The data indicates a continuous decline in the US usage of lead for other oxides, falling from 7.96 thousand metric tons in 2015 to 3.49 thousand metric tons in 2019. This demonstrates a significant reduction in usage, with year-on-year declines observed throughout this period. The compound annual growth rate (CAGR) reflects an average annual decrease in usage over these years.

Future trends to monitor include:

Technological advancements that could reduce lead oxide dependency.
Regulatory policies aimed at limiting lead usage due to environmental concerns.
Innovations in alternative materials that might supplant lead in various applications.
