In 2025 EU-27 imports from outside the EU amounted to 3,112 t (EUR 40.9 million) and exports to 2,668 t (EUR 56.2 million); the mass balance was −444 t (import surplus). Intra-EU arrivals (reported by EU countries) – 4,545 t. Main non-EU suppliers: China (78.0%), India (9.3%) and United States (4.2%). Main non-EU customers: United States (32.1%), China (20.8%) and Saudi Arabia (7.2%). Between 2015 and 2025 import mass changed by +61.8% and export mass by −57.9%. EU-27 sold production according to PRODCOM (code 24.44.26.30, shared with classes: “Straight copper tubes”, “Copper tubes in coils”, “Brass tubes”, “Bronze and other copper-alloy tubes”) was 267 thousand t in 2025 (EUR 2.62 billion; a Eurostat estimate). EU-27 apparent consumption within the scope of the PRODCOM code (sold production + non-EU imports − non-EU exports; excluding production for own use): 257 thousand t.

## What you should know about this data

- The class covers CN code 7411 22 00 (CN 2026); PRODCOM code 24.44.26.30 also covers classes: “Straight copper tubes”, “Copper tubes in coils”, “Brass tubes”, “Bronze and other copper-alloy tubes” – production refers to the whole group.
- Class codes unchanged in 2005–2025 (Eurostat CN8 predecessor–successor table) – comparable series.
- PRODCOM (sold production, 24.44.26.30): EU-27 quantity in 2010, 2021–2025 is a Eurostat estimate (E); EU-27 quantity in 2011–2019 rounded by Eurostat (R; value ± rounding base); country data with a quantity in tonnes labelled KG (K; identified by unit value, taken as tonnes): FI 2024 – the EU-27 aggregate for those years may understate it (cannot be resolved from public data); country data with an unreliable unit value (X; quantity or value without a figure): IT 2019; years without EU-27 quantity: 2005 (confidentiality, no code or an unreliable value – a gap, not zero; the series does not link PRODCOM list changes before 2024 – years before the code was introduced have no figure); quantity confidential (C) in 2025 in 7 countries (AT, CZ, FR, GR, IE, LV, NL) – confidential values are not filled in; apparent consumption is based on sold production – excluding output used within the producing plant (e.g. wire rod drawn into wire), which understates the result for semi-finished products.
- Unit value (EUR/t) is the ratio of trade value to mass – it depends on the product mix, metal content and partner structure; it is not a market price.
- Year 2026 – monthly data: extra-EU January–August, intra-EU January–July (incomplete, provisional year).

## EU-27 trade, 2005–2025

EU-27 imports and exports – with non-EU countries or within the EU (arrivals reported by EU countries and their dispatches to other EU countries) – in tonnes, euro or as unit value; the current year – monthly data (incomplete year).

## Product chain

Chain of the class “Cupro-nickel and nickel silver tubes”: preceding classes – –; following classes – –.

- **Feedstock**: Unwrought copper (feedstock) (CN 7403)
- **Class**: [Cupro-nickel and nickel silver tubes](https://www.ai-waw.com/en/products/cuni-tube) (CN 7411 22 00)
- **Scrap**: copper scrap (CN 7404)

The scheme orders the classes of the dictionary by processing stage (family rules in the portal code: same material, a derived product after the non-derived one; links named explicitly – e.g. cans from can stock, die castings from casting alloys, coated steel from galvanizing alloys); an arrow does not mean deliveries between specific plants. Feed and scrap – CN headings of the metal, not dictionary classes.

## Method note

- **Entry only from a primary document** – A class is assigned to a plant only when a primary document names it – a product data sheet, an annual report, a register or a company page describing the product – with the document page and a reliability class (A, B or C). Press and company directories without a company document are not a basis for an entry.
- **Assignment from a location document** – When a company document describes the product and only a location page points to the plant, the assignment of the product to the plant is an inference – the source then has class C and the entry awaits confirmation by a plant document.
- **“Full range” is not an entry** – A general claim (“full range of copper products”) without the class, dimensions or alloys does not create an entry. A plant without an entry may make the class – the register does not know.
- **Capacity only from a document** – Class capacity (kt) – only when a document states it; no estimates and no split of a whole plant’s capacity into classes. The sum covers only plants with a stated capacity and is a lower bound – always given with the number of plants it covers.
- **Entry status** – Produced, planned production (investment announced in a document), production ended. A closed plant – production ended. Key figures – “produced” only.
- **Ownership control** – The entity controlling the plant and its country – as in Ownership control (GLEIF Level 2, GLEIF exceptions, groups from company documents). The non-EU share is computed only among producers located in the EU-27 with an established controller (as the default area of Ownership control); a plant outside the EU – e.g. in Türkiye, the United Kingdom, Switzerland or Serbia – is out of scope of the indicator, although it counts among plants and countries.
- **Trade and production** – Eurostat Comext: EU-27 extra-EU and intra-EU trade (arrivals reported by EU countries), CN codes of the class (sum of the codes), tonnes and euro, 2005–2025 plus the current incomplete year (hollow marker, no line); sold production – PRODCOM (a code may cover several classes); apparent consumption = production + extra-EU imports − extra-EU exports within the PRODCOM code scope. A CN code may cover products of other classes (e.g. rods and sections in one code) – trade describes CN codes, not the plants of the register.
- **Metals kept apart** – Each class belongs to one metal (aluminium, copper, zinc). Each metal has its own page; the metals share a family layout – five semi-finished product families (wire rod and wire; bars and sections; plate, sheet and strip; foil; tubes), families outside semi-finished products (unwrought alloys – feedstock, powders and dust, chemical compounds, anodes and other articles – currently zinc only) and derived products; split by material within a family. A family without classes of a metal shows “–” with a description in the comparison table. Header figures and trade totals are given separately for each metal – tonnes of different metals are never added up. Derived products (e.g. winding wire, structures, cans, stranded wire, zinc-coated steel, die castings) are marked and are not semi-finished products; tonnes of coated steel are the mass of the product, not of zinc. A class outside the metal trade total (coated steel, zinc oxide, die castings without a CN code) carries a note with the reason.
- **Counterpart in the other metal** – A copper ↔ aluminium substitution pair (e.g. wire, coiled tubes, strip, stranded wire) comes from the dictionary field or from the portal map of pairs. The comparison shows the figures of both classes side by side, without a total, and the application sentence has no figures; a pair does not mean interchangeability in every application.
- **Links by metal** – Copper classes have a form in the R02 forecast and the EU copper flow analysis; aluminium classes – the EU aluminium flow analysis and the country analyses; zinc classes – the EU zinc flow analysis and the country analysis for Poland (the R01 and R02 forecasts cover copper only). An analysis link given with the class takes precedence.
- **Dataset scope** – The dataset covers copper and aluminium semi-finished products and their alloys, and zinc products (titanium-zinc sheet, unwrought alloys, powders and dust, anodes, derived products) at plants of the Companies register. Counts of plants, countries and groups and the capacity sum are a lower bound of the market – they grow with further documents.
