Heading 3827

Mixtures containing halogenated derivatives of methane, ethane or propane, not elsewhere specified or included

20 declarable lines

Heading 3827 covers mixtures that contain halogenated derivatives of methane, ethane or propane and are not covered by another heading. It is split first by the substance family, such as CFCs, halons, HCFCs, methyl bromide, HFCs and PFCs, and then by specific blend thresholds or by an other line.

Products in this heading

Refrigerant blends containing HCFCs but no CFCs
Refrigerant blends based on HFC-134a or HFC-125
Halon fire suppression agent mixtures
Foam blowing agent mixtures containing HFCs
Aerosol propellant blends containing HFCs
Solvent blends containing carbon tetrachloride
Methyl bromide fumigant mixtures

How to choose the right subheading

Identify the halogenated substances present and their percentages by mass, because many subheadings depend on thresholds such as 15% HFC-143a or 55% HFC-125.
Check whether the mixture contains CFCs or HCFCs, since their presence moves it to earlier subheadings and away from the HFC-only lines.
Determine whether the product is a bulk mixture or a retail article such as an insecticide or fire extinguisher, because articles can fall outside heading 3827.
Use 3827.90 when the mixture does not fit a specific substance family, with 3827.90.10.00 for chlorinated but not otherwise halogenated products.

Often confused with

Frequently asked questions

What is the HTS code for an HFC refrigerant blend?

A blend containing other HFCs but no CFCs or HCFCs is classified in 3827.61.00.00 through 3827.69.00.00, depending on the HFC and its percentage. For example, 3827.69.00.00 covers other HFC blends and has a general (MFN) rate of 3.7%.

What is the duty on a mixture containing carbon tetrachloride?

A mixture containing carbon tetrachloride is classified in 3827.13.00.00 and the general (MFN) rate is 6.5%.

How do I classify a cleaning solvent blend that contains chlorinated hydrocarbons but no other halogenated substances?

If the blend is chlorinated but not otherwise halogenated, use 3827.90.10.00, which has a general (MFN) rate of 6.5%. If it contains other halogenated families, classify by the specific subheading that matches those substances.
