Global steel sourcing has become easier than ever, but it has also become riskier. Every year, thousands of buyers lose money due to supplier fraud, quality disputes, shipment shortages, and misleading promises.

After years of working with overseas buyers, we have seen many costly mistakes that could have been avoided with proper supplier verification and quality control.

In this article, we’ll reveal the 7 most common steel trade scams and show you how to protect your business when sourcing steel from China.

1. The Low-Price Trap

If a quotation is significantly lower than the market average, it should immediately raise a red flag.

Some suppliers intentionally offer extremely low prices to attract buyers. Once the order is placed, they may:

• Use lower-grade raw materials
• Reduce thickness or coating weight
• Add hidden charges later
• Delay delivery due to unrealistic pricing

How to Avoid It

• Compare quotes from multiple suppliers.
• Be cautious of prices that are 10–20% below market level.
• Ask for detailed specifications and production standards.

Remember: if a deal sounds too good to be true, it usually is.

2. Material Substitution

One of the most damaging scams involves delivering steel that does not match the agreed specification.

Examples include:

• Replacing Galvalume with Galvanized steel
• Using lower steel grades
• Substituting prime material with secondary material
• Mixing different grades in one shipment

These issues may not be visible until the product enters production.

How to Avoid It

• Request Mill Test Certificates (MTC).
• Conduct third-party inspections.
• Verify chemical composition and mechanical properties before shipment.

3. Thickness Shortage

Steel thickness directly affects product performance and value.

Some suppliers intentionally produce material below the specified thickness to reduce costs.

For example:

• Ordered: 0.50 mm
• Delivered: 0.45 mm

A small difference may seem insignificant, but across hundreds of tons, it can represent substantial losses.

How to Avoid It

• Clearly define thickness tolerance requirements.
• Use calibrated thickness gauges during inspection.
• Verify actual thickness before shipment.

4. Insufficient Coating Weight

For galvanized and galvalume products, coating weight is critical for corrosion resistance.

Some suppliers advertise:

• Z275
• AZ150

But actually deliver products with significantly lower coating weights.

This may reduce the service life of the steel by many years.

How to Avoid It

• Request coating weight reports.
• Perform laboratory testing when necessary.
• Verify coating specifications in contracts.

5. Disappearing After Receiving Payment

This is one of the most serious forms of fraud.

The supplier may:

• Request a large deposit
• Stop responding after payment
• Delay production indefinitely
• Completely disappear

Unfortunately, this still happens in international trade.

How to Avoid It

• Verify the company’s business registration.
• Confirm export history.
• Conduct factory audits.
• Avoid transferring large deposits to unverified suppliers.

6. Container Quantity Shortage

Not every scam involves product quality.

Some buyers discover after arrival that the shipment quantity is lower than what was paid for.

Common issues include:

• Fewer coils than ordered
• Lower actual weight
• Missing bundles
• Incorrect packing lists

How to Avoid It

• Conduct container loading supervision.
• Verify quantities during loading.
• Use independent inspection services.
• Request loading photos and videos.

7. Fake Factory, Real Trading Company

Many suppliers claim to be manufacturers but are actually trading companies.

There is nothing wrong with trading companies, but problems arise when buyers are misled.

Common signs include:

• Refusal to provide factory videos
• No production equipment
• No factory address
• Inconsistent company information

How to Avoid It

• Conduct virtual or physical factory audits.
• Verify production capacity.
• Check factory licenses and certifications.
• Request real-time factory videos.
