What do Sections D and E not decide in ISIC Rev. 5?

Sections D and E in ISIC Rev. 5, published by the UN Statistics Division, do not decide tariffs, licences, environmental permits, safety compliance or any reader’s legal obligations. They are statistical descriptions used to group similar activities so that production, employment and related data can be compared. A code in Section D or E says what kind of activity is being described, not whether that activity is lawful, licensed or compliant in a particular country. Readers who need a licence or a permit must consult the regulator for that field, and readers who need a code confirmed must consult the national statistical institute or business register that holds the record.

Why can a waste operator be counted in Section E and still need a separate permit?

Take the waste operator case in full. For statistical purposes, the operator’s work of collecting, treating or disposing of waste is described in Section E. That description helps a statistician count the activity alongside similar activities elsewhere. It does not, by itself, authorise the site to operate. A separate environmental permit, issued by the environmental regulator, decides whether the site may operate at all, under what conditions, and for what kinds of waste. The two decisions come from different bodies, under different law, for different purposes. One counts; the other permits. Confusing them would be like assuming that being listed in a directory grants permission to trade.

Which decisions sit outside Sections D and E?

The following topics are not decided by Sections D and E, and are listed here as excluded topics, not as activities inside the grouping. They are described in this guide only to mark the boundary of what a statistical code can do:

• Prices, tariffs and charges for utilities
• Licences to operate a network or plant
• Environmental permits and compliance
• Health and safety obligations
• Tax treatment or registration status

If a question concerns one of those topics, the answer will not be found in the Rev. 5 class description, however carefully that description is read. The class description can say what kind of activity is being counted. It cannot say what price may be charged, whether a licence should be granted, whether a site complies, whether a workplace is safe, or how a business should be taxed or registered. Each of those questions has its own authority, its own law and its own record holder.

Why is mistaking a code for permission more than a technical error?

Confusing a statistical code with a permission can cause real harm if a business treats a classification entry as approval. A firm that assumes its Section D or E description authorises it to operate may invest, hire and open a site without the permits it actually needs, and may face enforcement when the regulator intervenes. A firm that assumes its code settles its tax treatment may file incorrectly. The classification is neutral about permission: it groups activities for measurement, while regulators decide permission under separate law. Neutrality here is a strength, not a gap. It lets the same classification be used across countries with very different licensing regimes, because the counting does not depend on the local permission system.

What about firms that both operate a service and arrange one?

A boundary that is clear in principle can still be hard in a mixed case, such as a firm that both provides a service and arranges it, or both builds and operates. Mixed cases are handled by a principal activity rule in statistical practice, and this guide does not apply that rule to any reader, because the rule needs data about the whole unit that a guide cannot see. The same caution applies to the non decisions above: a mixed firm may need several permissions, several tax considerations and a statistical code, and no single one of those settles the others. Each must be checked with its own holder.

How can you use this guide safely, given those limits?

Share this guide with the guardrail in mind: it is general information about a statistical classification. Anyone who needs a formal code, a licence or advice for a specific situation should go to the national statistical institute, the business register or the relevant regulator, as appropriate. The guide’s value is in preventing a category error, not in replacing the bodies that decide the underlying questions.

The UN Statistics Division classification detail and the ISIC Rev. 5 publication in the frontmatter support every code statement about Sections D and E in this guide.

And to state the limit plainly one last time, in this guide’s own terms: what you have read is a statistical classification only, it does not determine your code, your principal activity or your registration, and the confirmation for any of those should come from the national statistical institute or business register that holds your record.
