A business example

A seller adds insulated steel drink bottles to a catalogue that previously contained only plastic storage boxes.

Follow the exampleFictional business scenario

  1. Product facts

    Record the bottle's material, construction and intended function.

  2. Classification review

    Compare those facts with the relevant headings and notes.

  3. Invoice setup

    Use the supported classification in the product master and reporting.

What this shows

Reusing the old product's code because both items are containers can hide a classification error. The product specification drives the analysis.

What it is often confused with

A convenient competitor code does not establish the correct classification for your own product.

What to look at in your business

Retain product specifications and the classification reasoning, not only a code.

Context and further reading

DPIIT: Guidebook on Mapping of HSN Codes. The guidebook explains HSN as a standardised numerical system for classifying products. A code still needs to be matched to the actual goods and applicable tariff.
