CN code 620323 covers men's and boys' ensembles of synthetic fibers, other than knitted or crocheted. An ensemble as defined in Note 3(b) to Chapter 62 is a set of at least two clothing articles made from the same or complementary fabric, forming together an outfit intended for wearing on a particular occasion. Synthetic fibers include polyester, polyamide, and acrylic. Polyester ensembles are popular in sportswear, workwear, and casual clothing due to material durability and crease resistance. Classification requires that the synthetic fiber constitutes the predominant component by weight of the fabric. Ensemble components must be packaged and sold together as a single commercial unit; otherwise they are classified separately.

Synthetic fiber ensembles imported into the EU are subject to fiber composition labeling requirements under Regulation (EU) No 1007/2011. Each component of the set should have its own label, as the composition of individual parts may differ. REACH imposes restrictions on disperse dyes used for polyester, PFAS substances in water-repellent finishes, and formaldehyde in fixation processes. Ensembles for boys are subject to stricter mechanical safety requirements - standard EN 14682 regulates the permissible length and placement of drawstrings and cords. The GPSR requires importers to conduct risk assessments considering the user age group and ensure product traceability throughout the supply chain.

Men's synthetic fiber ensembles are imported mainly from China, Bangladesh, Vietnam, and Turkey. China is the dominant supplier of synthetic clothing to the EU market. At customs clearance, traders must document that the goods constitute an ensemble under Note 3(b) to Chapter 62 - components must be packaged together and form a logical outfit. Customs authorities may challenge ensemble status if components do not meet tariff criteria. Origin rules require double transformation. Imports from Vietnam may benefit from EVFTA preferences, and from Bangladesh from EBA preferences. Verification of current duty rates and defense measures in the TARIC database is recommended before each import transaction.

Suits under CN 6203 23 in Chapter 62 cover woven (not knitted) garments, distinguishing them from analogous headings in Chapter 61. Classification in Chapter 62 requires the material to be woven - interlacing of warp and weft threads. Duty rates for woven and knitted suits may differ. Correctly specifying the CN code in the customs declaration is essential, as errors between Chapter 61 and 62 result in duty reassessment with interest.
