India’s Steel Pipes and Tubes: The Downstream CBAM Exposure That No One in the Sector Is Talking About
India exports approximately 3.5 to 4.0 million tonnes of steel pipes and tubes to the EU and UK annually — covering everything from seamless pipes for oil and gas (CN 7304), welded structural tubes (CN 7306), and precision tubes for automotive (CN 7307). All are CBAM-covered. The embedded emission travels with the steel feedstock and the welding or forming process. Most downstream pipe and tube producers have not yet built CBAM MRV infrastructure.
Key Takeaways
- The CBAM Regulation (EU 2023/956 as amended by the 2025 Omnibus) covers iron and steel articles in multiple downstream categories beyond primary HRC, CRC, and sections. The CN codes 7304 (seamless tubes and pipes of iron or non-alloy steel), 7305 (other tubes, pipes and hollow profiles of iron or non-alloy steel), 7306 (welded and other tubes of iron or non-alloy steel), and 7307 (tube or pipe fittings, of iron or steel) are all CBAM-covered products that are exported from India to the EU in significant volumes. India is one of the world’s largest exporters of steel pipes and tubes, with primary producers including Welspun Corp, APL Apollo Tubes, Maharashtra Seamless, and ISMT.
- The CBAM calculation for pipes and tubes is methodologically more complex than for primary steel because it requires tracing the embedded emission of the steel feedstock (hot-rolled or cold-drawn strip, seamless tube rounds, or heavy-wall hollow sections) plus the incremental processing emission from the tube-forming, welding, heat treatment, and finishing operations. For a welded structural tube made from HRC strip, the embedded emission is approximately equal to the HRC’s embedded emission (approximately 2.1 to 2.5 tCO₂/t) plus the processing emission from the ERW welding and sizing operations (approximately 0.05 to 0.15 tCO₂/t). Total embedded emission for a typical Indian welded tube is therefore approximately 2.2 to 2.65 tCO₂/t.
- Seamless pipes — the highest-value segment of India’s pipe export portfolio, primarily for oil and gas applications — have a higher embedded emission profile because of the hot-piercing and hot-rolling operations used in seamless manufacturing. A seamless pipe from a billet requires approximately 1.05 to 1.15 tonnes of steel billet input per tonne of pipe, plus the hot-piercing energy consumption of approximately 0.8 to 1.2 GJ per tonne of pipe. Total embedded emission for a typical Indian seamless pipe is approximately 2.5 to 3.2 tCO₂/t depending on billet source and process configuration. At EU ETS €84.20 and a CBAM benchmark of approximately 1.8 tCO₂/t for downstream steel products, the CBAM certificate obligation on a seamless pipe is approximately €59 to 118 per tonne.
- The competitive exposure of India’s pipe and tube sector is amplified by the 50-tonne de minimis threshold introduced by the CBAM Omnibus 2025/2083. Below 50 tonnes per year of imports from a single supplier-exporter pair, no CBAM obligation applies. India’s pipe and tube export structure has many medium-sized producers shipping 200 to 2,000 tonnes per year to individual EU customers — all above the 50-tonne threshold and therefore fully CBAM-liable. The de minimis threshold eliminates CBAM for the smallest artisanal shipments but provides no relief for India’s established pipe and tube exporters.
- Most of India’s independent pipe and tube producers — as distinct from integrated steel companies with tube divisions — have not established CBAM MRV infrastructure. These are typically companies that purchase HRC or seamless tube rounds from Tata Steel, JSW, JSPL, or import billets, and process them into finished tubes for export. The CBAM MRV challenge for these companies is the upstream embedded emission traceability: they must obtain verified emission data from their steel input suppliers for the specific heats of steel used in their tube production, because the default EU values for finished tube embedded emission significantly overstate the actual intensity of tubes made from EAF scrap-route steel.
- The most commercially urgent CBAM action for India’s pipe and tube exporters is to establish the upstream supply chain data linkage — verifying the embedded emission of their HRC, CRC, or billet inputs from Tata Steel, JSW, or JSPL — since this single data point determines approximately 90 percent of their CBAM obligation. A pipe maker whose inputs come from JSW Steel’s Vijayanagar EAF facility (lower embedded emission than BF-BOF) will have a dramatically different CBAM obligation than a pipe maker using Tata Steel Jamshedpur BF-BOF HRC, even if their tube-making process is identical.
India’s steel pipe and tube sector is a highly fragmented industry with approximately 2,000 producers ranging from large listed companies like Welspun Corp (approximately 2.5 MMT capacity, listed BSE) and APL Apollo Tubes (approximately 3.0 MMT capacity, primarily domestic market) to hundreds of small regional producers in clusters at Mandi Gobindgarh (Punjab), Ankleshwar (Gujarat), Khopoli (Maharashtra), and Hyderabad. The export-oriented segment — primarily the large seamless pipe producers for oil and gas, and the welded structural tube producers for the EU construction and automotive market — is where CBAM exposure is concentrated.
The CBAM compliance challenge for pipe and tube exporters has two layers that differ from primary steel producers. The first layer is inherited complexity: pipe and tube producers do not typically measure their own production process emissions with the granularity required for CBAM — they have not needed to, because the steel industry’s compliance focus has been on primary steel producers. The second layer is upstream traceability: the embedded emission of the steel feedstock is the dominant driver of the CBAM obligation, but a pipe producer may purchase HRC from multiple suppliers with different emission profiles, mixed in the same production run. Attributing the correct per-heat emission factor to specific export consignments requires a supply chain data system that most pipe producers do not yet have.
The EAF-scrap advantage for downstream pipe producers
CBAM Obligation Comparison — Indian Welded Tube by Steel Feedstock Source
| Steel Input Source | Production Route | Input Embedded Emission | Tube Processing Addition | Total Tube CBAM | CBAM Cost at €84.20 |
|---|---|---|---|---|---|
| Tata Steel Jamshedpur HRC | BF-BOF | ~2.40 tCO₂/t | +0.10 tCO₂/t | ~2.50 tCO₂/t | ~€59/t (above 1.8 benchmark) |
| JSW Vijayanagar HRC | DRI-EAF (coal-DRI) | ~2.60 tCO₂/t | +0.10 tCO₂/t | ~2.70 tCO₂/t | ~€76/t |
| JSW Vijayanagar HRC (EAF scrap unit) | Scrap-EAF | ~0.55 tCO₂/t | +0.10 tCO₂/t | ~0.65 tCO₂/t | ~€0/t (below 1.8 benchmark) |
| JSPL Angul DRI-EAF (gas-based) | Gas DRI-EAF | ~0.95 tCO₂/t | +0.10 tCO₂/t | ~1.05 tCO₂/t | ~€0/t (below 1.8 benchmark) |
| Imported Chinese HRC | BF-BOF (China mix) | ~2.20 tCO₂/t | +0.10 tCO₂/t | ~2.30 tCO₂/t | ~€42/t (if Chinese default used) |
The Indian pipe producer that switches to JSPL gas-DRI EAF HRC eliminates its CBAM obligation entirely. A welded structural tube producer currently sourcing BF-BOF HRC from Tata Steel Jamshedpur and exporting to the EU faces a CBAM obligation of approximately €59 per tonne of tube. Switching to JSPL Angul gas-DRI EAF HRC — which carries an embedded emission of approximately 0.95 tCO₂/t, below the EU CBAM benchmark of 1.8 tCO₂/t — eliminates the CBAM obligation entirely. The economics of the switch depend on the price differential between Tata Steel BF-BOF HRC and JSPL gas-DRI HRC — which is currently approximately Rs 500 to 1,000 per tonne premium for JSPL gas-DRI. At €59 per tonne CBAM saving (approximately Rs 5,250/t), the Rs 500 to 1,000/t premium for clean-route HRC is easily justified. This is the most direct and immediately actionable CBAM compliance strategy available to Indian pipe and tube exporters — and it does not require any capital investment at the tube producer’s own facility.
Frequently Asked Questions
Do pipes and tubes face CBAM even if the embedded steel is sourced domestically?
Yes — CBAM applies to the embedded emission of the imported product at the EU border, regardless of whether the steel input was produced domestically in India or imported from a third country. The CBAM obligation is calculated on the total embedded emission of the finished product (the pipe or tube) delivered to the EU, which includes the emission from the steel production process wherever it occurred. A pipe made entirely from Indian-domestic BF-BOF steel carries the same CBAM obligation as a pipe made from imported Chinese BF-BOF steel, because both have similar embedded emissions per tonne of steel. The geographic origin of the steel input is irrelevant — only the emission intensity of the production process matters.
How do Indian pipe exporters obtain verified upstream emission data from their steel suppliers?
There are three approaches. First, the pipe producer’s EU importer can request that the steel supplier provide heat-specific verified emission data — which requires the steel supplier to have plant-level CBAM MRV infrastructure and be willing to share the data. Tata Steel and JSW have both begun building CBAM emission data infrastructure and can in principle provide heat-specific data to downstream customers. Second, if heat-specific data is not available, the pipe producer can use the verified facility-average emission intensity of the steel supplier’s plant, which is less precise but acceptable under the CBAM Implementing Regulation. Third, if no supplier data is available, the EU importer must use the default EU value — which for BF-BOF steel is approximately 2.2 tCO₂/t, likely similar to actual Indian BF-BOF intensity, but significantly overstates the intensity of gas-DRI and scrap-EAF routes.
