HS 391721 Tubes, pipes and hoses, rigid
Quick Answer: Rigid tubes, pipes, and hoses made of plastics enter the UK at 6.00%, the EU at 6.50%, and the US at 3.1% (MFN). This classification specifically covers extruded, rigid conduits of polymers of ethylene, propylene, vinyl chloride, or other plastics, excluding flexible hoses or those with significant metal components. Importers should be aware of potential variations in duty rates based on specific plastic types and origin countries, particularly in the US where preferential rates apply.

How to Classify This HS Code?
What products does HS 391721 cover?
This subheading covers rigid tubes, pipes, and hoses made of plastics, specifically those that are not flexible. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category includes extruded or molded profiles of a tubular shape, intended for the conveyance of fluids or other substances. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that the rigidity is the defining characteristic, distinguishing them from flexible hoses and tubing.
What falls outside HS 391721?
The following products are excluded from HS 391721: flexible tubes, pipes, and hoses, which are classified under HS 391722 or 391723 depending on the plastic material. Also excluded are composite tubes and pipes made of plastics combined with other materials, such as metal reinforcement, unless the plastic is the predominant component. Furthermore, finished articles incorporating these tubes, like garden hoses with fittings already attached, may fall under different headings based on their primary function.
What are common classification mistakes for HS 391721?
A common error is misinterpreting the term "rigid" and classifying semi-rigid or slightly flexible plastic tubing under this subheading. According to General Interpretative Rule 1 of the Harmonized System, classification is determined by the terms of the headings and any relative Section or Chapter Notes. Importers may also incorrectly classify reinforced plastic hoses or those with significant metal components, which should be assessed based on the material providing the essential character.
How should importers classify products under HS 391721?
The correct procedure for classifying products under HS 391721 involves a thorough examination of the product's physical characteristics, particularly its rigidity. Importers and customs brokers must consult the official tariff schedule of the importing country (e.g., USITC HTS, EU TARIC, UK Trade Tariff) and review the explanatory notes for Heading 3917. Confirming that the product is exclusively made of plastics and exhibits no significant flexibility is crucial for accurate classification.
How is the duty calculated for products under HS 391721?
A shipment of 1,000 kilograms of rigid PVC conduit pipes, 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, applied to the declared customs value ($2,500 USD × 0.05 = $125.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 391721.
Which trade agreements reduce duties for HS 391721?
Several free trade agreements may reduce the applicable duty rate for HS 391721, including the United States-Mexico-Canada Agreement (USMCA), which can result in a Free duty rate 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. To claim these preferences, a valid certificate of origin or a self-certified origin statement, as per the specific requirements of the importing jurisdiction, is typically required.

FAQ
What are the typical import duty rates for HS code 391721 (Rigid tubes, pipes and hoses of plastics)?
The Most Favored Nation (MFN) duty rate for HS code 391721 can vary. For example, under the US Harmonized Tariff Schedule, the MFN rate is often around 3.1% ad valorem. However, preferential rates under various trade agreements can significantly reduce or eliminate duties. For instance, goods originating from countries like Australia (AU), Canada (CA), or Mexico (MX) under the USMCA may have a duty rate of Free. Always consult the specific tariff schedule of the importing country and verify the country of origin to determine applicable rates.
How is the import duty for HS code 391721 calculated, and can you provide an example?
The duty calculation for HS code 391721 is typically based on the ad valorem system, meaning a percentage of the declared customs value of the goods. For example, if rigid plastic pipes valued at $10,000 are imported into the U.S. with an MFN duty rate of 3.1%, the duty would be calculated as: $10,000 (Customs Value) × 0.031 (Duty Rate) = $310. Some products under this code might also have specific duties based on weight or other units, but ad valorem is most common. Always confirm the specific duty basis (ad valorem, specific, or compound) with the relevant customs authority.
What are the key classification criteria for goods falling under HS code 391721?
HS code 391721 covers 'Tubes, pipes and hoses, rigid' made of plastics. The primary classification criterion is the rigidity of the product. This means the tubes, pipes, or hoses must maintain their shape under normal handling and storage conditions without significant deformation. They are typically circular in cross-section and designed for conveying fluids or gases. Exclusions often include flexible hoses or tubing, or those with specific functions like electrical conduit, which may fall under different HS codes.
Which common trade agreements offer preferential duty rates for HS code 391721 into the United States?
Several trade agreements provide preferential duty rates for HS code 391721 into the United States. For goods meeting the rules of origin, significant reductions or duty-free entry are often available under agreements such as the United States-Mexico-Canada Agreement (USMCA), which typically grants Free entry for eligible goods from Canada and Mexico. Other agreements, like those with Australia (AU), Chile (CL), or South Korea (KR), may also offer reduced or free rates. Importers must possess valid proof of origin documentation, such as a Certificate of Origin, to claim these benefits.
What documentation is typically required when importing rigid plastic tubes and pipes under HS code 391721?
Standard import documentation for HS code 391721 includes a commercial invoice, packing list, and bill of lading or air waybill. Crucially, to claim preferential duty rates under trade agreements, a valid Certificate of Origin is usually required, demonstrating that the goods meet the rules of origin for that specific agreement. Depending on the importing country and the nature of the plastic material, additional certifications related to safety standards, material composition, or environmental compliance might be necessary. Consulting the importing country's customs authority or a licensed customs broker is advised for a comprehensive list.
