Knitted or crocheted construction is the defining classification criterion here, separating jersey-knit fitted sheets, stretch pillowcases, and similar articles from the far larger woven bed-linen trade. The knitted fabric structure — which gives these products their characteristic stretch and drape — is assessed at the fabric-formation stage, not the finished-article stage, for classification purposes. Hospitality and direct-to-consumer bedding brands sourcing knit-construction sheets should confirm fabric construction documentation is available, as customs may request evidence distinguishing knitted from woven substrates.
