Imports are tricky. One wrong digit on your customs form can delay your shipment for weeks or trigger a costly audit. I see this happen too often to good buyers.
The primary HS code for Electrolytic Tin Plate (ETP) is 7210.12.0000 for flat-rolled products wider than 600mm and thinner than 0.5mm. For thicker plates (0.5mm+), use 7210.11.0000. Always verify width and thickness to ensure compliance.
Let’s break down the details so you can clear customs without any headaches.
How do I calculate the import duty for HS Code 7210.12?
Money matters. You need to know exactly what a container costs to land in your warehouse before it even leaves my factory floor in Fujian.
Calculate the total duty by adding the standard ad valorem rate (usually free or low) plus any Section 232 tariffs (25%). Don’t forget the Harbor Maintenance Fee (0.125%) and Merchandise Processing Fee. These add up quickly on the final invoice.
When you are importing metal packaging materials, the "price per ton" I give you is just the starting point. To get your true landed cost, you have to peel back the layers of U.S. customs fees. It is not as simple as looking up one number. You have to look at the combination of standard duties and trade-action tariffs.
First, you have the Base Duty Rate. For most standard Electrolytic Tin Plate (ETP) under HS code 7210.12.0000, the Most Favored Nation 1 (MFN) duty rate is very low, often near zero or under 1%. This is the rate you see in the basic tariff books. However, this is rarely what you actually pay.
The biggest factor for my U.S. clients right now is Section 232 2. This is the trade expansion act that places a 25% tariff on steel imports from many countries, including China. This is not included in the standard HS code look-up. You must calculate this 25% on top of the commercial value of the goods. If you buy $100,000 worth of tinplate, that is an immediate $25,000 check written to Customs and Border Protection 3 (CBP).
Finally, you have the port fees. These seem small but they matter.
- Merchandise Processing Fee (MPF): This is an administrative fee for processing trade data. For formal entries, it is an ad valorem rate (a percentage of value), but it has a minimum and a maximum cap (usually around $614 max per entry).
- Harbor Maintenance Fee (HMF): If your goods arrive via ocean freight at a U.S. port, you pay 0.125% of the value of the cargo.
Here is a simple breakdown of how a hypothetical invoice looks when you land it:
Table 1: Estimated Landed Cost Breakdown (Example)
| Fee Type | Rate | Basis | Notes |
|---|---|---|---|
| Commercial Value | – | $50,000 | The price on my invoice (FOB/CIF) |
| Base Duty (MFN) | ~0% – 0.7% | $50,000 | Depends on exact sub-code |
| Section 232 Tariff | 25% | $50,000 | The major cost driver |
| HMF | 0.125% | $50,000 | Only for ocean freight |
| Merchandise Processing Fee 4 | ~0.3464% | $50,000 | Subject to min/max caps |
You must have your broker verify the Section 232 exclusions. Sometimes, if there is "insufficient domestic availability" in the U.S., you can apply for an exclusion, but this is a long legal process. For most spot buys, you should budget for the full 25%.
Are there currently any anti-dumping duties for Chinese tinplate?
This is the elephant in the room. As a manufacturer in China, I want to be 100% honest with you about the risks so you can plan safely.
Yes, Chinese tinplate imports are often subject to Anti-Dumping Duties (ADD) and Countervailing Duties (CVD). These rates change frequently based on Department of Commerce reviews. You must check the specific case numbers associated with the manufacturer before ordering.
Transparency is the most important part of our business relationship. I know that many buyers in the U.S. are scared of Anti-Dumping Duties 5 (ADD) and Countervailing Duties 6 (CVD). These are extra taxes the U.S. government puts on products they believe are being sold too cheaply (dumping) or are subsidized by foreign governments.
For Chinese tinplate, these duties can be very high. Sometimes, the combined rate of ADD and CVD can exceed 100% of the product value. This is why you cannot just buy from any random mill you find on the internet. You need to know the specific "Case Number" assigned to the factory.
Here is how it works:
- Country-Wide Rate: If a factory has not been individually investigated by the U.S. Department of Commerce, they get hit with the "China-wide" rate, which is usually the highest possible penalty.
- Separate Rate: Large, established manufacturers (like the state-owned mills we partner with for raw substrate) often participate in these investigations to prove they are not dumping. They get a "separate rate" which is much lower than the country-wide rate.
Do not try to cheat the system.
Some traders might suggest "transshipment." They will offer to ship the Chinese tinplate to Vietnam or Malaysia first, change the labels, and then send it to the U.S. to avoid the tax. Do not do this. U.S. Customs uses satellite tracking and metal analysis to catch this. If you are caught, you face massive fines and your company could be blacklisted.
We operate with full transparency. When we export to the U.S., we declare the correct country of origin. We help you calculate the real cost. Because our production costs are 5-8% lower due to automation, we can sometimes offset a portion of these tariffs, but we never hide them.
Table 2: Risk Levels in Tinplate Sourcing
| Sourcing Method | Risk Level | Consequence |
|---|---|---|
| Direct Import (Honest Declaration) | Low | You pay the duty, but supply is legal and stable. |
| Transshipment (Third Country) | Extreme | Seizure of goods, huge fines, legal action. |
| Unknown Supplier (No Case #) | High | You might get hit with the maximum "Country-Wide" penalty rate unexpectedly. |
Always ask your supplier: "What is your specific ADD/CVD case number?" If they cannot answer, walk away.
Can you help me with the correct documentation for US Customs?
Paperwork is boring, but it is the only thing standing between your factory and a stopped production line. I handle this daily.
I provide a complete Mill Test Certificate (MTC), a detailed Commercial Invoice, and a Packing List. The invoice must clearly state "Prime" or "Secondary" quality to match the HS code. Accurate weight reporting in kilograms is also non-negotiable.
When your container arrives at Long Beach or Newark, the customs officer does not look at the metal first; they look at the paper. If the paper is wrong, the metal sits on the dock, and you pay demurrage fees 7.
To clear HS Code 7210.12 smoothly, you need three specific things to be perfect:
1. The Commercial Invoice (Prime vs. Secondary)
This is where most mistakes happen. The HS code 7210.12 covers different quality levels.
- If you are buying Prime material (perfect condition), the invoice must state "Prime Electrolytic Tin Plate."
- If you are buying Secondary material (waste, over-rolled, or slightly defective sheets), you might use a code like 7210.12.10 or 7210.12.90 depending on the specific defect.
- The Trap: If you declare "Secondary" to get a lower value but the goods look "Prime," Customs will think you are lying about the value to pay less tax. If you declare "Prime" but ship rusty scrap, they will think you are money laundering. The description on my invoice will match the physical goods exactly.
2. The Mill Test Certificate (MTC)
This is the "ID card" for the steel. It proves the chemical composition and mechanical properties. For FDA compliance, this document is vital. It shows the tin coating weight (e.g., 2.8/2.8 g/m²) and the temper (e.g., T3 or DR8). If your customs broker gets asked, "Is this food grade?" the MTC is the proof they need.
3. Accurate Weights in Kilograms
The U.S. Harmonized Tariff Schedule 8 requires reporting quantity in kilograms. Even if we negotiate the price in Metric Tons or by the "Base Box" (a common unit in the canning industry), my packing list will always provide the Net Weight in kilograms. This matches the statistical reporting requirement for code 7210.12.
Table 3: Essential Import Documents Checklist
| Document Name | Key Element to Check | Why it matters |
|---|---|---|
| Commercial Invoice | Quality Grade (Prime/Secondary) | Determines the unit value and flags valuation fraud. |
| Mill Test Certificate 9 | Coating Weight & Temper | Proves the steel matches the HS description and FDA standards. |
| Packing List | Net Weight in KG | Required for U.S. Census statistical reporting. |
| Certificate of Origin 10 | "Made in China" | Determines if Section 232 or Anti-Dumping duties apply. |
Does the HS code change if the tinplate is printed or coated?
We often add value by coating or printing the metal here in Fujian to save you time. Does this change how you declare it?
Yes, if the tinplate is painted, varnished, or coated with plastics, the HS code shifts to 7210.70. This is distinct from standard plated steel. Misclassifying these value-added products can lead to incorrect duty payments and penalties.
This is a very common scenario for my clients. You might want to buy the tinplate already coated with a gold lacquer for tomato paste cans, or printed with your brand logo. We have 53 Fuji coating lines here, so we do this volume of work every day.
However, once we apply that coating, the product is no longer just "Electrolytic Tin Plate" in the eyes of Customs.
- Raw ETP: Classification 7210.12. This is steel that is only plated with tin.
- Coated/Painted ETP: Classification 7210.70. The description usually reads something like "Flat-rolled products… painted, varnished, or coated with plastics."
Why does this matter?
The duty rates can be different. Sometimes, the "Coated" category has a higher duty rate because it is a higher-value product. Other times, it might be subject to different trade exclusions.
The "Tariff Shift" Rule
In some free trade agreements (though not applicable to China-US trade right now), changing the classification from 7210.12 to 7210.70 is considered a "substantial transformation." But for U.S. imports from China, the main concern is accuracy.
If you import printed sheets for making cookie tins, and you declare them as raw tinplate (7210.12), Customs will eventually open that container. They will see colorful, printed metal instead of plain silver sheets. They will flag this as a misclassification. Even if the duty rate difference is small, the penalty for filing false information is high.
We assist you by clearly describing the product on the invoice. For example: "Electrolytic Tin Plate, Gold Lacquered on one side, Size 800x900mm." This description forces the broker to use the 7210.70 code, keeping you safe and compliant.
Conclusion
Getting the HS code right—7210.12 for standard or 7210.70 for coated—is the foundation of a profitable import strategy. It protects you from fines and keeps your supply chain moving.
