HS 848130 · Check (non-return) valves
Get the code right at quotation time, not at customs.
Misclassifying HS 848130 on the commercial invoice walks the cargo into the wrong duty rate, the wrong rebate column, and a customs hold that costs days of demurrage to clear. This page gives you the WCO heading, the product it most often covers, the China VAT export rebate rate, the US Section 301 status, the supplier provinces that ship it, and practitioner buying notes for first-time importers.
For an explanation of how the WCO Harmonized System is structured, what each digit means, and why misclassification is the most common landed-cost error first-time buyers make, see the HS code glossary entry.

Specify the pressure rating (PN, ANSI Class), end-connection (flanged, threaded, butt-weld, wafer), body material, and trim material on the PO; cross-substitution by trim grade at the factory is a recurring quality issue.
