The composition varies considerably by producer and country. Some countries may require the addition of iodine compounds, for instance; others may not.

It does not necessarily mean that. For example glucose (C6H12O6) and formaldehyde (CH2O) have the same percentages of elements by mass, but are two very difference compounds.
It is when no chlorine compounds are used to bleach pulp
the composition varies from one compound to another
Nonstoichiometric compounds have a variable composition.
what are the composition of organic compounds? "Carbong, Hydrogen and oxygen with small amount of halogen, nitrogen, sulfur and phosphorus are the chief elements found in organic compounds." No, A composition of organic compounds are carbohydrates, lipids, proteins, nucleic acids. Source: In AP Biology.
Yes. It is calcium hypochlorite, Ca(ClO)2. Inorganic as it does not contain carbon atoms.
Hydrogen peroxide acts as a bleaching agent because it is a strong oxidizer. Because colored compounds are often caused by conjugated electrons or metal complexes, adding an oxidizer which destroys these compounds causes removal of the color.

No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
Compounds differ from mixtures; the chemical composition is different !
This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
The composition of pure substances, such as elements and compounds, are always the same. The composition of mixtures can vary.
