THICK TRANSLUCENT PAPER CODE
The HS code for tracing paper is 4806.30. Natural tracing paper for laser printing is usually uncoated. The sizing in production will determine whether it is for laser printer or inkjet/ offset printing. Tracing paper is resistant to oil, grease and to a large extent impervious to water and gas. When the treated paper is thoroughly washed and dried, the resultant product is much stronger than the original paper. The acid converts some of the cellulose into amyloid form having a gelatinous and impermeable character. As with 2, by making a normal sheet of paper, which is followed by immersing uncut and unloaded paper of good quality in sulfuric acid for a few seconds.Due to the relatively high cost, this method of manufacture has largely disappeared.

The product was frequently called Vellum, although this terminology can refer to a wider range of special papers. This was a common process adopted in the USA.
