4001.29.00.00 - Other 🖩

This HTS classification, 4001.29.00.00, encompasses natural rubber in primary forms or in plates, sheets, or strip, that does not fall under the more specific categories of smoked sheets or technically specified natural rubber. It serves as a residual category for various forms of natural rubber not otherwise defined.

This category is distinguished from its siblings, 4001.21.00 (Smoked sheets) and 4001.22.00 (Technically specified natural rubber), by its lack of specific processing or grading criteria. Smoked sheets are characterized by their drying and smoking process, imparting a distinct color and handling property. Technically specified natural rubber (TSNR) is a standardized grade of natural rubber that meets precise technical specifications for properties such as viscosity, purity, and dirt content, often produced through specific chemical and mechanical treatments.

Since 4001.29.00.00 is a leaf node, there are no further subcategories. Therefore, its coverage includes other forms of natural rubber, such as naturally occurring latex (when not in primary forms, but still under 4001 and not specifically handled elsewhere), or forms of rubber that have undergone treatments not sufficient to classify them as TSNR or result in smoked sheets. Examples might include raw, unsmoked sheets that do not meet the criteria for TSNR, or certain forms of coagulated latex that are not otherwise specified. Classification into this category relies on the absence of defining characteristics of the preceding subheadings within the 4001.2x range.
