Classification

Classification of Chemicals under HSNO

The control of chemicals under HSNO is dependent on the classifications – as defined in the HSNO regulations. There are over 100 different classifications, all with different controls associated.

The classification of some products can be simple, but for most, it requires a basic chemical knowledge, and in some cases extensive expertise in chemical properties. The classifications can be estimated at this time, although the exact classification will not be known until ERMA finalise the transfer for the specific product(s).

Estimating the classification of different products is particularly important for larger companies/sites who may need greater lead time to make changes necessary to comply with HSNO when their substances are transferred.

Note: Classifications for defined dangerous goods and scheduled toxic substances have been published by ERMA (www.ermanz.govt.nz)
