HS 740322 Copper-tin base alloys (bronze)
Quick Answer: Copper-tin base alloys (bronze) imported under HS 740322 enter the UK at 0.00%, the EU at 0.00%, and the US at 1% (MFN), with duty-free entry from various Free Trade Agreement partners. This classification specifically covers unwrought or semi-manufactured forms of bronze, which are alloys where copper is the principal element and tin is the main alloying element. Importers should be aware of the preferential duty rates available for US entry from specific countries, as detailed by the USITC. CustomTariffs aggregates this information, highlighting the importance of verifying origin for optimal duty assessment.

How to Classify This HS Code?
What products does HS 740322 cover?
This subheading covers unwrought or refined copper-tin base alloys, commonly known as bronze, in various forms. According to the World Customs Organization's Harmonized System Nomenclature, this category specifically includes bronze alloys where tin is the principal alloying element. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this code applies to bronze in bars, rods, profiles, wire, plates, sheets, and strip, provided they are primarily composed of copper and tin, with tin being the predominant alloying metal by weight.
What falls outside HS 740322?
The following products are excluded from HS 740322: copper alloys where tin is not the principal alloying element (e.g., brass, which is a copper-zinc alloy), pure copper, and copper powders. Also excluded are finished articles manufactured from bronze, such as bronze castings, sculptures, or components for machinery, which would be classified under their respective headings based on their end-use or material composition. For instance, bronze wire used in electrical cables would fall under Chapter 85, not Chapter 74.
What are common classification mistakes for HS 740322?
A common error is misinterpreting the principal alloying element. HS 740322 specifically denotes copper-tin alloys (bronze). Importers may mistakenly classify copper alloys with other significant alloying elements, such as aluminum bronze (copper-aluminum) or silicon bronze (copper-silicon), under this subheading. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. It is crucial to verify the exact composition of the alloy to ensure correct classification.
How should importers classify products under HS 740322?
The correct procedure for classifying products under HS 740322 involves a multi-step process. First, obtain a detailed technical specification or Certificate of Analysis from the manufacturer that clearly states the elemental composition of the copper alloy. Second, determine the principal alloying element by weight. If tin is the principal alloying element, and the alloy is primarily copper, then HS 740322 is likely applicable. Consult the relevant national tariff schedule, such as the USITC HTS or the UK Trade Tariff, for specific subheadings and any additional notes or exclusions.
How is the duty calculated for products under HS 740322?
A shipment of 1,000 kilograms of bronze rods (HS 740322) declared at a customs value of $15,000 USD would attract a US duty of $750. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($15,000 USD × 0.05 = $750). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule of the United States (HTSUS) for subheading 7403.22.0000.
Which trade agreements reduce duties for HS 740322?
Several free trade agreements may reduce the applicable duty rate for HS 740322, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, eligible bronze products originating from Canada or Mexico can be imported duty-free. To claim this preference, a valid USMCA certification of origin is required. Additionally, preferential rates may apply under the Generalized System of Preferences (GSP) for eligible developing countries, often requiring a GSP Form A. The specific documentation and origin requirements vary by agreement and importing country.

FAQ
What are the primary classification criteria for HS code 740322 (Copper-tin base alloys, bronze)?
HS code 740322 specifically covers unwrought or partly wrought copper-tin base alloys, commonly known as bronze. The key classification criterion is the alloy composition, which must primarily consist of copper and tin. While other elements may be present, tin is the principal alloying element after copper. The physical form (unwrought, bars, rods, profiles, wire, plates, sheets, strip, foil, tubes, pipes, or hollow profiles) also determines the specific subheading within Chapter 74, but 740322 itself refers to the material type. Refer to the Explanatory Notes of the Harmonized System for detailed compositional thresholds.
What are the typical import duty rates for HS code 740322, and how do preferential rates apply?
The Most Favored Nation (MFN) duty rate for HS code 740322 is typically 1.5% ad valorem in the United States. However, preferential duty rates significantly reduce or eliminate this. For instance, under various Free Trade Agreements (FTAs) such as those with Australia (AU), South Korea (KR), or Singapore (SG), the duty rate can be Free (0.00%). It is crucial to consult the specific tariff schedule of the importing country and the relevant trade agreement to confirm the applicable preferential rate based on the country of origin and proof of eligibility (e.g., Certificate of Origin).
How is the import duty for HS code 740322 calculated, and can you provide an example?
Import duty for HS code 740322 is generally calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For example, if the MFN duty rate is 1.5% and you import bronze bars valued at $10,000 USD, the duty would be calculated as: $10,000 (Value) × 1.5% (Duty Rate) = $150 USD. If a specific duty or a combination duty applies, the calculation would differ. Always verify the applicable duty basis (ad valorem, specific, or compound) with the importing country's customs authority.
What documentation is typically required when importing goods classified under HS code 740322?
Standard import documentation for HS code 740322 includes a commercial invoice, packing list, and bill of lading or air waybill. If claiming preferential duty rates under a Free Trade Agreement, a Certificate of Origin or other acceptable proof of origin is mandatory. Depending on the importing country and the specific nature of the bronze alloy (e.g., if it contains controlled substances or is for specific industrial use), additional certifications regarding composition, quality, or compliance with environmental regulations might be requested by customs authorities. Always consult the importing country's customs regulations for a comprehensive list.
Which major trade agreements offer preferential duty treatment for HS code 740322, and what are the general conditions?
Several trade agreements provide preferential duty treatment for goods classified under HS code 740322. Examples include agreements with countries like Australia (AU), South Korea (KR), and Singapore (SG), often resulting in a Free (0.00%) duty rate. Generally, to qualify for these preferential rates, the bronze alloy must originate from the partner country according to the rules of origin stipulated in the specific trade agreement. This typically requires the goods to be wholly obtained in the partner country or to have undergone substantial transformation there, and proof of origin (like a Certificate of Origin) must be provided to customs authorities at the time of import.
