Dear Cecil, Our business produces cables and wire harness. Can this trade be classified as under metal element (for the copper wire in the cables) or still falls under "manufacturing" which is water element? Noticed about "clothing" falls under "earth" element. what about making of equipment pouches / storage bags which are typical made of nylon, polyester materials (synthetic materials) able to cat. under "clothing" or still under manufacturing? Can certain trades falls under "hybrid" elements? what is the classification process?
