliability, significantly enhancing a buyer’s market competitiveness. In this post, we introduce four major international certifications beneficial for polyester fiber buyers.
1. OEKO-TEX® Standard 100

OEKO-TEX® Standard 100 is an international standard certifying that textile products are free from harmful substances.
Products certified by OEKO-TEX ensure that the fibers are safe for human use, increasing consumer trust. This certification is particularly important for textiles in close contact with the skin, significantly enhancing consumer preference.
2. GRS (Global Recycled Standard)

The GRS certification verifies that fiber products are made from recycled materials. With growing global interest in environmental protection and sustainability, polyester products with GRS certification become highly attractive to importers. It is especially recommended for companies aiming to build an eco-friendly brand image.
3. ISO 9001 (Quality Management System)

ISO 9001 is an international standard for Quality Management Systems (QMS), evaluating a company's capability to systematically manage and maintain consistent quality in its products and services.
Manufacturers holding ISO 9001 certification gain trust due to their rigorous quality control and enhanced customer satisfaction. Although not legally mandatory, ISO 9001 is an essential evaluation criterion for competitiveness and global trade.
4. REACH Compliance

REACH is the European Union’s regulation for managing chemical substances, encompassing the registration, evaluation, authorization, and restriction of chemicals imported into Europe.
For polyester fibers typically imported as finished products, registration is generally not required. However, if products contain Substances of Very High Concern (SVHC), compliance verification and information provision are necessary.
Importers entering the EU market must ensure REACH compliance to minimize legal risks and secure consumer confidence.
International certifications and regulatory compliance do not only guarantee product quality; they also streamline the import process and enhance brand credibility.
