CN code 290522 covers acyclic terpene alcohols, including geraniol (CAS 106-24-1), linalool (CAS 78-70-6), citronellol (CAS 106-22-9) and nerol (CAS 106-25-2). These are unsaturated monoterpene alcohols naturally present in the essential oils of various aromatic plants — geraniol is the dominant component in rose and palmarosa oil, linalool in lavender and coriander, citronellol in geranium and citronella grass, and nerol in neroli and orange blossom. They are indispensable components of the fragrance, flavour and cosmetics industries, with global production based on both natural extraction by steam distillation from plant feedstocks and chemical synthesis from myrcene, citronellal or other terpene intermediates. Classification under CN 290522 applies pursuant to Note 1 to Chapter 29 only to chemically pure substances or their aqueous solutions — natural essential oils containing mixtures of terpenes, esters and other compounds are classified in Chapter 33. The distinction between a chemically defined pure substance and an essential oil mixture is critical for correct tariff classification and must be supported by analytical documentation such as a GC or HPLC Certificate of Analysis. Misclassification may lead to customs post-clearance adjustments or penalty proceedings. Where doubt exists, a Binding Tariff Information ruling should be sought from the competent customs authority.

Acyclic terpene alcohols imported into the EU are fully subject to REACH (Regulation EC No 1907/2006) — registration with ECHA is mandatory for any substance imported at one tonne or more per year. Geraniol and linalool are widely used in cosmetic formulations and therefore fall under additional obligations of the Cosmetics Regulation (EC No 1223/2009), which requires mandatory declaration of fragrance allergens in the ingredient list of finished cosmetic products. CLP labelling (Regulation EC No 1272/2008) must reflect the sensitisation and irritation classification — geraniol, linalool, citronellol and nerol appear on the EU list of fragrance allergens requiring mandatory declaration in cosmetics once defined concentration thresholds are exceeded. A Safety Data Sheet (SDS) prepared in accordance with Regulation (EU) 2020/878 and including exposure scenarios for all identified uses must accompany each delivery to professional recipients and be adapted to the specific end use communicated in the supply chain. Naturally sourced substances should be accompanied by documentation confirming isomeric composition, method of extraction and botanical origin, which is also relevant for compliance with fragrance industry quality standards such as IFRA guidelines. Additional obligations may arise under food flavouring regulations where these alcohols are used in food applications.

Importing terpene alcohols under CN 290522 into the EU requires documentation of both chemical purity (COA, GC or HPLC analysis) and, for naturally sourced material, the plant species and geographic region of origin. This information is relevant for CITES compliance verification in cases where protected plant species are involved, and for confirming sustainable sourcing practices expected by buyers in the fine fragrance sector. Geraniol and linalool obtained from palm oil or other crops from high-deforestation-risk areas may fall within the scope of the EU Deforestation Regulation (EU) 2023/1115, which imposes a due diligence obligation on operators placing such commodities on the EU market. Preferential duty rates may be available for imports from countries benefiting from the EU Generalised Scheme of Preferences (GSP, GSP+) or covered by a Free Trade Agreement — an EUR.1 movement certificate or an invoice declaration from a REX-registered exporter is required to benefit from the preference. Transport is in drums or IBC containers, with ADR requirements depending on the flammability classification of the specific substance. Current MFN duty rates and trade defence measures must always be verified in the TARIC database before concluding purchase contracts. Exporters to the EU must ensure that packaging labels comply with the language requirements of the destination member state and that the SDS is provided in the relevant official language.

Organic substances under CN code 2905 22 (Acyclic terpene alcohols) require detailed chemical documentation for customs clearance. The Safety Data Sheet must comply with REACH Annex II. Substances classified as hazardous under CLP require GHS pictogram labelling. Transport follows ADR (road) or IMDG (maritime) regulations. Some organic substances may be subject to export controls as dual-use goods. Importers should verify whether the substance requires REACH authorisation (Annex XIV) or is subject to restrictions (Annex XVII).
