Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sack kraft specs met (60-115 g/m², tear/tensile minima)
Sack kraft requires chemical sulfate fibers with specific stretch/tear values, not applicable to ultra-low weights.
If >40% sulfite process fibers for wrapping paper
Sulfite wrapping paper has ash ≤8% and different burst index, excluding mainly recovered pulp testliner.
If uncoated but weighing <15 g/m² without liner properties
General lightweight paper lacks testliner burst specs, falling under earlier headings for printing grades.

Import Tips & Compliance
• Request supplier's interpolated Mullen strength data if weight deviates from standard tables
• Declare exact basis weight on entry; customs often weighs samples for subheading 4805.24.50 accuracy
• Pair with EPA recycling certifications for preferential duty treatment under certain trade programs

Ultra-Lightweight Recycled Testliner Paper
This is an uncoated testliner paper made mainly from recovered waste paper, weighing only 12 g/m², used as a lightweight liner for corrugated packaging. It meets the HTS 4805.24.50.00 criteria with a Mullen burst index not less than 2 kPa·m²/g and is supplied in rolls for corrugating machines. Its low weight makes it ideal for specialty thin packaging applications.
Tissue-Weight Recycled Linerboard
An extremely thin testliner paperboard at 10 g/m², produced from recycled paperboard scrap with a dyed surface layer, suitable for delicate inner packaging liners. Classified under HTS 4805.24.50.00 due to its low weight, uncoated state, and testliner burst properties. Primarily used in lightweight corrugated flute protection.
Low-Grammage Recycled Corrugating Liner
Uncoated paper in rolls weighing 11 g/m², composed mainly of recycled pulp with a surface layer of unbleached pulp, exhibiting testliner strength for corrugating medium liner. Precisely matches HTS 4805.24.50.00 for weights not over 15 g/m². Ideal for minimizing material in sustainable packaging.
Featherweight Testliner from Scrap Pulp
Specialty testliner paperboard at 9 g/m² from 100% scrap paper recovery, with Mullen burst index exceeding 2 kPa·m²/g, uncoated in jumbo rolls. Classified in HTS 4805.24.50.00 for its ultra-low weight and recycled composition per subheading notes. Used in micro-corrugated board production.
