SITCSection 7
U.S. imports of parts for taps, cocks, valves & similar appliances (SITC 74790) totaled $316.4M in April 2026, traded with 70 countries.
Importers of Parts for Taps, Cocks, Valves & Similar Appliances paid $50.9M in duties in April 2026 — an effective duty rate of 20% on $258.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataReplacement and OEM parts — including valve bodies, bonnets, seats, discs, stems, and actuator components — for pipeline valves, boiler fittings, and tank appliances are traded under SITC 74790, separate from the complete valve assemblies they support. The parts heading is commercially significant for MRO (maintenance, repair, and operations) supply chains in refining, power generation, and water treatment, where sourcing individual components can be more cost-effective than replacing entire valve assemblies. Classification as a 'part' rather than a complete article requires that the item be identifiable as solely or principally used with a specific valve type, a distinction CBP scrutinizes closely.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP generally applies the 'solely or principally used' test: the item must be dedicated to use with a specific valve or class of valves and not have independent commercial utility as a standalone product. Items like valve seats, stems, and bonnets typically qualify; generic fasteners or seals that serve multiple product categories generally do not.
Not necessarily. Antidumping and countervailing duty orders, as well as Section 301 tariff lists, specify covered articles by HTS subheading. Parts subheadings may be covered under different — or no — orders compared to the complete valve subheadings. Importers should check the specific HTS code for parts against current CBP and USTR guidance rather than assuming the same treatment applies.
