Division 8

For the purposes of heading 3917, the expression ‘tubes, pipes and hoses’means hollow products, whether semi-manufactured or finished products, of a kind generally used for conveying, conducting or distributing gases or liquids (for example, ribbed garden hose, perforated tubes). This expression also includes sausage casings and other lay-flat tubing. However, except for the last mentioned, those having an internal cross-section other than round, oval, rectangular (in which the length does not exceed one-and-a-half times the width) or in the shape of a regular polygon are not to be regarded as tubes, pipes and hoses but as profile shapes.
