Detailed description
If the last shipment had edges fraying, a width that measured wide on arrival, or a peel that read low in incoming inspection, the cause is almost always in one of the four items described on this page rather than in the price.
What the buyer is choosing
Grade and backing are separate decisions. The same woven face is supplied plain for stitching, coated with acrylic for panels, or coated with rubber for rough and low-energy surfaces. Buying the face and the backing as one item is what produces the 'it stuck for a week then fell off' complaint.
The material question
This is a nylon-polyester blend rather than a single fibre. The nylon share carries the cycle life and the colour depth; the polyester share carries dimensional stability and the price. Blends are quoted by ratio, so if the ratio is not stated, the two quotes you are comparing are not for the same product.
How it is quoted
Payment is 30 percent deposit with the balance against a copy of the bill of lading. Mixed widths on one purchase order are quoted as separate lines with a shared lead time, which is usually cheaper than splitting the order.
What ships with the goods
Certificates are issued per lot rather than per year, and REACH and RoHS declarations travel with the shipping documents. OEKO-TEX documentation is available on request for skin-contact applications.
Checking it on arrival
Check the colour in the light the product is sold under. Warehouse fluorescent and daylight will disagree on dark greens and navies, and a lot rejected in one light is often accepted in the other. If it matters, agree the viewing condition before the order, not after.
Ask for a sample at your width; it ships in seven days and it settles the substrate, colour and hand questions faster than any specification sheet.
