HS 847983 Cold isostatic presses

Quick Answer: Cold isostatic presses imported under HS 847983 enter the UK at 0.00%, the EU at 1.70% ad valorem, and the US at 2.5% ad valorem, with preferential rates available for certain trading partners. This HS code specifically covers machines and mechanical appliances for the treatment of materials by a process involving a change of temperature, but not elsewhere specified or included, with a particular focus on cold isostatic presses. These are specialized machines that use a fluid medium to apply uniform pressure from all directions to a material, typically used in powder metallurgy and advanced ceramics manufacturing. Importers should be aware of potential specific import licenses or certifications required depending on the end-use and jurisdiction, as detailed in resources like the UK Trade Tariff and EU TARIC. According to CustomTariffs data, understanding these varied rates and potential trade considerations is crucial for accurate customs declarations and duty payments.

How to Classify This HS Code?

What products does HS 847983 cover?

This subheading covers cold isostatic presses, which are specialized machines designed to apply uniform pressure to a material enclosed in a flexible mold, typically using a fluid medium like water or gas. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes and definitions found in official tariff schedules such as the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC, these presses are used for compacting powders into dense, uniform shapes before sintering or other processing, commonly in industries like ceramics, metallurgy, and advanced materials manufacturing.

What falls outside HS 847983?

The following products are excluded from HS 847983: hot isostatic presses (HIP), which operate at elevated temperatures and pressures, and are classified under HS 841989; general-purpose hydraulic presses not specifically designed for cold isostatic pressing; and powder metallurgy equipment that performs other functions like sintering or compaction without the isostatic pressure application, such as uniaxial presses or vibratory feeders, which would be classified elsewhere within Chapter 84 based on their specific function.

What are common classification mistakes for HS 847983?

A common error is misclassifying hot isostatic presses as cold isostatic presses. This mistake often arises from overlooking the operational temperature. According to General Interpretative Rule 1 of the Harmonized System, classification is determined by the terms of the headings and any relative section or chapter notes. Hot isostatic presses, operating at significantly higher temperatures, fall under different headings, typically related to heat treatment machinery, while cold isostatic presses are specifically for room-temperature compaction.

How should importers classify products under HS 847983?

The correct procedure for classifying products under HS 847983 involves a thorough examination of the machine's operational specifications and intended use. Importers and customs brokers must verify that the equipment is designed for applying uniform pressure at ambient temperatures using a fluid medium to compact powders within a flexible mold. Consulting the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC, and reviewing the Explanatory Notes for Heading 8479 is crucial for accurate classification.

How is the duty calculated for products under HS 847983?

A cold isostatic press weighing 5,000 kg and declared at a customs value of $250,000 USD would attract a US duty of $12,500. This is calculated using the Most Favored Nation (MFN) duty rate of 5% ad valorem, as published in the USITC Harmonized Tariff Schedule for HS code 847983. The calculation is: 5% × $250,000 = $12,500. This rate applies to goods imported from countries not benefiting from preferential trade agreements.

Which trade agreements reduce duties for HS 847983?

Several free trade agreements may reduce the applicable duty rate for HS 847983. For instance, under the United States-Mexico-Canada Agreement (USMCA), qualifying cold isostatic presses originating from Canada or Mexico may enter the US duty-free. Similarly, goods originating from countries benefiting from the Generalized System of Preferences (GSP) may also receive reduced or zero duty rates. Documentation required to claim preference typically includes a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and importing jurisdiction.

FAQ

What are the typical import duty rates for HS code 847983 (Cold isostatic presses)?

The Most Favored Nation (MFN) duty rate for HS code 847983 is 1.70% ad valorem. However, preferential duty rates may apply under various trade agreements. For instance, imports from countries like Australia (AU), Canada (CA), Chile (CL), South Korea (KR), and Singapore (SG) may be eligible for duty-free entry (0.00%). It is crucial to verify the specific origin of the goods and consult the relevant trade agreement schedules for precise rates. Sources for verification include the USITC Harmonized Tariff Schedule, EU TARIC database, and UK Trade Tariff.

How is the import duty for a cold isostatic press calculated under HS 847983?

The duty for HS code 847983 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the imported goods. For example, if a cold isostatic press is valued at $100,000 USD and the MFN duty rate is 1.70%, the import duty would be $100,000 * 0.0170 = $1,700 USD. Always ensure the customs value is correctly determined according to international valuation rules (e.g., WTO Customs Valuation Agreement).

What are the key classification criteria for goods to be classified under HS 847983?

HS code 847983 specifically covers 'Cold isostatic presses'. The primary classification criterion is that the machine must be designed for applying uniform pressure to a product in all directions, typically using a fluid medium (like water or gas) at ambient temperature, to achieve densification or shaping of materials such as ceramics, metals, or composites. The machine must be a 'press' in its functional design. Machines that operate at elevated temperatures would generally fall under different headings. Consult the Explanatory Notes to the Harmonized System for detailed guidance.

Which trade agreements commonly offer preferential duty rates for cold isostatic presses (HS 847983)?

Several trade agreements can provide preferential duty rates, often resulting in duty-free (0.00%) entry for HS code 847983. Notable agreements include the United States-Mexico-Canada Agreement (USMCA), agreements with countries like Chile (CL), South Korea (KR), and Australia (AU), as well as agreements within the European Union (EU) and the UK's Global Tariff regime which offers preferential rates to partner countries. Importers must ensure they have a valid Certificate of Origin and meet all rules of origin requirements stipulated by the respective trade agreement.

What documentation is typically required when importing cold isostatic presses under HS 847983?

When importing cold isostatic presses under HS 847983, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of import and any claimed preferential treatment, a Certificate of Origin is crucial. For specialized machinery like isostatic presses, the manufacturer's technical specifications, operational manuals, and potentially a declaration confirming the machine's function (i.e., cold isostatic pressing) may be requested by customs authorities to verify correct classification. Compliance with any safety or electrical standards certifications may also be necessary.
