Coal (Other Than Anthracite or Bituminous), Not Agglomerated

Sub-bituminous coal and other residual non-agglomerated coal grades that do not qualify as anthracite or bituminous are captured here, with the US schedule providing dedicated lines for sub-bituminous coal (2701190010) and a catch-all for remaining types (2701190050). Sub-bituminous coal occupies a middle rank between lignite and bituminous, offering moderate energy content at lower sulfur levels, making it attractive for certain power generation applications. Colombia and Canada are the leading suppliers under this heading, with Hong Kong and China also present in import flows. Correct rank determination — typically based on calorific value and volatile matter — is essential to distinguish sub-bituminous coal from bituminous or lignite entries.
