A primary form elastomeric polyurethane pre-polymer resin used in the production of spandex fibers for stretch fabrics. It qualifies under 3909.50.10.00 due to its high polyurethane monomer content (>95% by weight) and inherent elastomeric stretch properties.

Import Tips
• Include detailed monomer analysis certificates showing polyurethane dominance to comply with Chapter 39 polymer classification hierarchy
• Declare as 'primary forms' only if uncompounded; compounded masterbatches may require different classification
• Watch for misdeclaration as finished spandex yarn, which falls under Chapter 54, leading to incorrect duty assessment
