Import Tips & Compliance
• Provide certificate of analysis confirming chemical purity and D-arabinose identity to avoid reclassification as general sugars
• Ensure proper labeling with CAS number (5328-37-0) and purity percentage for FDA and customs verification
• Declare as research chemical only; avoid health claims to prevent scrutiny under pharmaceutical regulations
