4001.22.00.15 - Grade L

This HTS classification covers Grade L of technically specified natural rubber (TSNR). TSNR refers to natural rubber that has been processed to meet specific technical standards beyond general natural rubber classifications, such as precise viscosity, cure characteristics, and physical properties. Grade L is one such specific grade, indicating a particular set of controlled technical specifications that differentiate it from other TSNR grades.

Distinguishing Grade L from its sibling categories is based on its unique technical specifications. For instance, Grade 5, Grade CV, Grade 10, and Grade 20 represent other TSNR grades with their own defined sets of properties, likely differing in parameters like Mooney viscosity, dirt content, or ash content. While all fall under technically specified natural rubber, the "L" designation signifies a distinct formulation or processing outcome that meets particular industry requirements not met by these other grades.

As this node represents a leaf category within the HTS database, there are no further subcategories. Classification at this level is determined by the material meeting the precise technical specifications designated as "Grade L." Importers and exporters should ensure that the natural rubber in question has been certified or documented to meet the specific technical parameters associated with Grade L to ensure accurate customs declaration and avoid potential discrepancies.
