HS 730431 Other, of circular cross-section, of iron or non-alloy steel
Quick Answer: Tubes and pipes of iron or non-alloy steel, of circular cross-section, enter the UK duty-free, the EU duty-free, and the US duty-free under their Most Favored Nation (MFN) rates. This classification, HS 730431, specifically covers seamless or welded tubes and pipes made from iron or non-alloy steel that have a round shape. It is crucial for importers and exporters to verify specific product dimensions and steel composition, as these can sometimes lead to sub-classification and different duty rates. CustomTariffs aggregates this tariff data, highlighting the generally favorable duty landscape for these goods across major markets.

How to Classify This HS Code?
What products does HS 730431 cover?
This subheading covers tubes, pipes, and hollow profiles, of circular cross-section, made of iron or non-alloy steel, that are not further worked beyond basic manufacturing processes. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category specifically excludes items with other cross-sections or those made from alloy steel. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm this scope, focusing on seamless or welded products meeting these material and dimensional criteria.
What falls outside HS 730431?
The following products are excluded from HS 730431: tubes and pipes of alloy steel, those with non-circular cross-sections (e.g., square or rectangular), and products that have undergone further working such as threading, grooving, or coating beyond basic finishing. For instance, seamless steel tubes for oil and gas pipelines, often with specialized coatings and dimensions, may fall under different subheadings, and hollow bars of alloy steel are classified elsewhere within Chapter 73.
What are common classification mistakes for HS 730431?
A common error is misclassifying tubes made from alloy steel under this subheading. General Rule of Interpretation (GRI) 1 dictates that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. If a product is made of alloy steel, it must be classified under a heading specific to alloy steel, even if it otherwise meets the description of HS 730431, which is strictly for iron or non-alloy steel.
How should importers classify products under HS 730431?
The correct procedure for classifying products under HS 730431 involves a multi-step process. Importers and customs brokers must first ascertain the material composition, confirming it is iron or non-alloy steel. Second, they must verify the cross-section is circular. Third, they should examine the product's condition, ensuring it has not undergone significant further working. Consulting official tariff schedules like the USITC HTS or EU TARIC for specific product descriptions and any relevant explanatory notes is crucial.
How is the duty calculated for products under HS 730431?
A shipment of 1,000 kilograms of seamless cold-drawn carbon steel tubes (HS 730431) declared at a customs value of $2,500 USD would attract a US duty. Assuming a Most Favored Nation (MFN) duty rate of 2.5% ad valorem, the duty would be $62.50 ($2,500 × 0.025). This calculation is based on the ad valorem principle, where the duty is a percentage of the declared customs value, as published in the USITC Harmonized Tariff Schedule.
Which trade agreements reduce duties for HS 730431?
Several free trade agreements may reduce the applicable duty rate for HS 730431, including the United States-Mexico-Canada Agreement (USMCA), which can provide for duty-free entry for qualifying goods originating from Canada or Mexico. For goods originating in certain developing countries, the Generalized System of Preferences (GSP) may offer reduced or duty-free rates. To claim these preferences, a valid origin declaration or certificate, such as a USMCA certification of origin or a GSP Form A, is typically required by the importing country's customs authority.

FAQ
What are the typical import duty rates for HS code 730431 (Other, of circular cross-section, of iron or non-alloy steel)?
The Most Favored Nation (MFN) duty rate for HS code 730431 is typically 0.00% ad valorem in the United States. However, it's crucial to verify the specific duty rate applicable to your country of origin and the importing country's tariff schedule, as rates can vary significantly. For instance, the EU TARIC system may show different rates based on origin and trade agreements. Always consult the most current official tariff database for the destination country.
How is the import duty for HS 730431 calculated, and can you provide an example?
Import duty for HS 730431 is generally calculated on an ad valorem basis, meaning a percentage of the declared customs value of the goods. For example, if the MFN duty rate is 0.00% and you import 1,000 kilograms of steel tubes valued at $2,000 USD, the duty would be calculated as: 0.00% * $2,000 = $0.00 USD. If a specific rate (e.g., per unit weight) were applicable, the calculation would be Rate per Unit × Quantity. Always confirm the basis of duty calculation (ad valorem, specific, or compound) with the importing country's customs authority.
What are the key classification criteria for steel tubes and pipes under HS code 730431?
HS code 730431 specifically covers 'Other' tubes, pipes, and hollow profiles, of circular cross-section, seamless, of 'iron or non-alloy steel'. Key classification criteria include: 1. Material: Must be iron or non-alloy steel. 2. Cross-section: Must be circular. 3. Construction: Must be seamless (not welded). 4. Application: If the tubes are designed for specific uses (e.g., for railways, tramways, pipes for gas pipelines), they might fall under more specific subheadings. HS 7304.31.00 covers those not falling under more specific categories within 7304.
What documentation is typically required for importing goods classified under HS 730431?
Standard documentation for importing goods under HS 730431 includes: a commercial invoice detailing the value, quantity, and description of the goods; a packing list; a bill of lading or air waybill for transport; and a certificate of origin. Depending on the importing country and the origin of the goods, additional certifications may be required, such as mill test certificates to verify the steel composition and compliance with relevant standards (e.g., ASTM, EN). Importers should always consult the specific import regulations of the destination country.
Do common trade agreements, like USMCA or EU free trade agreements, affect the duty rates for HS code 730431?
Yes, trade agreements can significantly impact duty rates. For example, goods of USMCA origin (Canada, Mexico, United States) may qualify for preferential duty rates, often 0.00%, under the agreement, provided they meet the rules of origin. Similarly, the EU has numerous Free Trade Agreements (FTAs) with various countries that could reduce or eliminate duties on steel products like those under HS 730431. To claim preferential treatment, importers must possess a valid certificate of origin and ensure the goods meet all stipulated rules of origin criteria. Always check the specific provisions of the relevant trade agreement and the importing country's tariff schedule.
