How to Classify This HS Code?
What products does HS 730791 cover?
This subheading covers "other" fittings and parts of iron or steel, not specified or included elsewhere in heading 7307. According to the WCO Harmonized System Explanatory Notes and official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC, this category encompasses a wide array of iron or steel pipe or tubing fittings that do not fit into more specific subheadings. Examples include certain types of clamps, brackets, and specialized connectors not otherwise defined, provided they are made of iron or steel and are designed for use with pipes or tubing.
What falls outside HS 730791?
The following products are excluded from HS 730791: fittings and parts of cast iron (which are classified under 730711 or 730719), and specific types of threaded or flanged fittings of iron or steel (classified under 730792 or 730793). Also excluded are complete pipe systems or assemblies, as well as non-metallic fittings. For instance, plastic pipe fittings or complete, pre-assembled pipe sections with integrated connectors would not fall under this subheading.
What are common classification mistakes for HS 730791?
A common error is misclassifying items that are more specifically described in other subheadings of heading 7307, such as threaded or flanged fittings. Importers may also mistakenly classify complete pipe assemblies or components that are not strictly "fittings" or "parts" of fittings under this code. Adherence to the General Rules for the Interpretation of the Harmonized System (GRI), particularly GRI 1 and GRI 3, is crucial to ensure accurate classification based on the most specific description.
How should importers classify products under HS 730791?
The correct procedure for classifying products under HS 730791 involves a thorough examination of the product's material composition, function, and specific design. Importers and customs brokers must first consult the WCO Harmonized System Explanatory Notes and the relevant national tariff schedule (e.g., USITC HTS, EU TARIC, UK Trade Tariff). If the item is made of iron or steel, is a fitting or part thereof for pipes or tubes, and is not specifically covered by other subheadings within 7307, then 730791 is likely the appropriate classification.
How is the duty calculated for products under HS 730791?
A shipment of 1,000 steel pipe clamps, declared at a customs value of $500 USD, would attract a US duty of $35.00. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, applied to the declared customs value ($500 USD × 0.07 = $35.00). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule, where fittings not otherwise specified often carry such rates.
Which trade agreements reduce duties for HS 730791?
Several free trade agreements may reduce the applicable duty rate for HS 730791, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. Additionally, developing countries may benefit from the Generalized System of Preferences (GSP), potentially offering Free entry. Documentation required typically includes a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

FAQ
What is the import duty for HS code 730791?
HS code 730791 covers "Other" "tube or pipe fittings of iron or steel", specifically those "threaded or otherwise connected". The Most Favored Nation (MFN) duty rate for this classification in the United States is 3.70% ad valorem. However, preferential rates may apply under various trade agreements. For example, under the US-Korea Free Trade Agreement (KORUS), the duty rate is Free. It is crucial to consult the latest USITC tariff schedule for the most current rates and any applicable trade agreement provisions.
How is the import duty for HS 730791 calculated, and can you provide an example?
The duty for HS code 730791 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared value of the imported goods. For instance, if you import a shipment of threaded steel pipe fittings valued at $10,000 USD and the MFN duty rate is 3.70%, the import duty would be calculated as: $10,000 (value) × 0.0370 (duty rate) = $370.00. Always ensure your declared value is accurate and includes all elements required by customs regulations, such as cost, insurance, and freight (CIF).
What documentation is typically required for importing goods classified under HS 730791?
For imports classified under HS code 730791, standard customs documentation is required. This includes a commercial invoice detailing the description, quantity, value, and origin of the goods; a packing list; and a bill of lading or air waybill. Depending on the origin and specific nature of the fittings, a certificate of origin may be necessary to claim preferential duty rates under trade agreements. Importers should also be prepared to provide technical specifications or product literature if requested by customs to verify classification.
Which trade agreements offer preferential duty rates for HS code 730791, and how can I verify eligibility?
Several trade agreements may offer preferential duty rates for HS code 730791. For example, goods originating from countries like South Korea (under KORUS), Australia, or Chile may enter the US duty-free or at reduced rates. To verify eligibility, importers and customs brokers must: 1. Confirm the country of origin of the imported fittings. 2. Obtain a valid Certificate of Origin from the foreign supplier, which must meet the specific requirements of the relevant trade agreement. 3. Consult the Harmonized Tariff Schedule of the United States (HTSUS) or the specific trade agreement text to confirm the applicable preferential rate and any conditions for its application. For instance, the HTSUS lists 'Free' under column 3 for 'K' (KORUS) for this code, indicating duty-free entry for eligible goods.
What distinguishes HS code 730791 from other pipe fitting classifications?
HS code 730791 falls under the broader category of "Tube or pipe fittings of iron or steel" (7307). Specifically, it covers fittings that are "Other" than those covered by more specific subheadings (like those for cast iron or forged iron/steel). The key differentiator for 730791 is that the fittings are "threaded or otherwise connected". This means fittings that are joined by means of screw threads, or by other connection methods such as flanging, welding, or grooving, and are not specifically classified elsewhere within Chapter 7307, would fall under this residual "Other" category if they are threaded or otherwise connected. Fittings that are simply cut to length or have plain ends without a specific connection mechanism might fall under different subheadings if they exist, or be classified differently based on their primary function if not clearly a fitting.
