Brown Marmorated Stink Bug Regulations

Published: 05 May 2021

Seasonal measures introduced by Australia, New Zealand and Chile to combat marmorated stink bug risk.

Joint-measures by Australia and New Zealand to keep out Brown Marmorated Stink Bugs ( BMSBs). 

There has been an increasing widespread of the BMSBs throughout Europe and North America. In response to that and to keep these bugs out of their countries, New Zealand and Australia have come together to tighten up their measures to ensure that seasonal measures in place are consistent whenever possible to make compliance easier for vessels carrying cargoes to these countries. 

They have introduced a joint ‘Offshore BMSB Treatment Providers Scheme’. A list of approved treatment providers for the 2020/21 BMSB risk season is jointly maintained by New Zealand’s Ministry for Primary Industries (MPI) and the Department of Agriculture in Australia and published on both websites.

Note also that the list of targeted list of countries having BMSBs has increased for both countries to 37 countries now with Kazakhstan, Moldova, Portugal and Ukraine being added for the current season of 2020-21.  The following countries have been identified as emerging risk countries and may be selected for a random onshore inspection: 

Belarus, Denmark, Ireland, Sweden, United Kingdom and Chile 

The governments are also monitoring other countries through a lower rate of random inspections and this includes all remaining European countries, China, Korea, Taiwan, Argentina, South Africa and Uruguay. 

Australian Brown marmorated Stink Bugs (BMSBs) requirements

BMSBs pose a high biosecurity risk to Australia. This is an invasive pest, native to Asia, and is highly capable of hitchhiking, highly mobile in nature and lack of effective lures. They can severely impact the Australian agricultural industries as well as a nuisance pest to homes, vehicles and factories, seeking shelter in these areas over the winter. They are more frequently found on goods arriving in Australia between September and April, coinciding with the late autumn and winter seasons in the northern hemisphere. 

Due to the high risks posed by BMSBs, the Australian Department of Agriculture and Water Resources (DAWR) has introduced seasonal measures to manage these risks. For the 2020-21 BMSB risk season, heightened biosecurity measures will apply to:

1) certain goods manufactured in, or shipped from target risk countries, and/or
2) vessels that berth at, load or tranship from target risk countries

from 1 September 2020 and that arrive in Australian territory by 31 May 2021 (inclusive).These seasonal measures will apply between 1 September 2020 and 31 May 2021; both dates inclusive.

Goods shipped between 1 September 2020 and 30 April 2021 need to be treated, and will be referred for intervention if they arrive by 31 May 2021 (inclusive).

For goods that are shipped prior to 30 April and arrive after 31 May, they may be subject to intervention as required.


Between 1 September 2020 and 31 May 2021, the department has seasonal measures for vessels to manage the risk of BMSBs.

All roll-on roll-off (ro-ro) vessels that berth at, load or transship in target risk countries from 1 September 2020 and arrive in Australian territory by 31 May 2021 (inclusive). will be subject to the following:

  • seasonal pest questionaire as part of their pre-arrival reporting
  • directed to perform a self-inspection and report findings through the Seasonal Pest Questionaire
  • undergo a mandatory seasonal pest inspection on arrival in Australia

RoRo vessels will only be exempt from mandatory seasonal pest inspections when they can demonstrate that all cargo has:

•Been treated by a BMSB approved method, or;
•Is covered by an approved Safeguarding Arrangement, or;
•Complies with New, Unused and Not Field Tested (NUFT) criteria,
•No insects have been detected on board.

Other vessels must report the detection of any insects as part of their ordinary pre-arrival reporting. When BMSB, or other actionable exotic species are reported, the vessels will be directed to perform a self-inspection.

Australia offers a Vessel Seasonal Pest Scheme which is an alternative vessel clearance pathway for RoRo vessels. For more details to apply to the scheme, refer to Australia Vessel Seasonal Pest Scheme information section.

Target risk countries

Any target high risk or target risk goods manufactured in, or shipped from these countries are subject to the BMSB seasonal measures.  Any vessel that that berths at, load or tranships from these countries are also subject to BMSB seasonal measures:

  • Andorra
  • Armenia
  • Austria
  • Azerbaijan
  • Belgium
  • Bosnia and Herzegovina
  • Bulgaria
  • Canada
  • Croatia
  • Czech Republic

  • Turkey
  • Ukraine
  • United States of America
  • Japan (heightened vessel surveillance will be the only measure applied).

Target high risk or target risk goods 

Some goods manufactured in, or shipped from the target risk countries as sea cargo have been identified as target high risk or target risk goods. To view the list as well as how these goods should be subject to BMSB treatments, please click on this DAWR link here.  In general, the only target high risk goods will require mandatory treatment. Mandatory offshore treatment of target high risk goods shipped as break bulk cargo, including goods shipped in open top containers or on flat rack containers, will be required. Untreated break bulk or treated by an unapproved treatment provider will be denied discharge and be directed for export on arrival. 

Containerised cargo - mandatory offshore and onshore treatment of target high risk goods shipped in sealed six hard sided containers will be required. LCL and FAK containers with target high risk goods will be managed at the container level for BMSB risk prior to deconsolidation. Containerised cargo (other than LCL and FAK containers) will require mandatory offshore or onshore treatment of target high risk goods shipped in sealed six hard sided containers and deconsolidation or segregation of goods will not be permitted. 

All target high risk and target risk goods will be subject to increased onshore intervention through random inspection. 

Throughout the season, the measures based on detections of BMSB and the risk pathways would be continuously reviewed.

New Zealand BMSB requirements

The BMSB risk season starts on 1st September and the BMSB measures apply to new and used  target vehicles, machinery, and parts exported from BSMS-risk countries during the BMSB-risk season; on or after 1st September and which will arrive in New Zealand (NZ) before or on 30 April. The measures also apply to sea containers from Italy during the BMSB-risk season.

There is one exception to this rule: BMSB management is not required if target vehicles, machinery, and parts are loaded into a fully enclosed container which is sealed before 1 September and then exported before 1 October of the same year.

To assess whether your import of vehicles, machinery and parts arriving as seafreight to NZ have to meet the BMSB requirements, check the import health standard, 31 August 2020 where the various commodities are listed as some types may be excluded from the measures. 

For vehicles, machinery and parts to comply with BMST measures, they must be treated by an MPI-approved offshore treatment provider before arrival in New Zealand. Note that there are no MPI-approved treatment providers in Australia. Goods bound for New Zealand cannot be treated for BMSB in Australia. For full details, see Import Health Standard, 31 August 2020

Note also that there are transshipping requirements to comply with if these goods manufactured in a non-BMSB-risk country are transhipped through a BMSB-risk country on their way to NZ. See section 9.2 of the Import Health Standard.

Chilean BMSB requirements

Servicio Agricola y Ganadero (SAG) Resolution No. 971/2018 (Spanish only), requiring fumigation of goods from United States to Chile. This resolution was further amended in 2019 (No. 5607/2019) to include measures applicable for used vehicles and vehicle parts.  

Members operating ships to Australia, New Zealand and Chile are urged to familiarise themselves of the above BMSB requirements and compliance and for translation to get local agents to arrange accordingly.
