How to Classify This HS Code?
What products does HS 710491 cover?
This subheading covers other synthetic or reconstructed precious or semi-precious stones, whether or not worked or graded, but not strung, mounted or set. According to the World Customs Organization's Harmonized System Nomenclature, this category encompasses synthetic or reconstructed stones that do not fit into more specific subheadings within Heading 7104. For example, this includes synthetic rubies, sapphires, and emeralds that have been cut, polished, or otherwise processed but are not yet incorporated into jewelry or other finished articles. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this broad inclusion of non-specified synthetic and reconstructed stones.
What falls outside HS 710491?
The following products are excluded from HS 710491: natural precious or semi-precious stones (which are classified under Heading 7103), synthetic or reconstructed stones that are strung, mounted, or set (typically classified in Chapter 71, but in specific headings for jewelry or imitation jewelry), and materials that are not considered stones, even if they resemble them. For instance, glass imitations of gemstones, unless they are specifically defined as synthetic or reconstructed stones for classification purposes, would fall under different headings, often within Chapter 70. Also, rough, unworked synthetic stones are generally classified under more specific subheadings of 7104.
What are common classification mistakes for HS 710491?
A common error is misclassifying synthetic or reconstructed stones that are already strung, mounted, or set. 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 stone is incorporated into a piece of jewelry, it will be classified as jewelry, not as a loose stone under 710491. Another mistake is confusing synthetic stones with natural stones or with imitations made of glass or plastic, which have different tariff classifications and duty rates. For example, a synthetic sapphire is classified here, while a natural sapphire is under 7103.
How should importers classify products under HS 710491?
The correct procedure for classifying products under HS 710491 involves a thorough examination of the product's composition and form. Importers and customs brokers must first determine if the stone is natural or synthetic/reconstructed. If it is synthetic or reconstructed, they must then ascertain if it is worked or graded. Crucially, they must verify that the stones are not strung, mounted, or set. Consulting the WCO HS Nomenclature, the USITC HTS, or the EU TARIC database for specific explanatory notes and rulings is essential. If uncertainty remains, a binding ruling from the customs authority is recommended.
How is the duty calculated for products under HS 710491?
A parcel of 100 carats of synthetic cubic zirconia, declared at a customs value of $500 USD, would attract a US duty of $25.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value. The calculation is $500 USD × 5.0% = $25.00. This is calculated using the MFN rate published in the USITC Harmonized Tariff Schedule for subheading 710491.0000. Note that specific countries may have different rates under preferential trade agreements.
Which trade agreements reduce duties for HS 710491?
Several free trade agreements may reduce the applicable duty rate for HS 710491, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) program allows for duty-free entry for eligible goods from certain developing countries, such as India and Thailand. 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 agreement and jurisdiction.

FAQ
What is the import duty for HS code 710491 (Other non-synthetic, non-natural gemstones)?
The Most Favored Nation (MFN) duty rate for HS code 710491 in the United States is 0.00% ad valorem. For the European Union, under the TARIC system, the duty rate is also Free. The UK Trade Tariff lists a duty rate of Free for this classification. It is crucial to verify specific preferential rates under trade agreements, as these can offer further reductions or duty-free entry. Always consult the latest official tariff schedules for the importing country.
How is HS code 710491 defined, and what types of gemstones fall under 'Other'?
HS code 710491 covers 'Other' gemstones that are neither synthetic nor reconstituted, and are not diamonds. This category typically includes natural gemstones that do not have a more specific classification within Chapter 71 of the Harmonized System. Examples may include certain types of natural quartz varieties (e.g., amethyst, citrine, smoky quartz) if not specifically classified elsewhere, or other natural stones used as gemstones that do not fit into categories like precious stones (rubies, sapphires, emeralds) or pearls. The key is that they are natural, non-synthetic, non-reconstituted, and not diamonds. Classification is based on the physical characteristics and origin of the material.
What documentation is typically required for importing goods classified under HS 710491?
When importing goods under HS code 710491, standard import documentation is required. This includes a commercial invoice detailing the value, quantity, and description of the gemstones; a packing list; and a bill of lading or air waybill. Depending on the country of import and the specific nature of the gemstones, additional documentation might be necessary. This could include a certificate of origin to claim preferential tariff treatment, and potentially a gemological report from a recognized laboratory to verify the authenticity and nature of the stones, especially if they are valuable or their classification is complex. Importers should always confirm specific requirements with the customs authority of the destination country.
How is the duty calculated for HS 710491 if a duty were applicable, and can you provide an example?
While HS code 710491 often carries a 0.00% duty rate in major markets like the US, EU, and UK, if a duty were applicable (e.g., a specific trade agreement or a different country's tariff), it would typically be calculated on an ad valorem basis. This means the duty is a percentage of the declared customs value of the goods. For example, if a country imposed a 10% ad valorem duty on HS 710491, and you imported gemstones with a declared customs value of $10,000, the duty calculation would be: $10,000 (Customs Value) × 10% (Duty Rate) = $1,000 (Duty Amount). Importers and brokers must ensure accurate valuation and apply the correct duty rate based on the origin and destination.
Which trade agreements might offer preferential duty rates for HS 710491, and how can importers verify eligibility?
Many trade agreements, such as the United States-Mexico-Canada Agreement (USMCA) or various Free Trade Agreements (FTAs) the EU and UK have with third countries, could potentially offer preferential duty rates, including duty-free entry, for goods classified under HS 710491, provided the goods meet the rules of origin stipulated in the agreement. To verify eligibility, importers and customs brokers must: 1. Consult the specific trade agreement text to understand the rules of origin for Chapter 71 goods. 2. Obtain a valid Certificate of Origin from the exporter, issued by the competent authority in the exporting country, certifying that the goods meet the origin criteria. 3. Ensure the goods are shipped directly from the partner country to the importing country. 4. Check the importing country's tariff schedule for specific preferential codes and requirements. The USITC, EU TARIC, and UK Trade Tariff websites are valuable resources for checking preferential rates.
