Minimum Stockholding Requirements

Minimum Stockholding Requirements (MSR) require Responsible Persons to hold a minimum of either 4 or 6 months’ of stock in Australia for certain PBS listed medicines, referred to as ‘Designated Brands’. The MSR is a legislative requirement under Division 3CAA of National Health Act 1953 (Cth) (the Act), which includes biannual stockholding disclosure and breach notification requirements.

Designated Brands

Designated brands are medicines listed on the PBS which meet one of the following criteria under s99ADHC of the Act:

  • the drug/MoA of the brand’s pharmaceutical item has been on F2 for at least 42 months and at least 30 months must have passed since the first price disclosure price reduction for any brand of the same drug/MoA (42-month clock) (s99ADHC(1)(a)). A drug/MoA is taken to have been on F2 for at least 42 months if at the end of the previous data collection period, the drug/MoA has been on F2 for at least 42 months, and on a day at least 42 months before the end of the previous data collection period, the drug/MoA was multi-branded (s99ADHC(6)); or
  • the AEMP of the brand is $4 or less (s99ADHC(1)(b)); or
  • the AEMP of the brand has been increased on and after 1 July 2022 through a new price agreement and a determination is in force in relation to the brand (s99ADHC(1)(c)); or
  • the AEMP of the brand has received a price increase on 1 October 2022 under s104B of the Act (s99ADHC(1)(d)).

Medicines that are listed in Schedule 2 of the Poisons Standard, in a quantity that is equal to or greater than the PBS quantity, are excluded from the minimum stockholding requirements.

A list of designated brands subject to stockholding requirements from 1 July 2023 is published on the Designated Brands page.

An updated designated brands list is published biannually on 1 April and 1 October. The updated list includes:

  1. A current list of designated brands as at the date the list is published.
  2. A projected list of the designated brands which will be subject to stockholding requirements 12 months after the publication of the projected list, to provide advance notice for responsible persons.

The designated brands list includes the number of months which the Responsible Person is required to keep in stock for each brand which is 4 or 6 months ‘usual demand’ or ‘another quantity’ determined by the Minister.

If the designated brand has received a price increase on or after 1 July 2022, the Responsible Person for the brand is required to hold 6 months’ supply of the brand’s ‘usual demand’. If the designated brand has not received a price increase on or after 1 July 2022, the Responsible Person is required to hold 4 months’ supply of the brand’s ‘usual demand’. Usual demand is defined under section 85B of the National Health (Pharmaceutical Benefits) Regulations 2017. Refer to the MSR Guidelines and Fact Sheets for further information about usual demand.

Stockholding Disclosure Requirements

Responsible Persons are required to provide stockholding disclosure every 6 months, by the following deadlines for each reporting period.

  1. By 11 November for the period 1 April - 30 September
  2. By 12 May for the period 1 October - 31 March

Stockholding data is disclosed to the Price Disclosure Data Administrator (PDDA). Further details of the stockholding disclosure requirements including what data is required to be disclosed are in Section 7.1 of the Guidelines.

Notification Requirements

Responsible Persons are required under the Act to notify the Department as soon as practicable of any likely or actual breach of the minimum stockholding requirement. Further details of this obligation are in Section 7.2 of the Guidelines.

If a Responsible Person notifies of a likely breach, which later proceeds to an actual breach, the Responsible Person must also submit an actual breach notification.

Notifications of a likely or actual breach of the minimum stockholding requirements must be provided on either of the following PDF or Excel formats of the notification form and submitted by email to pbsstockholding@health.gov.au.

Must be accompanied with declaration form with each submission – see below

Instructions on how to complete the notification form are included on page one of the PDF and the ‘instructions’ sheet of the Excel form. The ‘Example Notifications’ sheet of the Excel form details how different types of notifications should be entered into the notification form.

Every time the Excel format notification form is submitted to the Department (including if you are correcting or updating information previously provided), you must include with your submission the following completed, signed and dated declaration form.

Declaration for Excel format notification of likely and/or actual breaches of the minimum stockholding requirement (PDF 230KB)

Please be aware, a notification must not be delayed in submission in order to collate or schedule submission of multiple notifications in the Excel format. Failure to provide a notification as soon as practicable is a breach of the notification requirements.

If you require the Notification Form or Declaration Form in a Word document format for accessibility reasons, please email pbsstockholding@health.gov.au

For any other enquiries regarding the Minimum Stockholding Requirements, please email the Department at pbsstockholding@health.gov.au

Ministerial determinations of 'another quantity'

The Minister can exercise their discretion to make a minimum stockholding determination of ‘another quantity’ where there are practical barriers to comply with the requirement to hold 4 or 6 months of stock.

The Guidelines describe how Responsible Persons can request a Ministerial determination for another stockholding quantity for a particular brand, including the matters the Minister may consider relevant. For further detail, including the timelines for applications to be made, refer to Section 6 of the Guidelines.

To submit an application for a Ministerial determination, after reviewing the Guidelines, Responsible Persons should complete the application form linked below, and submit the application form together with any supporting documents to  pbsstockholding@health.gov.au

MSR Guidelines and Fact Sheets

The PBS Minimum Stockholding Guidelines are available at the links below and were published on 21 October 2022.

The Guidelines summarise compliance requirements and provide additional supporting detail outlining minimum stockholding requirements, reporting requirements, compliance obligations, and the process for Responsible Persons to request a Ministerial Determination of ‘another quantity’. Note: The Guidelines will be updated once the Notification Portal ‘goes live’ in 2025.

Refer to the following Fact sheets that summarise key MSR concepts for Responsible Persons:

12 Month Review

The Department has completed a 12-month review of the implementation and early outcomes of the Minimum Stockholding Requirements. The review was conducted through engagement with the medicines industry.

Overall, the review signalled that the policy has had positive impacts. The medicines industry has made changes to increase their stock levels and early data indicates a reduction in medicine shortages of designated brands. However, a 24-month review is required to evaluate the effectiveness of the MSR, its impact on medicine shortages, as well as the regulatory impact on the medicines industry. Further improvements can be made to systems and processes to reduce administrative burden and additional guidance is required in certain areas in response to feedback from industry.

Key findings and recommendations of the 12-month review are contained in the Executive Summary which is available at the links below.
