The Environment and Natural Resources Code and the Sub-Decree on ODS Management mandate that importers and exporters of ozone-depleting substances (ODS), hydrofluorocarbons (HFCs), and products containing or designed for using them must register with the Ministry of Environment (MOE) and obtain a quota specifically for the ODS and HFCs.  For each shipment, a registered importer needs to apply for an import permit from the MOE. The importer needs to show the import permit to the Customs along with other supporting documents before the shipment can be cleared. Therefore, the MOE can maintain its records of imports and later check with the General Department of Customs and Excise to verify and reconcile the import data. This exercise is carried out prior to the reporting of data to the Ozone Secretariat and the Multilateral Fund Secretariat.

• • For ODS and HFCs the MOE has set quotas for individual importers and gives an import permit to any registered importer depending on the quotas they have. The import permit will be given by the MOE once it determines that the accumulated requested quantity will not exceed the annual quotas the importer received.
    
  • For ODS and HFCs, after the importer has cleared the shipment, the importer must inform the MOE for them to inspect and apply the license sticker to the imported cylinders.
    
  
  

The quota is annually.

The license is accepted by all concerned institutions.

The implementation of an ODS and HFCs import quota system has been in operation since 2005. Any companies wishing to import ODS in the next year have to apply for a permit consistent with the national quota before 1st  November of the current year. The allocation of an annual quota is based on historical import statistics of the importers in the previous year. Moreover, the Ministry of Environment (MoE) allocates a certain amount of ODS (about 10% of the total quota) as a "buffer" for any new importers. Prior to the issuance of import permits to importers, MOE will verify that the requested quantity would not cause the annual consumption to exceed the reduction target under the Montreal Protocol.

All persons, firms and institutions are eligible to apply for licenses under restrictive licensing systems. A legal or natural person wishing to import or export or transit ozone depleting substances as stipulated in annexes of the Montreal Protocol or in the table mentioned above shall register with the Ministry of Environment to get the annual quota and license. The registration is free.

Article 4 of Sub-Decree on ODS Management: Legal or natural person wishing to import of control substances/refrigerants as stipulated in Annex 1 of this Sub-Decree on ODS Management shall register and get a quota from the Ministry of Environment.

(a) For ODS and HFCs, including Methyl bromide, licenses are contingent upon adherence to annual quota allocations. Importers must demonstrate the intended use aligns with approved QPS applications, and report usage accurately. Licenses are also subject to conditions ensuring compliance with the Montreal Protocol, international treaties and Cambodia  standards, with specific record-keeping requirements.

(b) While Methyl bromide for QPS may have specific exemptions, licensing still requires a demonstration of legitimate QPS needs. Importers must provide documentation supporting the intended quarantine or pre-shipment application. Licenses are issued with conditions mandating accurate reporting of usage, and adherence to established protocols, to minimize emissions and prevent misuse outside of defined QPS purposes.
