2804.50.00 - Boron; tellurium

This HTS category, 2804.50.00, specifically covers boron and tellurium in their elemental or uncombined forms. These distinct nonmetallic elements are classified here based on their chemical properties and common industrial applications. It is important to note that while they are grouped together, they are separate elements with unique uses.

Unlike the sibling categories that encompass hydrogen, various rare gases, nitrogen, oxygen, and silicon, this classification focuses on the specific properties of boron and tellurium. Boron is a metalloid known for its hardness and use in various alloys, ceramics, and detergents. Tellurium, also a metalloid, is primarily utilized in semiconductors, solar cells, and as an alloying agent for copper and iron.

The subcategories within 2804.50.00.10 and 2804.50.00.20 further refine the classification by separating boron from tellurium. This distinction is crucial for customs purposes, allowing for accurate tracking of trade volumes and application of specific tariffs or regulations associated with each element individually, reflecting their differing market dynamics and supply chains.
