Product classification

Product classification is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Product classification rather than just read about it. In short: Product classification or product taxonomy is a type of economic taxonomy which organizes products for a variety of purposes. However, not only products can be referred to in a standardized way but also sales practices in form of the “Incoterms” and industries can be classified into categories.

Key takeaways

Product classification belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Product classification to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Product classification from memory before moving on to harder problems.

Reference excerpt

Product classification or product taxonomy is a type of economic taxonomy which organizes products for a variety of purposes. However, not only products can be referred to in a standardized way but also sales practices in form of the “Incoterms” and industries can be classified into categories. Some standard product classifications include:

CPA — Classification of Products by Activity, a product nomenclature that was used in the European Economic Community and now in use in the EU, a European version of the CPC CPA 1996 CPA 2002 CPA 2008 CPA 2.1 CPC — Central Product Classification, a United Nations standard classification for products ETIM, the ETIM Technical Information Model Global Classification and Harmonized Schedule Numbers for customs classification HS — Harmonized Commodity Description and Coding System SITC — Standard International Trade Classification Trade in Services UNSPSC, the United Nations Standard Products and Services Code IEC Common Data Dictionary (IEC CDD), a product classification and product description based on international standards and defined by the International Electrotechnical Commission eCl@ss, a global and ISO/IEC-conform system for classification and description of products and services, maintained by the non-governmental eCl@ss e.V. association

Worked examples

Example 1 — a first encounter with Product classification

Start with the simplest possible case. Write down what Product classification claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Product classification before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Product classification ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Product classification

In research: Product classification appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Product classification in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Product classification is common in secondary-school and first-year university syllabi. It links to neighbouring topics Business stubs, Product classifications, so understanding it makes those chapters shorter.
In everyday life: Look for Product classification outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Product classification in simple terms?

Why does Product classification matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Product classification?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
