9902.12.03 - Belting, for machinery, of plastic, containing textile components, in which man-made or vegetable fiber do not predominate by weight over any other textile fiber, of a width exceeding 120 cm, but not more than 171 cm (provided for in subheading 3926.90.59)

This HTS category, 9902.12.03, specifically classifies certain types of industrial belting made from plastic. The key defining characteristics for goods falling under this provision are their construction, which must include textile components where man-made or vegetable fibers do not outweigh any other textile fiber by weight. Furthermore, the belting must be of a width exceeding 120 cm, but not more than 171 cm. This classification is a temporary provision, reflecting modifications to standard tariff treatments under trade agreements or specific agricultural adjustment acts.

Unlike general plastic goods or broader belting categories found elsewhere in the HTS, this provision is highly specific. It focuses on plastic belting with a particular textile composition and a defined, relatively wide dimension. This ensures that only precisely described industrial belting is subject to the temporary measures associated with Chapter 99. Standard belting that doesn't meet these precise material or dimensional criteria would be classified under different, more general HTS headings.

As this HTS code is a leaf node, it has no further subcategories. Therefore, classification under 9902.12.03 depends entirely on meeting all the described criteria. Importers must carefully verify the material composition, specifically the relative weight of textile fibers, and confirm the exact width of the belting to ensure correct classification. The parent context within Chapter 99 highlights that these are temporary measures, requiring close attention to any associated directives or rulings that might affect the classification or duty treatment.
