Classification as plastic furniture generally requires that plastic constitute the essential character of the article—typically meaning it forms the primary structural component by weight, value, or function. A metal-framed chair with a plastic seat may be classified as metal furniture rather than plastic furniture. When the material split is close, importers should seek a CBP binding ruling to confirm the correct heading.

Beyond standard HTS classification and Section 301 tariff checks (which apply to Chinese-origin goods), importers should verify country-of-origin substantiation if production has shifted from China to Vietnam or other countries. CBP has scrutinized transshipment in the furniture sector broadly. Additionally, California Proposition 65 and CPSC flammability or safety standards may apply depending on the article's end use.
