Osier, esparto, rush, reed, and similar plant materials used in basket-making, mat-weaving, and traditional crafts occupy this residual heading when they are not bamboo or rattan. USDA APHIS phytosanitary requirements apply, as unprocessed plant material carries pest and disease risk, and phytosanitary certificates from the country of origin are standard documentation. The 'primarily for plaiting' criterion is the key classification test — material that has been further processed into finished articles generally moves to textile or basketwork headings. Importers dealing in mixed consignments of plaiting materials should ensure each species is correctly identified to avoid misclassification.
