Tariff classification underlies almost every decision in an import. The code assigned to goods determines customs duties, VAT or consumption tax, whether a licence or certificate is needed, whether measures such as CBAM apply, and official statistics. A wrong code is not a clerical slip: it carries the risk of penalties, detention of the cargo and retroactive payment.
How to read a code
The Harmonized System (HS) is the international goods nomenclature managed by the World Customs Organization. The first six digits are the same in every country that applies it. Beyond that, each country or customs union adds its own levels: in the European Union the Combined Nomenclature has eight digits and the TARIC tariff reaches ten. The first two digits identify the chapter, the first four the heading and six the subheading.
So the same goods carry the same code up to the sixth digit whether they leave China, enter Luanda or arrive in Lisbon, but duties and requirements can differ at each destination.
The rules that decide classification
Goods are not classified by trade name or by resemblance to another product. The General Rules of Interpretation apply in order:
- Section and chapter titles are for reference only. What counts is the wording of the headings and the section and chapter notes.
- Incomplete or unassembled goods are classified as the complete article, provided they have its essential character.
- Mixtures and composite goods that could fall under more than one heading: the most specific heading prevails; failing that, the material or component that gives the essential character; and as a last resort, the heading that comes last in numerical order.
- Goods that fit no heading are classified with the goods to which they are most akin.
- Specific packaging and cases follow the goods they contain.
- Within a heading, the subheading is chosen by applying the same rules at the relevant level.
Mistakes that keep recurring
- Classifying by commercial use. A tool «kit», a cosmetics «set» or a «machine» each have their own treatment and depend on composition and function.
- Ignoring the notes. Many exclusions and definitions sit in chapter notes, not in heading titles.
- Using the supplier's code. It may be right at origin and wrong at destination, because national levels differ.
- Treating parts and complete machines alike. A machine part and the complete machine have different codes.
How to reduce the risk
Before shipping, collect the technical data sheet, composition, function and photographs. With these, an experienced customs broker or forwarder can propose a code and justify it. For repeat or high-value operations, the European Union allows a binding tariff information (BTI) request, which binds the authorities of all Member States for three years. In Angola, confirm the code with your customs broker before applying for the import licence, because requirements follow the code.
What changes in 2028
The HS is revised every five years. The edition in force is 2022 and, according to WCO and USITC documentation, the next is scheduled for 1 January 2028, with hundreds of groups of amendments. Those handling sensitive classifications should follow the correlation table between the two editions as soon as it is published.
