What Is Included in a Fiberglass Sculpture Quote
A fiberglass sculpture quote should itemize seven cost lines: design and 3D modeling, mould making, lamination and internal steel structure, surface finishing and paint, export crating, freight from China to your US address, and on-site installation. A complete quote states the sculpture's dimensions, wall thickness, finish system, and delivery terms (FOB or delivered). If any of these lines is missing or lumped into "miscellaneous," the price is not comparable to another supplier's bid.
Design and 3D Modeling
Most custom fiberglass sculptures begin with a concept drawing or reference image from the buyer. The design line in a quote covers converting that into a buildable 3D model, usually in software such as Rhino or ZBrush, plus a scale rendering you approve before tooling starts. Expect this line to be quoted separately or credited back against the production order — typical design fees run USD 300–1,500 depending on complexity, and many factories waive them once you place the order.
Ask whether the quote includes revision rounds. Two rounds of design changes is a common allowance; unlimited revisions usually means the supplier has not scoped the work. Also confirm who owns the model files after delivery — you should receive the final 3D file and production drawings, not just photos of the finished piece.
If your sculpture is a character or branded design, the design line should also state that you are supplying the licensed artwork and that the factory will not reproduce it for other buyers. That clause protects you and costs nothing to add.
Mould Making
The mould is the single largest fixed cost in a fiberglass sculpture project, and it scales with size and surface detail. A mould is typically made from fiberglass or silicone over a carved foam or clay master. Simple geometric forms in the 1–2 m range may need only a one-piece mould; a detailed figure at 3–5 m usually requires multi-part moulds with registration keys so the halves align.
Mould cost is charged once, so it dominates small orders and shrinks as a percentage on repeat runs. If you plan to order the same sculpture for multiple hotel or mall locations, ask for a mould retention price: storing the mould for future runs typically costs USD 200–500 per year or is free for a stated period, and it makes the second unit far cheaper than the first.
Confirm in writing whether the mould is included in the unit price or billed as a separate one-time line, and whether it is yours to keep or reuse elsewhere.
Lamination and Internal Steel Structure
The lamination line covers the fiberglass skin itself: resin type, glass content, and wall thickness. For outdoor public art, specify 6–8 mm wall thickness with an isophthalic or orthophthalic resin and UV-stable gelcoat; thin decorative panels for indoor retail displays can go down to 3–4 mm. Cheaper quotes often hide a 2–3 mm skin that will flex, craze, and crack within a season outdoors.
Every sculpture above roughly 1.5 m in height needs an internal steel armature to carry wind and its own weight. That frame — usually galvanized or powder-coated steel tube — should appear as its own line or be explicitly stated as included, with the steel gauge and anchor plate design described. A quote that mentions only "fiberglass body" without a frame is incomplete for any outdoor installation.
Ask for the resin and gelcoat brand or type, the glass content by weight, and whether the piece is rated for the wind load at your site. Coastal US locations and rooftop installations need heavier anchoring than sheltered indoor placements.
Surface Finishing and Paint
Finishing covers sanding, primer, base coat, color coats, and clear coat. Automotive-grade polyurethane paint with a UV-resistant clear coat is the standard for outdoor fiberglass sculpture and typically adds 10–20% to the lamination cost versus a basic gelcoat finish. Metallic, faux-bronze, faux-stone, and airbrushed gradients cost more because they require more masking and handwork.
The quote should state the paint system by name, the number of coats, and the expected service life before repainting — commonly 5–8 years for a quality polyurethane system in a moderate US climate. Ask for a color sample or painted swatch approval step before full production.
If your sculpture will be touched by the public, add a line for a protective clear coat or anti-graffiti coating; it is inexpensive at the factory and expensive to retrofit on site.
Crating and Export Packing
Fiberglass is strong in compression but easy to crack at edges and thin sections during shipping. A proper export crate is plywood on a timber frame, with the sculpture blocked and braced so it cannot shift, foam or bubble wrap on all painted surfaces, and desiccant packs inside. Crating is normally quoted as a separate line and scales with cubic volume, not weight.
As a reference, a 2 m sculpture typically ships in a crate of roughly 2.4 × 1.2 × 1.4 m, which is about 4 CBM. Crating for that size commonly runs USD 150–400. Oversized pieces may need to ship in sections with knock-down joints; if so, the quote must include the joint hardware and the assembly instructions.
Freight and Delivery Terms
Freight is the line buyers most often misread. A quote marked FOB Xiamen or FOB Shenzhen covers the goods loaded at the Chinese port — not ocean freight, not US port fees, not customs clearance, not trucking to your site. Ask for a CIF or delivered price as well so you can compare total landed cost between suppliers.
Sea freight for a 4 CBM crate from South China to a US West Coast port commonly falls in the USD 600–1,400 range for LCL, plus destination charges; a full 40HQ container is often more economical once your order exceeds about 25 CBM. Air freight is viable only for small pieces or urgent replacements.
Confirm who handles US customs entry, whether duties are included, and whether the factory will supply a commercial invoice, packing list, and HS code (fiberglass articles typically fall under HS 3926.90 or 7019.90 depending on construction — verify with your customs broker).
Installation
Installation is rarely included in a factory quote and should be priced separately. Options are: factory-supplied installation drawings and a supervisor who travels to site (common for large public art), a US-based installation contractor you hire directly, or a simple bolt-down kit for small pieces. A traveling supervisor typically costs USD 150–350 per day plus flights, visa, and lodging.
Whatever the arrangement, the quote should include anchor plate drawings stamped or reviewed by a local engineer where required, plus a lifting plan for anything over 500 kg. Confirm whether foundation work — concrete footings, conduit for lighting — is excluded, because it almost always is.

| Lamination | Wall thickness, resin type, glass content | Quoted per m² |
| Steel armature | Included or separate, gauge, anchor plates | Often 15–30% of body |
| Paint system | Brand/type, coats, clear coat, expected life | 10–20% of lamination |
| Crating | CBM, materials, knock-down joints | 150–400 per 4 CBM |
| Freight | FOB vs CIF vs delivered, port, Incoterm | 600–1,400 per 4 CBM LCL |
| Installation | Drawings, supervisor days, exclusions | 150–350 per supervisor day |
FAQ
Should a fiberglass sculpture quote include shipping to the USA?
Not by default. Most Chinese factories quote FOB, which ends at the port of loading. Ask for a CIF or delivered price as a second number so you can compare total landed cost, and confirm whether US customs duties and destination charges are inside or outside that figure.
Why do two quotes for the same sculpture differ by 50% or more?
The gap is almost always wall thickness, steel armature, and paint system. A 3 mm skin with a gelcoat finish and no internal frame can cost half of a 6–8 mm lamination with a galvanized frame and polyurethane clear coat. Ask both suppliers for thickness, resin type, and frame specification in writing before comparing price.
Is the mould cost refundable or reusable on a repeat order?
The mould is a one-time tooling cost, not a consumable. Ask for a written mould retention term — commonly free storage for 12–24 months, then USD 200–500 per year. Reusing an existing mould typically cuts the second unit's price by 20–40% versus the first.
