Amorphous Silica Fabric

The product covered by this order is woven (whether from yarns or rovings) industrial grade amorphous silica fabric, which contains a minimum of 90 percent silica (SiO2) by nominal weight, and a nominal width in excess of 8 inches. The order covers industrial grade amorphous silica fabric regardless of other materials contained in the fabric, regardless of whether in roll form or cut-to-length, regardless of weight, width (except as noted above), or length. The order covers industrial grade amorphous silica fabric regardless of whether the product is approved by a standards testing body (such as being Factory Mutual (FM) Approved), or regardless of whether it meets any governmental specification. Industrial grade amorphous silica fabric may be produced in various colors. The order covers industrial grade amorphous silica fabric regardless of whether the fabric is colored. Industrial grade amorphous silica fabric may be coated or treated with materials that include, but are not limited to, oils, vermiculite, acrylic latex compound, silicone, aluminized polyester (Mylar[supreg]) film, pressure-sensitive adhesive, or other coatings and treatments. The order covers industrial grade amorphous silica fabric regardless of whether the fabric is coated or treated, and regardless of coating or treatment weight as a percentage of total product weight. Industrial grade amorphous silica fabric may be heat-cleaned. The order covers industrial grade amorphous silica fabric regardless of whether the fabric is heat-cleaned. Industrial grade amorphous silica fabric may be imported in rolls or may be cut-to-length and then further fabricated to make welding curtains, welding blankets, welding pads, fire blankets, fire pads, or fire screens. Regardless of the name, all industrial grade amorphous silica fabric that has been further cut-to-length or cut-to-width or further finished by finishing the edges and/or adding grommets, is included within the scope of this order. Subject merchandise also includes (1) any industrial grade amorphous silica fabric that has been converted into industrial grade amorphous silica fabric in China from fiberglass cloth produced in a third country; and (2) any industrial grade amorphous silica fabric that has been further processed in a third country prior to export to the United States, including but not limited to treating, coating, slitting, cutting to length, cutting to width, finishing the edges, adding grommets, or any other processing that would not otherwise remove the merchandise from the scope of the order if performed in the country of manufacture of the in-scope industrial grade amorphous silica fabric. Excluded from the scope of the order is amorphous silica fabric that is subjected to controlled shrinkage, which is also called ``pre-shrunk'' or ``aerospace grade'' amorphous silica fabric. In order to be excluded as a pre-shrunk or aerospace grade amorphous silica fabric, the amorphous silica fabric must meet the following exclusion criteria: (l) The amorphous silica fabric must contain a minimum of 98 percent silica (SiO2) by nominal weight; (2) the amorphous silica fabric must have an areal shrinkage of 4 percent or less; (3) the amorphous silica fabric must contain no coatings or treatments; and (4) the amorphous silica fabric must be white in color. For purposes of this scope, ``areal shrinkage'' refers to the extent to which a specimen of amorphous silica fabric shrinks while subjected to heating at 1800 degrees F for 30 minutes. Also excluded from the scope are amorphous silica fabric rope and tubing (or sleeving). Amorphous silica fabric rope is a knitted or braided product made from amorphous silica yarns. Silica tubing (or sleeving) is braided into a hollow sleeve from amorphous silica yarns.
