Last updated: April 2026 dataLarger synchronous belts in the 150–198 cm circumference range serve heavy-duty automotive timing systems, industrial servo drives, and large-format printing and packaging equipment where precise indexing over longer belt paths is required. Japan is the leading US supplier, followed by Thailand and Germany — a mix that reflects Japanese OEM dominance in automotive timing belts and the growth of Thai manufacturing as a regional hub for Japanese belt producers. Six 10-digit lines mirror the structure of the 60–150 cm heading, with splits by fiber type and width, so classification procedure is identical: confirm fiber composition and measure belt width.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Heading 401035 covers belts 'exceeding 60 cm but not exceeding 150 cm,' so a belt of exactly 150 cm falls within 401035, not 401036. Heading 401036 begins at circumferences exceeding 150 cm. Precise measurement and clear documentation of the measurement method are essential to avoid misclassification at the boundary.
Several major Japanese belt manufacturers operate production facilities in Thailand, supplying both the regional automotive OEM market and US aftermarket channels. Importers sourcing from Thailand should evaluate whether goods qualify for any applicable preferential tariff treatment and confirm that no trade-remedy orders apply at the time of entry.
