U.S. imports of constant-weight scales and hopper scales for predetermined-weight discharge (HS 842330) totaled $17.1M in May 2026, traded with 22 countries.
Importers of Constant-Weight Scales and Hopper Scales for Predetermined-Weight Discharge paid $1.2M in duties in May 2026 — an effective duty rate of 7.9% on $15.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Constant-Weight Scales and Hopper Scales for Predetermined-Weight Discharge imports of $17.1M in May 2026 ran 95% above the year-to-date monthly average of $8.8M.
Last updated: May 2026 dataHopper scales, net-weight fillers, and constant-weight batching systems used to discharge a preset quantity of bulk material into bags or containers are classified here — equipment central to grain milling, chemical blending, pet food, and fertilizer packaging operations. Japan leads US supply for this heading, followed by Germany and Denmark, reflecting the precision-engineering requirements of high-speed net-weight filling in food and agricultural applications. A single 10-digit line, 8423300000, covers the entire heading, so classification is unambiguous, but importers should verify whether the equipment's integrated control system affects valuation or requires separate software disclosure.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A hopper scale (8423.30) is designed to discharge a predetermined weight of material into a container — it controls the fill quantity. A checkweigher, by contrast, verifies the weight of already-filled packages passing on a conveyor and would typically classify under 8423.81 or 8423.82 depending on its maximum capacity. Misclassifying a net-weight filler as a checkweigher, or vice versa, can result in an incorrect duty rate and potential CBP penalties. The machine's operational sequence — whether it measures to fill or measures to verify — is the key classification criterion.
No antidumping, countervailing duty, or Section 232 measure currently targets hopper or constant-weight scales from Japan as a category. Importers should nonetheless run a current AD/CVD search against HTS 8423300000 at the time of entry, as trade-remedy orders can be initiated or modified. Japan is not a US free-trade-agreement partner, so standard MFN duty rates apply.
