Pressure sensor Hs Code

Pressure sensor harmonized system code

Product Overview Pressure sensors classified under HS Code 902620 are precision electromechanical devices designed to measure and monitor pressure levels in gases or liquids. These sensors convert physical pressure into an electrical signal for accurate quantitative analysis. Typically constructed from corrosion-resistant materials such as stainless steel or specialized alloys, they exhibit high durability and stability across a broad range of operating conditions. Key physical specifications include measurement ranges spanning from vacuum levels (e.g., -1 bar) up to several hundred bars, with output signals standardized in millivolts, milliamperes, or digital protocols (4-20 mA, 0-10 V, or fieldbus interfaces). The classification under HS Code 902620 encompasses subcategories including piezoresistive, capacitive, piezoelectric, and strain gauge pressure sensors, each tailored for specific responsiveness and environmental resilience. These sensors find extensive application in food service and processing industries for pressure regulation, quality control, and safety monitoring in pneumatic and hydraulic systems. Their robust design and compliance with international metrology standards position them as essential components in global supply chains, offering reliable performance and facilitating regulatory adherence. HS Code Classification & Trade Specifications The HS Code 902620 is defined within Chapter 90 (Optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus), Heading 9026 (Instruments and apparatus for measuring or checking pressure), with Subheading 902620 specifying pressure measuring instruments specifically. Classification under this code is based on the device’s primary function to measure pressure, distinct from other measuring instruments by its operational principle and output type. For international trade, pressure sensors are commonly packaged in anti-static, moisture-resistant materials with shock-absorbent internal supports to preserve calibration integrity during transit. Shipping methods adhere to ISO 9001 quality management standards and often require compliance with RoHS and CE certifications for electronic components. Preservation involves controlled humidity and temperature to prevent sensor degradation. Documentation must reflect precise product specifications, including measurement range, accuracy (often ±0.1% FS), and response time, to ensure customs classification accuracy and facilitate expedited clearance processes under WTO trade agreements. The consistent use of this HS code across jurisdictions aids import/export businesses and customs brokers in maintaining compliance and streamlining international logistics.
