9403.20.00.35 - Mechanically adjustable bed or mattress base, not foldable, having the characteristics of a bed or bed frame, of a width exceeding 91.44 cm, of a length exceeding 184.15 cm, and of a depth exceeding 8.89 cm

This HTS category, 9403.20.00.35, specifically covers mechanically adjustable bed or mattress bases. These items are designed to alter their elevation or configuration through mechanical means and are not foldable. Crucially, they must possess the essential characteristics of a bed or bed frame, evidenced by meeting specific dimensional thresholds: a width exceeding 91.44 cm, a length over 184.15 cm, and a depth greater than 8.89 cm. This classification is for products that provide support for a mattress and offer adjustable functionality beyond a simple stationary frame.

It is important to distinguish this category from its siblings. Unlike sibling categories such as cribs or toddler beds (9403.20.00.16 and 9403.20.00.17), this code applies to adult bedding bases. It also differs from stationary mattress bases (9403.20.00.40) by the presence of mechanical adjustability. Furthermore, it is distinct from foldable mattress foundations (indicated by the empty sibling category) as this classification is for non-foldable items. The "Other" category (9403.20.00.50) serves as a residual for metal furniture not otherwise specified.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, classification within 9403.20.00.35 is determined by the direct presence of the described features: mechanical adjustability, non-foldable nature, bed/bed frame characteristics, and adherence to the specified minimum dimensions. Examples would include electric bed frames with remote-controlled adjustments for head and foot elevation, or hand-crank adjustable bases meeting the size criteria, provided they are constructed of metal.
