7013.42.30.00 - Valued over $3 but not over $5 each

This classification pertains to glassware specifically designed for table or kitchen use, excluding items made from glass-ceramics. The defining characteristic of this category is the material composition: it must be glass exhibiting a linear coefficient of expansion not exceeding 5 x 10^-6 per Kelvin within a temperature range of 0°C to 300°C. This technical specification refers to glass with low thermal expansion properties, often associated with specialized glass types that are less prone to cracking or breaking under temperature fluctuations, commonly found in cookware or laboratory glassware.

The distinction between this category and its siblings lies solely in the per-unit value. While all items share the same material and usage characteristics, 7013.42.30.00 specifically covers glassware valued at over $3 but not exceeding $5 per individual item. This contrasts with 7013.42.20.00, which applies to items valued at $3 or less, and 7013.42.40.00, which applies to items valued over $5.

As this is a leaf node within the HTS, there are no further subcategories to explore. Therefore, correct classification under this code relies on confirming the glassware's suitability for table or kitchen purposes, its composition of low-expansion glass as defined, and its precise per-unit value falling within the specified $3 to $5 range.
