HS 252922 Containing by weight more than 97 % of calcium fluoride
Quick Answer: HS code 252922 specifically covers fluorspar (calcium fluoride) with a high purity level, containing more than 97% by weight of calcium fluoride. This typically refers to acid-grade fluorspar, a critical raw material primarily used in the chemical industry for producing hydrofluofluorocarbon, aluminum fluoride, and synthetic cryolite, as well as in the steel and ceramics industries. For imports into the UK and EU, the Most Favoured Nation (MFN) duty rate is 0.00% ad valorem. In the United States, the MFN duty rate is $5.51 per tonne, though it may also be Free under specific trade agreements. Importers should verify eligibility for preferential tariffs. Given its industrial importance, trade considerations often include supply chain stability and compliance with environmental regulations related to mining and processing.

How to Classify This HS Code?
What products does HS 252922 cover?
This subheading covers natural calcium fluoride, commonly known as fluorspar or fluorite, specifically when its calcium fluoride content by weight exceeds 97%. This classification is derived directly from the Harmonized System (HS) Nomenclature, as interpreted by the World Customs Organization (WCO), and is consistently applied by major customs authorities such as the United States International Trade Commission (USITC) and the European Union's TARIC system. Products under this subheading are typically high-grade fluorspar, often used in metallurgical, chemical, and ceramic industries where high purity is essential. The "more than 97%" threshold is a critical determinant for inclusion here, distinguishing it from lower-grade varieties.
What falls outside HS 252922?
The following products are excluded from HS 252922: fluorspar containing 97% or less by weight of calcium fluoride, which would typically be classified under HS 252921. Additionally, chemically pure calcium fluoride (CaF2), which is a defined chemical compound obtained by synthesis, is excluded and falls under Chapter 28, specifically heading 2826. Furthermore, crushed or ground fluorspar that has undergone further processing beyond simple crushing, such as calcining or other chemical treatments that alter its fundamental character, would also be excluded, as Chapter 25 generally covers mineral products in their crude or simply prepared forms.
What are common classification mistakes for HS 252922?
A common error is misinterpreting the "more than 97%" purity threshold, leading to incorrect classification of lower-grade fluorspar. Importers sometimes classify fluorspar with, for example, 96.5% calcium fluoride content under 252922, when it correctly belongs in 252921. Another frequent mistake involves classifying synthetic or chemically pure calcium fluoride under this heading, rather than under Chapter 28, which is a misapplication of General Interpretative Rule (GRI) 1, as the text of Chapter 25 explicitly covers "mineral products" and not pure chemical compounds. Accurate chemical analysis is therefore paramount to avoid these errors.
How should importers classify products under HS 252922?
The correct procedure for classifying products under HS 252922 involves obtaining a certified chemical analysis report for the fluorspar shipment, clearly stating the calcium fluoride content by weight. Importers and customs brokers must ensure this content is demonstrably "more than 97%." This documentation should be readily available for customs verification. If the purity is 97% or less, the product should be classified under HS 252921. For any synthetic or chemically pure calcium fluoride, classification must be directed to Chapter 28. Always refer to the latest WCO HS Explanatory Notes and national tariff schedules (e.g., USITC HTSUS, EU TARIC) for definitive guidance and any specific national rulings.

FAQ
What are the typical import duty rates for fluorspar classified under HS 2529.22, specifically 'Containing by weight more than 97 % of calcium fluoride'?
The Most Favored Nation (MFN) duty rates for fluorspar under HS 2529.22 are often very low or zero in many major importing countries due to its industrial importance. For example, the Harmonized Tariff Schedule of the United States (HTSUS) generally lists a 'Free' duty rate for this subheading. The EU TARIC database also frequently shows a 0.00% ad valorem duty rate for imports from most third countries. Some countries, however, may apply specific duties, such as a rate of '$5.51/t' as observed in certain tariff schedules. 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 fluorspar to be correctly classified under HS 2529.22?
The primary classification criterion for HS 2529.22 is the calcium fluoride (CaF2) content by weight. To be classified under this subheading, the fluorspar must contain more than 97% by weight of calcium fluoride. Fluorspar with 97% or less by weight of calcium fluoride would typically fall under HS 2529.21. Importers must ensure that laboratory analysis reports or certificates of analysis from the supplier clearly state the CaF2 content to support this classification. This distinction is critical as duty rates or other import requirements may differ between the two subheadings.
Are there any preferential duty rates available for fluorspar under HS 2529.22 through common trade agreements?
Yes, preferential duty rates, often resulting in a 0.00% ad valorem rate, are frequently available for fluorspar under HS 2529.22 when imported from countries with which the importing nation has a free trade agreement (FTA) or other preferential trade arrangements. For instance, imports into the United States from FTA partners like Mexico (under USMCA), Canada (under USMCA), or various other countries with FTAs often qualify for 'Free' duty rates, provided the goods meet the respective rules of origin. Similarly, the EU offers preferential rates under agreements like the Generalized System of Preferences (GSP) or specific FTAs. Importers must ensure they have a valid Certificate of Origin (e.g., EUR.1, Form A, or specific FTA certificate) to claim these preferential tariffs.
What specific documentation is typically required for importing fluorspar under HS 2529.22?
Standard import documentation for fluorspar under HS 2529.22 includes a commercial invoice, packing list, bill of lading or air waybill, and a certificate of origin (if claiming preferential duty rates). Crucially, due to the specific calcium fluoride content requirement for this subheading, importers should also obtain a Certificate of Analysis (CoA) or a laboratory report from the supplier. This document should explicitly state the percentage by weight of calcium fluoride, confirming it is 'more than 97%'. Customs authorities may request this documentation to verify the classification and ensure compliance with chemical content regulations.
