Structure of the Chiral Scalar Superfield in Ten Dimensions
  We describe the tensors and spinor-tensors included in the $\theta$-expansion of the ten-dimensional chiral scalar superfield. The product decompositions of all the irreducible structures with $\theta$ and the $\theta^2$ tensor are provided as a first step towards the obtention of a full tensor calculus for the superfield.
