HS code · 6-digit subheading
HS Code 5404.19 – Monofilament n.e.c. in heading no 5404; of 67 decitex or more and of which no cross-sectional dimension exceeds 1mm
HS code 5404.19 is the 6-digit subheading for monofilament n.e.c. in heading no 5404, of 67 decitex or more and of which no cross-sectional dimension exceeds 1mm. It is used for nylon monofilament, polyester monofilament, acrylic monofilament, specialized synthetic monofilament and fishing line monofilament.
What HS 5404.19 covers
This HS code is a 'not elsewhere specified' (n.e.c.) category for synthetic monofilaments, excluding elastomeric and polypropylene types, that have a linear density of 67 decitex or more and a cross-sectional dimension not exceeding 1mm. This broad category encompasses monofilaments made from various synthetic polymers such as nylon, polyester, acrylic, or other specialized plastics. These materials are crucial in international trade for a multitude of industrial and technical applications, including fishing lines, brush bristles, filtration fabrics, and reinforcing elements. Importers are typically manufacturers requiring specific performance characteristics like strength, abrasion resistance, or chemical inertness. Exporters are often specialized chemical and fiber manufacturers. The 'n.e.c.' designation means careful identification of the specific synthetic polymer is essential for correct classification.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
