HS Code 32.14 – Glaziers' putty, grafting putty, resin cements, caulking compounds and other mastics; painters' fillings; non-refractory surfacing preparations for facades, indoor walls, floors, ceilings or the like

HS code 3214 is a 4-digit heading in the Harmonized System that covers: Glaziers' putty, grafting putty, resin cements, caulking compounds and other mastics; painters' fillings; non-refractory surfacing preparations for facades, indoor walls, floors, ceilings or the like. HS Code 3214 covers a broad category of mastics, putties, fillers, and non-refractory surfacing preparations essential for construction, repair, and finishing work. This heading includes products like glaziers' putty, grafting putty, resin cements, caulking compounds, and various other mastics. It also encompasses painters' fillings and non-refractory surfacing preparations designed for facades, indoor walls, floors, ceilings, or similar surfaces. The defining characteristic is their function as filling, sealing, or surfacing agents, providing adhesion, flexibility, or a smooth finish, but not primarily as structural adhesives or high-temperature resistant materials. The 'non-refractory' distinction is critical, separating these from materials designed to withstand extreme heat. This classification is vital for trade compliance as it differentiates these construction and repair compounds from general adhesives (often in Chapter 35), certain plasters (like gypsum-based products in Chapter 25 or 68), or highly specialized industrial chemicals. Proper classification ensures correct duty rates and adherence to product-specific regulations, particularly in the construction sector. The heading's presence in Chapter 32 (Paints, varnishes, inks, putties) highlights its role alongside other surface treatment and finishing materials, bridging the gap between raw chemicals and finished construction elements.

Glaziers' putty, silicone caulking compounds, acrylic sealants, grafting putty for horticulture, epoxy resin cements for repair, polyurethane mastics, painters' spackling paste, wood fillers, joint compound for drywall, crack fillers for concrete, non-refractory facade repair compounds, floor leveling compounds, wall smoothing preparations, tile grout (non-cementitious type), expansion joint sealants, automotive body fillers, marine sealants, window glazing compounds, fire-rated caulks (non-refractory), roofing mastics, asphalt-based sealants, sealant tapes (if primarily mastic), gap fillers, adhesive mastics for construction, waterproof sealants.

A common misclassification involves confusing these products with adhesives falling under HS 3506 (Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg). While products in 3214 may have adhesive properties, their primary function is filling, sealing, or surfacing rather than solely bonding. Another error is classifying certain plasters or cements, which might be covered under 2520 (Gypsum; anhydrite; plasters (consisting of calcined gypsum or calcium sulphate) whether or not coloured, with or without small quantities of accelerators or retarders) or 2523 (Portland cement, aluminous cement, slag cement, supersulphate cement and similar hydraulic cements, whether or not coloured or in the form of clinkers), especially if they are primarily mineral-based and not 'preparations.'

In 2025, the top exporters of HS code 3214 in UN Comtrade data were Germany ($2.5B, 22% of world exports), the United States ($1.1B) and Belgium ($767M). World exports came to about $11.6B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 3214 in UN Comtrade data were Germany ($827M, 7.1% of world imports), China ($600M) and the United States ($559M). World imports came to about $11.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 3214 is a 4-digit heading under Chapter 32 of the Harmonized System. The first 2 digits (32) identify the chapter, and digits 3-4 (14) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
