10mm² BV Cable Supplier China: Specifications, MOQ and Wholesale Supply
Sourcing 10mm² BV cable from China is not simply a matter of finding a factory and asking for the lowest price per meter.
For importers, electrical distributors, contractors, wholesalers, and project buyers, the more important question is whether the quoted product actually matches the required conductor construction, insulation system, voltage rating, standard, packaging, and application.
A quotation may say “10mm² BV copper cable,” but that description alone does not tell a buyer everything needed to evaluate the product.
The conductor construction needs to be confirmed. The applicable standard needs to be identified. The insulation specification needs to be clear. Packaging and quantity can affect the final purchasing cost. Certification may also be important depending on the destination market.
This guide explains what buyers should know before purchasing 10mm² BV cable from a Chinese supplier, including technical specifications, MOQ, wholesale pricing, quality checks, RFQs, packaging, samples, and international sourcing considerations.
What Is 10mm² BV Cable?
BV is a commonly used designation for a type of PVC-insulated copper building wire in China.
The “10mm²” designation refers to the nominal cross-sectional area of the copper conductor.
It does not mean that the finished insulated wire has a 10mm diameter.
The finished outside diameter is larger because the conductor is covered by insulation.
For international purchasing, buyers should avoid treating “BV” as a complete universal specification. The exact product should be identified by its applicable standard, conductor construction, voltage rating, insulation requirements, and intended application.
When requesting a quotation, ask the supplier to state the complete product designation and applicable standard on the quotation and technical datasheet.
For buyers researching related building-wire products, our guide to BV Wire and 60227 IEC 01 provides additional background.
Typical 10mm² BV Cable Specification
The exact specification should be confirmed with the manufacturer, but a purchasing specification may contain the following information:
| Specification | Example |
|---|---|
| Product | 10mm² BV copper building wire |
| Conductor | Copper |
| Nominal conductor size | 10mm² |
| Conductor construction | Solid or construction required by the applicable standard |
| Insulation | PVC |
| Voltage rating | 450/750V where applicable |
| Color | Black, red, blue, brown, green/yellow, etc. |
| Standard | Required IEC, GB/T or applicable market standard |
| Packaging | Coil, roll or other agreed format |
| Quantity | According to buyer requirement |
These are purchasing examples rather than a universal specification for every BV product.
The final specification should be confirmed against the applicable standard and the electrical requirements of the destination market.
Why Do Buyers Use 10mm² Wire?
10mm² conductors are used in electrical applications where a larger conductor cross-section is required than common smaller building-wire sizes.
Depending on the installation design, applications may include:
- Distribution circuits
- Electrical panels
- Sub-feeds
- Commercial buildings
- Industrial installations
- Machinery connections
- Larger residential electrical circuits
- Equipment power connections
However, the conductor size should not be selected based solely on the intended load name.
Actual cable selection can depend on:
- Current
- Cable length
- Installation method
- Ambient temperature
- Number of loaded conductors
- Grouping
- Voltage drop
- Insulation temperature rating
- Local electrical regulations
A 10mm² conductor is therefore not automatically appropriate for every circuit requiring a particular current.
The electrical designer or applicable code should determine the required conductor size.
10mm² BV vs Smaller Wire Sizes
The cross-sectional area of a conductor has a direct relationship with its electrical resistance.
For the same conductor material and length, increasing the conductor cross-sectional area generally reduces resistance.
This is one reason larger conductor sizes are used for applications requiring different electrical characteristics.
However, bigger does not automatically mean better.
Using a larger conductor than necessary can increase:
- Material cost
- Cable weight
- Installation difficulty
- Conduit requirements
- Packaging volume
- Transportation cost

For projects requiring even larger conductors, our 16mm² copper cable buying guide explains the additional specifications buyers should consider.
Solid or Stranded 10mm² BV?
Conductor construction is an important point to clarify before ordering.
A buyer should not assume that every 10mm² copper wire offered under a similar product name has exactly the same construction.
Depending on the applicable standard and product type, the conductor may have a specified construction and conductor class.
Ask the supplier to confirm:
- Solid or stranded construction
- Conductor class
- Number of strands where applicable
- Conductor diameter
- Maximum DC resistance
- Applicable standard
This information is more useful than simply asking whether the product is “pure copper.”
A professional RFQ should request measurable technical information rather than relying on general descriptions.
PVC Insulation Requirements
The copper conductor is only one component of BV wire.
PVC insulation provides the electrical separation around the conductor, and its characteristics need to match the applicable product standard.
When comparing quotations, ask suppliers to confirm:
- Insulation material
- Nominal insulation thickness
- Minimum insulation thickness where applicable
- Finished wire diameter
- Rated voltage
- Temperature requirements
- Color
- Applicable testing requirements
Two wires may both be described as 10mm² PVC copper wire while having different specifications.
This is one reason why a professional buyer should compare technical datasheets instead of comparing product names alone.
For additional information about PVC building wire, see our article on PVC Insulated Building Wire for China Supply.
450/750V Rating
Many building-wire products are associated with a 450/750V voltage designation.
However, buyers should not assume that every product called BV automatically has the same voltage rating.
The quotation should identify the actual rated voltage.
The voltage rating needs to be considered together with:
- Product standard
- Insulation system
- Intended installation
- Environmental conditions
- Destination-market requirements
Our 450/750V electrical wire guide explains why the voltage designation should be treated as part of the complete product specification rather than as a standalone quality label.
What Standards Should a Buyer Request?
This is one of the most important questions when importing electrical wire from China.
A buyer should identify the standard required by the destination market or project.
Depending on the product and market, a quotation may reference:
- IEC standards
- GB/T standards
- BS standards
- EN standards
- Other national or project-specific standards
The supplier should clearly state which standard the quoted product is manufactured and tested against.
If the buyer requires a particular certification, the supplier should also confirm whether that certification covers the exact product, size, manufacturing location, and relevant standard.
Do not assume that a general company certificate automatically covers every cable produced by the supplier.
10mm² BV Cable MOQ in China
There is no single MOQ that applies to every Chinese BV cable manufacturer.
MOQ can depend on several factors:
- Cable size
- Cable color
- Total order quantity
- Packaging
- Custom printing
- Customer branding
- Certification
- Production schedule
- Factory capacity
- Whether the product is standard or customized
For example, a factory may accept a smaller trial order using standard packaging but require a larger quantity for customized printing or special packaging.
Therefore, instead of asking:
What is your MOQ?
ask:
What is your MOQ for 10mm² BV copper wire with our specified color, packaging, standard, and total quantity?
That question gives the supplier enough information to provide a meaningful answer.
Standard Product vs Customized 10mm² BV Cable
The MOQ can also change depending on customization.
A standard factory product may require less preparation.
Customized products can involve:
- Customer logo
- Custom printing
- Special colors
- Special coil lengths
- Private-label packaging
- Custom labels
- Customized reels or drums
- Special certification requirements
If you are a distributor planning to sell under your own brand, tell the manufacturer this at the beginning of the inquiry.
It is better to establish customization requirements before receiving the final quotation rather than adding them after the purchase order has already been confirmed.
How to Request a 10mm² BV Cable Quotation
A professional RFQ should contain enough information for the manufacturer to quote the same product you are asking other factories to quote.
For example:
Product: 10mm² BV copper building wire
Conductor: Copper
Size: 10mm²
Insulation: PVC
Voltage: 450/750V, if required
Standard: Required standard
Color: Blue
Packing: 100m coils
Quantity: 20,000 meters
Destination: [Country / Port]
Trade term: FOB or CIF
Certification: Required certification
Printing: Buyer logo if required
Then ask for:
- Unit price
- MOQ
- Production lead time
- Packaging details
- Gross weight
- Net weight
- Coil dimensions
- Technical datasheet
- Test report
- Available certification
- Sample policy
- Payment terms
- Quotation validity
This is much more useful than sending a message that only says:
Please give me your best price for 10mm² BV.
Our electrical wire RFQ guide provides additional examples of how buyers can structure an inquiry.
How to Compare 10mm² BV Cable Quotations
Suppose three suppliers send you prices.
Supplier A:
- USD X per meter
- Standard packaging
- 20-day lead time
Supplier B:
- USD Y per meter
- Customized packaging
- 15-day lead time
Supplier C:
- USD Z per meter
- Higher MOQ
- Lower unit price
- Different shipping term
The three prices cannot be compared properly until the specifications are standardized.
Create a comparison table:
| Item | Supplier A | Supplier B | Supplier C |
|---|---|---|---|
| Product specification | |||
| Conductor | |||
| Conductor construction | |||
| Insulation | |||
| Voltage rating | |||
| Standard | |||
| Price/meter | |||
| MOQ | |||
| Packaging | |||
| Lead time | |||
| Certification | |||
| Incoterm | |||
| Payment terms |
This approach makes it much easier to identify why one supplier appears cheaper.

What Determines the Wholesale Price?
The wholesale price of 10mm² BV cable can change with market and order conditions.
Factors may include:
Copper cost
Copper is the major conductor material, so changes in copper prices can affect cable quotations.
Order quantity
Larger orders may receive different pricing from smaller trial orders.
Packaging
Individual retail coils, cartons, reels, drums and customized packaging have different costs.
Insulation requirements
Different insulation specifications can change the production cost.
Certification
Special certification or testing requirements can add cost.
Customization
Logo printing, special colors and private-label packaging may increase the price.
Trade term
EXW, FOB and CIF quotations contain different cost components.
A buyer should therefore compare prices only after confirming that the quotations represent equivalent specifications and commercial conditions.
Why the Cheapest Quotation May Not Be the Cheapest Purchase
Imagine Supplier A quotes a very low price.
After receiving the quotation, you discover that:
- The packaging is different.
- The MOQ is much higher.
- Certification is excluded.
- Custom printing costs extra.
- The quoted price is EXW.
- Freight is not included.
Another supplier may have a higher factory price but provide the exact packaging, certification and FOB terms you actually need.
The second supplier could therefore produce a lower overall purchasing cost.
This is why total landed cost is more useful than factory price alone.
How to Check 10mm² BV Cable Quality
For a bulk order, buyers should establish a clear inspection procedure.
Conductor
Check:
- Material
- Cross-sectional area
- Construction
- Conductor resistance
- Surface condition
Insulation
Check:
- Material
- Thickness
- Surface condition
- Diameter
- Color
- Printing
Electrical performance
Where applicable, verify the required electrical tests according to the product standard.
Packaging
Check:
- Length per coil
- Number of coils
- Label information
- Carton condition
- Drum condition
- Shipping marks
Documentation
Check:
- Technical datasheet
- Test report
- Certificate
- Packing list
- Commercial invoice
- Other required export documents
For more information about inspecting copper wire before purchase, see How to Check Copper Purity and Conductor Quality Before Buying Copper Wire.
Should You Request a Sample?
For a first order, requesting a sample is often useful.
The sample should represent the specification that will actually be manufactured.
Check:
- Wire marking
- Color
- Insulation appearance
- Conductor construction
- Packaging
- Flexibility
- Dimensions
- Technical documentation
If the order is large or the cable is being used in an important project, buyers may also consider third-party inspection or laboratory testing according to the project’s requirements.
A sample is not a substitute for production quality control, but it gives the buyer a physical reference before committing to a large shipment.
Packaging Options for Wholesale Orders
Packaging should be specified in the RFQ.
Possible formats include:
- Small coils
- Large rolls
- Cartons
- Plastic reels
- Wooden reels
- Cable drums
- Customized export packaging
The best option depends on the buyer’s sales model and installation requirements.
A retail distributor may need clearly labeled 100m coils.
A project buyer may prefer longer lengths on reels or drums.
If you need a specific length, write it clearly:
100 meters per coil
or:
500 meters per wooden drum
Do not leave packaging as “standard packing” if packaging affects your sales or installation process.
How Long Does Production Take?
Production lead time varies between suppliers and orders.
Factors can include:
- Order quantity
- Factory schedule
- Product size
- Color
- Custom printing
- Packaging
- Certification
- Raw-material availability
A standard product may be easier to manufacture than a customized order.
Ask the supplier to provide a written production lead time in the quotation or purchase order.
For a large project, also ask when production will start and whether the supplier can provide a production schedule.
Can Chinese Manufacturers Provide OEM 10mm² BV Cable?
Many manufacturers can offer some form of OEM or private-label service, depending on their equipment and MOQ.
Possible customization may include:
- Customer brand
- Cable printing
- Coil labels
- Carton labels
- Packaging design
- Color requirements
- Product identification
Before approving OEM production, confirm exactly what will appear on the cable.
For example:
Brand name + size + voltage + standard + meter marking
The final marking should be reviewed and approved before production.
How to Verify a Chinese BV Cable Supplier
Before placing a significant order, buyers can ask the supplier for:
- Company registration information
- Factory address
- Product catalogue
- Technical datasheets
- Production photos
- Test reports
- Relevant certificates
- Export experience
- Sample
- Packaging examples
You can also ask whether the supplier can support factory inspection.
Being a manufacturer does not automatically mean that a supplier is suitable for your order. The key is whether the supplier can consistently produce the exact specification you require.
Our guide to finding an electrical wire manufacturer in China covers additional supplier-verification questions.
Questions to Ask Before Placing the Order
Before confirming a 10mm² BV cable purchase, ask the supplier:
- What exact standard does this product meet?
- What is the conductor construction?
- What is the maximum DC resistance?
- What insulation material is used?
- What is the rated voltage?
- What is the MOQ?

Frequently Asked Questions
What is 10mm² BV cable?
10mm² BV cable generally refers to a PVC-insulated copper building wire with a nominal conductor cross-sectional area of 10mm². The exact construction and standard should be confirmed with the supplier.
Is 10mm² BV cable suitable for high-current circuits?
It may be suitable for certain higher-load circuits, but allowable current depends on installation conditions, temperature, cable length, grouping, voltage drop, applicable standards, and local electrical regulations. The conductor size should be selected by the applicable electrical design.
What is the MOQ for 10mm² BV cable in China?
There is no universal MOQ. It can vary according to the manufacturer, quantity, color, packaging, customization, certification, and production requirements.
Can I buy 10mm² BV cable in different colors?
Many manufacturers can provide multiple colors, but available colors and minimum quantities should be confirmed for the exact product and order size.
Can a Chinese manufacturer put my company logo on the cable?
OEM printing may be available depending on the manufacturer, equipment, order quantity, and required marking. Confirm the exact printing content and MOQ before production.
Should I buy 10mm² BV cable by meter or by kilogram?
For purchasing comparisons, price per meter is often easier to understand when the product specification and length are fixed. Weight can also be important for logistics and freight calculations. Ask the supplier to provide both where appropriate.
What should I check before ordering 10mm² BV cable?
Confirm the conductor construction, cross-sectional area, insulation, voltage rating, standard, resistance, packaging, quantity, certification, lead time, and commercial terms.
How do I compare two 10mm² BV cable suppliers?
Send both suppliers the same technical specification and commercial requirements. Then compare their technical datasheets, samples, price, MOQ, packaging, certification, lead time, Incoterm, and total landed cost.
Is the cheapest 10mm² BV cable quotation the best option?
Not necessarily. A lower quotation may involve different specifications, packaging, certification, MOQ, or shipping terms. The products should be standardized before prices are compared.
Can I request a sample before a wholesale order?
Yes. A sample can help verify the product specification and appearance before mass production. For large projects, additional inspection or testing may also be appropriate.
Conclusion
Buying 10mm² BV cable from China requires more than finding a manufacturer with a low price.
The buyer should first define the exact product specification, including conductor construction, insulation, voltage rating, standard, color, packaging, and quantity.
After that, send the same RFQ to several qualified suppliers and compare their quotations on an equivalent basis.
For wholesale orders, pay particular attention to MOQ, copper specifications, packaging, certification, production lead time, OEM requirements, and total landed cost.
A disciplined sourcing process looks like this:
Define the specification → identify suitable suppliers → request samples → compare technical documentation → compare equivalent quotations → confirm packaging and certification → approve the final specification → place the order → inspect production → arrange shipment.
For international buyers, this approach is considerably more useful than choosing a supplier based only on the lowest price per meter.
A well-defined 10mm² BV cable specification also makes future repeat orders easier because the buyer and manufacturer have a clear technical reference for subsequent production.
