1102 - Cereal flours other than of wheat or meslin:

This HTS category, 1102, encompasses cereal flours that are *not* derived from wheat or meslin (a mixture of wheat and rye). This includes flours made from a variety of other grains, such as corn (maize), rice, barley, rye, oats, and buckwheat, when processed into a flour form. The primary characteristic is the milling of these specific cereals into a powdery substance used for food production or other industrial purposes.

When classifying within Chapter 11, it's crucial to distinguish this category from those covering wheat or meslin flours. While siblings at the root level of the HTS represent entirely different product groups like live animals, the immediate distinctions within Chapter 11 revolve around the source cereal. For instance, flours made solely from wheat would fall under a separate HTS heading within Chapter 11, not here.

This category is further detailed by subheadings that specify the type of cereal flour. The most prominent subdivision is for corn (maize) flour, acknowledging its widespread use. Other flours not specifically enumerated are captured under the "Other" subheading, requiring careful consideration of the origin cereal to ensure correct classification based on the material composition and processing.
