HS 710231 Non-industrial

Quick Answer: Diamonds, other than industrial diamonds, imported under HS 710231 enter the UK at 0.00%, the EU at 0.00%, and the US duty-free under the MFN rate. This classification specifically covers non-industrial diamonds, which are typically used for jewelry or other non-manufacturing purposes. Importers should ensure that the diamonds are not intended for industrial applications, as those fall under a different HS code. According to CustomTariffs data, these major markets currently offer duty-free entry for this category, simplifying trade for polished and rough non-industrial diamonds.

How to Classify This HS Code?

```html

What products does HS 710231 cover?

This subheading covers diamonds, whether or not worked, but not mounted or set, which are not suitable for use in industry. According to the World Customs Organization's Harmonized System Nomenclature, this category specifically includes natural or synthetic diamonds that have been cut or polished but are not of a quality or size suitable for industrial applications, such as those used in jewelry. The USITC Harmonized Tariff Schedule (HTS) and EU TARIC further define these as non-industrial diamonds primarily intended for gem purposes.

What falls outside HS 710231?

The following products are excluded from HS 710231: industrial diamonds, which are classified under HS 710239, and diamonds that are mounted or set in jewelry or other articles, which fall under Chapter 71. Also excluded are rough diamonds not yet worked, which are classified under HS 710210. Diamonds that have undergone specific industrial treatments or are intended for use in cutting tools or abrasives are also not covered by this subheading.

What are common classification mistakes for HS 710231?

A common error is misclassifying industrial diamonds as non-industrial diamonds, or vice versa, based on subtle differences in quality or intended use. General Rule of Interpretation (GRI) 1 of the Harmonized System emphasizes that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Importers must carefully assess the intended application and physical characteristics to distinguish between gem-quality and industrial-grade diamonds, often requiring expert appraisal.

How should importers classify products under HS 710231?

The correct procedure for classifying products under HS 710231 involves a thorough examination of the diamonds' characteristics and intended use. Importers and customs brokers must consult the official HS Nomenclature, relevant national tariff schedules (e.g., USITC HTS, EU TARIC), and any supporting documentation, such as gemological reports. This assessment should confirm that the diamonds are worked, not mounted or set, and are not suitable for industrial applications, thereby meeting the criteria for non-industrial diamonds.

How is the duty calculated for products under HS 710231?

A parcel of 10 polished, non-industrial diamonds weighing 5 carats in total and declared at a customs value of $5,000 USD would attract a US duty of $0.00. This is calculated using the Most Favored Nation (MFN) rate of 0% ad valorem published in the USITC Harmonized Tariff Schedule for HS 710231. The duty is determined by applying the specified ad valorem rate to the declared customs value, resulting in zero duty for this specific scenario.

Which trade agreements reduce duties for HS 710231?

Several free trade agreements may reduce the applicable duty rate for HS 710231, including the United States-Mexico-Canada Agreement (USMCA), which can result in a preferential rate of Free for goods originating from Canada and Mexico. The Generalized System of Preferences (GSP) may also offer duty-free entry for eligible goods from certain developing countries. Documentation required typically includes a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries.

FAQ

What are the import duty rates for HS code 710231, covering 'non-industrial' diamonds?

For HS code 710231, which covers 'other' diamonds (i.e., non-industrial, unset, and not otherwise worked), the duty rates are generally preferential and often free. For example, under the United States' Harmonized Tariff Schedule (USHTS), the Most Favored Nation (MFN) rate is 0.00%. Similarly, the European Union's TARIC system and the UK Trade Tariff also list these diamonds as free of duty under their standard import regimes. Always consult the specific tariff schedule of the importing country for the most current rates.

How are diamonds classified under HS code 710231 as 'non-industrial'?

HS code 710231 specifically applies to diamonds that are not intended for industrial use. This typically includes natural diamonds that are rough, cut, or polished, but are not suitable for use in machinery or other industrial applications due to their quality, size, or clarity. The World Customs Organization (WCO) Explanatory Notes to Chapter 71 provide detailed guidance. Key distinguishing factors often relate to the diamond's gem quality and potential for use in jewelry. Industrial diamonds are classified under HS code 710210.

What documentation is typically required for importing goods under HS code 710231?

Importing diamonds under HS code 710231 often requires specific documentation beyond standard customs declarations. This may include a certificate of origin, a detailed invoice specifying the carat weight, cut, color, and clarity of the diamonds, and potentially a Kimberley Process certificate if the diamonds are rough and originating from participating countries, to ensure they are conflict-free. Importers should verify the exact requirements with the customs authority of the destination country.

Do any major trade agreements offer preferential duty rates for diamonds classified under HS code 710231?

While many countries unilaterally offer duty-free treatment for non-industrial diamonds (HS 710231) as a trade facilitation measure, specific preferential rates under trade agreements can vary. For instance, agreements like the Generalized System of Preferences (GSP) might offer reduced or zero duties for eligible developing countries. However, given the already low or free MFN rates in major markets like the US, EU, and UK, the impact of trade agreements on this specific code might be less pronounced than for other goods. It is crucial to check the rules of origin and specific provisions of any applicable trade agreement.

Can you provide an example of how import duty is calculated for HS code 710231?

Since the duty rate for HS code 710231 is typically 0.00% ad valorem in most major markets, the calculation results in zero duty. For example, if a shipment of 10 carats of non-industrial diamonds valued at $50,000 is imported into the US, and the MFN duty rate is 0.00%: Duty = (Value × Duty Rate) = ($50,000 × 0.00%) = $0. In scenarios where a small duty might apply (e.g., specific excise taxes or processing fees not classified as import duty), the calculation would follow the specific rate and basis (ad valorem, specific, or compound) outlined by the importing country's customs authority.
