Import Tips
• Ensure the CMC flakes are in primary form (flakes, powder, granules) and not mixed with other substances that could change classification
• Verify the chemical modification is solely on the cellulose backbone, as graft copolymers would be classified elsewhere
• Keep supplier documentation showing the sodium carboxymethyl cellulose content to support the tariff classification
