9902.12.66 - Plaiting materials and products of plaiting materials, suitable for use in window shades, presented in rolls each having an area measuring 27.85 m2 or more but not over 46.46 m2, of bamboo reeds and/or bamboo slats each measuring 1 mm or more but not over 13 mm in width and/or bamboo cane measuring over 2 mm but not over 5 mm in cross section, the foregoing woven with yarn of polyester into a repeating pattern, such pattern whether or not including grass, paper strips or jute (provided for in subheading 4601.92.20)

This HTS classification, 9902.12.66, pertains to specialized plaiting materials and products derived from them, specifically manufactured for use in window shades. The key defining characteristics include their presentation in rolls meeting specific area requirements (27.85 m² to 46.46 m²) and their composition. The materials must be made from bamboo reeds and/or bamboo slats, with specific width constraints (1 mm to 13 mm), and/or bamboo cane with defined cross-sectional dimensions (over 2 mm to 5 mm). Furthermore, these bamboo components must be woven with polyester yarn, forming a repeating pattern that may optionally include grass, paper strips, or jute, provided the primary material remains bamboo and the weaving process follows the stipulations of subheading 4601.92.20.

Distinguishing this category from its numerous siblings under Chapter 99 is its highly specific nature as a temporary or provisional classification. Unlike the broader commodity classifications found in earlier chapters (e.g., live animals, agricultural products), Chapter 99 codes are typically utilized for goods subject to specific trade agreements, temporary modifications, or additional import restrictions. This particular code signifies a narrowly defined product that has likely been subject to special tariff treatment or regulatory requirements beyond the standard HTS framework.

As a leaf node, HTS code 9902.12.66 does not have further subdivisions. This means that any product meeting the exact material, construction, presentation, and area specifications detailed in its description falls directly into this category. Classification professionals will rely on precise measurement and verification of the physical attributes of the imported goods to ensure accurate application of this code, understanding that it represents a specific, temporary trade provision rather than a general product group.
