What the code is
The Harmonised System is an international classification of goods. The first six digits are the same everywhere. Your destination country adds more digits, and those extra digits decide the duty rate, the quotas and whether anything special applies.

The supplier will propose a code on the export declaration. It is not their responsibility if it is wrong at your end. It is yours.
How classification goes wrong
Usually not through fraud. Through convenience. A factory that mostly exports toys will classify a sports product as a toy because that is the code in their system. A code that is convenient in China can be expensive, or illegal, in your market.
The other failure is the composite product. A kit with a racket, balls and a bag is classified by its essential character, and reasonable people can disagree about what that is. That disagreement, at customs, costs you time and money.
Getting it right, once
- Classify before the goods move, not after customs asks.
- Have your customs broker confirm the code in the destination country. They carry the responsibility with you and they know the local practice.
- Where the value is large or the classification is genuinely ambiguous, get a binding tariff ruling. It costs a little and it removes the argument permanently.
- Make the code consistent across the invoice, the packing list and the declaration. An inconsistency is an inspection.
Why it belongs in the landed cost
An importer who quotes a customer from a unit price plus freight, and discovers the duty afterwards, has just given away the difference. The duty is not a surprise. It is a number you can know before you place the order, and it belongs in the same sheet as the unit price, the tooling and the inspection.

- The tariff code decides the duty, and the responsibility at destination is yours, not the factory's.
- A code that is convenient in China can be wrong in your market.
- Confirm it with your broker before the goods move. Get a binding ruling when the value justifies it.
- The duty belongs in the landed cost sheet, next to the unit price.
