4601.21 - Of bamboo:

This category, HTS 4601.21, specifically encompasses articles and products manufactured from bamboo, which are then formed into plaits, woven sheets, or assembled into strips. These goods, falling under the broader scope of manufactures of plaiting materials, are characterized by their primary construction material being bamboo, processed and manipulated for various applications. This includes, but is not limited to, mats, matting, screens, and other finished or partly finished articles that utilize the plaiting or weaving properties of bamboo.

It is crucial to distinguish this category from its siblings. HTS 4601.22 covers similar plaited or woven articles made specifically from rattan, a different type of flexible vine. The "Other" category, HTS 4601.29, serves as a residual classification for articles of plaiting materials that are neither exclusively of bamboo nor rattan, encompassing a wide array of other natural fibers and materials.

Within this bamboo-specific category, further distinctions are made to refine classification. Subcategory 4601.21.40.00 addresses items that are explicitly woven or have been partly assembled into strips, highlighting the construction method. The remaining subcategories within 4601.21 are designated for "Other" bamboo articles, suggesting that any bamboo-based plaiting, weaving, or assembled product not falling under the "woven or partly assembled" designation will be classified here, offering a comprehensive classification for all bamboo plaits and similar products.
