Karwon Composites quotes carbon fibre rods, sheets, tubes, profiles, fabrics and prepreg into the UAE.
Most composites enquiries take three rounds of email before a price can be issued. Round one asks for a quote. Round two is the supplier asking questions. Round three is the answers. Only then does anything get priced, and by then a week has gone.
Almost all of that delay is avoidable. The information a supplier needs is short and predictable, and an enquiry that carries it can usually be priced in a single pass.
Here is what to include, and why each item exists.
The three questions that block every quotation
If you send nothing else, send these.
1. What exactly, in the units the material is made in.
Not "carbon tube". Outside diameter, wall thickness, length. Not "carbon fabric". Weave, areal weight in gsm, width. Not "carbon plate". Thickness, sheet size, layup.
The most common single problem is a specification given in the wrong parameter. Fabric asked for by thickness rather than gsm. Wrap material asked for by thickness rather than areal weight and layer count. Prepreg asked for by cured ply thickness rather than fibre areal weight and resin content. Each of these forces the supplier to guess or ask.
2. How much, and whether it repeats.
Quantity drives price more than almost anything else, and a one off order and an annual requirement are priced differently for good reasons. If this is a prototype that becomes a production item, say so, including the anticipated annual volume. That sentence alone frequently changes a quotation materially.
3. What the part does.
The item most often omitted and the one that adds the most value. A supplier who knows the application can tell you when a cheaper grade is adequate, when your specification will not work, and when a different form solves the problem better.
If you tell us you need carbon rod, we can quote carbon rod. If you tell us it is a UAV boom carrying a specific load over a specific span, we can tell you whether a tube would be lighter and stiffer for the same money, which it often is.
Some buyers withhold the application deliberately, treating it as commercially sensitive. That is a fair instinct in some negotiations and it is usually counterproductive here, because it removes the supplier's ability to help you and guarantees you get quoted exactly what you asked for, right or wrong.
The rest of the checklist
Grade or performance requirement. T300, T700, T800, a high modulus grade, or a stated property you need to hit. If you do not know, give the load case and let the supplier work it out.
Tolerance on the one dimension that matters, and explicit relaxation on the ones that do not. Tolerancing everything tightly is the fastest way to a high price.
Surface finish, if it matters. Cosmetic twill and matte structural finish are different products at different prices, and a part nobody sees does not need a cosmetic surface.
Any origin requirement, and whether it is contractual or preferred. Non-Chinese origin carries a real premium and a real lead time implication. If it is a hard requirement, saying so upfront avoids a quotation you cannot use.
Certification or documentation required. State what your customer or consultant needs at goods inward. Documentation requirements are far easier to arrange before the order than after the material has shipped.
Your delivery need, with the date and its consequence. "As soon as possible" is not information. "We need it on site by the 20th because the crew mobilises that week" is, and it tells the supplier whether to quote air freight, whether to propose an alternative already moving, or whether to be honest that they cannot help.
Delivery location. Free zone and mainland differ for customs purposes and the difference affects both cost and paperwork.
Drawing, where one exists. A dimensioned sketch is enough. It does not need to be a finished CAD model, and a photograph of a hand drawing beats three paragraphs of description.
Two things that quietly slow everything down
Sending an enquiry to eight suppliers with no context. Everyone recognises a mass enquiry and everyone deprioritises it, so you get slow, generic, defensive pricing from all eight. Three suppliers with a proper brief will beat eight with a line of text every time.
Asking for a price before you know the quantity. A price without a quantity is a guess, the supplier will guess conservatively, and you will compare guesses. If the quantity genuinely is not known, give a range and ask for break points. That is a real question with a real answer.
The template
Copy this, fill it in, send it to anyone.
Product: [rod / tube / sheet / profile / fabric / prepreg]
Specification: [dimensions in the correct parameters]
Grade: [or the load case if unknown]
Quantity: [this order]
Repeat: [one off / annual volume if known]
Application: [what the part does]
Critical dimension: [the one that matters, and its tolerance]
Relaxed on: [where you have freedom]
Surface finish: [if it matters]
Origin requirement: [contractual / preferred / none]
Documentation: [what your customer needs at goods inward]
Delivery needed by: [date, and what depends on it]
Delivery to: [location, and free zone or mainland]
Drawing attached: [yes / no]Thirteen lines. It will save you a week on most enquiries, and it will get you better technical input than a longer email that omits the application.
What you should expect back
A quotation worth having states the specification it is pricing, the basis it is quoted on including the Incoterm, what is and is not included, the lead time, the validity period, and the payment terms.
If a quotation does not state its Incoterm, you cannot compare it to anything, and that is the first question to ask back.
