HS 901730 Micrometers, callipers and gauges
Quick Answer: Micrometers, callipers, and gauges imported under HS 901730 enter the UK at 2.00%, the EU at 2.70%, and the US with rates varying from 3.9% to Free, and a 45% rate for certain origins. This HS code encompasses precision measuring instruments used for determining dimensions, such as vernier callipers for measuring external and internal distances, micrometers for highly accurate linear measurements, and various other gauges for checking tolerances. Importers should be aware of the specific origin-based duty rates in the US, as detailed on USITC.gov. Exporters should verify the correct classification and applicable duties in their destination markets, as CustomTariffs aggregates this information.

How to Classify This HS Code?
What products does HS 901730 cover?
This subheading covers micrometers, callipers, and gauges, as defined by the World Customs Organization (WCO) Harmonized System (HS) Nomenclature. These are precision measuring instruments used for determining dimensions, distances, or angles with high accuracy. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database provide further detail, generally including vernier, dial, and digital versions of these tools, essential for mechanical engineering, manufacturing, and quality control applications.
What falls outside HS 901730?
The following products are excluded from HS 901730: general measuring tapes (classified under 9017.80), spirit levels (classified under 9031.80), and simple rulers or measuring sticks not possessing the precision of micrometers, callipers, or gauges. Also excluded are electronic measuring devices that do not specifically function as micrometers, callipers, or gauges, such as digital thermometers or pressure gauges, which fall under different HS codes based on their primary function.
What are common classification mistakes for HS 901730?
A common error is misclassifying digital measuring tools that incorporate features beyond simple dimension measurement, such as data logging or connectivity, which might warrant classification under more specific headings within Chapter 90. Additionally, confusing precision measuring instruments with general-purpose tools like simple rulers or tape measures can lead to incorrect classification, failing to adhere to General Rule of Interpretation (GRI) 1, which prioritizes the heading and section notes for classification.
How should importers classify products under HS 901730?
The correct procedure for classifying products under HS 901730 involves a thorough examination of the product's design, function, and precision. Importers and customs brokers should consult the official HS Explanatory Notes and the specific tariff schedules of the importing country, such as the USITC HTS or the EU TARIC. Verification of the instrument's primary purpose as a micrometer, calliper, or gauge is crucial, ensuring it meets the precision standards implied by the subheading.
How is the duty calculated for products under HS 901730?
A digital caliper weighing 0.5 kg and declared at a customs value of $100 USD would attract a US duty of $3.50. This is calculated using the Most Favored Nation (MFN) rate of 3.5% ad valorem, applied to the declared customs value ($100 USD × 0.035 = $3.50). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 9017.30.2000.
Which trade agreements reduce duties for HS 901730?
Several free trade agreements may reduce the applicable duty rate for HS 901730, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying originating goods from Canada and Mexico. For goods originating from the United Kingdom, a preferential rate of Free may apply under the UK-US Free Trade Agreement (if enacted and applicable). Documentation required typically includes a self-certified origin statement for USMCA and potentially a EUR.1 movement certificate for other agreements, depending on the specific jurisdiction and product origin.

FAQ
What are the typical import duty rates for HS code 901730 (Micrometers, callipers and gauges) into the United States?
The Most Favored Nation (MFN) duty rate for HS code 901730 into the United States is typically 2.00% ad valorem. However, preferential duty rates are available for goods originating from countries with which the U.S. has a Free Trade Agreement (FTA). For example, goods from Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), and Singapore (SG) may be eligible for duty-free entry (Free). Importers must provide proof of origin to claim these preferential rates. Always consult the latest Harmonized Tariff Schedule of the United States (HTSUS) published by the USITC for the most current and specific rates.
How is the import duty for HS code 901730 calculated, and can you provide an example?
The import duty for HS code 901730 is generally calculated on an ad valorem basis, meaning a percentage of the declared value of the goods. For instance, if the MFN duty rate is 2.00% and you import micrometers valued at $10,000 USD, the duty would be calculated as: $10,000 (value) × 0.02 (duty rate) = $200 USD. If a specific duty rate is applicable (e.g., per unit), it would be applied to the quantity imported. It is crucial to use the correct dutiable value, which typically includes the cost of the goods, insurance, and freight to the port of entry.
What are the key classification criteria for goods under HS code 901730?
HS code 901730 covers micrometers, callipers, and gauges designed for linear or angular measurement. The primary classification criteria revolve around the instrument's function and precision. Micrometers are used for highly precise measurements of small distances. Callipers are used to measure the distance between two opposite sides of an object. Gauges are instruments used to measure or compare a dimension or property of a workpiece against a standard. Instruments that do not meet the precision or specific measuring function of these items may fall under different HS codes within Chapter 90.
What documentation is typically required for importing goods classified under HS code 901730?
When importing goods under HS code 901730, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of origin and destination, a certificate of origin may be necessary to claim preferential duty rates. For precision measuring instruments, manufacturers' specifications or technical data sheets might be requested by customs authorities to verify the classification and ensure compliance with any specific standards or regulations. Importers should also be prepared for potential inspections by customs.
Are there specific trade agreements that significantly impact the duty rates for HS code 901730?
Yes, several trade agreements can significantly impact duty rates for HS code 901730. For example, the United States has FTAs with countries like South Korea (US-Korea Free Trade Agreement), Australia (AUSFTA), and others that often provide for duty-free or reduced-duty entry for qualifying goods. The European Union's TARIC system also reflects preferential rates under agreements with various countries. Similarly, the UK Trade Tariff details preferential rates stemming from the UK's trade deals. To benefit from these agreements, importers must ensure the goods meet the rules of origin and possess the required proof of origin documentation.
