The country where the metal was melted and poured (steel) or smelted and cast (aluminum and copper) controls the rate, and qualifying U.S.-origin metal can unlock a reduced 10 percent rate when it meets the 85 percent weight threshold.<\/li>\n<li>Redstone Manufacturing acts as importer of record, handles HTS classification and duty payment, and manages tariff changes on modified Delivered Duty Paid (DDP) terms so buyers receive a single landed price without dealing with customs paperwork.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/redstonemanufacturing.com\/contact-us\/#quote-form\" class=\"solid-button\" target=\"_blank\">Get a Landed-Cost Quote From Redstone Manufacturing<\/a><\/p>\n<h2>How Section 232 Tariffs Are Calculated<\/h2>\n<p><a href=\"https:\/\/whitehouse.gov\/presidential-actions\/2026\/04\/strengthening-actions-taken-to-adjust-imports-of-aluminum-steel-and-copper-into-the-united-states\" target=\"_blank\" rel=\"noindex nofollow\">Section 232 duty equals the full customs value of the imported article multiplied by the applicable Section 232 ad valorem rate<\/a>. For example, a <a href=\"https:\/\/kpmg.com\/us\/en\/taxnewsflash\/news\/2026\/04\/united-states-new-rules-calculating-section-232-tariffs-steel-aluminum-copper.html\" target=\"_blank\" rel=\"noindex nofollow\">steel bracket with a customs value of $10,000 subject to a 50 percent rate carries a Section 232 duty of $5,000<\/a>.<sup data-disclaimer-id=\"49\" data-disclaimer-index=\"1\">1<\/sup> That $5,000 sits on top of any ordinary Column 1 duty and any applicable Section 301 duty.<\/p>\n<h2>The Formula, Step By Step<\/h2>\n<p>The calculation runs in four steps. Each step is a decision point, and a wrong assumption at any step produces a wrong number.<\/p>\n<p><strong>Step 1: Identify The Harmonized Tariff Schedule Code<\/strong>. The <a href=\"https:\/\/www.usitc.gov\/harmonized_tariff_information\/frequently_asked_questions\" target=\"_blank\" rel=\"noindex nofollow\">Harmonized Tariff Schedule of the United States (HTSUS)<\/a> is the hierarchical classification system, based on the international Harmonized System, that assigns imported goods 8-digit rate lines and 10-digit statistical reporting codes. That code sets the ordinary duty rate and shows whether the good appears in one of the Section 232 annexes. The <a href=\"https:\/\/globaltradealert.org\/blog\/s232-metals-restructuring-april-2026\" target=\"_blank\" rel=\"noindex nofollow\">April 2026 annexes reorganized covered products into four tiers<\/a>: Annex I-A (core metals and close derivatives, 50 percent rate), Annex I-B (downstream manufactured articles, 25 percent rate), Annex III (certain metal-intensive industrial equipment, 15 percent floor through December 31, 2027), and Annex II (products removed from Section 232 scope).<\/p>\n<p><strong>Step 2: Establish The Customs Value<\/strong>. The <a href=\"https:\/\/uscode.house.gov\/view.xhtml;jsessionid=A96DA8AAC51D2EAA82FB59DA3FC7541B?edition=prelim&amp;f=&amp;fq=&amp;hl=false&amp;num=0&amp;path=&amp;req=granuleid%3AUSC-prelim-title19-section1401a\" target=\"_blank\" rel=\"noindex nofollow\">customs value<\/a> of imported merchandise is usually the transaction value. That is the price actually paid or payable for the merchandise when sold for exportation to the United States, plus specified statutory additions. This figure is the starting point for the Section 232 calculation.<\/p>\n<p>The critical change for buyers came on April 6, 2026. <a href=\"https:\/\/whitehouse.gov\/presidential-actions\/2026\/04\/strengthening-actions-taken-to-adjust-imports-of-aluminum-steel-and-copper-into-the-united-states\" target=\"_blank\" rel=\"noindex nofollow\">Section 232 duties now apply to the full customs value of the imported product, regardless of metal content<\/a>. Before that date, <a href=\"https:\/\/bdo.com\/insights\/tax\/section-232-metals-tariffs-expanded-and-recalibrated-what-importers-need-to-know\" target=\"_blank\" rel=\"noindex nofollow\">U.S. Customs and Border Protection (CBP) often calculated duty only on the metal-content value<\/a>. A <a href=\"https:\/\/globaltradealert.org\/blog\/s232-metals-restructuring-april-2026\" target=\"_blank\" rel=\"noindex nofollow\">part that is 20 percent steel by value now pays 25 percent on 100 percent of its customs value, not 25 percent on 20 percent of it<\/a>. <a href=\"https:\/\/globaltradealert.org\/blog\/s232-metals-restructuring-april-2026\" target=\"_blank\" rel=\"noindex nofollow\">Analysis puts the breakeven metal-content point at around 50 percent for Annex I-B products<\/a>. Below that level, the shift to full-value assessment raises the effective tariff even though the nominal rate fell.<\/p>\n<p><strong>Step 3: Confirm Whether The Good Is In Scope<\/strong>. Not every steel or aluminum part is automatically covered. <a href=\"https:\/\/content.govdelivery.com\/accounts\/USDHSCBP\/bulletins\/4117593\" target=\"_blank\" rel=\"noindex nofollow\">For goods classified outside HTSUS Chapters 72, 73, 74, and 76, CBP confirms a 15 percent weight threshold<\/a>. If the aggregate weight of the applicable metal is less than 15 percent of the total weight of the imported article, the good is exempt from Section 232 duties. Importers claiming this exemption must document it with bills of materials and product specification data if CBP asks.<\/p>\n<p><strong>Step 4: Apply The Section 232 Rate<\/strong>. The rate depends on the annex, the metal origin, and the country of production. <a href=\"https:\/\/whitehouse.gov\/presidential-actions\/2026\/06\/further-adjusting-the-tariff-regimes-for-imports-of-aluminum-steel-and-copper-into-the-united-states\" target=\"_blank\" rel=\"noindex nofollow\">The standard rates under Proclamation 11021 are 50 percent for Annex I-A articles and 25 percent for Annex I-B derivatives<\/a>.<sup data-disclaimer-id=\"49\" data-disclaimer-index=\"1\">1<\/sup> <a href=\"https:\/\/whitehouse.gov\/presidential-actions\/2026\/06\/further-adjusting-the-tariff-regimes-for-imports-of-aluminum-steel-and-copper-into-the-united-states\" target=\"_blank\" rel=\"noindex nofollow\">A reduced 10 percent rate applies to derivative articles made with U.S.-origin metal when that metal accounts for at least 85 percent of the metal weight in the product<\/a>.<sup data-disclaimer-id=\"49\" data-disclaimer-index=\"1\">1<\/sup> The <a href=\"https:\/\/whitehouse.gov\/presidential-actions\/2026\/06\/further-adjusting-the-tariff-regimes-for-imports-of-aluminum-steel-and-copper-into-the-united-states\" target=\"_blank\" rel=\"noindex nofollow\">June 1, 2026 proclamation lowered this threshold from 95 percent<\/a>.<\/p>\n<p>A worked example, labeled illustrative: a <a href=\"https:\/\/globaltradealert.org\/blog\/s232-metals-restructuring-april-2026\" target=\"_blank\" rel=\"noindex nofollow\">steel enclosure bracket classified in Annex I-B with a customs value of $8,000, made with non-U.S. steel, imported from China<\/a>.

It does not follow where the finished part was assembled. This single rule drives many surprises in Section 232 bills.<\/p>\n<p><a href=\"https:\/\/gingercontrol.com\/blog\/does-moving-sourcing-cut-tariff-bill-2026\" target=\"_blank\" rel=\"noindex nofollow\">CBP defines the steel melt-and-pour country as the original location where raw steel is first produced in a steelmaking furnace in liquid state and poured into its first solid shape<\/a>. <a href=\"https:\/\/gingercontrol.com\/blog\/does-moving-sourcing-cut-tariff-bill-2026\" target=\"_blank\" rel=\"noindex nofollow\">For aluminum and copper, the equivalent test is where the metal was smelted and cast<\/a>. <a href=\"https:\/\/gingercontrol.com\/blog\/does-moving-sourcing-cut-tariff-bill-2026\" target=\"_blank\" rel=\"noindex nofollow\">A part assembled in Vietnam from steel melted in China is still a Chinese-steel part for Section 232 purposes<\/a>, even if Vietnam is the country of origin for other trade rules.<\/p>\n<p>This rule can create problems or opportunities. A buyer who assumes a Vietnamese-made steel bracket falls outside Section 232 scope because it was made in Vietnam often pays the wrong amount. The same rule also enables a different structure. A buyer can purchase U.S.-origin steel or aluminum, ship it overseas for casting or fabrication, and bring the finished part back. Because the metal was melted and poured or smelted and cast in the United States, the derivative article can qualify for the reduced 10 percent Section 232 rate instead of the 50 percent or 25 percent standard rate. Redstone has structured programs this way for customers with steel- or aluminum-intensive parts.<\/p>\n<h2>Section 232 Vs. Section 301: Why Both Can Apply<\/h2>\n<p>Knowing that duty follows the metal explains only part of the bill. Section 232 and Section 301 are two different statutes with two different triggers, and both can apply to the same import.<\/p>\n<p>Section 301 of the Trade Act of 1974 targets a country. It applies because of where the part was made, and the China duties are the most familiar example. <a href=\"https:\/\/cov.com\/en\/news-and-insights\/insights\/2026\/08\/current-and-forthcoming-section-301-trade-actions-by-the-trump-administration\" target=\"_blank\" rel=\"noindex nofollow\">Section 301 tariffs on China currently range from 7.5 percent to 100 percent depending on the product list<\/a>.<sup data-disclaimer-id=\"49\" data-disclaimer-index=\"1\">1<\/sup> These tariffs respond to trade practices, not to the material in the part.<\/p>\n<p>Section 232 targets a material on national security grounds, primarily steel and aluminum. Its derivative product lists pull ordinary custom parts into scope even when buyers do not think of their parts as metal products. <a href=\"https:\/\/cov.com\/en\/news-and-insights\/insights\/2026\/04\/current-and-forthcoming-section-232-actions-by-the-trump-administration\" target=\"_blank\" rel=\"noindex nofollow\">As confirmed in April 2026, all Section 232 tariffs continue to apply on top of tariffs in force on imports from China under Section 301<\/a>. A single import can face both duties at once.<\/p>\n<p>Consider a layered example. A steel bracket made in China can carry a 25 percent Section 232 duty because it is a steel derivative. It can also carry a Section 301 duty because it is Chinese-origin. Both sit on top of the ordinary Column 1 duty rate for its HTS code. A buyer who treats the Section 232 number as a replacement for the Section 301 number understates landed cost.<\/p>\n<h2>Which Goods And HTS Codes Fall Under Section 232 Metals Tariffs<\/h2>\n<p>The base categories are steel, aluminum, and copper. The April 2026 proclamation addressed aluminum, steel, and copper articles and derivatives. <a href=\"https:\/\/cov.com\/en\/news-and-insights\/insights\/2026\/04\/current-and-forthcoming-section-232-actions-by-the-trump-administration\" target=\"_blank\" rel=\"noindex nofollow\">Separate Section 232 actions<\/a> cover autos and auto parts, medium and heavy trucks, timber and lumber, semiconductors, and pharmaceuticals, each with its own proclamation and rate structure.<\/p>\n<p>For metal articles, the annex structure of the April 2026 proclamation controls scope. <a href=\"https:\/\/whitehouse.gov\/wp-content\/uploads\/2026\/04\/ANNEXES-I-A-I-B-II-III-IV.pdf\" target=\"_blank\" rel=\"noindex nofollow\">Annex I-A covers core steel mill products under HTSUS headings 7206 through 7229<\/a> and <a href=\"https:\/\/whitehouse.gov\/wp-content\/uploads\/2026\/04\/ANNEXES-I-A-I-B-II-III-IV.pdf\" target=\"_blank\" rel=\"noindex nofollow\">selected downstream steel articles including pipe fittings (heading 7307), structural articles (heading 7308), containers and tanks (headings 7309 and 7310), screws and bolts (heading 7318), and cast and forged articles (headings 7325 and 7326)<\/a>.

A buyer who makes enclosures, brackets, frames, or housings may not think of their product as a steel or aluminum article. If the HTS code appears in Annex I-A or Annex I-B, the part is in scope. Scope changes on a rolling basis. <a href=\"https:\/\/icpainc.org\/section-232-tracker\" target=\"_blank\" rel=\"noindex nofollow\">The U.S. Department of Commerce and the U.S. Trade Representative can add derivative products jointly at any time by Federal Register notice<\/a>. Every tariff analysis needs a clear as-of date.<\/p>\n<h2>Which Products Qualify For Section 232 Exemptions Or Reduced Rates<\/h2>\n<p>Exemptions exist, but they are narrow and depend on the specific part, metal, and origin.<\/p>\n<p>The broadest exemption is the 15 percent metal-content threshold described earlier. For goods classified outside HTSUS Chapters 72, 73, 74, and 76, if the aggregate weight of the applicable metal is less than 15 percent of the total weight of the imported article, the good is exempt. <a href=\"https:\/\/whitehouse.gov\/wp-content\/uploads\/2026\/04\/ANNEXES-I-A-I-B-II-III-IV.pdf\" target=\"_blank\" rel=\"noindex nofollow\">This exemption does not apply to goods classified within HTSUS Chapters 72, 73, 74, and 76<\/a>, and it requires documentation.<\/p>\n<p>Other exemptions include <a href=\"https:\/\/content.govdelivery.com\/accounts\/USDHSCBP\/bulletins\/4117593\" target=\"_blank\" rel=\"noindex nofollow\">motorcycle parts classified in HTSUS Chapters 84, 85, and 87 imported for the sole purpose of manufacturing motorcycles in the United States<\/a>, <a href=\"https:\/\/whitehouse.gov\/presidential-actions\/2026\/04\/strengthening-actions-taken-to-adjust-imports-of-aluminum-steel-and-copper-into-the-united-states\" target=\"_blank\" rel=\"noindex nofollow\">civil aircraft parts covered by the World Trade Organization (WTO) Agreement on Trade in Civil Aircraft and manufactured in the United Kingdom, European Union, South Korea, or Japan<\/a>, and <a href=\"https:\/\/globaltradealert.org\/blog\/s232-metals-restructuring-april-2026\" target=\"_blank\" rel=\"noindex nofollow\">products listed in Annex II, which were removed from Section 232 scope under the April 2026 proclamation<\/a>. <a href=\"https:\/\/chrobinson.com\/en-us\/resources\/blog\/section-232-changes-for-aluminum-copper-steel\" target=\"_blank\" rel=\"noindex nofollow\">Annex II removals include consumer goods, chemicals, and commodities where metal content is incidental to packaging rather than structural<\/a>.<\/p>\n<p><a href=\"https:\/\/whitehouse.gov\/presidential-actions\/2026\/06\/further-adjusting-the-tariff-regimes-for-imports-of-aluminum-steel-and-copper-into-the-united-states\" target=\"_blank\" rel=\"noindex nofollow\">Products made with U.S.-origin metal receive a reduced 10 percent rate instead of the standard 25 or 50 percent rate when U.S.-origin metal accounts for at least 85 percent of the metal weight in the product<\/a>.

Trade Agreement Partners include Canada, the European Union, Japan, Mexico, South Korea, the United Kingdom, and other partners with a final Agreement on Reciprocal Trade.

That situation involves a classification dispute, not a drawback claim. For entries made on or after December 18, 2004, the window for filing a protest with CBP is generally 180 days from the date of liquidation of the entry.<\/p>\n<h2>When The Calculator&#8217;s Number Is Wrong<\/h2>\n<p>A Section 232 tariff calculator produces a number, but it does not confirm whether the inputs are correct. Several common failure modes can mislead buyers.<\/p>\n<ul>\n<li><strong>It Assumes The Part Is In Scope When It May Not Be.<\/strong> If the part&#8217;s HTS code does not appear in Annex I-A or Annex I-B, or if the metal content falls below the 15 percent weight threshold for goods outside Chapters 72 through 74 and 76, the part may fall outside Section 232. A calculator that applies a rate without confirming scope produces a false positive.<\/li>\n<li><strong>It Assumes The Metal Origin Matches The Part Origin.<\/strong> A calculator that takes \u201cmade in Vietnam\u201d as the input and applies no Section 232 duty because Vietnam is not China ignores the melt-and-pour rule. If the steel was melted in China, the Section 232 duty applies regardless of where the part was fabricated.<\/li>\n<li><strong>It Treats Section 232 As A Replacement For Section 301.<\/strong> The two duties stack. A calculator that shows only the Section 232 number shows an incomplete landed cost for Chinese-origin goods.<\/li>\n<li><strong>It Uses The Old Metal-Content Basis Instead Of Full Product Value.<\/strong> <a href=\"https:\/\/bdo.com\/insights\/tax\/section-232-metals-tariffs-expanded-and-recalibrated-what-importers-need-to-know\" target=\"_blank\" rel=\"noindex nofollow\">CBP&#8217;s Base Metals Center of Excellence was rate-advancing entries on a metal-content basis in late 2025<\/a>, and some tools were built around that practice. Effective April 6, 2026, the basis is full customs value. A calculator that has not been updated produces a systematically low number for any part with less than 100 percent metal content.<\/li>\n<\/ul>\n<h2>How Redstone Manufacturing Takes The Calculation Off Your Desk<\/h2>\n<p>Most buyers in this market are not importers. They have a part, a supplier quote, and a growing list of tariff questions they do not have the background to answer. Redstone Manufacturing focuses on solving that problem.<\/p>\n<p>Redstone acts as importer of record on modified Delivered Duty Paid (DDP) terms. The importer of record is the party legally responsible for the customs entry, including classifying the goods, filing the paperwork, and paying duties and tariffs. That responsibility normally falls on the buyer. Redstone takes it instead.<\/p>\n<p>Modified DDP means the seller moves the goods all the way to the buyer&#8217;s dock with duties paid. Redstone&#8217;s version quotes freight separately, prepaid and added to the invoice, rather than burying it in the part price. The result is one clear landed unit price. The customer does not file customs entries, speak to a customs broker, or manage tariff questions.<\/p>\n<p>Because Redstone classifies parts by end use, the duty rate on the quote reflects how the part will actually be used. Duties are included at rates in effect on the quote date and adjusted at shipment if they change. Redstone tracks rate movement between quote and shipment and updates invoices accordingly. When a proclamation changes the calculation basis or adds a derivative product to scope, Redstone absorbs the classification and rate work.<\/p>\n<p>Because the contract sits with a U.S. company, repair, replacement, or refund responsibility stays domestic. If something goes wrong, the buyer has recourse in the United States. Payment follows the same buyer-friendly logic. Nothing is owed until samples are approved and in-spec production parts ship, then payment terms are Net 30 or Net 60 from ship date.<\/p>\n<p>If tariffs or conditions change, Redstone can move a program between its facilities in China, India, Taiwan, Vietnam, and Mexico without the customer requalifying a supplier. Redstone also uses the material-origin rule proactively by buying U.S.-origin metal, shipping it to an overseas facility for casting, and bringing the finished part back at the reduced 10 percent rate instead of the standard 25 or 50 percent rate.<\/p>\n<p>Redstone operates its own 5-axis computer numerical control (CNC) machining facility in Seattle. A casting can be produced at an overseas facility and machined domestically, with one company accountable for both ends. Many machine shops avoid castings and ask the customer to source them independently. Redstone manages both casting and machining as a single program.<\/p>\n<p><a href=\"https:\/\/redstonemanufacturing.com\/contact-us\/#quote-form\" class=\"solid-button\" target=\"_blank\">Get Your Landed Cost and Tariff Exposure Reviewed<\/a><\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p>Here are concise answers to the questions buyers ask most often about Section 232 calculations.<\/p>\n<h3>How Are Section 232 Tariffs Calculated?<\/h3>\n<p>Multiply the full customs value of the imported article by the applicable Section 232 rate. The rate depends on the product&#8217;s annex classification and any qualifying metal-origin rules. See \u201cThe Formula, Step By Step\u201d above for the full breakdown.<\/p>\n<h3>What Is The Current Section 232 Tariff Rate?<\/h3>\n<p><a href=\"https:\/\/icpainc.org\/section-232-tracker\" target=\"_blank\" rel=\"noindex nofollow\">As of September 2026, the standard rates are 50 percent on core steel, aluminum, and copper articles in Annex I-A and 25 percent on derivative articles in Annex I-B<\/a>.<sup data-disclaimer-id=\"49\" data-disclaimer-index=\"1\">1<\/sup> <a href=\"https:\/\/whitecase.com\/insight-alert\/united-states-modifies-steel-aluminum-and-copper-section-232-tariffs\" target=\"_blank\" rel=\"noindex nofollow\">A 15 percent floor applies to certain metal-intensive industrial and electrical grid equipment in Annex III through December 31, 2027<\/a>.<sup data-disclaimer-id=\"49\" data-disclaimer-index=\"1\">1<\/sup> Some products qualify for reduced rates based on metal origin, such as qualifying U.K.-origin or U.S.-origin metal. Always confirm the current proclamation text before finalizing quotes.<\/p>\n<h3>Which Products Are Exempt From Section 232 Tariffs?<\/h3>\n<p>Key exemptions include the 15 percent metal-content threshold described earlier, certain motorcycle parts used in U.S. motorcycle manufacturing, qualifying civil aircraft parts from specified partners, and products listed in Annex II. Whether a part qualifies depends on its HTS classification, metal content by weight, and metal origin. See \u201cWhich Products Qualify For Section 232 Exemptions Or Reduced Rates\u201d for details.<\/p>\n<h3>Are Section 232 Tariffs Eligible For Refund?<\/h3>\n<p>Most Section 232 duties are not refundable. A narrow manufacturing drawback path exists for specific Annex I-B and Annex III products from Trade Agreement Partners that meet strict metal-origin rules. Misclassification issues are handled through CBP protests, not drawback. See \u201cWhen Section 232 Tariffs Can Be Refunded Or Corrected\u201d above for the full criteria.<\/p>\n<h3>Which HTS Codes Are Affected By Section 232?<\/h3>\n<p>The April 2, 2026 proclamation annexes control scope. Annex I-A covers core steel, aluminum, and copper articles, and Annex I-B covers a wide range of downstream manufactured goods. Commerce and the U.S. Trade Representative can add derivative products by Federal Register notice at any time. Always check the current annex text rather than relying on a static list.<\/p>\n<h3>Does Section 232 Stack With Section 301?<\/h3>\n<p>Yes, in most cases. Section 232 applies based on material, and Section 301 applies based on country. Many imports, such as steel brackets made in China, can incur both duties on top of ordinary Column 1 duty.
