Last updated: August 2026 dataPVC profile shapes — including exterior siding (3916200010), window, door, decking, and railing profiles (3916200020), and other rods and sticks (3916200091) — are widely used in residential and commercial construction. Canada leads US imports, but China, Mexico, Taiwan, and Vietnam are all significant sources, and Chinese-origin PVC profiles are subject to Section 301 tariffs, making origin and tariff engineering a recurring concern for construction product importers. The heading's subdivision into specific building product categories (siding, window/door/decking profiles) reflects the commercial importance of these shapes in the US construction market and allows for more targeted duty treatment.

The specific line 3916200020 covers profiles designed and used as window frames, door frames, decking, or railing components — products with a defined architectural end use. General PVC rods, sticks, and profiles that do not fit those specific construction applications fall under the residual line 3916200091. Importers should document the intended end use and product specifications, as CBP may request evidence that a profile is specifically designed for window or door frame applications to support the specific line.
PVC profile shapes of Chinese origin are subject to Section 301 tariffs. The applicable rate and any available product exclusions depend on the specific 10-digit HTS line and the current state of the Section 301 lists. Importers should verify the current duty treatment with a licensed customs broker before shipment, as exclusions and list modifications are updated periodically by USTR.
