The Rotterdam premium for 99.9% low-lead tin increased to $1,000-1,100 per tonne due to stronger demand for high-purity material. Standard tin premiums remained unchanged at $900-950 per tonne. European premiums continue to receive support from high freight and financing costs. LME available stocks declined to 5,430 tonnes, although the underlying tin price softened to $54,819 per tonne.
