When ordering custom carbon fiber sheets, complete information is the key to receiving an accurate quotation. Many delays happen because the buyer asks for "carbon fiber sheet price" without confirming thickness, size, surface finish, quantity, cutting requirement, or application.
For B2B projects, a clear specification helps the supplier check availability, production feasibility, cost, packing, lead time, and document requirements. If you need visible woven sheets, please review our 3K Carbon Fiber Laminate Sheet product page before sending your inquiry.
Why Complete Specifications Matter
A complete specification reduces repeated communication and helps both sides confirm the same product. For example, a full sheet order is different from a CNC cut part order. A glossy 3K twill sheet is different from a matte plain sheet. A simple drawing may change the cutting method, packing method, and quotation structure.
Before requesting a price, buyers should prepare thickness, sheet size, surface finish, surface style, quantity, cutting requirement, tolerance, application, destination country, and document requirements.
Thickness and Sheet Size
The first item to confirm is thickness. Common carbon fiber sheet thickness options may include 0.5mm, 1mm, 1.5mm, 2mm, 3mm, 4mm, 5mm, or custom thickness. Thickness affects rigidity, weight, material usage, machining time, packing, and price.
The second item is sheet size. Buyers may request standard sizes such as 400 x 500mm, 500 x 500mm, 1000 x 1000mm, or custom dimensions. If you need finished parts instead of full sheets, provide drawings with length, width, hole position, slot size, and edge shape.
If you are not sure which thickness to choose, read our guide: How to Choose Carbon Fiber Sheet Thickness for Your Project.
Surface Finish and Surface Style
Surface finish should be confirmed before quotation. Common options are glossy, matte, and semi-matte. Glossy finish is usually selected for visible parts where the carbon fiber pattern should be clear and reflective. Matte finish is selected when lower reflection and a technical appearance are preferred. Semi-matte finish provides a balanced look.
Surface style is another important detail, especially for 3K carbon fiber sheets. Buyers may choose 3K twill, 3K plain, or other surface styles if available. 3K twill has a diagonal woven appearance. 3K plain has a more regular grid-like appearance. Forged carbon style may be available as a separate visual option depending on production capability.

Cutting, Holes and Custom Shapes
Cutting requirement can strongly affect quotation. A full sheet price is different from a CNC cut part price. If you need drilled holes, slots, chamfers, countersunk holes, special contours, or custom shapes, provide technical drawings.
DXF, DWG, STEP, PDF, or clear dimensioned drawings can help the supplier review machining feasibility. If the drawing is not available, provide a clear size list and photos of the intended part. For drawing-based machining, please review our CNC Carbon Fiber Sheet page.
Tolerance Requirements
Tolerance should be stated when it is important. General sheet tolerance, cutting tolerance, hole tolerance, and thickness tolerance are different topics. If your assembly requires tight fit, specify the required tolerance in the drawing. If tolerance is not critical, tell the supplier that general cutting tolerance is acceptable.
This helps avoid unnecessary cost and allows the supplier to choose a practical process. Do not use vague wording such as "high precision" without actual values when tolerance is critical.
Application and End Use
Application and end use should also be provided. The supplier does not need confidential project details, but a general application helps confirm whether the selected sheet is suitable. Examples include civil composite parts, industrial panels, tooling fixtures, sports equipment components, marine composite parts, machine covers, electronic equipment panels, and custom machined panels.
Application information helps the supplier understand requirements for surface finish, rigidity, tolerance, and packing.
Documents, Samples and Delivery Terms
Destination country and delivery terms are needed for export communication. Provide the destination country, port or address, and preferred delivery term if available. Packing should also be discussed. Full sheets may require protective film, carton, wooden case, or pallet packing. CNC cut parts may need separated packing to protect surfaces and edges.
Finally, confirm document requirements before quotation. Buyers may need TDS, COA, MSDS, sample, or test report for internal approval or incoming inspection. If a sample is needed before bulk order, confirm sample thickness, size, surface finish, cost, and shipping method.
