The only classification difference between SITC 32221 and 32222 is whether the lignite has been agglomerated — pressed or formed into briquettes, ovoids, or similar shapes. The coal rank (lignite) and the jet exclusion apply equally to both headings; it is solely the physical processing state that determines which heading applies.

There is no single international moisture or calorific standard that defines agglomerated lignite for customs purposes; classification turns on the physical form (agglomerated vs. not) rather than a moisture threshold. However, commercial contracts for lignite briquettes typically specify moisture content, ash, and calorific value, and these parameters appear in certificates of analysis that support customs documentation.
