HS Code 2804.61 – Silicon; containing by weight not less than 99.99% of silicon
HS code 2804.61 is the 6-digit subheading for silicon, containing by weight not less than 99.99% of silicon. It is used for polycrystalline silicon, monocrystalline silicon ingots, silicon wafers (unprocessed), solar-grade silicon and electronic-grade silicon.
What HS 2804.61 covers
This HS code covers high-purity silicon, specifically material with a silicon content of 99.99% or more. This ultra-pure silicon is the bedrock of the semiconductor industry, essential for manufacturing integrated circuits, microprocessors, and solar cells. Its exceptional purity is critical for electronic performance, as even trace impurities can significantly alter electrical properties. Major importers are countries with robust electronics manufacturing and solar panel industries, including Taiwan, South Korea, Japan, China, and the United States. Exporters are typically countries with advanced metallurgical and chemical processing capabilities, such as China, Germany, and the United States. Key aspects of trade include stringent quality control, certification of purity levels, and the high capital investment required for production facilities. The global demand for this material is directly tied to the growth of consumer electronics, data centers, and renewable energy initiatives, making it a strategically important commodity.

Codes often confused with 2804.61
Common mistake. This code is often confused with lower-purity silicon under 2804.69, or with silicon in primary forms for metallurgical use (e.g., ferrosilicon in 7202.2x), but the key differentiator is the "not less than 99.99%" purity threshold.
Top exporters and importers of HS code 280461, 2025
In 2025, the largest exporter of HS code 280461 in UN Comtrade data was the United States, with 32% of world exports; the largest importer in UN Comtrade data was Japan, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

What are common misclassifications for HS code 280461?
This code is often confused with lower-purity silicon under 2804.69, or with silicon in primary forms for metallurgical use (e.g., ferrosilicon in 7202.2x), but the key differentiator is the "not less than 99.99%" purity threshold.
Which countries are the top exporters of goods under HS code 280461?
In 2025, the top exporters of HS code 280461 in UN Comtrade data were the United States ($949M, 32% of world exports), Germany ($886M) and China ($379M). World exports came to about $3.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
