HS Code vs HTS Code: What's the Difference?
The HS code (Harmonized System) is the global 6-digit product classification maintained by the World Customs Organization. The HTS code (Harmonized Tariff Schedule) is the United States' national schedule, which starts from the same 6 digits and extends them to 10 digits with US-specific duty rates.

How to convert an HS code to an HTS code
Start from the 6-digit HS code — it is identical to the first six digits of the HTS code. Then extend it using the official US schedule at hts.usitc.gov, selecting the 8-digit rate line and 10-digit statistical suffix that match your product.
For example, portable laptops fall under HS code 8471.30. The corresponding US HTS line adds the duty-free rate and statistical breakdowns for the United States.
Why the difference matters
When shipping to the United States, you must declare a 10-digit HTS code — using only the 6-digit HS code will typically be rejected by US customs entries. When shipping anywhere else, check that country's national extension (for example, the EU uses 8-digit CN codes plus TARIC).
