ISO 16373 Testing of Azo Dyes in Textile Trade
The ISO 16373 standard is a critical tool for ensuring the safe and compliant export of textiles containing azo dyes. This service focuses on testing textile products to meet regulatory requirements, particularly in the context of international trade.
Azo dyes are widely used in the textile industry due to their excellent fastness properties and affordability. However, certain azo compounds can break down into aromatic amines upon washing or processing, some of which may be classified as carcinogens under strict regulatory frameworks like REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals).
ISO 16373 provides a method for determining the presence and concentration of azo dyes that can potentially degrade into aromatic amines in textile products. This is crucial for ensuring compliance with trade regulations, particularly in markets like the European Union (EU) where stringent chemical restrictions are enforced.
The testing process involves sample preparation, extraction, and analysis using spectrophotometric methods to identify azo dyes that may release harmful amines under specified conditions. Compliance with this standard is not only important for meeting regulatory requirements but also for maintaining consumer confidence in the safety of exported textiles.
Our laboratory uses state-of-the-art analytical equipment and follows strict protocols to ensure accurate and reliable results. This service ensures that textile products meet international standards, thereby facilitating smooth trade processes without compromising on quality or safety.
The importance of this testing cannot be overstated in the global market. Compliance with ISO 16373 is a key factor in avoiding costly recalls and penalties, ensuring product integrity, and maintaining a positive reputation in the international textile industry.

Scope and Methodology
The scope of ISO 16373 testing includes the identification and quantification of azo dyes in textile products that could potentially release aromatic amines under standard washing conditions. This service ensures compliance with international regulations, particularly those outlined in REACH.
The methodology involves several key steps:
- Sampling: Representative samples are collected from the textiles to be tested.
- Preparation: Samples undergo sieving and dissolution in appropriate solvents.
- Extraction: Extraction is performed using an aqueous solution followed by filtration.
- Analysis: Spectrophotometric analysis quantifies the azo dyes present.
Benefits
Compliance with ISO 16373 offers numerous advantages:
- Avoidance of costly recalls and penalties due to non-compliance.
- Enhanced consumer confidence in the safety of exported textiles.
- Facilitation of smooth trade processes without interruptions from regulatory issues.
- Maintenance of a positive reputation within the international market.
International Acceptance and Recognition
The ISO 16373 standard is widely accepted in international trade, particularly in markets with stringent chemical regulations. Compliance ensures that textile products meet the safety standards required by regulatory bodies like the European Chemicals Agency (ECHA) under REACH.
Our laboratory’s rigorous testing process and adherence to ISO 16373 are recognized by major importers and exporters worldwide, ensuring a seamless export process. Compliance with this standard is essential for maintaining market access in key regions such as the EU, USA, and Asia.
The recognition of our test results across these markets underscores the importance of accurate and reliable testing to meet international standards.
