Import Tips

• Verify chemical purity and provide Certificate of Analysis (CoA) confirming it meets 'chemically defined' criteria per Chapter 28 Note 1 to avoid reclassification

• Ensure SDS includes proper hazard labeling as it's a reducing agent; common pitfall is insufficient documentation leading to holds at port

• Check for stabilization with organic substances as required; unstabilized forms may shift to other sulfoxylate subheadings
