HS 841350 Other reciprocating positive displacement pumps

Quick Answer: Other reciprocating positive displacement pumps imported under HS 841350 enter the UK duty-free, the EU at 1.70% ad valorem, and the US at rates ranging from Free to 35% ad valorem. This classification covers pumps that operate by trapping a fixed volume of fluid and forcing (displacing) it into the discharge pipe, utilizing a back-and-forth motion of a piston, plunger, or diaphragm. Examples include piston pumps and diaphragm pumps used in various industrial and domestic applications. Importers should consult specific tariff lines within this code for precise duty rates and potential preferential trade agreements. According to CustomTariffs data, significant variations exist across major trading blocs, necessitating careful classification and duty verification.

How to Classify This HS Code?

What products does HS 841350 cover?

This subheading covers other reciprocating positive displacement pumps, as defined by the World Customs Organization's Harmonized System Explanatory Notes. These pumps operate by a reciprocating motion of a piston, plunger, or diaphragm within a cylinder or chamber to displace a fixed volume of fluid. Examples include piston pumps, plunger pumps, and diaphragm pumps not specifically covered elsewhere in heading 8413. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database provide further detail on the specific types of pumps classified here, excluding those with rotary action or those designed for specific applications like fuel injection.

What falls outside HS 841350?

The following products are excluded from HS 841350: pumps that are not of the reciprocating positive displacement type, such as centrifugal pumps (HS 841370), gear pumps (HS 841360), or screw pumps. Also excluded are pumps for liquids, whether or not fitted with a measuring device, which are specifically designed for use in internal combustion engines (HS 841330), and hand-operated pumps (HS 841320). Furthermore, pumps that are integral parts of larger machines or appliances, where their primary function is secondary to the main machine, may be classified with the machine itself under General Rule of Interpretation 1.

What are common classification mistakes for HS 841350?

A common error is misinterpreting the "reciprocating positive displacement" mechanism. Importers may mistakenly classify rotary pumps, such as gear or vane pumps, under this subheading. Another frequent mistake involves confusing pumps designed for specific applications, like those for fuel injection systems (often classified under HS 841330), with general-purpose reciprocating pumps. Adherence to the Explanatory Notes and the General Rules of Interpretation (GRIs), particularly GRI 1 and GRI 3, is crucial to avoid misclassification.

How should importers classify products under HS 841350?

The correct procedure for classifying products under HS 841350 involves a thorough examination of the pump's operational mechanism and intended use. Importers and customs brokers should consult the WCO Harmonized System Explanatory Notes, the USITC HTS, and the EU TARIC database for precise definitions. Key factors include confirming the reciprocating action of a piston, plunger, or diaphragm and ensuring the pump is not specifically excluded by a more precise subheading or by virtue of being an integral part of another article.

How is the duty calculated for products under HS 841350?

A piston-type industrial pump weighing 50 kg and declared at a customs value of $2,500 USD would attract a US duty of $125.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, as published in the USITC Harmonized Tariff Schedule (HTS) for HS code 841350. The calculation is: 5.0% × $2,500 USD = $125.00. It is essential to verify the specific duty rate applicable at the time of importation, as these can change.

Which trade agreements reduce duties for HS 841350?

Several free trade agreements may reduce the applicable duty rate for HS 841350, including the United States-Mexico-Canada Agreement (USMCA) and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). Under USMCA, pumps originating from Canada or Mexico may be eligible for a duty rate of Free, provided a valid self-certified origin statement is submitted. Similarly, pumps originating from CPTPP member countries may also qualify for preferential duty rates, often Free, contingent upon submission of appropriate origin documentation like a Certificate of Origin.

FAQ

What are the typical import duty rates for HS code 841350 (Other reciprocating positive displacement pumps)?

The Most Favored Nation (MFN) duty rate for HS code 841350 in the United States is 0.00%. However, duty rates can vary significantly based on the country of origin and applicable trade agreements. For example, under the Generalized System of Preferences (GSP), certain developing countries may receive duty-free entry. Importers should always verify the specific rate applicable to their shipment by consulting the USITC Harmonized Tariff Schedule (HTS) and considering any preferential trade agreements. For other jurisdictions, such as the EU (TARIC) or UK (UK Trade Tariff), rates may differ and can be subject to specific trade arrangements.

How is HS code 841350 defined, and what distinguishes 'other' reciprocating positive displacement pumps?

HS code 841350 falls under Chapter 84 of the Harmonized System, which covers nuclear reactors, boilers, machinery and mechanical appliances. Specifically, heading 8413 covers 'Pumps for liquids, whether or not fitted with a measuring device; liquid elevators'. Subheading 8413.50 is for 'Other reciprocating positive displacement pumps'. This classification applies to pumps that operate by the reciprocating motion of a piston, plunger, or diaphragm within a cylinder or chamber, displacing a fixed volume of liquid with each stroke, and are not specifically covered by other more specific subheadings within 8413 (e.g., hand pumps, fuel or oil pumps of a kind used on internal combustion engines, etc.). The key is the reciprocating action and positive displacement mechanism.

What documentation is typically required when importing pumps classified under HS 841350?

When importing pumps classified under HS code 841350, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; and a bill of lading or air waybill. Depending on the pump's intended use and origin, additional documentation might be necessary. For instance, if the pump is for industrial use, a manufacturer's declaration or technical specifications may be requested by customs. If claiming preferential duty rates under a trade agreement, a certificate of origin is crucial. It is advisable for importers and customs brokers to consult the specific import regulations of the destination country and the product's origin.

How is the import duty for HS 841350 calculated, and can you provide an example?

The import duty for HS code 841350 is typically calculated based on either an ad valorem rate (a percentage of the declared value of the goods) or a specific rate (a fixed amount per unit of quantity). For example, if the MFN duty rate for a specific pump classified under 841350 is 1.70% ad valorem, and the declared customs value of the shipment is $10,000, the duty would be calculated as: $10,000 (Customs Value) × 0.0170 (Duty Rate) = $170.00. If there were a specific duty component, such as $0.50 per piece, and you imported 500 pieces, the specific duty would be 500 × $0.50 = $250.00. The importer would pay the higher of the two, or both if it's a compound duty. Always refer to the official tariff schedule for the exact duty calculation basis.

Which common trade agreements might offer preferential duty rates for HS code 841350?

Several trade agreements can impact duty rates for HS code 841350. For imports into the United States, the Generalized System of Preferences (GSP) offers duty-free entry for eligible goods from designated developing countries. Free Trade Agreements (FTAs) such as the USMCA (United States-Mexico-Canada Agreement) may also provide preferential or zero duty rates for pumps originating from Canada or Mexico, provided they meet the rules of origin. Other countries have their own networks of FTAs and preferential schemes. For instance, the UK has various trade agreements post-Brexit, and the EU has its network of association and free trade agreements. Importers must verify if their goods qualify for preferential treatment under any applicable trade agreement by obtaining a valid Certificate of Origin.
