HS 730799 Other
Quick Answer: Iron or steel tube or pipe fittings imported under HS 730799 enter the UK duty-free, the EU at 3.70% ad valorem, and the US at 3.2% ad valorem under the MFN rate. This residual classification applies to fittings of iron or steel not specifically covered by other headings within Chapter 73, such as those for welding, threading, or flanging. Importers should verify specific product characteristics against detailed tariff schedules to ensure correct classification, as variations in material, construction, or intended use can lead to different HS codes. CustomTariffs aggregates this data, highlighting the importance of precise classification for accurate duty assessment across jurisdictions.

How to Classify This HS Code?
What products does HS 730799 cover?
This subheading covers "other" fittings and parts of iron or steel, not elsewhere specified within heading 7307. According to the World Customs Organization's Harmonized System Nomenclature, this category is for items that do not fit the more specific descriptions of other subheadings within 7307, such as threaded or non-threaded couplings, elbows, and tees. For example, it can include specialized clamps, brackets, or connectors made of iron or steel used in piping systems, provided they are not specifically classified elsewhere. USITC and EU TARIC definitions confirm this residual nature, emphasizing that classification here is only appropriate after all other possibilities within the heading have been exhausted.
What falls outside HS 730799?
The following products are excluded from HS 730799: fittings and parts of iron or steel that are specifically enumerated in other subheadings of heading 7307, such as threaded couplings (7307.11), elbows, and tees (7307.19). Also excluded are items that are not considered "fittings" or "parts" of piping systems, like structural components or general hardware not designed for fluid conveyance. For instance, a steel bracket used for mounting machinery, or a steel bolt not intended for joining pipe sections, would be classified under different headings, such as Chapter 73 for iron and steel articles or Chapter 83 for miscellaneous articles of base metal.
What are common classification mistakes for HS 730799?
A common error is classifying items under HS 730799 when they should be placed in more specific subheadings within heading 7307 or even in other headings entirely. This often occurs due to a misunderstanding of the General Rules for the Interpretation of the Harmonized System (GRI), particularly GRI 3(c), which states that goods are to be classified under the heading which occurs last in numerical order among those which equally merit consideration. Importers may incorrectly assign items to this residual category without thoroughly examining the specific characteristics and intended use against more precise descriptions, leading to misclassification of specialized pipe connectors or non-pipe related steel hardware.
How should importers classify products under HS 730799?
The correct procedure for classifying products under HS 730799 involves a systematic approach. First, determine if the product is a fitting or part of iron or steel for piping systems. Second, consult the Explanatory Notes to heading 7307 to understand the scope of the heading. Third, meticulously review all preceding subheadings within 7307 to ascertain if a more specific classification exists. Only if the product does not meet the criteria for any other subheading within 7307 should it be considered for 730799. Customs brokers should always verify the precise material composition and intended application with the manufacturer.
How is the duty calculated for products under HS 730799?
A shipment of 1,000 steel pipe clamps, each weighing 0.5 kg, with a total declared customs value of $2,500 USD, would attract a US duty of $125.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared value ($2,500 USD × 5.0% = $125.00). This is calculated using the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 7307.99.0000, which is 5.0% ad valorem.
Which trade agreements reduce duties for HS 730799?
Several free trade agreements may reduce the applicable duty rate for HS 730799, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada or Mexico may enter the US duty-free. For example, steel pipe fittings originating in Canada would be eligible for a 0% duty rate. To claim this preference, a valid USMCA Certificate of Origin is typically required. Additionally, the Generalized System of Preferences (GSP) may offer reduced or duty-free entry for qualifying goods from certain developing countries, often requiring a GSP Form A.

FAQ
What are the typical import duty rates for HS code 730799?
HS code 730799 covers 'Other' fittings of iron or steel, not elsewhere specified. Duty rates can vary significantly by country. For example, under the US Harmonized Tariff Schedule, the general Most Favored Nation (MFN) rate is 3.70% ad valorem. However, preferential rates may apply under trade agreements. For instance, goods from Australia (AU) may enter duty-free. Always consult the specific tariff schedule of the importing country for the most accurate and up-to-date rates.
How is the import duty for HS 730799 calculated, and can you provide an example?
The duty for HS 730799 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared value of the goods. For example, if the MFN duty rate is 3.70% and you import fittings valued at $10,000 USD, the duty would be calculated as $10,000 USD * 3.70% = $370 USD. If a specific duty (e.g., per unit) also applies, the total duty would be the higher of the ad valorem or specific duty, or a combination, depending on the tariff's structure.
What classification criteria distinguish HS 730799 from other fittings in Chapter 73?
HS code 730799 is a residual category for fittings of iron or steel that are not specifically covered by other headings within 7307. This includes fittings like certain types of couplings, adapters, or specialized connectors not otherwise classified under headings such as 7307.11 (cast iron), 7307.19 (other cast iron), 7307.21 (stainless steel elbows, etc.), 7307.22 (other stainless steel), 7307.91 (threaded), or 7307.92 (unthreaded). Proper classification requires a detailed examination of the fitting's material, form, function, and whether it meets the specific criteria of a more narrowly defined HS code.
Which common trade agreements offer preferential duty rates for HS 730799?
Several trade agreements can provide preferential duty rates for goods classified under HS 730799. For example, the United States has agreements with countries like Australia (AU), Chile (CL), and South Korea (KR) that may offer reduced or zero duty rates. The European Union's TARIC system and the UK Trade Tariff also list preferential rates for goods originating from countries with which they have trade agreements. Importers should verify the specific origin of their goods and consult the relevant preferential tariff schedule to determine eligibility.
What documentation is typically required for importing goods under HS code 730799?
Standard documentation for importing goods under HS 730799 generally includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the origin of the goods, a certificate of origin may be required to claim preferential duty rates under a trade agreement. Customs authorities may also request technical specifications, product literature, or safety data sheets to verify the classification and ensure compliance with any applicable import regulations or standards.
