This article is for importers and companies that bring products from abroad. It is especially useful if you are now reviewing a new product, a new production partner, or a new country of supply.

It does not matter much whether you already have import experience or you are only starting. I see the same mistake in both cases.

Many companies begin with the product. They search for a factory, compare supplier prices, check samples, discuss packing, and only later, sometimes almost at the end, ask a customs broker:

In my opinion, this is the wrong sequence. Import duties, anti-dumping duties and country of origin should be checked at the beginning, not after the supply option has already been locked.

Why duties matter before you choose a supplier

When goods arrive in the destination country, customs clearance begins. At that moment, the importer starts dealing with taxes, duties and other costs that directly affect the final product cost.

Two things can seriously change the economics of a shipment:

• import duty;
• anti-dumping duty.

Import duty is common. Almost every product has a customs code and a duty rate.

Anti-dumping duty is less common, but when it applies, it can destroy the entire deal structure.

This is why the country of origin matters. The same product from China, Vietnam, Thailand, India, Bangladesh or another country can have a completely different final cost. Not only because the factory price is different, but because the customs treatment can be different.

What import duty is

Every product has a customs code. A pen, a mobile phone, phone components, paper, clothing, a microphone, packaging film, dried fruit - everything has a customs code.

Each code has its own import duty rate. In simple terms, the duty is usually calculated based on the value of the goods and the transport cost.

Rates can be different: 0%, 3%, 5%, 10%, or higher, depending on the product and country.

If the duty rate is 0%, it does not mean the shipment is free from all costs. There may still be VAT, customs broker fees, port charges and other expenses. But if you can legally reduce or avoid import duty, the difference can be significant.

What anti-dumping duty is

Anti-dumping duty is a different story. It is usually introduced when imported goods are considered a threat to local producers.

For example, imagine a country has a large tire factory. It employs many people. It is important for the local economy. The government or private investors have invested serious money into it.

Then foreign tires enter the market at a much lower price. Maybe the foreign product is better. Maybe it is cheaper. Maybe it has more stable quality. But from the state’s point of view, this can create pressure on local producers.

So the government may introduce anti-dumping duties. The goal is simple: to protect the local market from imports sold at a price that is considered too low or unfair.

Let’s say the local tire costs 10 dollars per unit. You see an imported tire that can be sold for 7 dollars. At first, it looks like a strong opportunity.

But if an anti-dumping duty applies, your final cost may become higher than the local product. And the whole import idea stops working.

The common importer mistake

Many importers think like this:

A good broker is important. No question. But if you involve the broker too late, you may already be working with the wrong country, the wrong producer and the wrong cost model.

The better approach is different. Before you commit to a supplier, check:

• which countries can produce this product;
• what import duties apply from each country;
• whether anti-dumping duties apply;
• whether there are free trade agreements;
• what certificate of origin is required;
• how logistics will work;
• what the final landed cost will be.

Only after that does it make sense to compare producers seriously.

Why China is not always the cheapest option

China is the global manufacturing base. I work with China myself, and I understand why importers go there.

The choice is huge. The supplier base is deep. For many product groups, you can visit one region and find dozens of factories. You can compare samples, packing, specifications and prices quickly.

For an importer, China can look like paradise.

But this does not mean China always gives the best final cost.

The same product may also be produced in Vietnam, Thailand, India, Bangladesh or another country. Sometimes the quality is similar. Sometimes it is slightly lower. Sometimes the factory price is even higher.

But after import duties, anti-dumping duties and logistics are calculated, another country may become more attractive.

Certificate of origin is not just a “Made in Vietnam” label

To use a preferential duty rate, you usually need to prove the origin of the goods. That is where the certificate of origin comes in.

This is not just a sticker on the box. You cannot simply write “Made in Vietnam” and expect customs to accept it.

A certificate of origin is an official document. It confirms that the goods were produced or sufficiently processed in a specific country under the applicable rules.

Some people oversimplify the issue:

This is not how it works.

If the goods are already finished and you only repack them, that does not make them Vietnamese. To receive origin, there must be real production, assembly, processing, local value added, or another qualifying operation depending on the rules for that product and country.

There must be a real basis for the certificate. Without that, the certificate may not be issued. And without the certificate, you may not be able to claim the preferential duty rate at destination.

Example: packaging film from China to Vietnam

Let me give one example from trade in packaging materials.

Vietnam is a large market for packaging film. The country has strong agriculture, food production and export activity. Packaging is needed everywhere.

Vietnam produces a lot locally, but it also imports large volumes, especially from China.

Before Covid, some large Chinese producers supplied serious volumes of film into Vietnam. One manufacturer I spoke with used to ship up to about 8,000 tons per year.

That is a huge volume. Roughly speaking, it can be close to one 40-foot container per day.

Chinese film took a serious share of the market. The price was competitive. The quality was stable. Many buyers preferred working with Chinese suppliers, even if they had to wait for production and shipment.

At some point, local producers saw this as a threat. They complained to the authorities that some Chinese suppliers might be dumping products into the Vietnamese market.

After review, anti-dumping duties were introduced for several Chinese producers. The rate was around 27%.

The Chinese suppliers lost their market position. Their model stopped working. For several years, these duties blocked or reduced their ability to compete in the same way.

Only later were these measures removed, and Chinese suppliers started to return. But the volumes were not the same as before.

Why lowering the invoice value is dangerous

Some people may say:

At first, it sounds simple. The product costs 10 dollars, but the invoice says 5 or 7. Customs calculates duty from the lower value, and the importer saves money.

But this is a dangerous idea.

Customs authorities are not naive. They have data. They see many shipments. They know average values for product groups.

There is a concept of customs value. If you declare a value that is much lower than normal, customs may ask questions.

You may say: “This is our real price. We found a very good supplier.”

Fine. Then you may be asked to prove it. And if the declared price is not real, proving it will be difficult.

Customs may adjust the value, add duties and create additional checks. In some cases, the problem can affect future shipments too.

Why changing the country only on paper does not work

Another idea some people have:

For example, purchase the goods in China, move them to Vietnam, repack them, add a Made in Vietnam label and ship them further.

Again, this is too simple.

If the goods are already finished, authorities can see that. If the operation in Vietnam is only repacking, it may not qualify for Vietnamese origin.

For origin, you need real processing, production, assembly or another qualifying operation. You need documents. You need a real production process. You need a valid basis for the certificate.

A label is not enough.

How to choose the country of supply correctly

The logic should be this. Before choosing the final supplier, check:

Sometimes a Chinese factory may give the best unit price, but the final cost is worse because of duty or anti-dumping measures.

Sometimes another country may have a higher factory price, but a lower duty rate and better final economics.

Sometimes China still wins, even with duty, because logistics are simpler and cheaper.

The point is simple: you need to calculate the full picture. Supplier price alone tells you very little.

Where to check duties

There are open online tools that allow you to check duty rates in advance. Usually you can enter:

• country of origin;
• country of destination;
• product description;
• HS code, if you already know it.

These tools can show estimated duties, restrictions and trade agreement benefits.

But final confirmation should still be done with a customs broker or trade specialist in the destination country. This is especially important if the product is expensive, regulated, sensitive or potentially covered by special measures.

Main takeaway

If you import goods, do not start only with the question:

Start with:

The producer is only one part of the deal. Country of origin, HS code, certificate of origin, import duty, anti-dumping duty and logistics can be more important than a small difference in factory price.

If you check all this at the beginning, you can save money, time and problems at customs.
