Made from annual-plant straw fiber rather than wood pulp, straw fluting paper is a niche corrugating medium with distinct raw-material origins and performance characteristics compared to semichemical or recycled alternatives. The US schedule subdivides this heading by basis weight: 4805121000 covers material under 150 g/m², while 4805122000 covers material at or above that threshold. Mexico is the leading US supplier, followed by France and Italy — a supply profile that reflects both geographic proximity and European agricultural-residue paper traditions. Importers should verify that the fiber furnish is genuinely straw-based, as misclassification against semichemical or other fluting subheadings is a common audit issue.

4805121000 covers straw fluting paper weighing less than 150 g/m², which is typically used for lighter-duty corrugated applications, while 4805122000 covers heavier grades at 150 g/m² or more, suited for more demanding structural uses. The weight cutoff is measured as grams per square meter of the finished sheet, and mill test certificates or roll-weight calculations are the standard documentation for establishing the correct line at entry.
Customs may request a mill certificate or fiber analysis confirming that the furnish is derived from cereal straw or other annual-plant residues rather than wood pulp. A semichemical process applied to wood fiber would classify under 4805110000, not here. Providing a detailed technical data sheet from the manufacturer that identifies the raw material source is the most reliable way to support the straw-fluting classification.
