`
there is a high degree of substitutability between domestically produced quartz surface 
products and quartz surface products imported from China.  
Lead times 
Quartz surface products are primarily sold from inventory. U.S. producers reported that 
88.7 percent of their commercial shipments came from inventories, with lead times averaging 
10 days. The remaining 11.3 percent of U.S. producers’ commercial shipments were produced‐
to‐order, with lead times averaging 20 days. Importers reported that 83.9 percent of their 
commercial shipments came from U.S. inventories, with lead times averaging 12 days. 
Importers reported 14.4 percent of their commercial shipments were produced‐to‐order, with 
lead times averaging 82 days. The remaining 1.7 percent of their commercial shipments came 
from foreign inventories, with lead times averaging 57 days.

Twenty‐seven purchasers indicated they had marketing/pricing knowledge of domestic 
product, 40 of Chinese product, 19 of Israeli product, 13 of Spanish product, and 18 of all other 
nonsubject countries. 
As shown in table II‐5, most purchasers and their customers never make purchasing 
decisions based on the producer or country of origin. Of the five purchasers that reported that 
they always make decisions based on the manufacturer, firms cited varying reasons including
