Last updated: August 2026 dataSwivel seats with variable height adjustment and a wooden frame — a category that includes height-adjustable wooden office and drafting chairs — are classified under a single tariff line (9401310000) distinguished from metal-frame or plastic-frame equivalents by their primary structural material. Canada and Vietnam are the leading US suppliers, with China also a notable source. Wooden-frame swivel seating from China may be subject to Section 301 tariffs, making origin documentation and substantial transformation analysis particularly important for importers sourcing components from multiple countries.

CBP classifies a swivel seat as wooden when wood constitutes the essential character of the frame structure. A seat with a steel or aluminum base mechanism but wooden back and seat panels may not qualify — the frame that provides structural support is the determining element. Seats where the primary load-bearing structure is metal with decorative wood accents are typically classified under the NESOI swivel seat heading (9401.39).
The variable height adjustment feature is a mandatory classification criterion for 9401.31. A wooden swivel chair without a height-adjustment mechanism does not qualify under this subheading and would instead be classified elsewhere in heading 9401 based on its construction and use — likely under 9401.69 (other wooden seats) if it lacks both swivel and height-adjustment functions. Importers should verify that the adjustment mechanism is functional and present in the imported article.
