Import Tips
• Ensure that thiourea and formaldehyde monomers together exceed 95% by weight of the resin to qualify for this tariff item
• Keep the resin in primary form (powder, granules, or liquid) and avoid any further processing that could change its classification
• If the resin contains additives such as fillers or plasticizers exceeding 1% by weight, verify whether it still meets the definition of a 'composition' under supplementary note 2
