HS 903220 Manostats
Quick Answer: Manostats imported under HS 903220 enter the UK and EU duty-free, while the US imposes a 35% Most Favored Nation (MFN) duty rate. This classification covers pressure regulators and automatic regulating or controlling instruments and apparatus, specifically those designed to control pressure. Importers should be aware of the significant duty differential for the US market. For precise tariff application and potential preferential rates, consulting detailed trade databases like CustomTariffs is recommended. Customs brokers should verify the specific subheadings and any applicable trade agreements for accurate declaration.

How to Classify This HS Code?
What products does HS 903220 cover?
This subheading covers manostats, which are instruments and apparatus for automatically regulating pressure. According to the World Customs Organization's Harmonized System Nomenclature, these devices are designed to maintain a constant pressure, often within a closed system, by adjusting a control element. Official definitions from sources like the USITC Harmonized Tariff Schedule and the EU's TARIC database confirm that this category includes devices like pressure regulators and pressure controllers that operate automatically to ensure a set pressure is maintained.
What falls outside HS 903220?
The following products are excluded from HS 903220: instruments and apparatus for regulating liquid or gaseous flow (which may fall under 903289), manually operated pressure gauges (typically classified under 902620), and pressure switches that are primarily designed for electrical control rather than pressure regulation (often classified under 8536). Devices that measure pressure but do not automatically regulate it are also excluded, such as simple pressure gauges or barometers.
What are common classification mistakes for HS 903220?
A common error is misclassifying pressure switches that have an electrical output for control purposes but are not primarily automatic pressure regulators. According to General Interpretative Rule 1, classification is determined by the terms of the headings and any relative section or chapter notes. Importers may incorrectly classify these as electrical apparatus under Chapter 85 if they focus solely on the electrical switching function rather than the primary function of automatic pressure regulation.
How should importers classify products under HS 903220?
The correct procedure for classifying products under HS 903220 involves a thorough examination of the product's primary function and technical specifications. Importers and customs brokers should consult the official tariff schedules of the importing country, such as the USITC HTS or the UK Trade Tariff, and review the explanatory notes for Heading 9032. Confirming that the device automatically regulates pressure is paramount, distinguishing it from mere pressure measurement or manual control devices.
How is the duty calculated for products under HS 903220?
A specific model of a pneumatic pressure regulator for industrial use, weighing 0.5 kg and declared at a customs value of $150 USD, would attract a US duty of $10.50. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, applied to the declared customs value: 7.0% of $150 USD = $10.50. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule.
Which trade agreements reduce duties for HS 903220?
Several free trade agreements may reduce the applicable duty rate for HS 903220, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying originating goods from Canada and Mexico. The EU-UK Trade and Cooperation Agreement also offers preferential rates, potentially Free, for qualifying goods originating from the EU or UK. To claim these preferences, a self-certified origin statement is typically required for USMCA, while an EUR.1 movement certificate or an origin declaration may be needed for EU/UK preferences, depending on the specific circumstances and value.

FAQ
What are the general import duty rates for HS code 903220 (Manostats)?
The Most Favored Nation (MFN) duty rate for HS code 903220, which covers manostats (pressure reducers), is 3.5% ad valorem in the United States. Many other countries, such as those in the European Union and the United Kingdom, offer duty-free access under their standard tariff schedules (0.00%). It is crucial to consult the specific tariff schedule of the importing country for the definitive rate applicable to your shipment.
How is the duty for manostats under HS 903220 calculated?
The duty for manostats is typically calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the goods. For example, if the MFN duty rate is 3.5% and you import manostats valued at $10,000, the duty would be $10,000 \times 0.035 = $350. Some countries may also have specific excise duties or taxes applied in addition to the customs duty.
What are the classification criteria for goods to be classified under HS 903220?
HS code 903220 specifically covers 'Manostats'. This includes devices designed to automatically reduce and maintain a fluid (liquid or gas) pressure at a predetermined lower value, regardless of variations in the higher inlet pressure. Key classification criteria include the device's function of pressure reduction and regulation, and its application in controlling fluid pressure systems. It is distinct from simple pressure gauges or valves that do not actively regulate pressure.
Are there preferential duty rates available for manostats (HS 903220) under trade agreements?
Yes, preferential duty rates may be available depending on the origin of the manostats and the trade agreements in place between the exporting and importing countries. For instance, goods originating from countries with a Free Trade Agreement (FTA) with the United States, such as Canada or Mexico under USMCA, may qualify for duty-free entry (0.00%). Similarly, goods imported into the EU or UK from partner countries under specific trade pacts might also benefit from reduced or eliminated duties. Importers must ensure they meet all rules of origin and have the necessary proof of origin documentation.
What documentation is typically required for importing manostats under HS 903220?
Standard documentation for importing manostats (HS 903220) includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; a bill of lading or air waybill; and a customs declaration. Depending on the country of import and the specific trade agreement, a Certificate of Origin may be required to claim preferential duty rates. It is also advisable to have technical specifications or datasheets that confirm the product's function as a manostat to support the HS classification.
