Importers of Circular Knitting Machines with Cylinder Diameter Exceeding 165 mm paid $67K in duties in April 2026 — an effective duty rate of 10% on $656K in dutiable value, based on actual customs collections rather than the published tariff schedule. Circular Knitting Machines with Cylinder Diameter Exceeding 165 mm imports of $656K in April 2026 ran 138% above the year-to-date monthly average of $276K.
Last updated: April 2026 dataLarge-cylinder circular knitting machines produce wider tubular fabrics used in T-shirts, sportswear, underwear, and technical knits, making them central equipment for high-volume jersey and interlock fabric mills. Five 10-digit lines cover this heading, distinguishing hosiery machines (8447121000), open-top cylinder machines (8447129010), cylinder-and-dial machines (8447129020), and other non-hosiery types (8447129090). Japan leads US imports, followed by Germany and Italy — a supply profile that reflects the dominance of Japanese manufacturers in large-diameter, high-speed circular knitting technology. The cylinder-and-dial distinction (8447129020) is particularly important for importers of rib and interlock machines, which use both cylinder and dial needle beds.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A cylinder-and-dial machine uses two sets of needles — one in the rotating cylinder and one in a horizontal dial — to produce double-knit, rib, or interlock structures. An open-top cylinder machine uses only cylinder needles and produces single-jersey or similar single-bed fabrics. The presence or absence of a dial needle bed is the defining mechanical distinction between these two lines.
Japanese manufacturers of large-diameter circular knitters typically operate on order-to-manufacture lead times of several months, and ocean freight from Japan adds transit time. Buyers should factor in port congestion, currency fluctuation affecting yen-denominated pricing, and the availability of local technical service support when planning capital equipment procurement.
