Rates from the U.S. Harmonized Tariff Schedule (USITC, saved 2026-10-26). The normal rate is column 1 general; column 2 applies to countries without normal trade relations. A range means different products under the code have different rates.

Duty collected is Census's calculated duty on imports for consumption. Figures cover every 10-digit product under the code, so they can include goods beyond this mineral, and the duty shown is not split into Section 232, Section 301 or antidumping duties. Bars show the largest code for each direction. Group rows such as the EU or OECD are left out so no country is counted twice.

Value chain and risk

Where in the chain the bottlenecks sit, and what other governments and sources say about supply risk.

Value chain: where the bottlenecks are

Mining

Arsenic is obtained from smelter flue dust or by roasting arsenopyrite, and has been recovered from orpiment and realgar in China, Peru and the Philippines and from copper-gold ores in Chile. (U.S. role not stated)

The source says
“Arsenic may be obtained from copper, gold, and lead smelter flue dust, as well as from roasting arsenopyrite, the most abundant ore mineral of arsenic.”
“Arsenic has been recovered from orpiment and realgar in China, Peru, and the Philippines and from copper-gold ores in Chile”

Source: USGS Mineral Commodity Summaries 2026, Arsenic (PDF page 48) (2026-02)

Ore processing and primary recovery

No arsenic was recovered from nonferrous smelter residues and dusts in the United States, while Morocco makes arsenic trioxide from cobalt-arsenide ore of the Bou Azzer mine. (no U.S. activity)

The source says
“No arsenic was recovered domestically from arsenic-containing residues and dusts generated at nonferrous smelters in the United States.”
“Arsenic trioxide was produced at the hydrometallurgical complex of Guemassa, near Marrakech, Morocco, from cobalt-arsenide ore from the Bou Azzer mine.”

Source: USGS Mineral Commodity Summaries 2026, Arsenic (PDF page 48) (2026-02)

Refining and separation bottleneck

The United States has not produced arsenic trioxide or primary arsenic metal since 1985; Peru, China and Morocco make more than 95% of the world's arsenic trioxide. (no U.S. activity)

The source says
“Arsenic trioxide and primary arsenic metal have not been produced in the United States since 1985.”
“Peru, China, and Morocco, in descending order of production, continued to be the leading global producers of arsenic trioxide, accounting for more than 95% of estimated world production in 2025.”

Source: USGS Mineral Commodity Summaries 2026, Arsenic (PDF page 48) (2026-02)

Metal, alloy and chemical bottleneck

China supplied more than 80% of U.S. arsenic trioxide imports and more than 90% of arsenic metal imports through July 2025. (no U.S. activity)

The source says
“China supplied more than 80% of United States imports of arsenic trioxide and more than 90% of arsenic metal imports through July 2025.”

Source: USGS Mineral Commodity Summaries 2026, Arsenic (PDF page 48) (2026-02)

Components and end use

High-purity arsenic metal goes into gallium-arsenide semiconductors for solar cells, space research and telecommunications. (U.S. role not stated)

The source says
“High-purity (99.9999%) arsenic metal was used to produce gallium-arsenide (GaAs) semiconductors for solar cells, space research, and telecommunications”

Source: USGS Mineral Commodity Summaries 2026, Arsenic (PDF page 48) (2026-02)

Recycling

No arsenic was recovered domestically from smelter residues and dusts; only new scrap from GaAs manufacturing was recycled. (no U.S. activity)

The source says
“Arsenic metal was contained in new scrap recycled during GaAs semiconductor manufacturing.”
“No arsenic was recovered domestically from arsenic-containing residues and dusts generated at nonferrous smelters in the United States.”
