HS 030791 Other
Quick Answer: Other aquatic invertebrates imported under HS 030791 enter the UK at 10.00%, the EU at 11.00%, and the US duty-free. This residual classification applies to mollusks and crustaceans not specifically listed in preceding subheadings of heading 0307, such as certain types of sea urchins or sea cucumbers. Importers should verify the precise nature of the aquatic invertebrate to ensure correct classification, as specific species may have unique tariff treatments. According to CustomTariffs data, while the US offers duty-free entry, significant ad valorem duties apply in the EU and UK markets.

How to Classify This HS Code?
What products does HS 030791 cover?
This subheading covers "Other" molluscs and aquatic invertebrates, not elsewhere specified or included within heading 0307. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this includes a diverse range of marine and freshwater organisms that do not fit into the more specific categories of oysters, mussels, scallops, or clams. For instance, the US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this category encompasses items like sea urchins, jellyfish, and other less commonly traded invertebrates, provided they are intended for human consumption or other specified uses.
What falls outside HS 030791?
The following products are excluded from HS 030791: live molluscs and aquatic invertebrates of the specific types enumerated in subheadings 0307.11 through 0307.60, such as oysters, mussels, scallops, and clams. Additionally, any aquatic invertebrates that are not molluscs, such as crustaceans (e.g., shrimp, crab) or echinoderms not specifically listed, are classified under different headings. Products preserved by means other than simple refrigeration, such as those canned, dried, or salted, are also generally excluded and fall under Chapter 16 of the HS.
What are common classification mistakes for HS 030791?
A common error is misclassifying processed or preserved forms of "other" molluscs and aquatic invertebrates. For example, if sea urchin roe (uni) is preserved in brine or pasteurized, it may no longer qualify for 0307.91 and could be subject to Chapter 16. Furthermore, confusion can arise with live aquatic animals not intended for human consumption, which may fall under Chapter 01. Adherence to General Interpretative Rule 1 and Rule 3 is crucial to ensure accurate classification based on the most specific description and essential character.
How should importers classify products under HS 030791?
The correct procedure for classifying products under HS 030791 involves a thorough examination of the product's nature, form, and intended use. Importers and customs brokers must first determine if the product is a mollusc or aquatic invertebrate. If it is, they must then ascertain if it is specifically listed in other subheadings of 0307. If it is not, and it is live or simply chilled/frozen, then 0307.91 is the appropriate classification. Consulting the official WCO HS Explanatory Notes and national tariff databases like the USITC HTS or EU TARIC is essential for definitive guidance.
How is the duty calculated for products under HS 030791?
A shipment of 100 kilograms of live sea urchins, declared at a customs value of $500 USD, would attract a US duty of $50.00. This is calculated using the USITC Harmonized Tariff Schedule's Most Favored Nation (MFN) duty rate of 10% ad valorem, applied to the declared customs value ($500 USD × 10% = $50.00). If the product were subject to a specific duty, for example, $0.50 per kilogram, the duty would be $50.00 (100 kg × $0.50/kg).
Which trade agreements reduce duties for HS 030791?
Several free trade agreements may reduce the applicable duty rate for HS 030791, including the United States-Mexico-Canada Agreement (USMCA), which can result in a Free duty rate for qualifying originating goods from Canada and Mexico. The EU's Generalized Scheme of Preferences (GSP) may offer reduced or Free duty rates for originating goods from certain developing countries. Documentation required typically includes a self-certified origin statement for USMCA or a EUR.1 movement certificate for certain EU preferential arrangements, depending on the specific agreement and origin country.

FAQ
What are the typical import duty rates for HS code 030791, covering 'Other' aquatic invertebrates?
HS code 030791 falls under 'Other aquatic invertebrates, live, fresh, chilled, frozen, dried, salted or in brine, whether or not cooked before or during the processing'. The Most Favored Nation (MFN) duty rates can vary. For instance, the United States typically applies a 10.00% ad valorem duty rate. The European Union's TARIC system and the UK Trade Tariff may have different rates, often subject to specific trade agreements. It is crucial to consult the latest official tariff schedules for the importing country to determine the exact applicable duty.
How is the classification of 'Other' aquatic invertebrates under HS 030791 determined?
HS code 030791 is a residual category for aquatic invertebrates not specifically listed under other subheadings of 0307. This includes a wide array of organisms such as sea urchins, jellyfish, sea cucumbers, and other marine invertebrates that do not fit into more specific classifications like mollusks (0307.11-0307.69) or crustaceans (0306). Classification relies on the biological and zoological identity of the product. Importers must ensure their product is not classifiable elsewhere before using this code.
What documentation is typically required for importing goods classified under HS 030791?
Standard import documentation for HS 030791 includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the specific product, additional documents may be necessary. These can include a certificate of origin, import permits, health certificates or phytosanitary certificates issued by the competent authority of the exporting country to ensure the product meets sanitary and phytosanitary standards. For live aquatic animals, specific import licenses might be required.
How do trade agreements, such as those with the US, EU, or UK, affect the duty rates for HS 030791?
Trade agreements can significantly reduce or eliminate duties for goods classified under HS 030791 if the product originates from a country that is a party to such an agreement. For example, under the USMCA (United States-Mexico-Canada Agreement), goods originating from Canada or Mexico may benefit from preferential duty rates, potentially even duty-free entry, provided they meet the rules of origin. Similarly, agreements between the EU and third countries, or the UK's trade agreements post-Brexit, can offer reduced tariffs. Importers must verify the origin of their goods and consult the relevant preferential tariff schedules to claim these benefits.
Can you provide an example of how import duty is calculated for HS 030791?
Let's assume an importer brings 1,000 kilograms of frozen sea cucumbers (classified under HS 030791) into the United States. The MFN duty rate is 10.00% ad valorem. If the declared value of the sea cucumbers is $5,000 USD, the duty calculation would be: Duty = Value × Duty Rate = $5,000 USD × 10.00% = $500 USD. In this scenario, the importer would pay $500 USD in import duties. It's important to note that some tariffs might also include specific duties (e.g., per kilogram) or a combination of ad valorem and specific duties, which would alter the calculation.
