1. What makes a set
Goods put up together in a set for retail sale, meeting a particular need.
They are classified by the component that gives the set its essential character.
2. The three conditions
Different articles
The components must be classifiable under different headings.
A particular need
They must serve a specific activity or purpose together.
Retail presentation
They must be put up for retail sale as a set.
All three must hold.
3. Finding the essential character
There is no formula. Three factors are weighed:
Value proportion.
Functional importance.
Necessity of use.
The component that carries the set’s purpose is the one that decides the code.
4. Sets versus composite machines
Composite machines
Several machines combined to perform one function. Classified by the principal function.
Sets
Several articles sold together, each with its own function.
Both rely on essential character, applied to different objects
5. Sets versus mere packaging
Goods packed together but unrelated in function are not a set.
They are classified separately.
This is where most disputes arise, and the notes often decide them.
6. The common errors
Treating anything boxed together as a set.
Being unable to identify the essential character, and defaulting to the highest-value item without justification.
Ignoring chapter notes that address sets specifically.
7. A working habit
Keep the retail packing as sold, a record of the value proportions, and a written statement of the particular need the set serves.
Those three are the supporting evidence for the classification.
8. Closing view
Classifying a set comes down to one judgment: which item is the lead.
Identify the lead, and the code follows.
