Does a retail kit need one customs code?

A kit does not automatically receive one customs code. First check whether a heading or legal note already covers the goods. If not, the retail-set rules may apply. The name "kit", one price or one stock number does not answer that question. You need the components, their shared purpose and their packaging [1] [2].

Check the three retail-set conditions

The Commission's guidance describes three conditions for sets under General Rule 3(b) [2]:

1. There are at least two different articles that initially fall under different headings.
2. They are put together for a particular need or specific activity.
3. They can be sold directly to users without repacking.

Apply these within the full classification rules. Specific headings or notes can govern the goods first. A gift box or shared colour alone does not establish a shared activity [2].

Build a component checklist

For each proposed kit, collect:

• Every component, with its material, function and quantity.
• Each component's weight and value, where relevant.
• A short account of how the components work together.
• Photos of the packaging as it will reach the user.
• Whether anything is added, removed or repacked after import.
• For separate packages, evidence linking the contents and explaining the packaging.

For example, a seller calls a bundle a "repair kit". Ask which repair it performs and what each item does during that repair. A component list and pack photo let the declarant assess that claim. The marketing name alone cannot.
