HS 830790 Of other base metal
Quick Answer: Flexible tubing of base metal, not specified elsewhere in Chapter 83, enters the UK duty-free, the EU at 2.70% ad valorem, and the US at 30% ad valorem (MFN). This classification covers a wide array of non-precious metal flexible conduits, such as those made from steel or aluminum, used for various industrial and domestic applications. Importers should be aware of the significant duty rate disparity in the US, which may necessitate exploring preferential trade agreements for reduced rates. According to CustomTariffs data, careful classification is crucial to avoid overpayment of duties.

How to Classify This HS Code?
What products does HS 830790 cover?
This subheading covers flexible tubing and pipes of base metal, not being of precious metal or plated or clad with precious metal, specifically those not made of aluminum or copper. According to the World Customs Organization's Harmonized System Nomenclature, this category encompasses items like steel flexible conduits, stainless steel hoses, and other similar flexible metal tubing used for various industrial, automotive, or plumbing applications, provided they are not specifically classified under other headings or subheadings within Chapter 83. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database provide detailed interpretations for precise classification.
What falls outside HS 830790?
The following products are excluded from HS 830790: flexible tubing and pipes of aluminum (HS 830710), flexible tubing and pipes of copper (HS 830790, specifically for copper), and rigid pipes and tubes of base metal (which are typically classified in Chapter 73 for iron and steel, or Chapter 74 for copper). Additionally, articles of precious metal or those plated or clad with precious metal are excluded, as are composite products where the base metal is not the predominant component by weight or value, or where the function is primarily determined by another material.
What are common classification mistakes for HS 830790?
A common error is misclassifying flexible metal tubing based solely on its end-use rather than its material composition and construction. For instance, a flexible steel hose intended for a specific industrial machine might be mistakenly classified under a machinery heading. General Rule of Interpretation (GRI) 1 states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. If the product is a composite good, GRI 3 principles must be applied to determine the essential character. Incorrectly assuming that all flexible metal tubing falls under this code without considering specific material exclusions is also frequent.
How should importers classify products under HS 830790?
The correct procedure for classifying products under HS 830790 involves a thorough examination of the product's material composition, specifically confirming it is made of base metal other than aluminum or copper. Importers and customs brokers must consult the official tariff schedule of the importing country, such as the USITC Harmonized Tariff Schedule (HTS) or the EU's TARIC database, to verify the exact wording of heading 8307 and subheading 830790. Reviewing relevant Explanatory Notes from the WCO can provide further clarification on the scope and exclusions of this classification.
How is the duty calculated for products under HS 830790?
A shipment of 1,000 meters of stainless steel flexible conduit, weighing 250 kg and declared at a customs value of $5,000 USD, would attract a US duty of $350.00. Assuming a Most Favored Nation (MFN) duty rate of 7.0% ad valorem, the calculation is 7.0% of $5,000 USD, resulting in $350.00. This is calculated using the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 830790.90.00 (other flexible tubing and pipes of base metal).
Which trade agreements reduce duties for HS 830790?
Several free trade agreements may reduce the applicable duty rate for HS 830790, 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. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates for goods from member countries. To claim these preferences, a valid USMCA Certificate of Origin or a CPTPP Certificate of Origin is typically required, depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 830790, covering flexible tubing of other base metal?
The Most Favored Nation (MFN) duty rate for HS code 830790 is typically 3.8% ad valorem. However, preferential duty rates can significantly reduce or eliminate this. For example, under certain trade agreements, the duty rate can be Free (0.00%) for imports from countries like Australia (AU), Canada (CA), Mexico (MX), and South Korea (KR). It is crucial to consult the specific tariff schedule of the importing country and verify eligibility for preferential treatment based on the origin of the goods and applicable trade agreements.
How is the import duty for HS code 830790 calculated, and can you provide an example?
The duty for HS code 830790 is generally calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if the MFN duty rate is 3.8% and the declared value of a shipment of flexible tubing made of aluminum (a base metal other than iron or steel) is $10,000 USD, the import duty would be $10,000 USD × 3.8% = $380 USD. If a specific duty is applicable (e.g., per unit), the calculation would be rate × quantity.
What are the key classification criteria to ensure goods are correctly classified under HS code 830790?
HS code 830790 falls under Chapter 83 of the Harmonized System, which covers 'Miscellaneous articles of base metal'. Specifically, it applies to 'Flexible tubing of base metal, with or without fittings, of iron or steel' (8307.10) and 'Of other base metal' (8307.90). To classify under 830790, the flexible tubing must be made from a base metal other than iron or steel, such as aluminum, copper, nickel, zinc, or their alloys. The tubing's flexibility is a key characteristic. Fittings attached to the tubing do not preclude classification under this code, provided the tubing itself is the primary component and made of a base metal other than iron or steel.
What documentation is typically required for importing goods classified under HS code 830790?
Standard import documentation is generally required for goods classified under HS code 830790. This 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 to claim preferential duty rates if applicable. Depending on the importing country and the specific nature of the base metal tubing, additional certifications or compliance documents related to material safety, environmental standards, or product specifications might be requested by customs authorities.
Which major trade agreements commonly offer preferential duty rates for HS code 830790?
Several major trade agreements can provide preferential duty rates, often reducing them to Free (0.00%), for HS code 830790. Examples include the United States-Mexico-Canada Agreement (USMCA), which can offer preferential rates for goods originating from Canada and Mexico; the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP); and various bilateral free trade agreements the importing country has with nations like South Korea, Chile, or Singapore. Importers and customs brokers must verify the specific rules of origin under each agreement to confirm eligibility for preferential treatment.
