The first 6 digits are the same in every country that uses HS 2022. Each country adds 2–4 more digits and sets the duty in its own tariff, and the section and chapter notes can include or exclude products, so check the destination’s official tariff before you put the code on the invoice.

Common questions
What is HS code 2810?
2810 is the HS 2022 heading for Oxides of boron; boric acids. It is in chapter 28 (Inorganic chemicals; organic and inorganic compounds of precious metals; of rare earth metals, of radio-active elements and of isotopes), section VI, and is not split further: the 6-digit code is 2810.00.
Can I write 2810 on a commercial invoice?
Customs usually need at least the 6-digit subheading (for example 2810.00), and the import declaration uses the destination country’s full code of 8 to 10 digits. Use the subheading that matches your product, and confirm the national digits with the buyer, the customs broker or the official tariff.
