Record sleeves — the paper or paperboard jackets used to protect vinyl records — are explicitly enumerated to remove any ambiguity about their classification, since they could otherwise be argued to fall under printed matter or other paper articles. The explicit mention anchors them here regardless of any incidental printing or graphic design on the sleeve.

Composite containers are assessed under a GRI 3 essential-character analysis. When the paperboard body constitutes the primary structural and functional element, classification typically remains with the paper container heading. Metal or plastic end caps that are merely functional closures generally do not shift the classification, but a customs broker should review the specific construction before entry.
