SITCSection 3
U.S. imports of petroleum coke (SITC 33542) totaled $47.3M in April 2026, traded with 31 countries.
Importers of Petroleum Coke paid $11K in duties in April 2026 — an effective duty rate of 11% on $96K in dutiable value, based on actual customs collections rather than the published tariff schedule. Petroleum Coke imports of $47.3M in April 2026 ran 44% above the year-to-date monthly average of $32.8M.
Last updated: April 2026 dataA solid carbon byproduct of crude oil refining, petroleum coke (petcoke) is traded in two commercially distinct forms: green (uncalcined) coke, used as fuel or feedstock, and calcined coke, a critical input for aluminum smelting anodes and graphite electrode production. Sulfur content is the key quality parameter that separates fuel-grade petcoke — typically high-sulfur material burned in cement kilns and power plants — from anode-grade material, which commands a significant premium. Petcoke exports from the US are substantial, but import flows also occur for specific grades not produced domestically.

Anode-grade (low-sulfur, low-metals) calcined petroleum coke is used in aluminum and steel electrode manufacturing and commands a premium over fuel-grade material. Fuel-grade petcoke is typically high-sulfur green coke sold to cement kilns and industrial boilers. While both fall under the same SITC heading, buyers and customs brokers should document the grade and calcination status, as these affect valuation and may influence end-use certificate requirements in certain markets.
Fuel-grade petroleum coke with high sulfur content may be subject to EPA air quality regulations when combusted domestically, and some states impose additional restrictions on its use as a fuel. Import documentation should accurately reflect sulfur content and intended end use. Importers should verify current EPA and state-level requirements before committing to fuel-grade petcoke supply contracts.
