Importing air purifiers into the U.S. requires more than standard customs paperwork. The correct HTS classification, shipment documents, and agency requirements depend on how the product works, what claims it makes, and whether it is marketed for medical or pesticidal use. Most importers need standard Customs and Border Protection (CBP) entry documents, while some products may also trigger Food and Drug Administration (FDA) or Environmental Protection Agency (EPA) requirements.
An air purifier is a device that processes air through a filtration system to remove contaminants and improve the quality of air in an indoor area. They’re effective at removing mold spores, irritants, and foul odors.
Importers who want to bring air purifiers into the U.S. must abide by regulations set by the EPA and the FDA, which are enforced by CBP.
The General Rules of Interpretation (GRI) uses the operating principle of a device in determining its HTS classification. Technical attributes that define the operating principle of an air purifier include the following:
Importers should request technical specifications from their suppliers to inform the tariff classification process. Even if the supplier claims they know the HTS code for their own goods, it’s the importer of record’s (IOR) responsibility to get it right, and the IOR should partner with a broker to verify any HTS codes prior to importing.
HTS classification is governed by the GRI, which are concerned with three main points when it comes to assigning a commodity its correct HTS code:
Air purifiers are classified in chapter 84 of the HTS, which covers machinery, mechanical appliances, and electrical equipment.
CBP doesn’t have any specific regulations on the importation of air purifiers, but they require importers or their agents to submit documentation for each import transaction. This helps them identify the details of your product and charge you the correct duty rate.
You will also need to take into consideration the ISF Filing requirement for shipments arriving via ocean. This document has to be submitted no fewer than twenty-four hours before cargo is loaded onto its vessel.
Failure to submit this critical document at the appropriate time can result in a fine up to $5,000 and seizure of your cargo.
The air purifier importer will also need documents that support HTS classification and the purifier’s country of origin. Manufacturing records, product specification sheets, and detailed transit records for all raw materials and components all contain information about material percentages, product function, and where its constituent parts were made.
CBP uses these documents to verify the product’s HTS classification and, by extension, the accuracy of duties estimated on an importer’s entry form.
Mistakes in HTS classification can lead to fines, customs holds, and other punitive actions from CBP. It’s easy for inexperienced importers to make mistakes during tariff classification.
For instance, an importer asked for a binding ruling from CBP regarding how to classify an air purifier. The purifier was designed to take air into a chamber where it would be filtered by a plant supplied by the owner, and the “purified” air would then be expelled.
However, since the air purifier did not include any native filtration elements, CBP’s final ruling was that the device would be more accurately classified as a fan rather than an air purifier, and would carry a duty rate of 2.3% rather than the free rate of duty which purifiers are subject to.
However, because the device lacked built-in filtration elements, CBP classified it as a fan instead of an air purifier. This classification resulted in a 2.3% duty rate rather than the duty-free treatment available for air purifiers.
Any importer who is uncertain about the Section 232 status of their commodities should consult with a customs broker prior to purchase, as the regulations governing Section 232 applications are heavily nuanced.
Duty treatment depends on the product’s HTS classification, country of origin, and any additional trade measures in effect on the entry date. Because surcharge programs and trade remedies can change, importers should verify current duty treatment against the HTS, CBP guidance, and any applicable Section 301, Section 232, or temporary surcharge measures before shipment.
Assume an importer is bringing 100 air purifier units into the United States. The importer is sourcing the purifiers from Vietnam. The HTS shows no rate of duty, but the 10% Section 122 tariff applies.
If we assume the purifiers are valued at $100.00 a piece, the shipment value is $10,000 ($100 x 100 units). We can then multiply the shipment value of $10,000 x .01 and multiply the answer by 10 to determine duties owed with a 10% tariff rate.
We now have the shipment value and estimated duties. Assuming the air purifiers are being shipped via ocean liner, the importer will also owe the harbor maintenance fee (HMF) and merchandise processing fee (MPF) during customs clearance.
This gives us an HMF of $125 and an MPF of $346.40. We can now estimate the duties that the importer will owe:
These fees do not include freight shipping charges, which should also be part of any landed cost calculation.
Another fee that isn’t included is Section 301 tariffs, which apply to air purifiers imported from the People’s Republic in China.
Air purifier importers need to be aware of regulations from two main Partner Government Agencies (PGA) of CBP:
FDA issues matter when the product is a medical device or a radiation-emitting electronic product, while EPA rules matter when the product makes pesticidal claims regulated under FIFRA.
Air purifiers are commonly used for medical purposes. If this is how your products will be used, then you’ll need to follow the FDA’s radiation-emitting medical device regulations.
Nonmedical purifiers that are intended to remove air-borne pesticides will be regulated by the EPA. This agency wants to ensure your devices will be safe for the environment and any consumers that use it.
Imported air purifiers intended for medical use are regulated by the FDA. Since these products produce a small amount of electromagnetic radiation, they’ll be considered a Class II radiation-emitting medical device. As a result, you’ll need to follow the FDA’s regulations for importing these products.
First, you must ensure the manufacturer meets the FDA’s requirements:
Entry information about your air purifiers will have to be sent to CBP using their Automated Commercial Environment (ACE) system.
The details you provide will be transferred electronically to the FDA:
You’ll need to submit a Declaration of Products Subject to Radiation Control Standards, also known as a Form FDA 2877. This document should be sent to the FDA when your products enter the country.
The EPA will require you to complete a few different requirements before you can bring your air purifiers into the country.
FIFRA is a federal law that’s overseen by the EPA to protect consumers from pesticides. If your air purifier claims to kill, inactivate, entrap, or suppress pesticides, it will be subject to FIFRA labeling.
FIFRA labeling requirements include:
If you don’t already have an EPA Company Number, you’ll need to obtain one. You can do this by accessing and completing the Company Number Generator application.
During this process, you’ll need to provide detailed information on your place of business:
After completing the application, you’ll need to attach a signed letter to a company letterhead. You’ll also need to establish an official address with the EPA. After finishing these two steps, you’ll receive a Company Number, this is used to identify your company to the EPA as an importer.
You can then move on to obtaining an EPA establishment number. To get your EPA establishment number, you’ll need to complete an EPA Form 3540-8 and submit it to a regional office. The document can be sent electronically or printed out and physically mailed.
Before your air purifiers arrive in the U.S., you’ll need to submit an EPA Form 3540-1. This applies to all purifiers, regardless of if they claim to remove pesticides or not. The document must be sent to CBP before any pesticide-related devices can be shipped into the United States. Failure to comply with these regulations could have serious ramifications.
Trade relations between the U.S. and China have been unstable at times, especially since 2018 with the introduction of the Section 301 tariffs. Importers must be diligent to research the state of tariffs on imports from China prior to purchasing goods from this trading partner, as they’re often subject to tariffs that don’t apply to other countries.
According to CBP ruling, air purifiers will receive a 25% ad valorem tax. This tax will be in addition to the standard duty rate that’s already applied to your products.
Despite the Section 301 Tariffs imposed on China, the U.S. still imports a considerable amount of air purifiers from this country. If you choose to source from this country, be sure to brush up on these restrictions.
The amount of time a shipment spends in transit, along with port congestion, impacts the overall time it takes between ordering and receiving an imported shipment. However, there is an order in which paperwork should be submitted and the actions CBP undertakes during the clearance process.
Once an importer has purchased goods and arranged for their transportation to the U.S., the order of events is as follows:
Completing these steps correctly ensures a smooth clearance process.
Customs holds occur when CBP has reason to suspect a shipment needs to be pulled aside due to missing and/or inconsistent paperwork, or they have reason to suspect it contains prohibited goods.
Specifically, CBP may hold a shipment if:
Importers can prevent customs holds by ensuring their entry summaries, ISFs, and other customs paperwork is consistent with information provided on shipping documents and invoices. Working through a customs broker with day-to-day experience clearing shipments through customs can also reduce the likelihood of an importer’s goods being inspected.
