HS 292620 1-Cyanoguanidine (dicyandiamide)

Quick Answer: HS code 292620 specifically covers 1-Cyanoguanidine, commonly known as dicyandiamide. This organic chemical compound is a nitrile derivative, primarily used as a raw material in the production of melamine, resins, pharmaceuticals, and fertilizers. For importers and exporters, understanding the varying duty rates is crucial. The UK applies a 6.00% ad valorem duty, while the EU TARIC system shows a 6.50% ad valorem rate. In the United States, the duty rate is generally Free, though specific trade programs or Section 301 tariffs (e.g., on goods from China) could impose an additional 25% ad valorem duty, significantly impacting landed costs. Importers should verify the country of origin and any applicable trade remedies to determine the precise duty liability.

How to Classify This HS Code?

What products does HS 292620 cover?

This subheading covers 1-Cyanoguanidine, commonly known as dicyandiamide (DCDA). Dicyandiamide is an organic chemical compound with the chemical formula C2H4N4, characterized by its nitrile functional group and its guanidine structure. It is specifically enumerated within the Harmonized System (HS) Nomenclature under Heading 2926, which covers "Nitrile-function compounds." The WCO Explanatory Notes for Chapter 29 and the official USITC Harmonized Tariff Schedule (HTS) and EU TARIC system confirm that this subheading is reserved exclusively for this distinct chemical compound, ensuring precise classification for trade purposes globally.

What falls outside HS 292620?

The following products are excluded from HS 292620: polymers of dicyandiamide, which would typically be classified in Chapter 39 if they meet the definition of plastics, or other chapters depending on their specific form and use. For instance, dicyandiamide-formaldehyde resins, used as textile auxiliaries or in laminates, are classified under Heading 3909. Additionally, mixtures containing dicyandiamide, where the dicyandiamide is not the predominant component by weight and does not impart the essential character, would be classified elsewhere, often in Chapter 38 as miscellaneous chemical products or in other chapters based on their function.

What are common classification mistakes for HS 292620?

A common error is misclassifying dicyandiamide when it is part of a mixture or formulation, rather than in its pure form. Importers sometimes incorrectly apply HS 292620 to preparations where dicyandiamide is merely an ingredient, even if it's a significant one, without considering General Interpretative Rule (GRI) 3(b) which dictates classification by essential character for mixtures. Another mistake is confusing dicyandiamide with its derivatives or related compounds that fall under other subheadings within Chapter 29, such as other nitrile-function compounds or guanidine salts, which have distinct chemical structures and classification provisions.

How should importers classify products under HS 292620?

The correct procedure for classifying products under HS 292620 involves first verifying the chemical identity of the product through laboratory analysis or supplier documentation, confirming it is indeed 1-Cyanoguanidine (dicyandiamide) with the specified chemical structure. Importers and customs brokers should ensure the product is in its unmixed, pure form, or if a mixture, that dicyandiamide constitutes the essential character according to GRI 3(b). Consulting the WCO Explanatory Notes for Heading 2926 and cross-referencing with the USITC HTS or EU TARIC system for any specific national rulings or additional notes is crucial to ensure accurate and compliant classification, avoiding potential delays or penalties.

FAQ

What is the import duty rate for 1-Cyanoguanidine (dicyandiamide) under HS 2926.20 in key markets, and are there preferential rates available?

The Most Favored Nation (MFN) duty rate for 1-Cyanoguanidine (dicyandiamide) (HS 2926.20) varies significantly by importing country. For example, the United States generally applies a 'Free' duty rate for this subheading, as per the Harmonized Tariff Schedule of the United States (HTSUS) 2926.20.00. The European Union's TARIC database indicates an MFN duty rate of 6.50% ad valorem for goods classified under CN code 2926 20 00. The UK Global Tariff also lists a 6.50% ad valorem duty rate for HS 2926.20.00. However, preferential duty rates may apply under various free trade agreements (FTAs). For instance, imports into the EU or UK from countries with which they have FTAs (e.g., GSP, EPA, or comprehensive FTAs) could be eligible for reduced or 'Free' duty, provided the rules of origin are met and proper documentation (e.g., EUR.1, GSP Form A, or origin declaration) is provided. Importers should consult the specific trade agreement and the customs tariff of the importing country for definitive preferential rates and origin requirements.

What are the key classification criteria for 1-Cyanoguanidine (dicyandiamide) under HS 2926.20, and what are common misclassification pitfalls?

1-Cyanoguanidine, commonly known as dicyandiamide (DCD), is classified under HS subheading 2926.20 as '1-Cyanoguanidine (dicyandiamide)'. This classification is straightforward as the subheading specifically names the chemical. Chapter 29 of the Harmonized System covers 'Organic chemicals', and heading 2926 covers 'Nitrile-function compounds'. Dicyandiamide is a nitrile-function compound with the chemical formula C2H4N4. The primary classification criterion is the chemical identity and purity of the product. Misclassification pitfalls typically arise if the product is part of a mixture or preparation. If dicyandiamide is mixed with other substances and is no longer a pure or nearly pure chemical compound, it may fall into other headings, such as those for chemical preparations (e.g., Chapter 38), depending on its function and composition. Importers must ensure that the product being declared is indeed 1-Cyanoguanidine (dicyandiamide) in its unmixed or principal form to correctly apply HS 2926.20. A Certificate of Analysis (CoA) is often crucial to confirm the chemical identity and purity.

What specific documentation is required for importing 1-Cyanoguanidine (dicyandiamide) under HS 2926.20, beyond standard shipping documents?

Beyond standard shipping documents such as the commercial invoice, packing list, and bill of lading/air waybill, importers of 1-Cyanoguanidine (dicyandiamide) under HS 2926.20 should be prepared to provide a Certificate of Analysis (CoA) or a Safety Data Sheet (SDS). A CoA confirms the chemical composition, purity, and specifications of the product, which can be critical for customs to verify the correct HS classification and ensure compliance with any chemical-specific regulations. An SDS provides essential information on potential hazards, safe handling, and emergency procedures, which may be required by regulatory bodies (e.g., EPA in the US, ECHA in the EU) for chemical imports. If claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin (e.g., EUR.1, GSP Form A, or a self-certification by the exporter) is mandatory. Depending on the end-use or specific national regulations, additional permits or licenses related to chemical import control might be necessary, though dicyandiamide is generally not considered a highly restricted chemical.

How do major trade agreements like the USMCA or EU-Vietnam FTA impact the import of 1-Cyanoguanidine (dicyandiamide) under HS 2926.20?

Major trade agreements can significantly impact the import of 1-Cyanoguanidine (dicyandiamide) by offering preferential duty treatment. For instance, under the United States-Mexico-Canada Agreement (USMCA), goods originating from Mexico or Canada and classified under HTSUS 2926.20.00 would typically be eligible for 'Free' duty entry into the United States, provided they meet the agreement's rules of origin. Similarly, the EU-Vietnam Free Trade Agreement (EVFTA) could allow for reduced or 'Free' duty entry for 1-Cyanoguanidine (dicyandiamide) (CN 2926 20 00) originating from Vietnam into the EU, provided the specific rules of origin for this product are satisfied. Importers must verify the specific origin criteria for HS 2926.20 within the relevant trade agreement, as these often involve requirements for the percentage of originating materials or specific manufacturing processes. Proper documentation, such as a certificate of origin or an origin declaration, is essential to claim these preferential rates. Failure to meet origin requirements or provide correct documentation will result in the application of the MFN duty rate.
