Import Tips
• Verify the CMC is in flake form and not further processed into articles, as that would change the tariff classification
• Declare the exact viscosity grade and purity to support the technical-grade designation
• If the CMC is blended with other polymers, check whether it still qualifies as a single polymer under the subheading note
