HS Code 84.23 – Weighing machines; excluding balances of a sensitivity of 5cg or better, including weight operated counting or checking machines and weights of all kinds

HS code 8423 is a 4-digit heading in the Harmonized System that covers: Weighing machines; excluding balances of a sensitivity of 5cg or better, including weight operated counting or checking machines and weights of all kinds. Heading 8423 encompasses weighing machines of all kinds, with the specific exclusion of balances of a sensitivity of 5 centigrams (0.05g) or better. This precise boundary is crucial for distinguishing industrial, commercial, and general-purpose weighing equipment from highly sensitive laboratory balances, which fall under Chapter 90. The heading also includes weight-operated counting or checking machines and weights of all kinds designed for use with weighing machines, making it a comprehensive category for all but the most precise weighing apparatus. Key sub-categories within 8423 include industrial platform scales, retail checkout scales, weighbridges for vehicles, crane scales, counting scales for parts, checkweighers for quality control, personal bathroom scales, postal scales, and calibration weights for testing scales. This classification is vital for trade compliance as it impacts applicable tariffs, import/export regulations, and eligibility for specific trade agreements. Misclassification can lead to customs delays, penalties, or incorrect duty payments. Historically, weighing has been fundamental to commerce and industry, evolving from simple beam balances to sophisticated electronic systems, all falling under this heading unless exceedingly sensitive. It sits within Section XVI, reinforcing its identity as essential mechanical (or electromechanical) apparatus for measurement in various practical applications, distinct from optical or precision instruments of Chapter 90.

Industrial platform scales, retail electronic scales with price computing, truck weighbridges, crane scales, laboratory scales (sensitivity less than 5cg), weight-operated counting machines, checkweighers for production lines, personal bathroom scales, kitchen scales, postal scales, veterinary scales, medical scales for patients, calibration weights for scales, load cells for weighing systems, bagging scales, bench scales, livestock scales, baggage scales, conveyor belt scales, hanging scales (industrial), force measurement scales (non-precision), precision balances (sensitivity > 5cg), spring scales (industrial), pallet jack scales, explosion-proof scales.

The most common misclassification for 8423 involves confusing it with high-precision laboratory balances of heading 9016. The critical distinction is the sensitivity threshold: 8423 covers machines with a sensitivity *less than* 5 centigrams (0.05g) or worse, while 9016 is for balances with a sensitivity of 5 centigrams or better. Another error can be classifying simple force gauges or dynamometers (9024) under 8423 if they measure force rather than mass. Traders must carefully check the technical specifications, particularly the sensitivity and primary function, to ensure correct classification.

In 2025, the top exporters of HS code 8423 in UN Comtrade data were China ($2.0B, 38% of world exports), Germany ($690M) and the United States ($376M). World exports came to about $5.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 8423 in UN Comtrade data were the United States ($874M, 18% of world imports), Germany ($310M) and the Netherlands ($253M). World imports came to about $4.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 8423 is a 4-digit heading under Chapter 84 of the Harmonized System. The first 2 digits (84) identify the chapter, and digits 3-4 (23) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
