HS 848130 Check (non-return) valves

Quick Answer: Check (non-return) valves imported under HS 848130 enter the UK at 2.00%, the EU at 2.20%, and the US at 5% (MFN). This HS code specifically covers valves designed to allow fluid or gas to flow in only one direction, preventing backflow. These are distinct from other types of valves that may control or stop flow. Importers should be aware that the US offers duty-free entry for certain trading partners, as indicated by the 'Free' rates, while the standard MFN rate is 5%.

How to Classify This HS Code?

```html

What products does HS 848130 cover?

This subheading covers check (non-return) valves, which are mechanical devices designed to allow fluid (liquid or gas) to flow in only one direction. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, these valves automatically close to prevent backflow when the pressure drops or reverses. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm that this category includes a wide range of check valves, such as swing check valves, lift check valves, and ball check valves, regardless of the material of construction, provided their primary function is to prevent reverse flow.

What falls outside HS 848130?

The following products are excluded from HS 848130: valves that are designed to control or regulate flow, such as gate valves, globe valves, or butterfly valves, which are classified under HS 848180. Also excluded are safety valves or relief valves designed to prevent over-pressurization, which fall under HS 848140. Furthermore, taps, cocks, and similar appliances, even if they possess some non-return characteristics, are generally classified elsewhere if their primary function is not solely to prevent backflow, and they may be found in other headings within Chapter 84.

What are common classification mistakes for HS 848130?

A common error is misclassifying valves that have both check valve functionality and flow control capabilities. According to General Rule of Interpretation (GRI) 3(b) of the Harmonized System, when goods are classifiable under two or more headings, the heading that provides the most specific description shall be preferred. Importers may incorrectly classify a valve with a secondary regulating function under 848130 when it should be classified under a heading for regulating valves if that is its principal characteristic, leading to incorrect duty assessments.

How should importers classify products under HS 848130?

The correct procedure for classifying products under HS 848130 involves a thorough examination of the valve's design and primary function. Importers and customs brokers should consult the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC, and review the Explanatory Notes from the WCO. Key considerations include whether the valve's sole purpose is to prevent backflow. If the valve also has a significant regulating or controlling function, further analysis under GRI 3 may be necessary to determine the correct classification.

How is the duty calculated for products under HS 848130?

A stainless steel swing check valve weighing 2.5 kg and declared at a customs value of $150.00 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 $150.00 = $10.50. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule for HS code 848130.9000.

Which trade agreements reduce duties for HS 848130?

Several free trade agreements may reduce the applicable duty rate for HS 848130, including the United States-Mexico-Canada Agreement (USMCA), which can result in Free duty for originating goods from Canada and Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also offers preferential rates for originating goods from member countries like Vietnam. To claim these preferences, a self-certified origin statement for USMCA or a specific certificate of origin for CPTPP is typically required, depending on the importing country's regulations.

FAQ

What are the typical import duty rates for HS code 848130 (Check (non-return) valves) into the United States?

For check (non-return) valves classified under HS code 8481.30, the standard Most Favored Nation (MFN) duty rate for imports into the United States is 2.00% ad valorem. However, preferential rates may apply under various Free Trade Agreements (FTAs). For example, valves originating from Australia (AU) may be eligible for duty-free entry under the Australia-US FTA, provided all rules of origin are met. Importers and customs brokers must verify the country of origin and eligibility for preferential treatment.

How is the import duty for HS 848130 calculated, and can you provide an example?

The import duty for HS code 8481.30 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared value of the goods. For instance, if a shipment of check valves has a customs value of $10,000 and the applicable duty rate is 2.00% ad valorem, the duty amount would be calculated as: $10,000 (Customs Value) × 0.02 (Duty Rate) = $200.00. Some check valves might also have specific duties based on quantity (e.g., per piece), but for 8481.30, ad valorem is most common. Always refer to the most current tariff schedule for the exact calculation basis.

What are the key classification criteria to ensure a valve is correctly classified under HS 8481.30?

To be classified under HS code 8481.30, a valve must function solely as a 'check valve' or 'non-return valve'. This means it is designed to allow fluid (liquid or gas) to flow in only one direction and to prevent backflow. The valve's mechanism typically operates automatically based on the pressure differential of the fluid. Valves that require manual or powered operation to control flow, or those with additional functions beyond preventing backflow, would likely be classified under different HS codes. Consulting the Explanatory Notes to the Harmonized System (HSEN) for Chapter 84 is crucial for precise classification.

Which common trade agreements offer preferential duty rates for HS code 8481.30, and what documentation is typically required?

Several trade agreements can provide preferential duty rates for HS code 8481.30. For imports into the US, agreements like the USMCA (United States-Mexico-Canada Agreement) for goods originating from Canada or Mexico, and other FTAs with countries like Chile (CL) or South Korea (KR), may offer reduced or zero duties. For imports into the UK, the UK Global Tariff lists preferential rates. For example, goods from Australia (AU) might be duty-free. To claim preferential treatment, importers must typically provide a 'proof of origin' document, such as a certificate of origin or a declaration of origin completed by the exporter, certifying that the goods meet the specific rules of origin outlined in the relevant trade agreement. Always verify the specific requirements of the applicable trade agreement.

Are there any specific documentation requirements beyond the commercial invoice and bill of lading for importing check valves under HS 8481.30?

While a commercial invoice, bill of lading, and packing list are standard import documents, specific requirements for HS code 8481.30 can vary by importing country and the nature of the valves. For instance, certain types of valves used in critical applications (e.g., potable water systems, food processing) might require compliance certificates or declarations related to material safety, food-grade standards, or pressure ratings. Importers should consult the specific import regulations of the destination country, often available through their national customs authority website (e.g., US Customs and Border Protection, UK Government's import guidance), to ensure all necessary documentation is prepared to avoid delays or penalties.
