HS 030691 Other

Quick Answer: Crustaceans, not live, fresh, chilled, frozen, salted, dried, or smoked, imported under HS 030691 enter the UK at 12.00%, the EU at 12.50%, and the US duty-free. This residual classification applies to various processed or prepared crustaceans that do not fit into more specific subheadings within Chapter 03 of the Harmonized System. Importers should carefully review the specific preparation method and form of the crustaceans to ensure accurate classification, as misclassification can lead to incorrect duty assessments. CustomTariffs aggregates this data, highlighting potential duty cost differences across major trading blocs for these less commonly specified items.

What products does HS 030691 cover?

This subheading covers other crustaceans, whether in shell or not, live, fresh, chilled, frozen, dried, salted or in brine, which are not specified in subheadings 0306.11 to 0306.90. According to the World Customs Organization's Harmonized System Nomenclature, this residual category captures crustaceans that do not fit into the more specific classifications for shrimp, prawns, lobsters, crabs, and other defined groups within Heading 0306. For example, certain less common species of aquatic invertebrates that are classified as crustaceans would fall here if not otherwise enumerated.

What falls outside HS 030691?

The following products are excluded from HS 030691: live, fresh, chilled, frozen, dried, salted or in brine crustaceans that are specifically classified under other subheadings of Heading 0306, such as shrimp and prawns (0306.13), lobsters and other sea crayfish (0306.11), and crabs (0306.12). Additionally, molluscs (Chapter 0307), aquatic invertebrates not classified as crustaceans, and prepared or preserved crustaceans (Chapter 1605) are not covered by this subheading.

What are common classification mistakes for HS 030691?

A common error is misclassifying prepared or preserved crustaceans under this subheading. According to General Interpretative Rule 1, classification is determined by the terms of the headings and any relative Section or Chapter Notes. If crustaceans have undergone processing beyond simple preservation (e.g., cooking, seasoning, or incorporation into a dish), they are typically classified under Chapter 16, specifically Heading 1605, rather than remaining in Chapter 03. This distinction is crucial for accurate duty assessment.

How should importers classify products under HS 030691?

The correct procedure for classifying products under HS 030691 involves a thorough examination of the product's form and any processing it has undergone. Importers and customs brokers must first consult the WCO Harmonized System Explanatory Notes for Heading 0306 to understand the scope of crustaceans. If the product is a crustacean not specifically listed in subheadings 0306.11 through 0306.90 and is not prepared or preserved under Chapter 16, then 0306.91 is the appropriate classification.

How is the duty calculated for products under HS 030691?

A shipment of 100 kilograms of dried, unshelled barnacles, 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 (10% of $500 = $50.00). It is imperative to verify the specific MFN rate applicable at the time of import, as these can change annually.

Which trade agreements reduce duties for HS 030691?

Several free trade agreements may reduce the applicable duty rate for HS 030691, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada and Mexico can enter the United States duty-free. To claim this preference, a valid origin declaration or certificate of origin is typically required. For goods originating from countries benefiting from the Generalized System of Preferences (GSP) in the EU, a EUR.1 movement certificate might be necessary to claim preferential duty rates, often reduced to 0% or a lower percentage.

FAQ

What is the import duty for HS code 030691, specifically for 'Other' crustaceans, live, fresh, chilled, frozen, dried, salted or in brine?

The Most Favored Nation (MFN) duty rate for HS code 030691 is Free. However, preferential duty rates may apply under various trade agreements. For instance, under the US-Korea Free Trade Agreement (KORUS FTA), the duty rate is also Free. It is crucial to consult the specific tariff schedule of the importing country and any applicable trade agreements to determine the precise duty. For example, in the United States, the Harmonized Tariff Schedule (HTS) maintained by the US International Trade Commission (USITC) lists the duty rate. In the EU, the TARIC database provides comprehensive tariff information. For the UK, the UK Trade Tariff is the definitive source.

How is the duty calculated for HS code 030691 if a specific rate applies, and what documentation is typically required?

While the MFN duty for HS 030691 is Free, if a specific rate were applicable (e.g., a hypothetical 5% ad valorem rate for a specific scenario not covered by the Free MFN), the duty would be calculated as 5% of the declared customs value of the goods. For example, if 100 kg of 'other' crustaceans valued at $500 were imported, and assuming a hypothetical 5% ad valorem duty, the duty would be $500 * 0.05 = $25. Documentation typically required includes a commercial invoice, packing list, bill of lading or air waybill, and potentially a certificate of origin if preferential treatment is claimed. Specific import licenses or health certificates may also be required depending on the country of import and the specific type of crustacean.

What are the classification criteria for goods falling under HS code 030691, 'Other' crustaceans?

HS code 030691 covers crustaceans (such as crabs, lobsters, shrimp, prawns, and crayfish) that are not specifically listed under other subheadings within Chapter 03 of the Harmonized System. This includes live, fresh, chilled, frozen, dried, salted, or in brine crustaceans that do not fit into more specific categories like 'shrimp and prawns' (0306.16) or 'crabs' (0306.11, 0306.21). The classification hinges on the biological classification of the crustacean and its condition (live, fresh, etc.), provided it's not otherwise specified. The World Customs Organization (WCO) provides Explanatory Notes that clarify the scope of each heading and subheading.

Which common trade agreements might offer preferential duty rates for HS code 030691, and how can importers verify these rates?

Several trade agreements can offer preferential duty rates, often resulting in Free entry for HS code 030691. Examples include the US-Korea Free Trade Agreement (KORUS FTA), the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), and various Free Trade Agreements (FTAs) the EU has with third countries. To verify these rates, importers and customs brokers should consult the official tariff database of the importing country (e.g., USITC HTS, EU TARIC, UK Trade Tariff) and input the HS code along with the country of origin. A valid Certificate of Origin is typically required to claim preferential treatment under these agreements.
