U.S. imports of circular saw blades with non-steel working part, and parts, of base metal (HS 820239) totaled $16.7M in April 2026, traded with 34 countries.
Importers of Circular Saw Blades with Non-Steel Working Part, and Parts, of Base Metal paid $1.7M in duties in April 2026 — an effective duty rate of 11% on $14.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataCarbide-tipped and diamond-segment circular saw blades dominate commercial trade under this heading, which covers any base-metal circular saw blade whose working part is a material other than steel. The US schedule subdivides the heading into diamond-working-part blades (8202390010), diamond blade cores (8202390040), and other non-steel working-part blades (8202390070), making the abrasive or cutting-tip material the pivotal classification variable. Thailand leads US imports, with Vietnam and South Korea also significant sources, reflecting the concentration of precision cutting-tool manufacturing in Asia. Diamond saw blades used in concrete, masonry, and stone cutting are a high-value segment where blade segment bond hardness, diamond grit size, and core steel specification are the technical parameters most scrutinized by professional buyers.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes — the US tariff schedule specifically enumerates diamond sawblade cores at 8202390040, separate from finished blades with diamond working parts at 8202390010. Importers of unfinished cores for domestic segment attachment should use 8202390040 and ensure invoices describe the article as a core rather than a complete blade.
CBP may scrutinize low declared values for diamond blades given the wide price range between commodity and professional-grade products. Importers should retain manufacturer spec sheets showing diamond concentration, segment bond type, and blade diameter, along with purchase orders and price lists, to substantiate transaction value and avoid first-sale or assist adjustments.
