What to Expect After Submitting an NPN Application

In order to sell a Natural Health Product  (NHP) in Canada, you require an NPN. NPN stands for Natural Product Number, this is a product license that is issued by the Natural and Non-prescription Health Products Directorate (NNHPD) of Health Canada. The NNHPD oversees all NHP applications submitted by the Natural Health Products Regulation (NHPR).

For starters obtaining an NPN can take anywhere between 60 days to 210 days depending on the class of the application (Class I, II, and III). Safety, efficacy, and quality of products and ingredients are important. The NNHPD has developed what is known as a Compendium of Monographs. These Monographs are used to support NPN applications and can speed up the evaluation of safety and efficacy for certain medicinal ingredients. Determining the correct Class of NPN application is important, if the class is not identified correctly the application may be refused. Learn more about the different NHP application classes here: The Difference between a Class I, II, and III NHP Application

What comes next after you have successfully submitted your NPN application?
  1. Administrative Verification

The NNHPD will verify the NPN application and screen for any deficiencies. You will receive a Notice of Refusal if the application contains any issues or deficiencies. Class II and III applications that meet all screening requirements will receive an Application Acknowledgement Letter before proceeding to the regulatory screening stage. The acknowledgment letter will contain more information regarding the application, you will receive the official date of receipt of the application and a five-digit submission number. This submission number will be important for future communications with Health Canada regarding your application. 

Information Request Notice

The NNHPD will provide you the opportunity to address any non-administrative deficient or missing deficiencies through an Information Request Notice (IRN), as per Section 15 of the NHPR. The IRN will contain a specified response time between 2 to 15 calendar days depending on the information being requested. 

  • Class I applications: may be issued an IRN for brand names or other non-significant deficiencies 
  • Class II and III applications may be issued an IRN for non-significant deficiencies during the regulatory screening stage
  • Class III applications may be issued IRNs during the assessment stage  
  1. Regulatory Screening 

After the applications have undergone administrative verification, all NPN applications will be screened against all regulatory requirements mentioned in the NHPR. The application will be screened against all parameters of the NNHPD monographs, and a Notice of Refusal will be issued, if there are any significant deficiencies during the screening process. 

Significant deficiencies include: 

  • Incomplete or inaccurate information on the product license application form 
  • Missing mandatory application requirements, such as FPS, product label text, supporting evidence for safety and/or efficacy, letters of access, animal tissue form, and/or attestation forms 
  • The product does not meet the definition of an NHP
  • Did not meet the parameters of an NNHPD monograph to which the product attested 

A Notice of Refusal will also be issued if you do not submit the requested information in response to an IRN within the timelines specified in the notice. 

  1. Safety and Efficacy Assessment (For Class III NPN Applications Only) 

Upon successful completion of the regulatory screening process, all Class III applications will be further assessed for the safety and efficacy requirements. A Notice of Refusal will be given during assessment if the IRN is not submitted within the timelines specified by Health Canada. 

  1. Withdrawal of an Application 

At any time during the application process, you may withdraw the application by submitting a request to the NNHPD or if the withdrawal is in response to an IRN response, to the submission coordinator via epost Connect™. Any withdrawals will be acknowledged in writing, if you wish to re-submit the application in the near future the application will be treated as a new application. 

  1. Decision Issuance 

Once NNHPD has completed the processing of a Product License Application (PLA) they will come to a regulatory decision of either giving you a product license or refusal. 

A Product License will be issued for applications that meet all the regulatory requirements outline in the NHPR. The Product License will include an eight-digit NPN, or Drug Identification Number-Homeopathic Medicine (DIN-HM) assigned to the product and this number is required to be present on the front panel of the NHP product label. Lean more about what is required on an NHP label here: The Components of an NHP Label All licensed NHPs can be found online on the Licensed Natural Health Products Database (LNHPD) website the status of the licensed product on the LNHPD will appear as “Active”. 

A Notice of Refusal will be issued for applications that do not meet the requirements of the NHPR. A reconsideration is available if you choose to make a valid argument against the refusal. If you wish to submit additional information for the product which you received a Notice of Refusal, a brand-new application must be submitted.
