Import Tips

• Provide detailed chemical analysis (NMR, MS) confirming the 4,7-dichloroquinoline structure to avoid misclassification as other quinolines

• Include Safety Data Sheets (SDS) and purity certificates (>98%) as documentation for customs, especially for REACH/ TSCA compliance

• Avoid common pitfalls like insufficient impurity disclosure, which can trigger FDA scrutiny for pharmaceutical intermediates
