Rule 3a-MOST SPECIFIC .
Rule 3b-ESSENTIAL CHARACTER .
Rule 3c- LAST IN NUMERICAL ORDER .
Explanation: Rule 3 (a) states that where 2 or more Headings seem to apply, the one which provides the most specific description of the product in question should be used. This means that a Heading which names the actual product should be used in preference to one which only names a category to which the product could belong. Similarly, a Heading that describes the whole product should be used in preference to one which describes part of it. However, where two Headings both only describe part of the product, this rule cannot be used to tell which one to use even if one seems more specific or detailed than the other..
Mint tea is not stated specifically, as a product, in the Tariff. Although the product descriptions available are mint and tea, the importer must classify mint tea under the appropriate tea Heading because it provides the most specific product description and mint is only the flavour of the tea
Explanation: Rule 3 (b) applies to mixtures, composite goods and sets that cannot be classified by use of the previous Rules. These should be classified as if they consisted of the material or component which gives them their essential character.
Explanation: Rule 3 (c) is for use in cases in which a good seems to fit in more than one Heading and the essential character cannot be determined. In this case, the product should be classified under the Heading which occurs last in numerical order.
Exemple: A gift set which includes socks (Heading number 6115) and ties (Heading number 6117) cannot be classified by the previous rule since neither item gives the gift set its essential character. The gift set must be classified under the Heading number for ties which is the Heading that occurs last in numerical order.
