Import Tips

• Provide detailed chemical analysis certificates confirming purity and structure to verify classification under Chapter 29 as a separate chemically defined compound

• Ensure proper HAZMAT documentation (UN 2927 or similar) due to its corrosive and reactive nature; common pitfalls include inadequate spill containment labeling

• Declare exact CAS number (677-43-0) and avoid mixing with stabilizers that could shift it to heading 2929.90.40 for compounds with added preservatives
