U.S. imports of Other Metal Valves & Pipe Fittings (NAICS 332919) totaled $67.8M in August 2026, imported from 53 countries.
Importers of Other Metal Valves & Pipe Fittings paid $17.5M in duties in August 2026, an average duty rate of 25.84% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Other Metal Valves & Pipe Fittings imports of $67.8M in August 2026 ran 11% above the year-to-date monthly average of $61.2M.
Last updated: August 2026 dataResidual metal valves and pipe fittings not captured by the more specific NAICS categories — including needle valves, solenoid valves, and specialty couplings — populate this catch-all grouping, which serves a wide range of end-use sectors from HVAC to semiconductor fabrication. The breadth of products means HTS classification requires careful attention to actuation method, body material, and nominal pipe size, as these factors determine both the applicable duty rate and any trade-remedy exposure. Importers dealing in specialty alloy fittings for high-purity or high-pressure applications should be prepared to provide material test reports and mill certifications at entry.

NAICS 332912 covers fluid power valves and hose fittings specifically designed for hydraulic or pneumatic circuits, while 332996 covers fabricated pipe and pipe fittings made by forming processes. NAICS 332919 captures the remainder — valves and fittings that don't fit those narrower definitions, such as solenoid valves, needle valves, and general-purpose couplings. The HTS classification, however, is determined independently of NAICS and turns on the product's construction and function.
Material test reports (MTRs) are not a CBP customs requirement per se, but they are routinely demanded by end-users in oil and gas, power, and chemical sectors to verify compliance with ASTM, ASME, or MSS standards. Importers should obtain MTRs from the manufacturer before shipment, as retroactive documentation is difficult to secure and can delay project delivery.
