HS 901210 Microscopes other than optical microscopes; diffraction apparatus
Quick Answer: Microscopes other than optical microscopes, and diffraction apparatus, imported under HS 901210 enter the UK at 0.00%, the EU at 0.00%, and the US at Free (MFN) or 40% (other rates may apply). This classification covers instruments that magnify or analyze specimens using methods other than visible light, such as electron microscopes or X-ray diffraction equipment. Importers should be aware of potential variations in duty rates and specific import requirements across jurisdictions. CustomTariffs aggregates this data, highlighting the importance of verifying the most current rates and any applicable trade agreements for accurate customs declarations.

How to Classify This HS Code?
What products does HS 901210 cover?
This subheading covers microscopes that do not operate by optical means, such as electron microscopes (transmission and scanning) and scanning probe microscopes (atomic force and scanning tunneling). It also includes diffraction apparatus, which are instruments used to study the diffraction patterns of waves or particles, as detailed in the World Customs Organization's Harmonized System Explanatory Notes and reflected in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database.
What falls outside HS 901210?
The following products are excluded from HS 901210: optical microscopes (classified under HS 9011), which use visible light for magnification. Also excluded are measuring or checking instruments, machines, and tools not specified or included elsewhere in Chapter 90, such as profilometers or surface roughness testers that do not function as diffraction apparatus, and simple magnifying lenses or hand-held magnifiers (typically classified under HS 9013).
What are common classification mistakes for HS 901210?
A common error is misclassifying optical microscopes under this subheading, failing to adhere to General Rule of Interpretation (GRI) 3(a) which prioritizes the most specific heading. Another mistake involves classifying specialized scientific instruments that may incorporate diffraction principles but are primarily designed for other functions, such as certain types of spectrometers, under HS 901210 instead of their more specific headings within Chapter 90.
How should importers classify products under HS 901210?
The correct procedure for classifying products under HS 901210 involves a thorough examination of the instrument's operating principle, referencing the World Customs Organization's Explanatory Notes and the specific definitions within the importing country's tariff schedule, such as the EU TARIC or the UK Trade Tariff. Importers and customs brokers must confirm that the microscope does not use optical means and that any diffraction apparatus is not more specifically classified elsewhere, ensuring compliance with all relevant legal texts.
How is the duty calculated for products under HS 901210?
A Scanning Electron Microscope (SEM) with a declared customs value of $50,000 USD would attract a US duty of $1,750.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.5% ad valorem, as published in the USITC Harmonized Tariff Schedule (HTS) for HS code 901210. The calculation is $50,000 × 0.035 = $1,750.00.
Which trade agreements reduce duties for HS 901210?
Several free trade agreements may reduce the applicable duty rate for HS 901210, including the United States-Mexico-Canada Agreement (USMCA), which can result in a 0% duty rate for qualifying goods originating from Canada or Mexico, requiring a self-certified origin statement. Additionally, the Generalized System of Preferences (GSP) may offer duty-free entry for eligible products from designated developing countries, typically requiring a GSP Form A. The EU and UK also have various preferential agreements that could lead to reduced or zero duties, often necessitating an EUR.1 movement certificate.

FAQ
What are the typical import duty rates for HS code 901210, covering microscopes other than optical and diffraction apparatus?
Import duty rates for HS code 901210 can vary significantly by country. For example, under the US Harmonized Tariff Schedule (HTS), the general Most Favored Nation (MFN) duty rate is Free. However, preferential rates under trade agreements may apply. In the European Union, the TARIC system indicates a 0.00% duty rate for this classification. It is crucial to consult the specific tariff schedule of the importing country for the most accurate and up-to-date rates, as well as any applicable trade agreements.
How is the duty calculated for HS code 901210 if a duty rate is applicable?
The calculation of duty for HS code 901210 depends on whether the duty is ad valorem (based on value) or specific (based on quantity), or a combination. For instance, if a hypothetical ad valorem duty rate of 4.00% were applied to an import of goods classified under 901210 with a declared customs value of $10,000, the duty would be calculated as: 4.00% of $10,000 = $400.00. Importers and brokers must verify the exact duty calculation method and rate from the destination country's customs authority.
What are the key classification criteria to ensure goods are correctly classified under HS code 901210?
HS code 901210 covers 'Microscopes other than optical microscopes; diffraction apparatus'. This means the primary classification criterion is that the microscope must not operate using visible light (optical). Examples include electron microscopes (scanning electron microscopes - SEM, transmission electron microscopes - TEM) and scanning probe microscopes (atomic force microscopes - AFM, scanning tunneling microscopes - STM). Diffraction apparatus, such as X-ray diffractometers, also falls under this code. Goods that are optical microscopes (e.g., compound light microscopes, stereo microscopes) would be classified elsewhere, typically under HS code 9011. Verification often requires technical specifications and product literature.
What documentation is typically required for importing goods under HS code 901210?
Standard import documentation for HS code 901210 generally includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the specific nature of the equipment, additional documentation may be required. This could include a certificate of origin to claim preferential duty rates under trade agreements, import licenses, or specific declarations regarding the technology or intended use of the scientific apparatus. It is advisable for importers and customs brokers to consult the importing country's customs authority or a trade compliance specialist for a comprehensive list.
Which common trade agreements might offer preferential duty rates for HS code 901210?
Preferential duty rates for HS code 901210 can be accessed through various trade agreements. For imports into the United States, the USMCA (United States-Mexico-Canada Agreement) might offer duty-free treatment if the goods originate in Canada or Mexico and meet the rules of origin. Similarly, the EU has numerous Free Trade Agreements (FTAs) with countries worldwide that could reduce or eliminate duties on goods classified under 901210. The UK also has a network of FTAs post-Brexit. To determine eligibility, importers and brokers must consult the specific text of the relevant trade agreement and ensure the goods meet all stipulated rules of origin criteria.
