Chapter 29 Note 1(a) covers separate chemically defined organic compounds, whether or not containing impurities, while Chapter 27 Note 1(a) excludes such compounds except pure methane and propane. As the products were not shown to fall outside that class, impurities did not prevent classification under Chapter 29, and the chapter notes were treated as controlling over the tariff heading description.
