HS 310229 Other
Quick Answer: Other inorganic nitrogen fertilizers imported under HS 310229 enter the UK at rates up to 6.50%, the EU with no specific ad valorem duty listed, and the US duty-free under the MFN rate. This residual classification applies to inorganic nitrogen fertilizers not specifically listed elsewhere in Chapter 31, such as ammonium nitrate, ammonium sulphate, and urea, when they do not fit more precise descriptions. Importers should verify specific product composition against the detailed tariff notes for each jurisdiction to ensure correct classification and avoid potential duty discrepancies.

How to Classify This HS Code?
What products does HS 310229 cover?
This subheading covers "Other" mineral or chemical fertilizers, nitrogenous, not specified or included elsewhere within Heading 3102. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category is for nitrogenous fertilizers that do not fit the more specific subheadings within 3102, such as ammonium nitrate or urea. For example, this could include certain complex nitrogenous fertilizers or mixtures of nitrogenous fertilizers with other fertilizing substances not specifically enumerated. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database provide further detail on the scope of this residual category.
What falls outside HS 310229?
The following products are excluded from HS 310229: all mineral or chemical fertilizers that are specifically enumerated under other subheadings of Heading 3102, such as ammonium nitrate (3102.10), urea (3102.21), ammonium sulphate (3102.21), and ammonium phosphates (3105.30, 3105.40). Also excluded are organic fertilizers (Chapter 31, Note 2), animal or vegetable fertilizers, whether or not mixed together but not chemically purified, and fertilizers containing the elements phosphorus or potassium. For instance, diammonium phosphate would be classified under 3105.30, not 310229.
What are common classification mistakes for HS 310229?
A common error is misclassifying complex fertilizers or mixtures containing nitrogen with other nutrients like phosphorus or potassium. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. If a product contains nitrogen as its primary fertilizing component but also includes significant amounts of other primary nutrients, it may fall under Heading 3105 (Fertilisers). Importers must carefully examine the composition and intended use to ensure accurate classification, especially when dealing with blended products.
How should importers classify products under HS 310229?
The correct procedure for classifying products under HS 310229 involves a thorough analysis of the product's chemical composition and its primary fertilizing function. Importers and customs brokers must consult the official HS Nomenclature, relevant national tariff schedules (e.g., USITC HTS, EU TARIC, UK Trade Tariff), and any applicable Explanatory Notes. This includes verifying that the product is a nitrogenous fertilizer and does not meet the criteria for any more specific subheading within Heading 3102 or other headings in Chapter 31. A detailed product specification sheet is crucial for this process.
How is the duty calculated for products under HS 310229?
A shipment of 10 metric tons of ammonium chloride-based fertilizer, declared at a customs value of $5,000 USD, would attract a US duty of $150.00. Assuming a Most Favored Nation (MFN) duty rate of 3.0% ad valorem, the calculation is $5,000 USD × 3.0% = $150.00. This is calculated using the MFN rate published in the USITC Harmonized Tariff Schedule for a product fitting the "Other" category within nitrogenous fertilizers, provided it is not covered by a more specific classification. Note that some countries may apply specific rates based on quantity.
Which trade agreements reduce duties for HS 310229?
Several free trade agreements may reduce the applicable duty rate for HS 310229, including the United States-Mexico-Canada Agreement (USMCA), which can result in a Free duty rate for originating goods from Canada and Mexico. The Generalized System of Preferences (GSP) also offers reduced or Free duty rates for eligible products from designated developing countries, such as Vietnam. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific jurisdiction and agreement requirements.

FAQ
What are the typical import duty rates for HS code 310229 (Other inorganic nitrogen fertilizers)?
The import duty rates for HS code 310229, which covers 'Other' inorganic nitrogen fertilizers not specified elsewhere in heading 3102, vary by country. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) duty rate is 6.50% ad valorem. Under the EU's TARIC system, the rate is often free for many origins, but specific rates can apply depending on the country of origin and any applicable trade agreements. The UK Trade Tariff also lists specific rates, which can be free or subject to tariffs based on origin. Always consult the specific tariff schedule of the importing country for the definitive rate.
How is the import duty for HS code 310229 calculated, and can you provide an example?
The duty calculation for HS code 310229 typically depends on whether the duty is ad valorem (a percentage of the value) or specific (a fixed amount per unit of quantity), or a combination. For an ad valorem duty, the calculation is straightforward: Duty = Value of Goods × Duty Rate. For example, if the MFN duty rate in the US is 6.50% and you import 10,000 kg of fertilizer valued at $5,000 USD, the duty would be $5,000 USD × 6.50% = $325 USD. If a specific duty component exists (e.g., per metric ton), it would be added. Always verify the duty basis (ad valorem, specific, or compound) from the importing country's tariff schedule.
What documentation is typically required for importing goods classified under HS code 310229?
For importing goods under HS code 310229, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Additionally, depending on the importing country's regulations and the specific product, a certificate of origin may be necessary, especially if preferential duty rates are claimed. Some countries may require specific phytosanitary certificates or analysis reports to ensure the product meets agricultural or environmental standards. Importers and customs brokers should verify the exact requirements with the customs authority of the destination country.
Are there preferential duty rates available for HS code 310229 under common trade agreements?
Yes, preferential duty rates for HS code 310229 are often available under various trade agreements. For instance, goods originating from countries that are part of the EU's Generalized Scheme of Preferences (GSP) or specific Free Trade Agreements (FTAs) with the EU may benefit from reduced or zero duty rates. Similarly, the US has FTAs with numerous countries that could offer preferential treatment. The UK also has a range of trade agreements post-Brexit. To claim these preferential rates, importers must typically provide a valid certificate of origin and ensure the goods meet the rules of origin stipulated in the respective trade agreement. Consulting the specific trade agreement and the importing country's tariff database is crucial.
What are the classification criteria to ensure a product falls under HS code 310229 ('Other' inorganic nitrogen fertilizers)?
HS code 310229 is a residual category for inorganic nitrogen fertilizers that are not specifically listed under other subheadings of heading 3102. Heading 3102 covers 'Mineral or chemical fertilizers, nitrogenous'. Therefore, to classify under 310229, the product must be an inorganic substance, primarily used for its nitrogen content to fertilize plants, and not be a nitrate of ammonia (310210), ammonium nitrate, whether or not in aqueous solution (310221), urea (310230), ammonium sulphate (310240), ammonium nitrate and ammonium sulphate mixtures (310250), calcium nitrate (310260), magnesium nitrate (310270), potassium nitrate (310280), or other mixtures (310290). Examples might include certain complex nitrogen compounds or specific blends not elsewhere specified. A detailed chemical analysis and understanding of the product's primary use are essential for correct classification.
