Subheading 9001 30 of the Combined Nomenclature covers contact lenses intended for use on the eye. These are optical elements of transparent polymers (e.g., silicone hydrogel, PMMA, conventional hydrogel) formed into a corrective or protective shape and placed directly on the cornea. The subheading covers: daily disposable lenses, bi-weekly and monthly replacement lenses, rigid gas-permeable (RGP) lenses, toric lenses for astigmatism, multifocal contact lenses, and cosmetic (coloured) lenses intended to be worn on the eye. The classification criterion is placement directly on the eye surface with an optical function (vision correction, protection or cosmetic alteration). Contact lenses are classified in Chapter 90, not Chapter 39 (plastics), because the essential character of the product is optical and medical. The Chapter 84 vs. Chapter 90 boundary: Chapter 90 covers elements whose principal function is optical or metrological, regardless of the material. Classification follows GRI Rule 1 and HS Explanatory Notes to heading 9001.

Contact lenses are Class IIa medical devices under MDR (EU) 2017/745, which replaced Directive MDD 93/42/EEC. CE marking is mandatory and requires involvement of a Notified Body to audit the technical documentation and the manufacturer's quality management system (ISO 13485). The manufacturer must maintain complete technical documentation, conduct a clinical evaluation in accordance with MDR Annex XIV, implement a post-market surveillance system (PMSS) and register the device in the European EUDAMED database. A distributor or importer of devices from non-EU manufacturers must appoint an EU Authorised Representative registered in EUDAMED with withdrawal procedures in place. The key harmonised standard is ISO 18369 (contact lenses series). Lenses must be sterile (EO or radiation sterilisation) or user-sterilisable. Labelling must comply with MDR Annex I: language of the country of import, manufacturer symbol, expiry date, UDI (Unique Device Identifier) code. Customs authorities may check CE marking and EUDAMED registration at the border.

Contact lenses under subheading 9001 30 may benefit from a 0% MFN duty rate under the WTO ITA Agreement or other trade arrangements. The current MFN rate must be verified in the European Commission's TARIC database. Preferential duty rates under EU FTA agreements (CETA, EU-Japan EPA, EU-UK TCA) are available upon compliance with rules of origin, documented by an EUR.1 certificate, invoice declaration or REX statement. Chapter 90 products are entirely excluded from CBAM (Regulation (EU) 2023/956). Imports of contact lenses as medical devices are subject to customs and health border controls: authorities may verify CE marking, Notified Body certificate validity, EUDAMED registration and MDR compliance documentation. Missing CE certification or invalid EUDAMED registration results in the shipment being detained. Cosmetic contact lenses (Class I MDR but with eye contact) also require a declaration of conformity and manufacturer registration. Required import documents: commercial invoice, transport document, CE declaration of conformity, Notified Body certificate, EUDAMED device registration number.

Contact lenses classified under CN 9001 30 are subject to strict sterility and packaging requirements when imported into the EU. As Class IIa medical devices under MDR 2017/745, they must be individually sealed in hermetic blister packs with saline solution. Each package must bear a UDI (Unique Device Identification) number, expiry date, and CE marking with the notified body number. Importers must ensure transport conditions maintain 1–30°C temperature and protect against UV radiation. Non-compliant shipments face border detention by market surveillance authorities.
