Frequently Asked Questions  and  Fiberglass Customs Tariff Guide

What payment terms are acceptable? Usual payment is by irrevocable letter of credit (L/C) payable at sight.
Can you offer extended payment terms? In some cases an extended payment term can be offered such as 30 or 60 days. However the payment has to be by irrevocable letter of credit (L/C) payable in 30 or 60 days at sight. The price may be slightly higher on an extended L/C payment term.
How about samples? Small samples are free of charge. Larger samples often free except for freight charges. If you need a few tonnes of samples then a charge will be made for the samples and sea (or air) freight.
What's the origin of fiberglass? Fiberglass is from various countries including China, Korea, India, Australia, South America, and USA.
Time for delivery? Goods are usually shipped within 7 to 30 days after L/C payment is confirmed.
Container loads with mixed goods available? It is often possible to have a 20ft container loaded with two or more types of fiberglass - say 1/2 loaded with Rovings and 1/2 with Chopped Strand Mat - as long as the goods come from the same factory.
Quality concerns? You can get samples from us to check the quality. If you need a large batch of samples to test on your production line, we will be happy to co-operate with you. Once you approve of the samples, we then ship the container loads of fiberglass - the exact same quality as the samples you checked.
Do you have a standard price list? No standard price is available at this time. Prices are changing all the time and we will quote a price on your particular inquiry. The price can include delivery (C&F) to your nearest major sea port, or (FOB) free-on-board the vessel at country of origin.
What is your minimum order? A 20ft container load - about 15 tons of roving, or 7 tons of chopped strand mat.
E-Glass and C-Glass - what's the difference? The main difference between C-glass and E-glass is the percentage alkali content. E-glass is suitable for electrical insulation. Whereas C-glass fiberglass has greater resistance to acid and corrosive chemical substances. For the appearance, FRP products made with E-glass are more transparent than C-glass. Tensile strength is slightly more superior with E glass. C-glass is available in woven roving, roving, chopped strand mat, and others. Price for c-glass is about 10% less than for e-glass materials.
Fiberglass Fabrics: "Greige" (loom state) Greige is the term used to describe glass cloth that has not been cleaned after weaving. It is in the "loom state" or has had no additional fabric finishing since the loom.
