How to Classify This HS Code?

```html

What products does HS 680610 cover?

This subheading covers slag-wool, rock-wool, and similar mineral wools, including any intermixtures thereof, presented in bulk, sheets, or rolls. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, these materials are manufactured from molten slag or natural rocks, spun or blown into fine fibers. They are primarily used for thermal and acoustic insulation. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm that this classification applies to the raw, unfabricated forms of these insulating materials, such as loose fill insulation or pre-formed boards and batts.

What falls outside HS 680610?

The following products are excluded from HS 680610: finished articles incorporating mineral wool, such as insulated panels or prefabricated building components, which would be classified based on their overall character. Also excluded are other insulating materials not derived from slag or rock, such as fiberglass or cellulose insulation, which fall under different HS codes. For instance, fiberglass insulation is typically classified under HS 7019.39, and products that have undergone significant further processing beyond simple shaping into sheets or rolls are generally not covered.

What are common classification mistakes for HS 680610?

A common error is misclassifying products that have undergone significant further processing or are intended for specific applications. For example, if mineral wool is bonded with a resin to form rigid boards with a facing material, it might be classified under a more specific heading based on the composite nature of the product, rather than simply as mineral wool in sheets. According to General Rule of Interpretation (GRI) 3(b), composite goods are classified according to the material or component that gives them their essential character, which may not always be the mineral wool itself.

How should importers classify products under HS 680610?

The correct procedure for classifying products under HS 680610 involves a thorough examination of the product's composition and presentation. Importers and customs brokers must verify that the material is indeed slag-wool, rock-wool, or a similar mineral wool, and that it is presented in bulk, sheets, or rolls. Consulting the official tariff schedules of the importing country, such as the USITC HTS or the EU TARIC, and reviewing the relevant Explanatory Notes from the WCO is crucial. If the product is an intermixture, the proportions of the components should be confirmed.

How is the duty calculated for products under HS 680610?

A shipment of Rockwool insulation boards weighing 5,000 kilograms and declared at a customs value of $10,000 USD would attract a US duty of $500.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($10,000 USD × 0.05 = $500.00). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule for HS code 6806.10.0000.

Which trade agreements reduce duties for HS 680610?

Several free trade agreements may reduce the applicable duty rate for HS 680610, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating products from Canada and Mexico can enter the United States duty-free. To claim this preference, a self-certified origin statement is typically required. Additionally, the Generalized System of Preferences (GSP) may offer reduced or duty-free entry for eligible products from certain developing countries, requiring a GSP Form A. For EU countries, the preferential rate is often Free, with an EUR.1 movement certificate needed.

Import duty rates for HS code 680610 can vary significantly by country. For example, under the US Harmonized Tariff Schedule, the Most Favored Nation (MFN) rate is 3.9% ad valorem. In the European Union, under the TARIC system, the rate is 0.00% ad valorem. The United Kingdom's Trade Tariff also lists a 0.00% duty rate for this classification.

For instance, if a shipment of rock wool valued at $10,000 is imported into the United States, and the MFN duty rate of 3.9% applies, the import duty would be calculated as: $10,000 (Value) × 0.039 (Duty Rate) = $390.00. Always ensure the customs value is determined according to the importing country's valuation rules.

What are the classification criteria for goods under HS code 680610?

HS code 680610 covers 'Slag-wool, rock-wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls'. Classification hinges on the material being derived from slag, rock, or similar mineral substances that have been spun or blown into fibrous form, creating mineral wool. The product must be presented in bulk, sheets, or rolls. Products that are further processed into finished articles (e.g., insulation boards with facings) may fall under different HS codes. Referencing Explanatory Notes from the World Customs Organization (WCO) can provide further clarity on the scope of this heading.

Which trade agreements offer preferential duty rates for HS code 680610?

Several trade agreements can provide preferential duty rates for goods classified under HS 680610.

Similarly, the EU TARIC and UK Trade Tariff may list preferential rates under agreements with various countries or blocs. Importers must ensure they meet the rules of origin and have the necessary documentation (e.g., Certificate of Origin) to claim preferential treatment.

What documentation is typically required for importing goods under HS code 680610?
