ANNEX Description of the goods Classification (CN code) Reasons (1) (2) (3) Deoxyribonuclease enzyme, with an activity range of 10 000 to 25 000 units/mg, in an aqueous storage buffer of pH 6,5. The product is put up for retail sale for laboratory use in the reverse transcriptase polymerase chain reaction (RT-PCR). 3507 90 90 Classification is determined by General Rules 1 and 6 for the interpretation of the Combined Nomenclature and by the wording of CN codes 3507 , 3507 90 and 3507 90 90 . The form of preparation of the product enables enzyme activity to be maintained during storage. The product does not contain any other substances apart from the enzyme itself allowing a detection reaction to be carried out. Therefore classification under heading 3822 as a diagnostic or laboratory reagent is excluded. Given the product's composition, it is to be considered a prepared enzyme within the meaning of heading 3507 . The product is therefore to be classified under CN code 3507 90 90 as other prepared enzyme not elsewhere specified or included.
