About this level

Practical summary

Class 0158 sits in the PSIC 2019 hierarchy under A Agriculture, Forestry and Fishing > 01 Crop and Animal Production, Hunting and Related Service Activities > 015 Support activities to agriculture and post- harvest crop activities. This class usually fans out into more specific subclasses such as Growing of Paddy Rice for Seed Purposes and Growing of Seedlings for Reforestation. It is the level people use when they already know the activity family but still need the exact five-digit match.

Administrative context

Where this code is used

This class is used when a business can already narrow the activity family and only needs to compare the final subclasses such as Growing of Paddy Rice for Seed Purposes and Growing of Seedlings for Reforestation. It is the level most often checked before a five-digit decision is finalized.

Selection note

How to choose it

Use this class to choose between its final subclasses such as Growing of Paddy Rice for Seed Purposes and Growing of Seedlings for Reforestation. If two options look close, compare the exact activity, the outputs and the way the business actually earns revenue.

Official note

How do I compare Class 0158 with the sibling classes?

Read the neighboring classes and compare the exact wording of the child subclasses. Nearby options include 0151 Operation of irrigation systems through cooperatives and non-cooperatives and 0153 Services to establish crops, promote their growth and protect them from pests and diseases.

Why does Class 0158 matter for a filing decision?

It is usually the last broad checkpoint before the five-digit subclass choice, so it is the right place to catch near-miss classifications.
