Propylene copolymers

CN code 390230 covers propylene copolymers in primary forms. Copolymers where propylene is the predominant monomer by weight are classified under this heading, with ethylene being the most common comonomer. Two main types are distinguished: random copolymers (PP-random), where ethylene units are randomly distributed in the polypropylene chain, and block copolymers (PP-block or PP-impact), containing distinct polyethylene phases in a polypropylene matrix. Random PP copolymers offer higher transparency and a lower melting point than the homopolymer, while block copolymers provide better low-temperature impact resistance. Products are supplied as granules, powder or paste. For customs classification, the key distinction is from propylene homopolymer (code 390210) and other propylene polymers (code 390290).

Propylene copolymers imported into the EU are subject to the REACH Regulation (EC No 1907/2006) regarding monomers and additive substances. Propylene and ethylene monomers are registered substances under REACH. PP copolymers intended for food contact must comply with Regulation (EU) No 10/2011, and all monomers and additives used must be listed on the authorised substances list. Propylene copolymers are widely used in food packaging, microwave containers and bottles, making food contact compliance a commercial priority. The SUP Directive (EU) 2019/904 affects the single-use packaging segment. Importers should consider EPR obligations applicable in the destination country.

When importing propylene copolymers under CN code 390230, customs documentation should include a technical specification covering copolymer composition (ethylene content), MFI, copolymer type (random or block) and commercial form. Duty rates on propylene copolymers imported into the EU may vary depending on the origin of the goods - current rates should be checked in the TARIC or ISZTAR system. PP copolymers represent a significant share of the global polypropylene market and are the subject of intensive international trade. Major exporters include Middle Eastern countries, South Korea, China and India. Preferential duty rates may be available under FTA agreements or the GSP system, provided the origin of the goods is documented.

Propylene copolymers classified under CN code 3902 30 are polymers in primary forms (granules, powder, liquid, block) imported as feedstock for plastics processing. Import requires REACH registration, Safety Data Sheets and technical specifications including molecular weight, density and melt flow index (MFI). Products intended for food contact must comply with Regulation (EU) 10/2011 and be listed on the positive monomer list.
