By Census's concordance, most of its statistical lines are made by Plastics Material and Resin Manufacturing (325211). Those are the NAICS industries a US producer of these goods would report under.
The heading text decides whether a product belongs here at all (General Rule of Interpretation 1); the subheadings and lines below it only apply once that is settled. Section and chapter notes can override the heading wording, so read them for borderline goods.
