Import Tips
• Document stabilizer type and concentration (<1% typically) to qualify under Chapter Note 1(f) allowances
• Monitor melting point specs (around 40°C) to prevent solid-to-liquid transition during ocean transit
• Declare exact isocyanate content as active ingredient for accurate duty assessment
