608 & 609 EPA Certifications

In order to be qualified to handle refrigerants you need to pass a test by the Environmental Protection Agency on either 608 or 609 certification.

There are different types of certifications to consider as well:

  • 608 Type I Certification – Can only work on Small Appliance (5lbs or less of refrigerant)
  • 608 Type II Certification – Can only work on Medium, High and Very-High Pressure Appliances.
  • 608 Type III Certification – Can only work on Low-Pressure Appliances.
  • 608 Core Certification – This is needed in order to achieve any type of certification rather it be section 1, 2, or 3.
  • Universal Certification – Someone who possesses Type I, Type II and Type III Certifications as well as the Core Certification.
  • 609 Certification – This is needed to work on automobile applications.

Refrigerants are a hazardous gas and storage of refrigerant should not be taken lightly. No matter if you have R-134A, R-410A, R-22, or any other kind of refrigerant you need to take the proper steps and precautions. Below are a few key points to remember when storing your Refrigerant:

  • Ensure that all your cylinders be stored up right and are without risk of tipping over.
  • Refrigerant should be stored into a well ventilated area and temperatures should NOT exceed over 125 degrees Fahrenheit. If the temperate becomes too hot pressure can build inside the container which could cause the container to rupture. This could cause the release valve to fail which could result in an explosion of the product.
  • Ensure all Refrigerant containers/cylinders have pressure release devices to avoid combustion and or explosions.
  • Ensure there are no combustible or flammable materials nearby the containers.
  • Perform regular visual inspections of your cylinders to ensure that everything is in good order.
  • Limit the number of people who have access to your Refrigerant, as the more people who have access the higher your chance of an incident. Also, please keep out of reach of children.

Refrigerant can be dangerous, or it can be very safe. It is up to you to take the per-cautions when storing your product. Well, that about covers storage requirements for Refrigerants.

Thought everyone should know about this, I didn’t write this article but it is in regards to new tariffs on R-134A refrigerant. Click here for full article. This will have a huge effect on the price of R-134A. I was buying at $68.00 earlier this year and now the best price we can get is low $100s.


Commerce Initiates Antidumping Duty and Countervailing Duty Investigations of Imports of 1,1,1,2-Tetrafluoroethane from the People’s Republic of China

  • On December 3, 2013, the Department of Commerce (Commerce) announced the initiation of antidumping duty (AD) and countervailing duty (CVD) investigations of imports of 1,1,1,2- tetrafluoroethane from the People’s Republic of China (China).
  • The AD and CVD laws provide U.S. businesses and workers with a transparent and internationally approved mechanism to seek relief from the market-distorting effects caused by injurious dumping and unfair subsidization of imports into the United States, establishing an opportunity to compete on a level playing field.
  • For the purpose of AD investigations, dumping occurs when a foreign company sells a product in the United States at less than its fair value. For the purpose of CVD investigations, countervailable subsidies are financial assistance from foreign governments that benefit the production of goods from foreign companies and are limited to specific enterprises or industries, or are contingent either upon export performance or upon the use of domestic goods over imported goods.
  • The petitioner for these investigations is Mexichem Fluor, Inc. (LA).
  • The merchandise subject to these investigations is 1,1,1,2-Tetrafluoroethane, R-134a, or its chemical equivalent, regardless of form, type, or purity level. The chemical formula for 1,1,1,2- tetrafluoroethane is CF3-CH2F, and the Chemical Abstracts Service (“CAS”) registry number is CAS 811-97-2.1,1,1,2-Tetrafluoroethane is sold under a number of trade names including Klea 134a and Zephex 134a (Mexichem Fluor); Genetron 134a (Honeywell); Suva 134a, Dymel 134a, and Dymel P134a (DuPont); Solkane 134a (Solvay); and Forane 134a (Arkema). Generically, 1,1,1,2-tetrafluoroethane has been sold as Fluorocarbon 134a, R-134a, HFC-134a, HF A-134a, Refrigerant 134a, and UN3159.Merchandise covered by the scope of these investigations is currently classified in the Harmonized Tariff Schedule of the United States (“HTSUS”) at subheading 2903.39.2020. Although the HTSUS subheading and CAS registry number are provided for convenience and customs purposes, the written description of the scope is dispositive..
  • In 2012, imports of 1,1,1,2-tetrafluoroethane from China were valued at an estimated $53.2 million.

• The U.S. International Trade Commission (ITC) is scheduled to make its preliminary injury determinations on or before December 13, 2013.

• If the ITC determines that there is a reasonable indication that imports of 1,1,1,2-tetrafluoroethane from China materially injures, or threatens material injury to, the domestic industry, the investigations will continue and Commerce will be scheduled to make its preliminary CVD determination in February 2014 and its preliminary AD determination in April 2014, unless the statutory deadlines are extended. If the ITC’s preliminary determinations are negative, the investigations will be terminated.
