The application

This application is referred to as the Chemical Review 2015. We are processing this application as a modified reassessment, so only specific aspects of the approvals will be considered during the reassessment, and the approvals cannot be revoked in this process.

We are proposing to update the hazard classifications of the substances to take into account new information such as study data, and reviews or assessments by overseas chemical regulators. Any changes to hazard classifications may also have an effect on the controls (rules) that apply to the substances.

The chemicals listed below may be of particular interest to submitters, either because the hazard classification changes are extensive, or because they are widely used components of many products in New Zealand. 

For example, iodocarb is a fungicide and antimicrobial used in paints, agrichemicals, and timber treatment products; propazine is an agricultural herbicide; and sulfur is used as a fungicide, a fertiliser component, in animal care and nutritional products, and has many other industrial uses.

  • Benzaldehyde
  • Butylated hydroxytoluene (BHT)
  • N-methylpyrrolidinone (NMP)
  • Furfuryl alcohol
  • Iodocarb
  • Propazine
  • Sulfur

Suppliers, manufacturers and users of chemical products should check the application documents to see whether their products are affected by the proposed changes.

Grounds to reassess the substances included in the Chemical Review 2015 were granted in June 2016 based on new information provided by a number of different external parties and supported by study data and/or assessments by overseas chemical regulators.
