The document usually has a certificate, a tree-planting photo and no declared unit. That is not an answer, and since the EU moved CBAM into its definitive phase it is now an answer that costs your importer real money.<\/p>\n<\/div>\n<p style=\"margin: 0 0 18px;\">This guide gives you the arithmetic instead. We build a cradle-to-gate casting carbon footprint line by line for a ductile iron housing, show which two inputs actually move it, then run the same part in A356 aluminium and get a number that swings 8\u00d7 on a single line of the purchase spec. Every figure below comes from a stated emission factor, so you can swap in your own foundry&#8217;s data.

Under the cut-off method they carry zero burden of their own; under recycled-content accounting they carry part of it. Ask which one was used.<\/li>\n<li style=\"margin: 0 0 8px;\"><strong style=\"color: #273171;\">Direct vs indirect.<\/strong> Direct means fuel burned in the process. Indirect means the emissions behind the electricity you bought. For steel and aluminium under CBAM, only direct counts \u2014 which surprises most people.<\/li>\n<\/ul>\n<p style=\"margin: 0 0 18px;\">Get those three in writing before you compare anything: a casting carbon footprint is only comparable when the unit, the allocation rule and the direct\/indirect split all match. A &#8220;2.0 t CO<sub>2<\/sub>e per tonne&#8221; figure is meaningless until you know it is 2.0 per shipped tonne, cut-off basis, direct-only, for a specific part number.<\/p>\n<h2 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 25px; font-weight: 600; line-height: 1.3; margin: 34px 0 14px; padding: 4px 0 4px 30px; background: linear-gradient(to right, #ff512f 0px, #dd2476 5px, transparent 5px);\">Four Lines That Move Your Casting Carbon Footprint<\/h2>\n<p style=\"margin: 0 0 18px;\">For induction-melted ferrous castings the whole calculation collapses into four lines plus a mass balance that most people get wrong. Get the mass balance right and your casting carbon footprint stops moving every time somebody re-counts it. Take a ductile iron pump housing: <strong style=\"color: #273171;\">18 kg finished, 55% yield<\/strong>, 12,000 per year, melted in a medium-frequency induction furnace.<\/p>\n<p style=\"margin: 0 0 18px;\">Here is the mass balance that trips everyone up. Per tonne of <em>shipped<\/em> castings at 55% yield, the foundry pours 1 \/ 0.55 = <strong style=\"color: #273171;\">1.818 t of metal<\/strong>. Of that, 1.0 t leaves as castings and 0.818 t comes back as internal returns and is remelted. So the purchased metal per shipped tonne is <strong style=\"color: #273171;\">1.0 t \u2014 always<\/strong>, whatever the yield. Yield does not change how much metal you buy. It changes how much metal you melt.<\/p>\n<table style=\"width: 100%; border-collapse: collapse; margin: 18px 0 24px; font-size: 15px; color: #333333;\">\n<thead>\n<tr>\n<th style=\"background: #273171; color: #ffffff; padding: 12px 14px; text-align: left; font-weight: 600; border: 1px solid #273171;\">Input line<\/th>\n<th style=\"background: #273171; color: #ffffff; padding: 12px 14px; text-align: left; font-weight: 600; border: 1px solid #273171;\">Basis<\/th>\n<th style=\"background: #273171; color: #ffffff; padding: 12px 14px; text-align: left; font-weight: 600; border: 1px solid #273171;\">Emission factor<\/th>\n<th style=\"background: #273171; color: #ffffff; padding: 12px 14px; text-align: left; font-weight: 600; border: 1px solid #273171;\">t CO<sub>2<\/sub>e \/ t shipped<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">Pig iron<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.550 t purchased<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">1.80 t CO<sub>2<\/sub>e \/ t<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.990<\/td>\n<\/tr>\n<tr style=\"background: #F5F5F5;\">\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">Purchased steel scrap<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.450 t purchased<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.35 t CO<sub>2<\/sub>e \/ t<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.158<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">Internal returns<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.818 t remelted<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.00 (cut-off)<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.000<\/td>\n<\/tr>\n<tr style=\"background: #F5F5F5;\">\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">Ferrosilicon + carburiser<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">1.8% of metal melted<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">4.0 \/ 3.0 t CO<sub>2<\/sub>e \/ t<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.120<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">Melting electricity<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">580 kWh\/t \u00d7 1.818 t = 1,055 kWh<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.570 kg CO<sub>2<\/sub>e \/ kWh<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.601<\/td>\n<\/tr>\n<tr style=\"background: #F5F5F5;\">\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">Moulding, coring, fettling<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">per tonne melted<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.090 t CO<sub>2<\/sub>e \/ t<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">0.164<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\"><strong>Total cradle-to-gate<\/strong><\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\"><strong>per tonne shipped<\/strong><\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\">\u2014<\/td>\n<td style=\"border: 1px solid #E5E5E5; padding: 10px 14px;\"><strong>2.032<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin: 0 0 18px;\">That gives <strong style=\"color: #273171;\">2.03 t CO<sub>2<\/sub>e per tonne of shipped castings<\/strong>, or <strong style=\"color: #273171;\">36.6 kg CO<sub>2<\/sub>e per 18 kg housing<\/strong>.

A 100% scrap charge in ductile iron drags in tramp elements \u2014 copper, chromium, tin, lead \u2014 that push pearlite and carbides where you wanted ferrite. Most production foundries land somewhere between 20% and 60% pig iron and buy the rest as certified low-residual scrap. Knowing that range is what lets you sanity-check a supplier&#8217;s casting carbon footprint claim.<\/p>\n<h2 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 25px; font-weight: 600; line-height: 1.3; margin: 34px 0 14px; padding: 4px 0 4px 30px; background: linear-gradient(to right, #ff512f 0px, #dd2476 5px, transparent 5px);\">Same Housing in Aluminium: One Line in the Spec, an 8\u00d7 Swing<\/h2>\n<p style=\"margin: 0 0 18px;\">Redesign the housing in A356-T6 and it comes out at about 6.8 kg. Yield on a permanent-mould or low-pressure aluminium casting runs near 50%, so the foundry melts 2.0 t per shipped tonne and buys 1.0 t of ingot.

Meanwhile 7325 is exactly the heading that takes the hardest hit on US Section 232 derivative duties. One classification decision sets your duty rate and your casting carbon footprint bill in opposite directions depending on destination \u2014 which is why the <a style=\"color: #086ad4; text-decoration: none;\" href=\"https:\/\/chinametalfoundry.com\/pl\/blog\/casting-import-duty-and-hs-codes\/\" target=\"_blank\">HS code and import duty<\/a> walkthrough insists you settle the code before you model any landed cost.<\/p>\n<p style=\"margin: 0 0 18px;\">Two more rules that matter commercially. First, there is a <strong style=\"color: #273171;\">50 tonne de minimis<\/strong>: below 50 t of CBAM goods per legal entity per calendar year there is no obligation, and the threshold is cumulative across all covered goods, not per shipment. Second, non-preferential origin still governs \u2014 a casting poured in one country and machined in another keeps the origin the pouring gave it if that operation gave it its essential character. Facing a flange does not change origin.<\/p>\n<p style=\"margin: 0 0 18px;\">The aluminium list is published heading by heading; the UK government&#8217;s <a style=\"color: #086ad4; text-decoration: none;\" href=\"https:\/\/www.gov.uk\/government\/publications\/check-which-goods-are-in-scope-of-carbon-border-adjustment-mechanism-cbam\/goods-within-the-aluminium-sector\" target=\"_blank\" rel=\"noopener\">CBAM goods-in-scope list<\/a> mirrors the EU Annex I codes and is the quickest place to check a specific one.

Indirect emissions from purchased electricity are excluded for these two sectors, although they are included for cement and fertilisers. That has an awkward consequence: the number your foundry can measure most cheaply \u2014 its kWh meter \u2014 is the number CBAM does not want. What it wants is the direct emissions embedded in the metal that went into the furnace, supported by a verifier&#8217;s report covering the right period.<\/p>\n<p style=\"margin: 0 0 18px;\">If you cannot produce verified actuals, your declarant falls back to published default values, and those are deliberately punitive. Defaults are set conservatively and carry a mark-up that steps up each year: +10% for 2026, +20% for 2027, +30% from 2028.

But an importer facing a charge they cannot control will come back to you at the next price review, which is why the number belongs in your quote rather than in their compliance file.<\/p>\n<h3 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 20px; font-weight: 600; line-height: 1.4; margin: 22px 0 8px;\">Do castings shipped to the US face anything similar?<\/h3>\n<p style=\"margin: 0 0 18px;\">Not a carbon mechanism.
