# My fastener plant buys wire rod and the supplier sends no actual emissions data under the Carbon Border Adjustment Mechanism (CBAM): which default value applies if the rod's country of production is known, and if it is not?

Canonical: https://senseible.earth/answers/cbam-wire-rod-default-known-origin-or-unknown-origin

If the rod's country of production is known, the Combined Nomenclature (CN) 7213 value for that country applies, such as 4.270 for India or 2.310 for Türkiye. If no country can be identified, Annex IV applies: 8.230 tonnes of carbon dioxide equivalent (CO2e) per tonne, before the mark-up.

## The rule

- Article 1(2) of European Union (EU) Implementing Regulation 2025/2621: where a complex good uses actual values and its precursors use default values, the Annex I values apply to those precursors.
- Article 1(5): by way of derogation, where a country of production cannot be identified for a precursor, the Annex IV values apply.
- Guidance No. 3 puts it the same way. The linked page on suppliers without a verification report covers the rule in full.

## Wire rod, CN 7213, tonnes of CO2e per tonne

The code is bars and rods of iron or non-alloy steel, hot-rolled, in irregularly wound coils. The file shows direct emissions only.

- Annex IV, country unknown: 8.230
- Indonesia 8.230, Kazakhstan 5.180
- India 4.270, South Africa 4.030
- Other countries and territories 3.996
- China 3.169
- Viet Nam 2.350, Türkiye 2.310, Taiwan 2.298
- South Korea 2.118, Japan 2.100
- Brazil 1.610, United States 1.390

## Why the invoice has to name the mill's country

Our reading: a trader's invoice that shows only the trader's address may leave you unable to say where the rod was made. Ask the trader for the producing mill and its country in writing, and keep it with the purchase record. With it you can use the country row; without it the Annex IV value is what the rule points to.

By default the precursor takes the production year of the complex good, unless evidence shows another period; for a complex good imported in 2026, the 2026 values apply (Guidance No. 3, 4.10.1). Mixing default and actual values is covered on the linked page.

## Better than either default

Ask the mill for its verification report for the production year. A positive verification report covering the production year lets you use the mill's actual figure instead of any default (Guidance No. 2).

## 1 tonne of bolts, rod ratio of 1.15 tonnes of rod per tonne of product (our example), 2026 mark-up

- Rod known to be Indian: 4.270 x 1.10 = 4.697; x 1.15 = 5.402 tonnes of CO2e from the rod
- Rod from a known Turkish mill: 2.310 x 1.10 = 2.541; x 1.15 = 2.922 tonnes
- Rod of unknown origin: 8.230 x 1.10 = 9.053; x 1.15 = 10.411 tonnes
- Unknown against Indian rod: 10.411 minus 5.402 = 5.009 tonnes more per tonne of bolts

The 1.15 ratio is ours, set only to show the arithmetic; use your own rod used divided by product made. The sums cover the rod alone, before your own fuel.

## What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, which is the plant-side data behind an actual figure. It does not set default values, it is not a CBAM verifier and it does not file declarations.
