Step 1: Get a good description of the product

A heat and moisture exchanging filter (HMEF), consisting of a plastic housing equipped with two 22 mm connectors and one luer lock connector. The HMEF also contains a filtering material made of glass fibres. It has a compressible volume of 65 ml and a weight of 43 grammes.

The article has the following functions:

— high-efficiency filtration,

— ease of breathing because of a low air-flow resistance,

— prevention of heat and moisture loss.

The article is designed to be mounted on a patient’s airway connector (e.g. a facemask) on one end and to be connected via tubes to the anaesthetic or artificial respiration apparatus on the other end. It is designed for use in intensive care or during anaesthesia, to provide a barrier against the passage of viruses and to heat and moisturise the air inhaled by a patient.

There is a picture:

Step 2: Build your argument, grounded in law

  1. Start with an HS section (the Roman Numbers). Which one does this product fall into?

  2. Look at the GIR/GRIs and think about which ones could apply in this case? 1 & 6 is a given, any others?

  3. Get your support tools ready. Have you got the Section and chapter notes handy? Have you got access to the national explanatory notes of your country? What about the WCO classification explanatory notes? What about BTI? Case Law?

  4. Next, consider GIR 1 and find possible competing headings and try to unravel them with careful consideration of the section and heading notes. Use all the tools, including exclusions and exceptions, to support your case.

  5. Consider any other GIR rule you think is appropriate here

  6. Look at specific rules of your national tariff, like additional notes and subheading rules for numberings past 6 digits.

  7. Draft and fine-tune your justification and conclude by determining the article.

Step 3: Write your justification

There is no fixed rule, but it should clearly answer the question: Why is this code correct and give reasons backed up by the rules of classification? The geekier, the better.

Here is an example:

Classification is determined by general rules X and X for the interpretation of the Harmonised System of Classification as published by the WCO, version of year 20XX, and (insert name of national tariff).

We considered the following Notes and wordings of HS/commodity codes:

  • note XX and xx to Section XX

  • The wording of HS codes XXXX, XXXX

  • National Tariff commodity codes: XXXX XXXX

The articles are produced in/by .... (see note XX to Section XX). Considering their xxx character the articles are to be considered as xxx. In addition, note xxx to Section xxx classifies Product A like Product B in that section. Classification under heading XXXX is excluded, because (see also the Harmonized System Explanatory Note to heading XXXX (X) and the Explanatory note to the National Tariff XXXX ). Consequently, the articles are to be classified under National Code XXXX XX XXas a xxx Now it is up to you :-) Can you try to find the 6-digit code for the WCO and the eight-digit code for the EU (or your country?)
