Import Tips
• Include buffer composition; phosphate buffers common but must not create 'other oxygen function' per heading definition
• FDA registration required for medical device/pathology imports even if classified as chemical
• Small volume retail packs risk reclassification under 3822 if labeled as 'diagnostic reagents'
