4819.50 - Other packing containers, including record sleeves:

This HTS category, 4819.50, encompasses a broad range of "other packing containers" made from paper, paperboard, cellulose wadding, or webs of cellulose fibers, specifically excluding those covered by sibling categories. Unlike the more specific cartons, boxes, cases, sacks, and bags detailed elsewhere under heading 4819, this classification captures packing containers that do not fit neatly into those more defined subheadings. The key distinguishing factor is that these are packing containers designed for a variety of purposes beyond general shipping or merchandising, and they are not typically the folding cartons, corrugated boxes, or large-format bags.

This category serves as a residual classification for packing containers that are distinct from the more precisely defined categories such as 4819.10 (corrugated cartons), 4819.20 (folding cartons), 4819.30 and 4819.40 (sacks and bags), and 4819.60 (office and shop articles like letter trays). Therefore, items classified here are generally designed for containment and protection during transit or storage but do not conform to the specific structural or dimensional criteria of their sibling categories.

Within this category, further subdivisions exist to refine classification based on specific types of containers. The subcategory 4819.50.20.00 addresses sanitary food and beverage containers, such as specialized wrappers or trays for consumables. Additionally, 4819.50.30.00 specifically covers record sleeves, indicating a niche application for protecting media. The residual subheading, 4819.50.40, captures all other packing containers falling under the broader 4819.50 designation that do not meet the criteria for sanitary food/beverage containers or record sleeves, thus maintaining a comprehensive coverage of paper-based packing solutions.
