5804 - Tulles and other net fabrics, not including woven, knitted or crocheted fabrics; lace in the piece, in strips or in motifs, other than fabrics of headings 6002 to 6006:

Heading 5804 encompasses a specific group of textile fabrics characterized by their open, net-like structure or intricate lace designs. This category includes tuiles and other net fabrics that are not produced through weaving, knitting, or crocheting. It also covers all forms of lace, whether presented in continuous pieces, cut strips, or decorative motifs, with the exception of lace fabrics classified under headings 6002 to 6006. These materials are distinguished by their open construction, often achieved through specialized techniques like bobbin lacemaking, needle lacemaking, or chemical processes that create a net.

Unlike woven fabrics of Chapters 50-57 or knitted and crocheted fabrics of Chapter 60, the items under 5804 are defined by their method of production and their distinctive open-work or net appearance. While other textile headings may include decorative elements, heading 5804 specifically targets the structure and appearance of the fabric itself as being predominantly net or lace. This heading is situated within Section XI, which broadly covers textiles and textile articles, and specifically within Chapter 58, which deals with special woven fabrics, tufted textiles, lace, tapestries, trimmings, and embroidery.

Within heading 5804, further distinctions are made based on the method of manufacture. Subheading 5804.10 specifically addresses tuiles and other net fabrics, focusing on their non-woven, non-knitted, non-crocheted net construction. The subsequent subheadings, 5804.20 for mechanically made lace and 5804.30 for hand-made lace, differentiate based on the labor-intensive methods employed in their creation. This subdivision is crucial for customs purposes as it often reflects differences in production costs, complexity, and the final aesthetic of the lace product.
