HS 842330 Constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales
Quick Answer: Constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales, imported under HS 842330 enter the UK duty-free, the EU at 0.00% or 1.70% ad valorem, and the US at Free or 45% ad valorem. This classification specifically covers automated weighing and dispensing machinery, distinct from simple weighing instruments. Importers should verify the specific tariff line within each jurisdiction to determine the exact duty rate applicable to their product, as variations exist. According to CustomTariffs data, understanding these nuances is crucial for accurate customs declarations and cost management in international trade.

How to Classify This HS Code?
What products does HS 842330 cover?
This subheading covers automatic weighing machinery designed to discharge a predetermined weight of material, often referred to as "constant weight feeders" or "bagging scales." According to the World Customs Organization (WCO) Harmonized System Explanatory Notes and definitions found in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC, this category includes machines that continuously weigh and dispense materials into bags, containers, or directly onto conveyors, ensuring a consistent weight output for each unit. Hopper scales that automatically discharge a set weight also fall within this classification.
What falls outside HS 842330?
The following products are excluded from HS 842330: general-purpose weighing machinery not specifically designed for automatic discharge of a predetermined weight, such as laboratory balances (HS 8423.20) or platform scales for manual operation (HS 8423.82). Also excluded are machines that measure volume rather than weight, or those that simply count items. For instance, automated packaging machines that seal bags but do not perform the weighing function are classified elsewhere, typically in Chapter 84.
What are common classification mistakes for HS 842330?
A common error is misclassifying machines that perform multiple functions. If a machine weighs material and then also performs a secondary operation like sealing or palletizing, and the weighing function is not the primary or defining characteristic for automatic discharge of a predetermined weight, it may be classified under a different heading. According to General Rule of Interpretation (GRI) 3(b), goods consisting of different materials or components which cannot be classified by reference to the principle in GRI 3(a) are to be classified as if they consisted of the material or component which gives them their essential character. This principle can lead to misclassification if the essential character is not the automatic weighing and discharging aspect.
How should importers classify products under HS 842330?
The correct procedure for classifying products under HS 842330 involves a thorough examination of the machine's primary function. Importers and customs brokers must verify that the equipment is designed for the automatic weighing and discharging of a predetermined weight of material. Reviewing the manufacturer's specifications, operational manuals, and product brochures is crucial. Cross-referencing these details with the official WCO Explanatory Notes and the specific tariff schedule of the importing country, such as the USITC HTS or EU TARIC, will confirm the correct classification and any associated subheadings.
How is the duty calculated for products under HS 842330?
A bulk bagging scale designed for filling 25 kg bags of fertilizer, declared at a customs value of $15,000 USD, would attract a US duty of $1,500.00. This is calculated using the Most Favored Nation (MFN) rate of 10% ad valorem, applied to the declared value ($15,000 USD × 10% = $1,500.00). This calculation is based on the duty rate published in the USITC Harmonized Tariff Schedule for subheading 8423.30.0000.
Which trade agreements reduce duties for HS 842330?
Several free trade agreements may reduce the applicable duty rate for HS 842330, including the United States-Mexico-Canada Agreement (USMCA) and the General System of Preferences (GSP) for qualifying developing countries. Under USMCA, originating goods from Canada or Mexico can enter the US duty-free. For GSP beneficiaries, a preferential rate of Free may apply, contingent on meeting origin requirements and presenting a GSP Form A. Documentation required to claim preference typically includes a self-certified origin statement for USMCA or the GSP Form A for GSP-eligible countries, demonstrating that the goods originate from a beneficiary country.

FAQ
What are the typical duty rates for HS code 842330 (constant weight scales and hopper scales)?
Duty rates for HS code 842330 can vary significantly by country. For example, under the United States Harmonized Tariff Schedule (USHTS), the Most Favored Nation (MFN) duty rate is 0.00%. In the European Union, under the TARIC system, the rate is also 0.00%. The UK Trade Tariff lists a duty rate of 0.00% for goods originating from countries with a Free Trade Agreement. However, standard rates can differ; for instance, some countries may apply rates up to 1.70% or higher for goods not covered by preferential agreements. Always consult the specific tariff schedule of the importing country for the definitive rate applicable to your goods.
What specific features define a scale for classification under HS 842330?
HS code 842330 covers 'Constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales.' Key classification criteria include the scale's primary function: to automatically weigh a constant flow of material (constant weight scales) or to dispense a specific, pre-set weight of material into packaging (hopper scales). These are typically industrial machines used in manufacturing, agriculture, or bulk handling. Scales that simply weigh items for retail sale or general weighing purposes would likely fall under different HS codes within Chapter 8423.
How is the duty calculated for HS code 842330 if a duty rate applies?
The calculation depends on whether the duty is ad valorem (a percentage of the value) or specific (a fixed amount per unit). If an ad valorem rate applies, the duty is calculated as: (Customs Value of Goods) × (Ad Valorem Duty Rate). For example, if a country applies a 1.70% ad valorem duty rate to a shipment of hopper scales valued at $10,000 USD, the duty would be $10,000 USD × 0.0170 = $170 USD. If a specific duty rate applies (e.g., $5 per unit), the calculation would be: (Number of Units) × (Specific Duty Rate per Unit). Always verify the duty calculation basis with the importing country's customs authority.
What documentation is typically required for importing scales classified under HS 842330?
Standard import documentation for HS code 842330 generally 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 if preferential duty rates are claimed under a trade agreement. Depending on the country of import and the specific nature of the scale (e.g., if it's considered measuring equipment requiring calibration), additional certifications or declarations related to accuracy, safety standards, or metrology might be necessary. Importers should consult the customs regulations of the destination country.
Do trade agreements like USMCA or EU Free Trade Agreements affect the duty rates for HS 842330?
Yes, trade agreements can significantly impact duty rates for HS code 842330. For instance, goods originating from countries that are signatories to the United States-Mexico-Canada Agreement (USMCA) may qualify for duty-free entry into the United States, provided they meet the rules of origin. Similarly, many Free Trade Agreements (FTAs) between the European Union and third countries, or the UK's FTAs, offer reduced or eliminated tariffs on goods classified under 842330 if the origin requirements are satisfied. Importers must obtain a valid Certificate of Origin and ensure compliance with all stipulated rules of origin to benefit from these preferential rates.
