HS Code 5403.33 – Yarn, artificial; filament, monofilament (less than 67 decitex), of cellulose acetate, single, not for retail sale, not sewing thread
HS code 5403.33 is the 6-digit subheading for yarn, artificial, filament, monofilament (less than 67 decitex), of cellulose acetate, single, not for retail sale, not sewing thread. It is used for cellulose acetate filament yarn, acetate lining yarn, apparel-grade acetate yarn, textile-grade acetate yarn and single cellulose acetate yarn.
What HS 5403.33 covers
This HS code encompasses single filament yarns made from cellulose acetate, an artificial fiber derived from wood pulp, specifically those with a linear density of less than 67 decitex and not prepared for retail sale or as sewing thread. These yarns are highly valued in international trade for their silk-like luster, soft hand, and excellent drape, making them ideal for high-quality textile applications. Major importers are typically textile manufacturers specializing in linings, apparel, and decorative fabrics, particularly in fashion-forward regions. Exporters are often large chemical and fiber producers with advanced manufacturing capabilities. Key aspects to note include the 'single' filament structure, which contributes to a smooth, uniform yarn, and its non-retail presentation, indicating its use as an industrial raw material for further processing into finished goods.

Codes often confused with 5403.33
Common mistake. This code can be confused with other artificial filament yarns like viscose rayon (540331) or even synthetic yarns (Chapter 54, Section XI) if the specific cellulose acetate material isn't accurately identified. It's also distinct from multiple or cabled acetate yarns (540342).

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).
