HS 252910 Feldspar

Quick Answer: HS code 252910 covers feldspar, a common group of rock-forming minerals primarily used in the manufacture of glass, ceramics, and as a filler in paints and plastics. For importers and exporters, this classification generally benefits from favorable duty treatment across major jurisdictions. The United Kingdom and the European Union apply a 0.00% ad valorem duty rate. In the United States, feldspar is classified as "Free" of duty, with a specific rate of 49¢ per tonne previously applicable to certain forms but now effectively zero. This widespread duty-free status simplifies trade compliance, making feldspar a relatively straightforward commodity for international movement. Importers should still ensure accurate product descriptions and origin documentation.

How to Classify This HS Code?

What products does HS 252910 cover?

This subheading covers feldspar, whether or not crushed, ground, or powdered, as defined by the Harmonized System Nomenclature (HSN) under Heading 2529, which specifically addresses feldspar, leucite, nepheline, and nepheline syenite. Feldspar is a group of rock-forming tectosilicate minerals that make up as much as 60% of the Earth's crust, commonly used in glass and ceramic manufacturing. The USITC Harmonized Tariff Schedule (HTS) and EU TARIC both align with this WCO definition, encompassing all forms of feldspar provided it retains its essential character as the mineral, regardless of the degree of processing for transport or initial industrial use.

What falls outside HS 252910?

The following products are excluded from HS 252910: leucite, nepheline, and nepheline syenite, which are classified under HS 252920, even though they are related aluminosilicate minerals often found in similar geological contexts and used for comparable industrial purposes. Furthermore, feldspar that has been further processed beyond simple crushing or grinding, such as being mixed with other materials to form a prepared ceramic body or glaze, would be classified elsewhere, typically in Chapter 32 or 69, depending on its final form and composition. For instance, prepared glazes containing feldspar are excluded, as are finished ceramic articles.

What are common classification mistakes for HS 252910?

A common error is misclassifying feldspar that has undergone minimal processing, such as simple washing or screening, as a more advanced manufactured product, or conversely, classifying leucite or nepheline as feldspar. Importers sometimes overlook the specific distinction within Heading 2529, leading to incorrect use of HS 252910 instead of HS 252920 for the related minerals. Adherence to General Interpretative Rule (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes, is crucial here to ensure the correct mineral is identified and assigned to its specific subheading.

How should importers classify products under HS 252910?

The correct procedure for classifying products under HS 252910 involves first confirming the mineral's identity as feldspar through geological analysis or supplier documentation, ensuring it is not leucite, nepheline, or nepheline syenite. Importers and customs brokers should verify that the feldspar has not been processed beyond crushing, grinding, or powdering, as further manufacturing would lead to classification outside this subheading. Consulting the WCO Explanatory Notes for Heading 2529, along with the specific national tariff schedules like the USITC HTS or EU TARIC, will provide definitive guidance on scope and exclusions, ensuring accurate declaration and compliance with international trade regulations.

FAQ

What are the typical import duty rates for Feldspar (HS 2529.10) in major markets?

The import duty rates for Feldspar (HS 2529.10) are often very low or zero in many major trading blocs. For example, under the Harmonized Tariff Schedule of the United States (HTSUS), the Most Favored Nation (MFN) duty rate for 2529.10.00.00 is 0.00% ad valorem. Similarly, the EU TARIC database typically shows a 0.00% ad valorem duty rate for feldspar under this heading. In some specific markets or for certain forms, a nominal specific duty might apply, such as '49¢/t' (cents per tonne) as seen in historical or specific regional tariffs, though 'Free' or 0.00% ad valorem is prevalent for crude or simply crushed feldspar. Importers should always verify the exact duty rate applicable to their specific country of import and origin using the official tariff database (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff).

What are the key classification criteria for feldspar under HS 2529.10?

HS code 2529.10 specifically covers 'Feldspar'. The primary classification criterion is that the product must be feldspar, a group of rock-forming tectosilicate minerals. This heading typically includes feldspar in its crude, simply crushed, ground, or powdered forms. It generally excludes feldspar that has undergone further processing beyond simple preparation, such as calcining or specific chemical treatment, which might lead to classification under different headings, particularly Chapter 28 or 38 if it becomes a specific chemical compound or prepared mineral. The World Customs Organization (WCO) Explanatory Notes for Chapter 25 clarify that this chapter covers mineral products in their crude state or after having been subjected to certain basic preparatory processes, which aligns with the typical forms of feldspar found under 2529.10.

Are there any preferential duty rates available for feldspar under HS 2529.10 through common trade agreements?

Yes, preferential duty rates, often resulting in 'Free' entry, are commonly available for feldspar (HS 2529.10) under various trade agreements. For instance, imports into the United States from countries party to agreements like the USMCA (United States-Mexico-Canada Agreement), CAFTA-DR (Dominican Republic-Central America Free Trade Agreement), or various Free Trade Agreements (FTAs) with individual countries often qualify for a 0.00% preferential duty rate, provided the rules of origin are met. Similarly, within the EU, imports from GSP (Generalized System of Preferences) beneficiary countries or countries with EU FTAs may also benefit from reduced or zero duties. Importers must ensure they have the correct documentation, such as a Certificate of Origin, to claim these preferential tariffs and verify the specific agreement's rules of origin for feldspar.

What documentation is typically required for importing feldspar under HS 2529.10?

Standard import documentation is required for feldspar under HS 2529.10. This typically includes a commercial invoice, packing list, bill of lading or air waybill, and a customs declaration. To claim preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin (e.g., USMCA Certificate of Origin, EUR.1 movement certificate for EU trade agreements, or a GSP Form A) is essential. While feldspar is generally not subject to extensive regulatory controls, importers should verify if any specific environmental, health, or safety certifications are required by the importing country, especially if the material is intended for sensitive applications (e.g., food contact ceramics). It is always advisable to consult with a licensed customs broker or the relevant customs authority in the importing country for precise requirements.
