Last update: July 24th, 2026 Source Updates on US Import Tariffs On Wednesday, April 2, 2025, US President Trump announced significant import tariffs affecting countries worldwide, specifying the rates each country would face. On April 9, 2025, he imposed a 90-day pause on these tariffs, which was later extended until August 1, 2025. On that date, the Trump administration introduced new tariffs applying to all countries. In september 2025, European diamonds were the only ones exempted from US imort tariffs worldwide. In February 2026, following a US Supreme Court ruling, President Trump introduced a temporary 10% import surcharge under Section 122 of the Trade Act of 1974, causing the temporary lapse of the 0% tariff exemption for European natural diamonds. This surcharge expired on 24 July 2026, since then,European natural diamonds have been exempted under the new Section 301 measures, restoring the 0% US import tariff. UPDATE 24 July 2026 At this time, the EU–US trade agreement is back in place, meaning EU-origin diamonds (polished in Antwerp) are under a 0% import tariff rate. This new ruling went into effect on Friday, July 24 2026. For the latest updates, subscribe to our WhatsApp channel. Consult our Tariffs FAQ Consult our Tariffs Practical Examples Download the complete list of diamond tariffs by country here: Diamond Tariffs by Country A complete list of all USA import tariff rates by country. Seperated by polished and rough diamonds. How does the US determine the origin of diamonds? Regardless of which tariffs are imposed and on which products, it is crucial to have clarity on what the measures are actually about and which imports/exports will be subject to these duties. Global trade rules determine the origin of diamonds as follows: Rough diamonds: The country where the stone was mined is considered its country of origin. Practical example 1: A rough diamond from a mine in Canada is therefore classified as a Canadian product and has been subject to President Trump's 10% import tariffs on Canadian goods since July 24. Practical example 2: A rough diamond mined in Canada, purchased by a Belgian company and subsequently sent to the US—for example, for a DOR Report by GIA*—falls under these import tariffs, meaning the recipient will have to pay a 10% import duty. *Review GIA-specific questions in our FAQ below Polished diamonds: The country where the diamond was processed/polished (WTO rules on “substantial transformation*”) is considered its country of origin. Practical example 1: A rough diamond from a mine in Canada that was sent to India for manufacturing is now considered an Indian diamond. If this diamond is then sent to the US, the recipient will have to pay a 10% import duty. Practical example 2: A rough diamond from a mine in Canada that was polished in Canada and sent to the US, will have an import tariff of 0% under the US-Mexico-Canada Agreement (USMCA). In WTO rules, "substantial transformation" determines a product's origin when it's not wholly obtained in a single country, meaning the country where the last significant manufacturing or processing occurred, giving the product its essential character, is considered the origin.  We expect the United States to follow these global trade rules. However, as this is the first time that import duties are levied on either side of the Atlantic, we cannot be fully certain. The US still needs to publish the regulations detailing the modalities of the import duties. Frequently Asked Questions Back to previous page Latest Updates What is the current US import tariff on polished diamonds from Belgium (EU)? Short Answer: 0% (Announced July 24th 2026, onwards) Does transit through Belgium change a diamond’s origin? Short Answer: No. Transit doesn’t change origin. Long Answer: Under 19 CFR §134.1(a), origin requires substantial transformation. Simply routing through Antwerp doesn’t alter origin.) Warning: Transshipment to evade tariffs is penalized with duties up to 40%. Are synthetic diamonds also exempt? No, the exemption only applies to natural diamonds, as is defined by their HS code. When is a diamond considered Belgian/EU origin? Short Answer: If the transformation from rough to polished (polishing) was done in Belgium (or another EU-country). Long Answer: A rough diamond mined in Botswana or Angola, polished in Antwerp, becomes EU origin. Under Anheuser-Busch Brewing Ass’n v. United States (1908), a new and different article with a distinct character or use emerges after polishing. What if a diamond is only sawn or bruted abroad before polishing in Belgium? Short Answer: If imported as rough and polished in Belgium, origin = EU. Long Answer: HS 7102.31 classifies rough diamonds (sawn, cleaved, bruted). Only polishing (7102.39) changes the origin. Confirmed by a 2019 CBP ruling: stones blocked in China, polished in India, became Indian origin. Is the 10% blanket tariff still in place? Short Answer: No. Since July 24th 2026, AWDC is pleased to announce that the 0% tariff for natural diamonds polished in the EU is back in place. What is the penalty if US Customs disagrees with the declared origin? - 24 September 2025 Short Answer: You could face a penatly of upto 40% of the shipment value, plus delays. Long Answer: Mis-declaration risks penalties, audits, and seizure if intentional. How is the Tariff applied if I import rough from India and polish the diamond in Antwerp? - 24 July 2026 Short Answer: Import rough from India, finish polishing in Belgium → origin EU 0% tariff rate. Long Answer: Strategy: Brute/block in India, ship to Antwerp for polishing. Final origin of polished = EU. Is recutting considered a change of origin? Short answer: No. Long answer: Diamonds that are polished abroad and are recut in Belgium are NOT considered Belgian. Those diamonds have the origin of the country where they were (first) polished. Diamonds that are rough (rough form till the process of bruting) that enter Belgium (as rough), and are polished here, are considered Belgian diamonds. Recutting = not a new product, as it was already a “polished” stone. If you are not sure, you can email pictures of your diamonds to: Nele Stessens (FOD Economie) [email protected] or [email protected] and they will try to review this for you based on these images. If you’re importing these diamonds to Belgium and have questions, you, as an importer, are entitled to inspect your shipment in advance. To avoid potential problems, we advise you strongly to make use of this possibility. You only need to inform Diamond Office before the clearance of your goods. Why is this important? Because you may not always 100% aware of the goods that are sent to you. However, when the contents of your shipment and the accompanying documents (invoice) do not match, you could face delays, fines or even confiscation of the goods. When can you claim Belgian-origin? You can only claim Belgian or EU-origin when the transformation from rough to polished took place in Belgium (or another EU country). The diamonds must have been polished in Belgium to qualify as Belgian. For example, A rough diamond mined in Botswana or Angola, but polished in Antwerp, becomes EU origin. When can you NOT claim Belgian-origin? Recutting: Re-polishing or recutting an already polished diamond does not change its country of origin. Grandfathering: The grandfathering system identifies goods; it does not define their origin. Click here to find more information on grandfathering. Transshipping: Shipping or routing diamonds through Antwerp does not alter their origin. (This may result in a 40% evasion duty, imposed by the U.S. customs authorities). General Tariff Rules and Explanations What are ‘import tariffs’? Import tariffs, also known as import duties or customs duties, are taxes imposed by a government on imported goods. They are typically calculated as a percentage of the product's value and can vary depending on the type of product and its country of origin. The import duties are paid by the importer and may be fully or partially passed on to the end customer. How do you determine the origin of diamonds? - UPDATED July 24, 2026 Global trade rules determine the origin of diamonds as follows: Rough diamonds: The country where the stone was mined is considered its country of origin. Practical: A rough diamond from a mine in Angola is therefore classified as an Angolese product and has been subject to President Trump's 12.5% import tariffs on Angolese goods. Practical: A rough diamond mined in Angola, purchased by a Belgian company, and subsequently sent to the US—for example, for a DOR Report by GIA—falls under these import tariffs, meaning the recipient will have to pay a 12.5% import duty, as the diamond remains in its rough form (Origin: Angola). Polished diamonds: The country where the diamond was processed/polished (WTO rules on “substantial transformation*”) is considered its country of origin. Practical: A rough diamond from a mine in Canada that was sent to India for manufacturing is now considered an Indian diamond. If this diamond is then sent to the US, the recipient will have to pay a 10% import duty. Practical: A rough diamond from a mine in Canada, polished in Canada, remains a Canadian diamond. If this diamond is then sent to the US, the import duty is 0% as the diamond is USMCA-compliant. *In WTO rules, "substantial transformation" determines a product's origin when it's not wholly obtained in a single country, meaning the country where the last significant manufacturing or processing occurred, giving the product its essential character, is considered the origin.
