How to Classify This HS Code?
What products does HS 391733 cover?
This subheading covers tubes, pipes, and hoses of plastics, specifically those that are "other" than those reinforced or otherwise combined with other materials. According to the World Customs Organization's Harmonized System Nomenclature, this includes flexible plastic tubing and piping with attached fittings, such as connectors or couplings, which are integral to their function. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these items are typically used for fluid conveyance and are characterized by their plastic construction and the presence of pre-attached fittings, differentiating them from simpler tubing.
What falls outside HS 391733?
The following products are excluded from HS 391733: tubes, pipes, and hoses of plastics that are reinforced, such as with textile materials or metal wire, or are otherwise combined with other materials to enhance their structural integrity or functionality. Also excluded are plastic tubing and piping without any fittings, which would fall under HS 391732. For instance, a flexible plastic hose reinforced with a steel coil, or a rigid PVC pipe sold without any attached connectors, would be classified elsewhere, typically in HS 391731 or HS 391732 respectively.
What are common classification mistakes for HS 391733?
A common error is misinterpreting the term "fittings" or overlooking the "reinforced or otherwise combined with other materials" exclusion. For example, importers might incorrectly classify a plastic hose with a simple crimped-on metal ferrule as having a fitting under 391733, when the ferrule might be considered a form of combination with another material, potentially leading to classification under a different subheading. Adherence to General Rule of Interpretation (GRI) 1 and 3 is crucial for accurate classification.
How should importers classify products under HS 391733?
The correct procedure for classifying products under HS 391733 involves a two-step process: first, determine if the product is a tube, pipe, or hose of plastics. Second, ascertain if it is not reinforced or otherwise combined with other materials and if it possesses attached fittings. Importers and customs brokers must carefully examine product descriptions, technical specifications, and the physical characteristics of the goods, comparing them against the WCO HS Explanatory Notes and national tariff definitions, such as those found on the USITC HTS or EU TARIC.
How is the duty calculated for products under HS 391733?
A shipment of 1,000 meters of flexible PVC tubing with pre-attached barbed fittings, declared at a customs value of $500 USD, would attract a US duty. Assuming an Most Favored Nation (MFN) duty rate of 3.7% ad valorem for this specific type of product under the USITC Harmonized Tariff Schedule, the duty would be calculated as 3.7% of $500, resulting in a duty amount of $18.50. This calculation is based on the declared value and the applicable tariff rate found in the USITC HTS.
Which trade agreements reduce duties for HS 391733?
Several free trade agreements may reduce the applicable duty rate for HS 391733, including the United States-Mexico-Canada Agreement (USMCA), which can lead to a duty rate of Free for qualifying goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for eligible products from developing countries. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 391733, and how do preferential rates apply?
HS code 391733 covers 'Other tubes, pipes and hoses, of plastics, not reinforced or otherwise combined with other materials, with fittings'. The Most Favored Nation (MFN) duty rate can vary by country. For example, the US applies a 3.1% ad valorem duty. However, preferential rates under Free Trade Agreements (FTAs) can significantly reduce or eliminate these duties. For instance, under certain agreements, countries like Australia (AU), Canada (CA), Chile (CL), or South Korea (KR) may benefit from a 'Free' duty rate (0%). Importers should always consult the specific tariff schedule of the importing country and verify eligibility for preferential treatment based on the origin of the goods and the applicable trade agreement.
What specific criteria define 'fittings' for HS code 391733, and how does this affect classification?
For HS code 391733, 'fittings' refer to components permanently attached to the plastic tube, pipe, or hose that are designed to connect it to other similar items, to machinery, or to a surface. These fittings are typically made of plastic or other materials integrated into the product during manufacturing. Examples include threaded ends, barbed connectors, or molded couplings. If the fittings are not permanently attached, or if the product is reinforced or combined with other materials (e.g., metal wire, textiles), it would likely be classified under a different HS code. Consulting the Explanatory Notes to the Harmonized System (HS) for Chapter 39 provides detailed guidance on the interpretation of 'fittings' and combinations.
What documentation is typically required for importing goods classified under HS 391733?
When importing goods under HS code 391733, standard customs documentation is 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. Crucially, importers must provide a declaration of conformity or a certificate of origin if preferential duty rates are claimed under a Free Trade Agreement. Depending on the importing country's regulations, specific product safety or quality certifications may also be necessary. Customs brokers play a vital role in ensuring all required documents are accurate and complete to avoid delays or penalties.
How is the import duty for HS 391733 calculated, and can you provide an example?
The import duty for HS code 391733 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 3.1% and an importer brings in plastic tubing with fittings valued at $10,000 USD, the duty calculation would be: $10,000 (Customs Value) × 0.031 (Duty Rate) = $310 USD (Import Duty). If the duty were a specific rate (e.g., per kilogram), the calculation would be Rate per Unit × Quantity. Importers must ensure the customs value is correctly declared, including the cost of the goods, insurance, and freight to the port of importation, as this forms the basis for duty calculation.
Which major trade agreements commonly offer reduced or duty-free entry for HS 391733, and what are the implications?
Several major trade agreements can offer reduced or duty-free entry for goods classified under HS 391733. For example, the United States-Mexico-Canada Agreement (USMCA) may provide preferential treatment for goods originating in Canada or Mexico. Similarly, agreements between the EU and countries like Japan, Canada (CETA), or South Korea often include provisions for lower tariffs on plastic products. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also impacts trade for member nations. The implication of these agreements is a significant reduction in landed costs for importers who can prove the goods meet the rules of origin stipulated in the respective agreements. This requires careful documentation, such as a certificate of origin, and understanding the specific tariff classifications and origin criteria for each trade partner.
