HS Code 5403 — Artificial Filament Yarn

This code covers filament yarns made from chemically processed natural polymers, such as viscose rayon, acetate, or cuprammonium. These 'artificial' (not synthetic) fibres are prized for their silk-like feel and moisture absorption.

What's included

Viscose rayon filament yarn
Cellulose acetate yarn
Cupro yarn
Artificial high tenacity yarn

What's excluded

Synthetic yarns (polyester) → use 5402 (Polyester is purely synthetic; 5403 is for cellulose-based artificial fibres.)
Mono-filament over 67 decitex → use 5405 (Thicker artificial monofilaments move to heading 5405.)

Common examples

Viscose filament yarn for linings
Acetate yarn for satin fabrics
Cupro yarn for premium dresses
High tenacity viscose for industrial hoses

Frequently asked questions

Is rayon considered synthetic or artificial?

Customs classifies rayon as 'artificial' because it is derived from cellulose (wood pulp), unlike polyester which is 'synthetic' (petrochemical).

Trade & shipping notes

Typical duty range: 0% - 15%
Documentation: Identify the type of cellulose (viscose vs acetate) as duties vary by subheading.
Typical shipping mode: FCL
Top exporters: China, Germany, Japan
Top importers: Italy, India, USA

Key takeaway

Essential code for the semi-synthetic/artificial textile market, particularly for viscose and acetate.
