Wholesale procurement / Price & specification
A useful heavy duty tarp price starts with a shared specification. For importers, distributors and OEM buyers, this guide separates material, fabrication, reinforcement, accessories, packaging and freight so each quotation can be checked on the same basis. DERFLEX supplies PVC tarpaulin material and custom tarp formats; state whether you need rolls, panels or finished covers. Follow the clearly labelled cost model below, then submit the same drawing, quantity and delivery scope to request a comparable wholesale quote.

The practical answer
There is no useful single price without a defined tarp. Compare the same finished size, fabric construction, seam plan, reinforced edges, hardware count, quantity and delivery basis. A price per square metre of roll material does not include the same work as a price per finished cover.
Add any excluded insurance, duties, taxes, clearance and local delivery separately. Count each charge once. This guide models quote comparison; it does not publish a current price list.
01 / Establish a common basis
Send one specification revision to every supplier. Record exceptions next to the price rather than letting each supplier silently choose a different fabric, eyelet count or packing method. For material-only buying, begin with the PVC tarpaulin supply overview and specify usable roll width and length.
650 g/m² describes areal mass, not thickness or guaranteed strength. Use the GSM, thickness and weight guide to keep comparison units consistent. Agree acceptance tolerances and measurement conditions before an actual order.
02 / An auditable cost model
In this hypothetical wholesale tarp cost model, the main fabric allocation is 18.00 m² per cover: 15.00 m² of finished area plus a deliberately assumed 3.00 m² for the main-body hems, overlap and trim. Reinforcement is charged separately. This 20% uplift is a teaching assumption, not a normal factory allowance or a measured cutting yield.
Swipe horizontally to read the full calculation table.
| Cost layer | Explicit calculation / scope | USD / cover | USD / 100 covers |
|---|---|---|---|
| Main fabric | 18.00 m² allocated × assumed $2.40/m². Webbing and corner-patch material are excluded here. |
43.20 | 4,320.00 |
| Fabrication | Assumed charge for cutting, the model seam, hemming and attachment operations, including eyelet installation labour. | 6.80 | 680.00 |
| Reinforcement | Assumed webbing and four corner-patch material charge. Attachment labour is already in fabrication. | 4.50 | 450.00 |
| Accessories | 32 eyelet components × assumed $0.10 each. Installation labour is not charged again. | 3.20 | 320.00 |
| Packaging | Assumed individual pack, plain label and master-carton allocation. | 1.30 | 130.00 |
| Packed product subtotal | Sum of the five component charges above. | 59.00 | 5,900.00 |
| One-time setup | Assumed $100 per order ÷ 100 covers; not a second fabrication charge. | 1.00 | 100.00 |
| Goods + setup | Packed goods and the stated order fee, before transport. | 60.00 | 6,000.00 |
| Transport allowance | Model A: assumed $900 for the comparison transport scope. Model B uses the same scope at a different assumed rate. No actual freight offer is implied. | 9.00 | 900.00 |
| Model comparison total | Goods + setup + the stated transport allowance. | 69.00 | 6,900.00 |
Before transport, per finished area
$4.00/m²$6,000 ÷ (100 × 15.00 m²). The denominator is finished cover area, not the 18.00 m² fabric allocation.
Including model transport, per finished area
$4.60/m²$6,900 ÷ 1,500 m². This remains a scoped comparison total; excluded import and destination charges still need to be added.
A selling price can include overhead, margin and risk allowances within its rates. The example breaks down hypothetical quoted charges; it is not an open-book factory cost statement. For actual fabric consumption, request a panel layout and cutting-yield calculation rather than applying the model uplift.
03 / Bring offers onto the same scope
Both models below assume the identical EX-01 cover, 100 accepted pieces, the same packing and transport scope, the same currency and the same evaluation date. Model B's rates are also invented. Neither model represents a supplier or a historical transaction.
| Comparison line | Model A | Model B |
|---|---|---|
| Packed product unit charge | $59.00 | $57.80 |
| 100 packed covers | $5,900.00 | $5,780.00 |
| Separate setup fee / order | $100.00 | $180.00 |
| Transport / identical scope | $900.00 | $1,100.00 |
| Comparable scoped total | $6,900.00 | $7,060.00 |
| Total allocated per cover | $69.00 | $70.60 |
Model A is $160 lower for this defined scope. That follows only from these assumed charges. It says nothing about real suppliers, quality or future orders. If a quote excludes a required item, mark it incomplete until that charge is known.
Divide the same complete scope by the same accepted quantity or finished area. Use one exchange-rate date if currencies differ. Separate refundable deposits, optional tests and recurring charges from non-recurring fees.
A thinner fabric, omitted patch, unpriced inspection or smaller finished size changes the product. Ask for a revised compliant quote, or approve the deviation explicitly. A missing charge is not zero.
04 / What changes the quote
DERFLEX source photographs show different product formats. They do not establish the example's GSM, exact construction or test performance.
“Heavy duty”, “vinyl” and a colour name are insufficient identifiers. Fix the approved fabric or sample reference, nominal areal mass, tolerances and necessary test methods. Keep PVC-coated and laminated constructions distinguishable where the specification requires it.
List seam length, edge treatment, pockets, patches, cut-outs and printing. Roll width can change seam layout and usable yield. Ask which setup and conversion activities are included before adding another line.
Specify eyelet material, internal diameter, count, centre position and reinforcement detail. D-ring and strap assemblies need their own bill of materials. The grommet tarp specification guide explains the surrounding construction decisions.
Keep the drawing, colour, pack and acceptance requirements fixed across tiers. Ask how setup, packing and transport change with order size. Explore bulk tarp supply formats before choosing material or finished-cover procurement.
05 / Freight, exclusions & time
Record the delivery rule, its version and the named place or port in full. An EXW, FOB, CIF or delivered number cannot be compared by its label alone. Request a written inclusion list and align offers to the same cost boundary; cost allocation and risk transfer are separate questions.
| Commercial field | Required clarification | Why it affects comparison |
|---|---|---|
| Currency & price basis | Currency; price per roll, m² or finished piece; quantity tier; whether packing and fees are included. | Stops mixed units and double-counted charges. |
| Transport scope | Collection point, destination, freight mode, named delivery term and version, insurance scope and charge owner. | A freight allowance is not automatically a complete landed cost. |
| Packing measurements | Confirmed pack count, dimensions, gross mass, pallet requirement and stackability. | Fabric mass alone does not establish shipping volume or billable freight. |
| Destination exclusions | Clearance, terminal charges, duty, tax, inspection and onward delivery; mark each included, excluded or pending. | Unknown charges remain unknown, rather than being treated as zero. |
| Product quote validity | Issue date, exact expiry date and time zone, currency, specification revision and any adjustment triggers. | The same product may be quoted under different conditions at different dates. |
| Freight validity | Separate expiry, shipment window, rate confirmation basis and stated surcharges. | The product quote and freight rate may expire on different dates. |
| Payment & schedule | Payment terms, deposit conditions, sample approval, production start trigger and shipping window. | Price validity, production lead time and transit time are distinct commitments. |
The models on this page have no commercial validity. Actual quotes should state a calendar expiry rather than an undated “valid for 30 days” note. Reconfirm an expired product or freight quote before placing an order.
06 / Before you order
07 / Request a comparable quote
Send DERFLEX your finished size or drawing, material reference or application, quantity, fastening details, packing and destination. Ask for product charges, separate order fees and freight to be identified, with a written validity date and exclusions.
If you only have a sketch and an existing cover, start with those. The final quote still needs an agreed specification before it can be compared or accepted.

Procurement questions
No. It results from explicitly hypothetical component rates, a setup fee and a transport allowance for the model specification. It is not a historical quotation, market benchmark or offer. Request a current quote for your specification and destination.
Per-piece comparison works for identical finished covers. Per-square-metre comparison can help when you use the same finished-area denominator and scope. A raw fabric rate must remain separate because it excludes conversion and finished-cover details unless the supplier expressly includes them.
They may use different base fabrics, coatings, usable widths, finishing, tolerances or verification requirements. Seam layout, edge reinforcement and accessories also change the finished product. Match the material reference and drawing before interpreting the price difference.
No fixed reduction should be assumed. Order size can change the allocation of setup fees, material purchasing, packing and transport. Ask for quantity tiers with the same specification and list order-level fees separately.
Only if the actual quotation explicitly includes them within its written delivery scope. Check insurance, clearance, duties, taxes, terminal charges and onward delivery one by one. The transport allowances in this guide do not include those items.
Ask for a revised quotation referencing the current drawing, quantity, packing, destination and payment terms. Confirm product and freight expiry dates separately. Do not apply a previously quoted price to a changed specification without written acceptance.
