BTI (Binding Tariff Information) is an official EU customs decision confirming the classification of goods. Valid for 3 years, binding across all EU member states.

Classification scope and characteristics

CN code 320290 covers other synthetic organic tanning substances and tanning preparations containing natural substances, inorganic tanning substances, and pre-tanning preparations. This includes syntans, enzymatic preparations used in tanning, and mixtures of synthetic and natural tanning agents. These substances are widely used in the leather industry as alternatives to or supplements for traditional vegetable and chrome tanning agents. Classification requires identification of the chemical composition and intended use of the product. Purely enzymatic products used in tanning may also be classified under this heading, provided they are prepared as tanning preparations.

Chemical regulations and import requirements

Synthetic tanning substances are subject to full REACH, CLP requirements, and Safety Data Sheet obligations. Particular attention should be paid to formaldehyde-based substances, which are listed as SVHCs and subject to restrictions under Annex XVII of REACH. Preparations containing hexavalent chromium are subject to restrictions under REACH and the RoHS Directive. CLP labelling must account for all hazardous components according to their classification. The Safety Data Sheet must be provided in the official language of the destination country. Transport of chemical preparations is subject to ADR regulations, and storage must comply with environmental and occupational health and safety requirements.

International trade and customs procedures

When importing synthetic tanning substances under CN code 320290, customs declarations should include full product specifications, CAS numbers of main components, and information on intended use. Verification under the Dual-Use Export Control Regulation (EU) 2021/821 is advisable, although most tanning substances are not listed as dual-use goods. Importers may benefit from tariff preferences under EU trade agreements, such as agreements with Turkey or Mercosur countries, provided rules of origin are met. Quality control of imported tanning preparations is important due to EU leather industry requirements regarding restricted substance content.

VOC standards and emission limits

When importing Synthetic tanning substances (CN 3202 90) 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.

Frequently asked questions

Are enzymatic preparations for tanning classified under CN 320290?
Yes, enzymatic preparations intended for leather tanning may be classified under CN code 320290, provided they constitute ready-made tanning preparations. Pure enzymes without a tanning purpose are classified under heading 3507. The actual application and commercial form of the preparation are decisive factors.
What REACH restrictions apply to formaldehyde-containing tanning preparations?
Formaldehyde is an SVHC classified as carcinogenic category 1B. Tanning preparations containing formaldehyde are subject to Annex XVII REACH restrictions, including emission and concentration limits in finished articles. The importer must ensure compliance with applicable limits and provide a current SDS.
Does importing tanning substances from Turkey benefit from tariff preferences?
Yes, under the EU-Turkey customs union, industrial goods including synthetic tanning substances under CN code 320290 may benefit from duty exemption or preferential rates. An A.TR movement certificate confirming the goods are in free circulation in Turkey is required.
What VOC limits apply to paints and coatings CN 3202 90?
Paints and coatings under CN code 3202 90 are subject to VOC limits per Directive 2004/42/EC. Matt decorative paints: max 30 g/l, gloss decorative paints: max 100-150 g/l, industrial coatings: limits vary by application.
