HS Code 25.16 – Granite, porphyry, basalt, sandstone, other monumental and building stone, whether or not roughly trimmed, cut, by sawing etc, into blocks or slabs of a rectangular (including square) shape

HS code 2516 is a 4-digit heading in the Harmonized System that covers: Granite, porphyry, basalt, sandstone, other monumental and building stone, whether or not roughly trimmed, cut, by sawing etc, into blocks or slabs of a rectangular (including square) shape. Heading 2516 covers a broad category of monumental or building stones, specifically granite, porphyry, basalt, sandstone, and other similar stones. This classification applies to these stones whether they are roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape. This definition is critical, as it delineates the extent of processing allowed for classification under this heading, focusing on primary forms. Granite, an igneous rock, is highly prized for its hardness, durability, and a wide array of colors, making it a staple for countertops, flooring, and exterior cladding. Porphyry, another igneous rock, often features distinct large crystals in a finer-grained matrix, used for paving and decorative elements. Basalt, a dense volcanic rock, is commonly used for paving stones, aggregates, and building foundations. Sandstone, a sedimentary rock, is valued for its natural aesthetic, slip resistance, and workability, frequently used in facades, paving, and landscaping. The term 'other monumental or building stone' encompasses similar natural stones not specifically named but sharing these characteristics and processing levels. The scope of 2516 is limited to these natural stones in their initial block or slab forms. Further processing, such as polishing, chamfering, shaping into finished articles (e.g., finished countertops, paving sets, carved monuments), or combining with other materials, would typically lead to classification in Chapter 68. This heading is for the raw material, not the finished product. Accurate classification is paramount for trade compliance, affecting import duties, taxes, and adherence to specific building material standards. Historically, these stones have been fundamental to construction and monumental architecture across diverse cultures for millennia. This heading falls within Chapter 25 (Salt; Sulphur; Earths and Stone; Plastering Materials, Lime and Cement), which focuses on natural mineral products in their crude or minimally processed states, underscoring their status as fundamental raw materials.

Rough granite blocks, sawn granite slabs (rectangular), porphyry blocks, porphyry slabs (rectangular), basalt blocks, basalt slabs (rectangular), sandstone blocks, sandstone slabs (rectangular), monumental granite, building sandstone, black basalt blocks, red granite slabs, yellow sandstone blocks, grey porphyry slabs, roughly trimmed granite, saw-cut basalt, monumental stone slabs, building stone blocks, raw granite for countertops (pre-cut slabs), large sandstone slabs for paving, basalt for cobbles (rough cut), unpolished granite slabs, untrimmed sandstone blocks, square basalt slabs, granite quarry blocks, rough-cut porphyry, natural sandstone, rectangular granite stock.

A common misclassification involves confusing these stones with other natural monumental or building stones. For example, marble, travertine, and alabaster fall under 2515, not 2516, due to their different geological compositions and sometimes specific gravity criteria. Another frequent mistake is classifying finished articles made from these stones, such as polished granite countertops, precisely cut paving sets, or carved basalt statues, which typically belong to Chapter 68 (e.g., 6802). The key is the specific stone type and the processing level: 'roughly trimmed' or 'cut... into blocks or slabs of a rectangular (including square) shape' only, not further worked or finished.

In 2025, the top exporters of HS code 2516 in UN Comtrade data were India ($557M, 40% of world exports), Brazil ($181M) and Spain ($66M). World exports came to about $1.4B, 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 2516 in UN Comtrade data were China ($872M, 47% of world imports), the United Kingdom ($144M) and Italy ($137M). World imports came to about $1.9B, 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 2516 is a 4-digit heading under Chapter 25 of the Harmonized System. The first 2 digits (25) identify the chapter, and digits 3-4 (16) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
