A fire at Tata Steel UK's Port Talbot mill on the evening of 3 June was restricted to the pickling line, a company representative has told Argus. Market participants say it could affect galvanising, oiling and painting processes, as well as hot-dipped galvanised (HDG) output.
"All personnel were accounted for and evacuated from the area safely. At this time, the emergency services remain on site and are working with local teams to completely extinguish the fire. The incident is not related to the safe and successful demolition of the empty, redundant gas holder earlier yesterday evening," Tata Steel UK said.
"The hot mill was unaffected and will restart [as soon as possible]," a company representative told Argus. He added that Tata Steel UK has "a reasonable inventory", but that it is "too early to say" whether customer deliveries will be delayed. It is also unclear whether downstream galvanising or other coated products supplied from Tata's UK network will be affected, or whether any pickled/oiled, hot-rolled or galvanised substrate output will be disrupted, he said.
Repair of the pickling line may take some time, and these works could hit HDG output, some participants said. But the company might try to restart its Llanwern unit, about 46 miles away.
"Converting slab into hot-rolled coil is still possible, but converting hot-rolled coil into pickled product is not, at least until the Llanwern line is... restarted," a market participant said. "Tata has some feedstock stock at Llanwern, so galvanising can continue for now... It may take about two weeks to restart this unit."
The fire occurred amid tense discussions over UK steel safeguard quotas, which take effect on 1 July. On 2 June, the UK introduced a transitional exemption mechanism that could soften the impact of import quotas. Under this arrangement, relevant goods under contract before 14 March will be exempt from the 50pc out-of-quota duty that will apply until 30 September.
The exemption was granted following the efforts of a working group led by the International Steel Trade Association and comprising the British Constructional Steelwork Association, British Independent Reinforcement Fabricators Association, British Stainless Steel Association, Confederation of British Metalforming, Metal Packaging Manufacturers Association and National Steel Association, a trader said. "[The Port Talbot fire] will have an effect on the market. It shows the high risk of relying on single source of steel."
In October 2024, Tata Steel ceased ironmaking at Port Talbot and paused steelmaking pending construction of a 3.2mn t/yr electric arc furnace that is due to be commissioned in late 2027-early 2028. During that period, the business will import slab and hot-rolled coil to support manufacturing and distribution in Wales, England and Northern Ireland, as well as Norway, Sweden, France, Germany and the UAE.
Tata Steel UK deliveries totalled 520,000t in January-March. Deliveries for the fiscal year to 31 March 2026 hit 2.2mn t, down from 2.51mn t a year earlier because of "subdued market dynamics", according to Tata.
