Last updated: April 2026 dataGlaziers' putty, grafting putty, resin cements, and related nonrefractory surfacing preparations for facades, walls, floors, ceilings, and similar surfaces split at the 10-digit level by binder chemistry: rubber-based formulations (3214901000) versus all others (3214905000). Germany leads US import supply, reflecting its strength in high-performance construction chemistry, with Mexico and Canada also significant sources. The rubber-based vs. non-rubber distinction is a common classification challenge, as silicone and polyurethane sealants may require careful analysis to determine whether they are more properly classified here or under Chapter 39 (plastics) or Chapter 40 (rubber). Importers should confirm the primary binder composition with suppliers before filing entry.

Silicone sealants can be contested between heading 3214 (surfacing preparations) and Chapter 39 (plastics). The key factor is whether the product is a finished preparation put up for retail or professional use as a surfacing/sealing compound — which favors 3214 — versus a primary silicone polymer form. Classification should be confirmed with a licensed customs broker using the product's technical data sheet and GRI rules.
The two 10-digit lines (3214901000 for rubber-based and 3214905000 for all others) may carry different duty rates. Importers should verify current rates in the Harmonized Tariff Schedule of the United States at the time of entry, as rates can be modified by trade actions or legislative changes.
