Supply table

The supply table describes the supply of products which are produced domestically or imported and comprises three sections: domestic output by industries table (columns 1-15 in the table below), imports column (column 16), and margins[2] and taxes on products table (columns 18-21).

The domestic output table presents industries across columns and products across rows. The industry column shows the type of products produced by each industry and the rows show how much of each product is produced by the different industries. For example, the primary outputs of the manufacturing industry are manufacturing products (valued at $635 billion) whereas professional and business services (valued at $17 billion) represent a secondary output. In terms of market share, the manufacturing industry is the main producer of manufacturing products as it provides 98% of the product’s total domestic output. The wholesale and retail trade industry also produces manufacturing products; however, its contribution to total domestic output is less than 1%.

The imports column (column 16) shows imports of different products. The imports of manufacturing products are valued at $489 billion representing 43% of total supply of manufactured products at basic price[4]. The domestic output and imports tables show values of products at basic prices. The total supply at basic prices is shown in the supply table above in column 17.

The margins and taxes on products table shows products’ wholesale, retail, and transportation margins in addition to the taxes on products. It is included as part of the supply table in order to convert total supply values from basic prices to purchasers’ prices[5]. This transformation is necessary to match the supply of products with the use of products at the same price valuation. For example, the sum of domestic output and imports of manufactured products is $1,135 billion at basic prices. Adding margins and taxes on products of $373 billion brings the total supply of manufactured products to $1,508 billion at purchasers’ prices. Note that total supply at purchasers’ prices is identical to the total use of these product at purchasers’ prices (column 23 in the use table). This is a basic accounting identity in the SUT framework.
