Import Tips & Compliance
• Provide precise OD/ID measurements; capillary tubes often scrutinized for 'hollow profile' vs tube distinction
• Chemical composition certs essential for 316L to prevent duty hikes if deemed other steel
• Avoid bulk packaging mimicking rods; retail coiled packaging supports tube classification
