Guidelines and General Information

1. The term “noxious atmosphere” has the same scope in every tariff item in which it occurs.

2. The Canadian International Trade Tribunal (CITT), in its decision in AMD Ritmed v. the President of the Canada Border Services Agency (AP-2014-013-/015) established that a hospital environment is a “noxious atmosphere” as many serious and even life-threatening types of infection are present in a hospital setting.

3. The decision also confirmed that isolation gowns are a protective suit as it protects parts of the body from exposure to infections.

What is a Noxious Atmosphere?

4. Noxious atmospheres are:

5. The noxious substance or contaminant may be in the air, in a gas, in a liquid/fluid, on/in a surface/object, or in an infected host organism (e.g., human, plant or animal).

Goods to be employed in a noxious atmosphere

6. Goods typically worn by health care workers (HCW) as personal protective equipment (PPE) will qualify for classification under one of the applicable tariff provisions if they meet the terms of the heading, subheading and tariff item and are not more specifically classified elsewhere.

7. For example, subheading 4015.11 specifically provides for surgical gloves of vulcanized rubber other than hard rubber; therefore surgical gloves of vulcanized rubber other than hard rubber cannot be classified under subheading 4015.19, which includes tariff item 4015.19.10 (“Protective gloves to be employed with protective suits in a noxious atmosphere”).

8. The use of PPE goods is recognized internationally as critical control measures to help mitigate against the transmission of infection, disease and other life-threatening hazards.

PPE standards and/or technical specifications

9. The World Health Organization (WHO), the Canadian Centre of Occupational Health and Safety (CCOHS) and the United States Center for Disease Control (CDC) and other internationally recognized health and safety organizations have guidelines and recommendations with respect to the use of PPE in managing the risks posed by hazards found in noxious atmospheres, including infection prevention and control.

10. For tariff classification purposes, and consistent with CCOHS guidelines, in order for a particular PPE good to qualify as “to be employed in a noxious atmosphere”, it must be certified by an internationally recognized standards body as suitable for such use.

11. A list of goods that may qualify under “to be employed in a noxious atmosphere” tariff items, and their respective safety standard designations, are provided in Appendix A Table of Personal Protective Equipment (PPE) Goods and Standards and/or Technical Specification Requirements to qualify “to be employed in a noxious atmosphere”.

12. A list of recognized certifying bodies is provided in Appendix B Table of Recognized Certifying Bodies for Personal Protective Equipment (PPE).

Additional Information

13. For certainty regarding the tariff classification of a product, importers may request an advance ruling on tariff classification. Details on how to make a request for a tariff classification advance ruling are found in CBSA Memorandum D11-11-3, Advance Rulings for Tariff Classification, which is found on the CBSA website.
