4001.21.00.20 - Grade 2

This HTS category, 4001.21.00.20, specifically classifies "Grade 2" of natural rubber in smoked sheet form. Smoked sheets are a primary form of natural rubber produced by coagulating latex, then processing it through sheeting mills and smoking it in a smokehouse. This process reduces moisture content and provides a degree of preservation and distinct visual characteristics.

Grade 2 smoked sheets are distinguished from other grades by their specific physical and chemical properties, which are typically defined by industry standards. While Grade 1 smoked sheets (4001.21.00.10) represent a higher quality with fewer impurities and defects, Grade 2 represents a product meeting certain acceptable tolerances for these characteristics, making it suitable for a range of industrial applications. Conversely, Grade 3 smoked sheets (4001.21.00.30) may have more lenient specifications compared to Grade 2. The "Other" category (4001.21.00.50) would encompass any smoked sheets that do not meet the criteria for Grades 1, 2, or 3.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification within this code depends entirely on meeting the specific grading criteria for "Grade 2" smoked sheets, as determined by the relevant industry specifications and potentially by customs authorities upon import. This detailed classification ensures that natural rubber products are accurately identified for tariff and statistical purposes.
