CN code 320411 covers disperse dyes and preparations based thereon, used primarily for dyeing synthetic fibres such as polyester, nylon, and cellulose acetate. These dyes are characterised by low water solubility and are applied as finely dispersed suspensions. Classification under this code requires confirmation that the product is a disperse dye within the meaning of Note 3 to Chapter 32 of the Combined Nomenclature. Disperse dyes are a key raw material for the textile industry, and their quality and purity directly affect dyeing fastness and functional properties of fabrics. Import of these products into the EU requires technical documentation confirming chemical composition and intended use.

Disperse dyes imported into the EU are subject to the REACH Regulation (EC No 1907/2006). The importer must ensure each substance in the preparation is registered with ECHA. Particular attention must be paid to azo dyes that may release arylamines listed in Annex XVII of REACH (entry 43), as such dyes are prohibited in textile articles in contact with skin. CLP labelling is mandatory and must account for classification of all hazardous components. The Safety Data Sheet (SDS) must be provided in the official language of the destination country. Some disperse dyes are classified as skin sensitisers, requiring GHS07 pictogram labelling.

For customs clearance of disperse dyes under CN code 320411, the chemical specification, Colour Index number, CAS number, and active substance concentration should be presented. Verification under the Dual-Use Export Control Regulation (EU) 2021/821 is advisable, although disperse dyes are generally not on control lists. Importers may benefit from EU tariff preferences under trade agreements. Quality control of imported dyes is important given the EU textile industry requirements on restricted substances, including arylamines, heavy metals, and formaldehyde.

When importing Disperse dyes and preparations (CN 3204 11) into the EU, VOC content regulations under Directive 2004/42/EC must be considered. Decorative paints and automotive refinish products have established VOC limits. CLP classification requires appropriate GHS pictogram labelling on packaging. Pigments containing heavy metals (lead, cadmium, chromium VI) are subject to strict REACH restrictions (Annex XVII). Importers must have SDS sheets and ensure labelling complies with destination country regulations. Conformity testing may include spectrometric analysis for composition verification.
