Plain-language overview
Use HS-6 902590 when importing or exporting hydrometers and similar floating instruments that are not specifically classified elsewhere. For instance, if you're shipping a set of hydrometers used for measuring the density of liquids, this code applies.
This code covers a variety of measuring instruments related to fluid properties, but it specifically excludes certain types of thermometers or barometers that have their own classifications. For example, HS-6 902511 is for specific types of thermometers, while HS-6 902580 includes other measuring instruments.
When dealing with instruments like barometers or hygrometers, ensure you’re using the correct code. If your product is a combination of these instruments, HS-6 902590 is the right choice. It allows for flexibility in classification for mixed-use instruments.
For accurate customs clearance, it’s crucial to differentiate between similar instruments. If you’re unsure whether your instrument fits HS-6 902590 or another subheading, consult with a customs broker for guidance.
