This heading covers all natural clayey substances (other than kaolin and other kaolinic clays of heading 25.07) consisting of earths or rocks of sedimentary origin with a basis of aluminium silicates. The characteristic properties of these products are plasticity, the faculty of hardening when fired and resistance to heat. Because of these properties clays are used as raw materials in the ceramic industry (bricks, building tiles, porcelain, china, earthenware, refractory bricks and other refractory goods, etc.); common clay is also used for soil improvement.

These products remain in this heading even if they have been heated to remove some or most of the associated water (to produce absorbent clay) or when fully calcined.

In addition to common clays, the following special products also fall in the heading :

(1) Bentonite, a clay derived from volcanic ash; largely used as an ingredient of moulding sand, as a filtering and decolouring agent in oil refining and for degreasing of textiles.

(2) Fuller’s earth, a natural earthy material with high absorptive power, composed chiefly of attapulgite. It is used for decolourising oils, for degreasing textiles, etc.

(3) Andalusite, kyanite (or disthene) and sillimanite, natural anhydrous aluminium silicates used as refractories.

(4) Mullite, obtained by heat treatment of sillimanite, kyanite or andalusite or by fusing a mixture of silica or clay and aluminium oxide in an electric furnace; used in the preparation of refractory products with great resistance to heat.

(5) Chamotte earth, also called “fire‑clay grog”, obtained either by crushing fire‑clay bricks or by crushing a calcined mixture of clay with other refractory materials.

(6) Dinas earth, a refractory material which consists of quartzose earth containing clay or may be obtained by mixing clay with ground quartz or quartz sand.

This heading does not include :

(a) Clays which are earth colours within the meaning of heading 25.30.

(b) Activated clay (heading 38.02).

(d) Expanded clays (used in lightweight concrete aggregates or for heat insulation) even if obtained solely by calcining natural clays (heading 68.06).

Subheading Explanatory Notes.

Subheading 2508.10

Subheading 2508.10 includes sodium bentonites (swelling bentonites) and calcium bentonites (non‑swelling bentonites).

Subheading 2508.30

Subheading 2508.30 does not cover clays composed mainly of kaolin, some of which are “fire‑clays”. Such clays are to be classified in heading 25.07.

FAQs

What is HS code 2508?

HS code 2508 includes Salt; sulphur; earths and stone; plastering materials, lime and cement - Other clays (not including expanded clays of heading 68.06), andalusite, kyanite and sillimanite, whether or not calcined; mullite; chamotte or dinas earths..

How many sub-headings are there in HS code 2508?

There are 6 sub-heading(s) in HS code 2508.

What is an HS Code and Why Does it Hold For Cross-Border Trade?

HS code is a standardized six-digit numerical classification system developed by the World Customs Organization (WCO) and acts as a universal language for simplifying the process of identifying and classifying traded products. They ensure consistent customs clearance, enable accurate duty calculation, and help identify relevant trade regulations. This simplifies the process for businesses, saving time, reducing risk, and promoting informed decision-making.

What are Controls and Why should Businesses Focus on Them?

In global trade, controls refer to a set of regulations and policies implemented by governments to manage the import and export of goods and services. These controls can take various forms, including tariffs, quotas, embargoes, export controls, and licensing requirements. Companies should prioritize understanding and adhering to them for compliance, reduced risk of legal issues, mitigating reputational damage, staying competitive, and building trust with governments.

What are Tariffs in Global Trade and Why should Businesses Focus on Them?

In global trade, tariffs are a type of tax levied by a government on imported goods. They act as a financial barrier to entry, increasing the overall cost of the imported product for domestic consumers and businesses. By understanding how tariffs work and their potential impact, companies can make informed decisions about pricing, sourcing, and market expansion, ultimately ensuring their competitiveness in the global marketplace.

What are FTAs in Global Trade and Why should Businesses Focus on Them?

In global trade, Free Trade Agreements (FTAs) are legally binding agreements between two or more countries aimed at reducing or eliminating barriers to trade between them. By understanding the terms of relevant FTAs and strategically incorporating them into their business plans, companies can enjoy reduced costs, expanded market access, and a more competitive edge in international trade.
