Swivel Seats with Variable Height Adjustment (NESOI)

The household subdivision (9401390010) covers swivel seats with variable height adjustment intended for residential use, while 9401390030 captures commercial and institutional equivalents. The distinction matters because antidumping orders on certain seating products have historically defined scope by end-use category, and misclassification between these lines can affect AD/CVD liability. Importers should document the intended market channel and product specifications to support their line-level classification.

Yes. As manufacturers relocated assembly to Vietnam to avoid Section 301 tariffs, CBP increased scrutiny of whether Vietnamese-assembled chairs undergo sufficient substantial transformation to qualify as Vietnamese-origin goods. If key components such as seat mechanisms, gas cylinders, or bases are sourced from China and merely assembled in Vietnam without meaningful manufacturing operations, CBP may determine the country of origin remains China. Importers should conduct a thorough origin analysis and maintain detailed production records.
