U.S. exports of Coke and Semicoke of Coal, Lignite, or Peat; Retort Carbon (HS 270400) totaled $41.6M in August 2026.
Last updated: August 2026 dataCoke produced by high-temperature carbonization of coal is a critical reductant and structural support material in blast furnace ironmaking, making this heading strategically important to the US steel industry. The US schedule subdivides the heading into fuel-grade coke (2704000010), large-lump blast furnace coke above 100mm retained on a 100mm sieve (2704000011), non-fuel industrial coke (2704000020), residual coal coke (2704000025), and coke or semicoke derived from lignite or peat plus retort carbon (2704000050). Canada leads import supply, with Czech Republic, Italy, South Africa, and Colombia also contributing — a geographically diverse supplier base that reflects the global nature of metallurgical coke procurement. Buyers should note that the size-grading distinction in line 2704000011 is a physical specification requirement, not merely a commercial grade, and must be documented to support classification.

Line 2704000011 requires that the coke have a diameter greater than 100mm and that 50% or more be retained on a 100mm sieve — a measurable physical specification. Importers should retain sieve analysis certificates from the producer or an independent laboratory as supporting documentation, since CBP may request evidence that the size threshold is met.
Retort carbon is a dense carbonaceous deposit that forms on the walls of gas retorts during coal distillation, distinct from the porous, formed coke produced by coking ovens. Both are captured under heading 2704, with retort carbon grouped alongside lignite and peat coke in line 2704000050. The key classification question is whether the material is a formed coke product or a retort deposit, which affects which 10-digit line applies.
