HS 848110 Pressure-reducing valves

Quick Answer: Pressure-reducing valves imported under HS 848110 enter the UK at 2.00%, the EU at 2.20%, and the US at 2% (MFN) or free for certain trade agreements. This classification covers valves designed to automatically reduce a higher inlet fluid pressure to a lower, stable outlet pressure. These are crucial components in plumbing, industrial processes, and gas systems to protect downstream equipment and ensure safe operation. Importers should verify specific trade agreement eligibility for US entry to potentially benefit from duty-free status. CustomTariffs aggregates this data, highlighting the importance of checking specific tariff lines within each jurisdiction for precise duty application and potential preferential treatment.

How to Classify This HS Code?

What products does HS 848110 cover?

This subheading covers pressure-reducing valves, which are mechanical devices designed to automatically reduce a higher inlet fluid or gas pressure to a lower, controlled outlet pressure. According to the World Customs Organization's Harmonized System Nomenclature, these valves are essential for regulating flow and maintaining stable downstream pressure in various industrial and domestic applications. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this category includes valves that operate automatically without external power, primarily by the force of the fluid or gas itself.

What falls outside HS 848110?

The following products are excluded from HS 848110: pressure relief valves, which are designed to open at a specific pressure to prevent over-pressurization and then close when the pressure drops, and safety valves, which are a type of pressure relief valve. Also excluded are manual shut-off valves, control valves that require external power or complex electronic control systems, and check valves that only allow flow in one direction. For instance, a simple ball valve or a solenoid valve would not be classified under this subheading.

What are common classification mistakes for HS 848110?

A common error is misclassifying pressure regulators that incorporate additional features, such as integrated filters or pressure gauges, under this subheading. According to General Interpretative Rule 3(b) of the Harmonized System, when goods are presented in sets for retail sale, classification is determined by the component that gives them their essential character. If the primary function of the assembly is not solely pressure reduction, it may fall under a different heading. Importers must carefully assess the main function of the entire product.

How should importers classify products under HS 848110?

The correct procedure for classifying products under HS 848110 involves a thorough examination of the product's design, function, and intended use. Importers and customs brokers should consult the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and review the explanatory notes for Heading 8481. It is crucial to determine if the valve's primary function is to automatically reduce and regulate pressure. If the product is a component of a larger machine, its classification may be affected by the classification of the machine itself.

How is the duty calculated for products under HS 848110?

A Watts N45BU pressure reducing valve for residential plumbing, weighing 0.5 kg and declared at a customs value of $50 USD, would attract a US duty of $1.50. This is calculated using the Most Favored Nation (MFN) duty rate of 3.0% ad valorem, applied to the declared customs value ($50 USD × 0.03 = $1.50). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule of the United States (HTSUS) for subheading 8481.10.0000.

Which trade agreements reduce duties for HS 848110?

Several free trade agreements may reduce the applicable duty rate for HS 848110, 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 Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also offers preferential rates, potentially Free, for originating goods from member countries like Japan and Vietnam. To claim these preferences, importers typically require a self-certified origin statement or a certificate of origin, depending on the specific agreement and jurisdiction.

FAQ

What are the typical import duty rates for HS code 848110 (Pressure-reducing valves)?

The Most Favored Nation (MFN) duty rate for HS code 848110, 'Pressure-reducing valves', is generally 2.00% ad valorem in the United States. However, preferential rates apply under various trade agreements. For example, imports from Australia (AU), Canada (CA), Chile (CL), South Korea (KR), and Singapore (SG) may have duty rates as low as Free (0.00%). It is crucial to consult the latest Harmonized Tariff Schedule of the United States (HTSUS) for the specific country of origin and applicable duty rate. For the European Union, consult the TARIC database, and for the UK, the UK Trade Tariff.

How is the duty calculated for HS code 848110, and can you provide an example?

The duty for HS code 848110 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For example, if a shipment of pressure-reducing valves has a declared customs value of $10,000 USD and the applicable MFN duty rate is 2.00%, the import duty would be calculated as: $10,000 (value) × 0.02 (duty rate) = $200.00. Some valves may also be subject to specific duties based on quantity, but for 848110, ad valorem is most common.

What are the key classification criteria for pressure-reducing valves under HS code 848110?

HS code 848110 specifically covers 'Pressure-reducing valves'. The primary classification criterion is the valve's function: to automatically reduce a higher inlet pressure to a lower, constant outlet pressure, irrespective of variations in the inlet pressure or flow. These valves are typically used in fluid systems (liquids or gases) to maintain a stable downstream pressure. Valves that primarily control flow or shut off flow, without the specific function of pressure reduction, would fall under different subheadings within HS 8481.

What documentation is typically required for importing pressure-reducing valves (HS 848110)?

Standard import documentation for HS code 848110 includes a commercial invoice detailing the value, quantity, and description of the valves; a packing list; and a bill of lading or air waybill. Depending on the country of origin and destination, a certificate of origin may be required to claim preferential duty rates under trade agreements. For certain applications, especially those involving potable water or specific industrial standards, manufacturers might provide technical specifications or compliance certificates that importers should be prepared to present.

Which common trade agreements offer preferential duty rates for HS code 848110 into the United States?

Several trade agreements provide preferential duty rates for pressure-reducing valves (HS 848110) imported into the United States. Notable agreements include the United States-Mexico-Canada Agreement (USMCA), which often grants duty-free entry for goods meeting Rules of Origin; the Central America-Dominican Republic-United States Free Trade Agreement (CAFTA-DR); and bilateral agreements with countries like Chile, Singapore, and South Korea. Importers must ensure the valves meet the specific Rules of Origin for the relevant trade agreement and obtain a valid Certificate of Origin to claim these benefits.
