1702.40 - Glucose and glucose syrup, containing in the dry state at least 20 percent but less than 50 percent by weight of fructose, excluding invert sugar:

This HTS classification, 1702.40, specifically covers glucose and glucose syrup that, in their dry state, contain a fructose content of at least 20% but less than 50% by weight. Crucially, this category excludes invert sugar, which is a distinct product. These syrups are derived from starch and are distinct from pure glucose or glucose syrups with lower fructose content.

The key differentiator for 1702.40 lies in its specific fructose percentage range. It is distinct from 1702.30, which encompasses glucose and glucose syrup containing less than 20% fructose or no fructose at all. Furthermore, it is separate from 1702.60, which covers other fructose and fructose syrups with a higher fructose content, exceeding 50% by weight. Chemically pure fructose, classified under 1702.50.00.00, is also a separate designation.

Within this classification, two subcategories exist to further refine the categorization: "Blended syrups described in additional U.S. note 4 to chapter 17" and "Other." The former indicates syrups that have undergone specific blending processes as defined by U.S. trade regulations for this chapter, while the latter serves as a residual category for all other glucose and glucose syrups meeting the 20% to 50% dry-state fructose criteria that do not fall under the specified blended syrup provision.
