Source: HS 2022 nomenclature, 6-digit level (UN Comtrade). Descriptions are in English, as in the official nomenclature. Digits after the 6th differ by country. National tariffs add 2–4 more digits and set the duty rates: confirm the full code in the destination country's tariff.
Find the heading (4 digits) that describes your product, then the subheading (6 digits). The chapter and section notes of the HS can include or exclude products, so read them in the official tariff of the destination before you decide. The first 6 digits are the same in every country that uses HS 2022; the national tariff adds more digits and sets the duty.
