4001.21.00.30 - Grade 3

This HTS category, 4001.21.00.30, specifically classifies Grade 3 natural rubber in the form of smoked sheets. This designation applies to natural rubber that has undergone the smoking process to preserve it and has been formed into sheets, falling under the broader group of natural rubber in other forms.

Within the "Smoked sheets" classification, Grade 3 is distinguished from its siblings, Grade 1 (4001.21.00.10) and Grade 2 (4001.21.00.20), primarily by its impurity levels and physical characteristics, which are assessed according to established industry grading standards. Grade 3 rubber typically exhibits a higher acceptable level of non-rubber constituents and potentially minor imperfections compared to the superior grades. The "Other" category (4001.21.00.50) at this level serves as a residual category for smoked sheets that do not meet the specific criteria for Grades 1, 2, or 3.

As this is a leaf node, there are no further subcategories within 4001.21.00.30. Therefore, the classification is definitive for Grade 3 smoked sheets. Importers and exporters should ensure that their product's specifications align with the accepted standards for Grade 3 smoked sheets to ensure accurate customs declarations.
