HS 730661 Other, welded, of non-circular cross-section

Quick Answer: Tubes, pipes, and hollow profiles of iron or steel, of a non-circular cross-section and welded, enter the UK and EU duty-free, and the US duty-free under the MFN rate. This classification specifically covers welded hollow sections that are not round, oval, or rectangular, such as those with a square or other polygonal shape. Importers should be aware that while the primary duty rates are zero in these major markets, specific end-use or material composition could potentially lead to different classifications or additional duties. CustomTariffs aggregates this data, highlighting the generally favorable duty treatment for this category.

How to Classify This HS Code?

```html

What products does HS 730661 cover?

This subheading covers welded tubes, pipes, and profiles, of iron or steel, that have a non-circular cross-section. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category specifically excludes circular cross-sections. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that items such as square, rectangular, or oval steel tubing, when manufactured by welding, fall under this classification, provided they are not further worked beyond basic finishing.

What falls outside HS 730661?

The following products are excluded from HS 730661: seamless tubes and pipes (classified under 730611 or 730619), tubes and pipes of circular cross-section (classified under 730630), and those made from cast iron or high-speed steel. Additionally, products that have undergone significant further working, such as threading, grooving, or being fitted with flanges, may be classified under more specific headings or subheadings depending on the nature of the additional processing and the final product's primary function, as guided by the General Rules for the Interpretation of the Harmonized System (GRI).

What are common classification mistakes for HS 730661?

A common error is misclassifying welded tubes and pipes of circular cross-section under this subheading; these should be classified under HS 730630. Another mistake involves confusing welded products with seamless ones, which are classified in different headings. Furthermore, importers may incorrectly classify products that have undergone significant further processing, such as being incorporated into a more complex assembly, failing to apply GRI 3 for composite goods or GRI 4 for goods not elsewhere specified, leading to incorrect duty assessments.

How should importers classify products under HS 730661?

The correct procedure for classifying products under HS 730661 involves a systematic approach. Importers and customs brokers must first determine if the product is a tube, pipe, or profile made of iron or steel. Next, they must verify that the manufacturing method is welding and that the cross-section is non-circular. Consulting the WCO HS Explanatory Notes, the specific national tariff schedule (e.g., USITC HTS, UK Trade Tariff), and potentially seeking a binding ruling from customs authorities are crucial steps to ensure accurate classification.

How is the duty calculated for products under HS 730661?

A shipment of 1,000 kilograms of welded rectangular steel tubing, declared at a customs value of $2,500 USD, would attract a US duty of $175.00. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, applied to the declared customs value ($2,500 USD × 0.07 = $175.00). This rate is published in the USITC Harmonized Tariff Schedule (HTS) for subheading 730661.00.00. Note that specific end-use or origin might alter this rate.

Which trade agreements reduce duties for HS 730661?

Several free trade agreements may reduce the applicable duty rate for HS 730661, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada and Mexico can enter the United States duty-free. To claim this preference, a valid USMCA certification of origin is required. Additionally, the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may offer preferential rates for originating goods from member countries like Japan and Singapore, often resulting in a duty rate of Free.

FAQ

What are the typical import duty rates for HS code 730661 (Other, welded, of non-circular cross-section)?

For HS code 730661, the Most Favored Nation (MFN) duty rate in the United States is 0.00% ad valorem. Many other countries also offer duty-free access under various trade agreements. For example, under the US-Korea Free Trade Agreement (KORUS), the rate is Free. It is crucial to consult the specific tariff schedule of the importing country and any applicable trade agreements to confirm the exact duty rate, as rates can change and vary by origin. Always verify with official sources like the USITC Harmonized Tariff Schedule or the EU's TARIC database.

What defines 'non-circular cross-section' for steel tubes and pipes under HS 730661?

For HS code 730661, 'non-circular cross-section' refers to tubes and pipes whose shape is not round. This includes, but is not limited to, square, rectangular, oval, or other polygonal shapes. The key criterion is that the shape deviates from a perfect circle when viewed in cross-section. This classification applies to welded tubes and pipes meeting this geometric characteristic and not specifically classified elsewhere within Chapter 73 of the Harmonized System.

How is the import duty calculated for HS 730661 if a duty were applicable?

Import duty for HS 730661 is typically calculated on an ad valorem basis (a percentage of the declared value of the goods) or sometimes on a specific duty basis (a fixed amount per unit of quantity). For instance, if the MFN duty rate were 3.5% ad valorem and the declared customs value of a shipment of non-circular welded steel pipes was $10,000, the duty would be calculated as: $10,000 (Value) × 0.035 (Duty Rate) = $350.00. If a specific duty applied, such as $0.50 per kilogram, the calculation would be: 500 kg (Net Weight) × $0.50/kg = $250.00. Always refer to the specific tariff schedule for the applicable duty basis and rate.

What documentation is typically required for importing goods classified under HS 730661?

When importing goods under HS code 730661, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list specifying the contents of each package; and a bill of lading or air waybill as proof of shipment. Depending on the country of origin and destination, 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 drawings if the customs authorities require further clarification on the 'non-circular cross-section' or 'welded' nature of the goods.

Which trade agreements commonly provide preferential duty rates for HS 730661?

Many trade agreements offer preferential duty rates, often resulting in duty-free entry, for goods classified under HS 730661. Examples include the United States-Mexico-Canada Agreement (USMCA), where originating goods may benefit from reduced or eliminated duties. The European Union's trade agreements with various countries also often provide preferential treatment. For goods originating in Canada or Mexico and imported into the US, the USMCA typically allows for duty-free entry if rules of origin are met. Importers should consult the specific trade agreement between the exporting and importing countries and ensure compliance with all rules of origin requirements to benefit from these preferential rates.
