How to Classify This HS Code?
What products does HS 730640 cover?
This subheading covers welded tubes, pipes, and hollow profiles of circular cross-section, manufactured from stainless steel. According to the World Customs Organization's Harmonized System Nomenclature, this category specifically excludes seamless tubes and pipes. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that the defining characteristics are the welded construction, circular shape, and the material composition of stainless steel, which typically contains a minimum of 10.5% chromium.
What falls outside HS 730640?
The following products are excluded from HS 730640: seamless tubes and pipes of stainless steel, which are classified under HS 730640; tubes and pipes of other ferrous metals (e.g., carbon steel); tubes and pipes of non-ferrous metals (e.g., aluminum or copper); and profiles of non-circular cross-section, even if made of stainless steel and welded. For instance, square or rectangular stainless steel welded tubes would fall under a different subheading within HS 7306.
What are common classification mistakes for HS 730640?
A common error is misidentifying the material as stainless steel when it is a different type of steel alloy, or failing to distinguish between welded and seamless construction. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. Importers may also incorrectly classify products based solely on their end-use rather than their objective characteristics, leading to misclassification under headings like 7307 (tube or pipe fittings).
How should importers classify products under HS 730640?
The correct procedure for classifying products under HS 730640 involves a systematic approach. First, determine if the product is a tube, pipe, or hollow profile. Second, verify that it is of circular cross-section. Third, confirm that the construction is welded, not seamless. Finally, ascertain that the material is indeed stainless steel, typically by reviewing the manufacturer's specifications or material certificates. Consulting the relevant tariff schedule, such as the USITC HTS or the UK Trade Tariff, is crucial for accurate classification.
How is the duty calculated for products under HS 730640?
A 10-meter length of 304 stainless steel welded pipe, with an outer diameter of 50mm and a wall thickness of 2mm, declared at a customs value of $150 USD, would attract a US duty. Assuming a Most Favored Nation (MFN) duty rate of 2.5% ad valorem, the duty would be $3.75 (2.5% × $150). This calculation is based on the value and the MFN rate published in the USITC Harmonized Tariff Schedule, HTSUS, under subheading 7306.40.5005.
Which trade agreements reduce duties for HS 730640?
Several free trade agreements may reduce the applicable duty rate for HS 730640, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating stainless steel tubes and pipes from Canada and Mexico can enter the US duty-free. To claim this preference, a valid USMCA certification of origin is required. Additionally, the Generalized System of Preferences (GSP) may offer reduced or duty-free access for originating goods from certain developing countries, requiring a GSP Form A.

FAQ
What are the typical import duty rates for HS code 730640 (Other, welded, of circular cross-section, of stainless steel)?
Import duty rates for HS code 730640 vary significantly by importing country. For example, under the U.S. Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) duty rate is 3.6% ad valorem. In the European Union, under the TARIC system, the rate can be 0.00% ad valorem for goods originating from certain countries under preferential trade agreements, but may be higher for others. The UK Trade Tariff also shows varying rates, often around 0.00% or Free for goods from countries with specific trade agreements, but can be up to 11% ad valorem for others. Always consult the specific tariff schedule of the importing country for the applicable rate.
How is the duty calculated for HS 730640 if the duty rate is 3.6% ad valorem?
The duty is calculated based on the declared customs value of the imported goods. For instance, if you import 1,000 kilograms of stainless steel welded tubes classified under HS 730640 with a declared customs value of $5,000 USD, and the MFN duty rate is 3.6% ad valorem, the duty amount would be calculated as: 3.6% of $5,000 = 0.036 * $5,000 = $180 USD. Some countries may also apply specific duties based on weight or other units, in addition to or instead of ad valorem duties. Always verify the duty calculation basis with the importing country's customs authority.
What specific criteria define goods under HS code 730640?
HS code 730640 specifically covers 'Other' welded tubes and pipes of circular cross-section, made of stainless steel. The key classification criteria are: 1. Material: Must be of stainless steel. 2. Construction: Must be welded (as opposed to seamless). 3. Shape: Must have a circular cross-section. 4. Residual category: It falls under 'Other' within the broader category of welded tubes and pipes of iron or steel (7306), meaning it's not specifically covered by other subheadings within 7306 that might have different characteristics (e.g., specific diameters, wall thicknesses, or surface treatments).
What documentation is typically required for importing goods under HS code 730640?
Standard documentation for importing goods under HS code 730640 generally includes a commercial invoice, packing list, and bill of lading or air waybill. Crucially, you will need a certificate of origin to claim preferential duty rates under trade agreements. A mill test certificate or material certificate may also be required to verify that the tubes are indeed made of stainless steel and meet specified standards, as per the importing country's regulations and the specific requirements of the HS code. Importers and customs brokers should always confirm the precise documentation needs with the customs authority of the destination country.
Which common trade agreements might offer preferential duty rates for HS code 730640?
Preferential duty rates for HS code 730640 are often available through Free Trade Agreements (FTAs) and other preferential trade arrangements. For example, goods of stainless steel originating from countries that are signatories to the United States-Mexico-Canada Agreement (USMCA) may benefit from reduced or zero duties when imported into the U.S., Canada, or Mexico, provided they meet the rules of origin. Similarly, the EU has numerous FTAs with countries worldwide that can reduce or eliminate duties on goods like those classified under 730640. The UK also has a network of trade agreements post-Brexit. To claim these benefits, importers must possess a valid certificate of origin and ensure the goods meet the specific rules of origin stipulated in the relevant trade agreement.
