📌 Tip: Always verify that the grade of Didecyl Dimethyl Ammonium Chloride (DDAC) matches your intended use and complies with your target market’s regulatory requirements.

Regulatory and Compliance Considerations

For international buyers, regulatory compliance is essential when purchasing DDAC. Below are key guidelines:
