Import duty from Vietnam to the US is usually estimated based on the product’s U.S. HTS code, customs value, country of origin, and applicable U.S. import fees. A product name or supplier quote alone is not enough to estimate duty accurately.
Import duty is not the same as freight cost, customs broker fee, destination charge, or final delivery cost. This article focuses on duty-related cost planning only, not the full shipping from Vietnam to USA process.
Quick Answer: How Is Import Duty from Vietnam to US Calculated?
| Question | Short answer |
|---|---|
| What determines import duty? | Mainly the U.S. HTS code, customs value, country of origin, and product type. |
| Does every Vietnam import pay duty? | No. Some products may be duty-free, while others may have standard or special duty rates. |
| What is the HTS code? | The U.S. tariff classification used to determine duty rates and reporting categories. |
| What value is duty based on? | Usually the customs value shown on the commercial invoice, subject to customs valuation rules. |
| What are MPF and HMF? | U.S. import-related fees that may apply separately from duty. |
| Are duties included in freight quotes? | Usually not, unless the quote clearly states a DDP-style or duty-included scope. |
| What is the biggest duty mistake? | Using a vague product description or supplier HS code without U.S. HTS review. |
Estimated import duty = customs value × duty rate
This formula only estimates the duty portion. MPF, HMF, broker fees, bond fees, freight, destination charges, and final delivery may still need to be added for landed cost.

What Determines Import Duty from Vietnam to US?
Vietnam origin does not automatically mean duty-free. The duty rate still depends on product classification and U.S. tariff rules.
| Factor | Simple explanation |
|---|---|
| HTS code | Determines the tariff category and duty rate. |
| Customs value | Duty is usually estimated from the declared value on the commercial invoice. |
| Country of origin | Confirms whether the goods are actually made in Vietnam. |
| Product type | Material, function, and use can change classification. |
| Special trade measures | Some products may be subject to additional rules or special duties. |
| Broker / CBP review | Final treatment may depend on broker review or CBP determination. |
For official classification research, importers can check the Harmonized Tariff Schedule, but final classification should usually be confirmed with a customs broker or official customs source when the product is not simple.
HTS Code for Vietnam Imports
The HTS code determines the duty rate. The supplier’s HS code is only a starting point because it may be based on Vietnam export declaration rules, not U.S. import classification.
A “bag” is not enough for duty review. A polyester backpack, plastic-coated tote bag, leather handbag, and cotton shopping bag may not follow the same classification logic.
A “metal part” is also not enough. A steel furniture bracket, aluminum machine part, and general-purpose screw may need different classification review because material, function, and use may change the HTS path.
This is why importers should give the broker clear product details, photos, material, use, and supplier code before estimating duty. If you also need to understand how classification fits into entry preparation, see customs clearance from Vietnam to USA.
Customs Value and Declared Value
Duty is often estimated from the customs value shown on the commercial invoice. The invoice should show accurate product value, quantity, unit price, currency, buyer, seller, and country of origin.
For example, if the invoice says 1,000 units at USD 20 each, the commercial invoice value is USD 20,000. Duty estimation usually starts from that declared value, subject to customs valuation rules.
Undervaluing goods to reduce duty can create customs questions, shipment delays, penalties, or future compliance problems. If the value is not straightforward because of assists, tooling, discounts, or special terms, ask your broker to review the valuation before shipping.
Duty, MPF, HMF, Broker Fee, and Freight Cost Are Different
Importers often mix duty with transportation charges. They are not the same. Separating each cost item helps you understand the real landed cost from Vietnam to the US.
| Cost item | What it means | Is it import duty? |
|---|---|---|
| Import duty | Tariff or customs duty based on HTS code and customs value | Yes |
| MPF | Merchandise Processing Fee charged on many U.S. import entries | No, but it is an import-related government fee |
| HMF | Harbor Maintenance Fee that may apply to certain ocean imports | No, but it is an import-related government fee |
| Customs broker fee | Service fee for entry filing or customs work | No |
| Customs bond fee | Cost for single-entry or continuous bond if needed | No |
| Freight cost | Sea, air, express, LCL, or FCL transportation charge | No |
| Destination charges | Port, CFS, terminal, warehouse, or handling charges | No |
| Final delivery | Trucking, parcel delivery, appointment, or FBA delivery | No |
If you are comparing full transportation pricing, read shipping cost from Vietnam to USA separately. This article focuses on import duty and duty-related planning.
CBP publishes current user fee information, including MPF references, through its User Fee Table. Importers should confirm current MPF, HMF, minimums, maximums, and applicability with CBP or their broker before shipping.
DDP vs Duty-Unpaid Shipping from Vietnam to US
DDP vs duty-unpaid is mainly a quote-scope issue. A duty-unpaid quote usually means the buyer or importer pays duty-related charges separately. A DDP-style quote may include duties depending on the written quote scope.
Do not assume DDP always includes every charge. Importers should confirm exactly what is included and excluded before booking.
| Question to ask | Why it matters |
|---|---|
| Are import duties included? | Prevents surprise duty bills after arrival. |
| Is MPF included? | MPF may apply separately from duty. |
| Is HMF included for ocean freight? | HMF may apply to certain sea shipments. |
| Is customs broker service included? | Broker fee is not the same as import duty. |
| Is the customs bond included? | A bond may be required for formal entry. |
| Are destination charges and final delivery included? | These are logistics costs, not duty. |

How Import Duty Affects Landed Cost
Import duty affects landed cost because it adds to the product cost and freight-related charges. A simple landed cost formula is:
Estimated landed cost = product value + estimated duty + MPF/HMF if applicable + broker/bond fees + freight + destination charges + final delivery
Example format:
| Cost item | Example input |
|---|---|
| Product value | USD 20,000 |
| Estimated duty | Duty rate × customs value |
| MPF/HMF | Check current official rules or broker estimate |
| Freight | Quoted separately |
| Destination charges | Quoted separately if applicable |
| Final delivery | Based on ZIP code and address type |
This does not create a guaranteed landed cost. It simply helps importers separate duty-related costs from freight and delivery charges before they compare suppliers or shipping quotes.
For broader cost-saving methods, read cheapest way to ship from Vietnam to USA separately. Duty planning and shipping method selection are related, but they are not the same topic.
Import Duty by Shipping Method
The shipping method does not usually change the basic duty logic. HTS code, customs value, and origin remain the main duty factors. But billing and related fees may differ.
- Sea freight: Duty logic is still based on HTS, value, and origin. HMF may be relevant for certain ocean shipments.
- Air freight: Duty logic is the same, but airport handling and broker costs may be billed differently.
- Express: Courier may bill duties and taxes to the receiver, sender, or account holder depending on setup.
- Amazon FBA: Amazon generally does not pay import duty for third-party sellers. Sellers should plan duty before FBA delivery. For more context, see Amazon FBA shipping from Vietnam to USA.
For entry preparation, see customs clearance from Vietnam to USA, but keep in mind that this article is focused on duty planning only.
Common Import Duty Mistakes
- Using the supplier’s HS code without U.S. HTS review. Supplier export codes may not match U.S. import classification.
- Providing vague product descriptions like “accessory” or “plastic product.” Duty review needs material, use, and product details.
- Assuming Vietnam origin means duty-free. Some Vietnam-origin products may be duty-free, but many are not.
- Assuming the freight quote includes duties. Many quotes are duty-unpaid unless DDP-style scope is written clearly.
- Confusing customs broker fee with duty. Broker fee is a service charge, not a tariff.
- Forgetting MPF, HMF, bond, or exam-related charges. These may affect landed cost even when the duty rate is low.
What Information Should You Send for a Duty Estimate?
A useful Vietnam-to-US duty estimate needs more than a product name. Send enough detail for the forwarder, broker, or destination agent to understand the product and quote scope.
| Information needed | Example |
|---|---|
| Product description | Wooden dining chair / polyester backpack / stainless steel bottle |
| Material | Wood, steel, plastic, polyester, aluminum |
| Main use | Household use / industrial part / retail product |
| Product photos or spec sheet | Photos, catalog page, technical drawing |
| Country of origin | Made in Vietnam |
| Commercial invoice value | USD 20,000 |
| Quantity | 1,000 units |
| Unit price | USD 20 per unit |
| HTS code if known | 10-digit U.S. HTS code if available |
| Shipping method | Sea, air, or express |
| DDP or duty-unpaid quote scope | DDP, duty-unpaid, or not sure |
| Destination ZIP code | 90021 / 07036 / 60106 |
| Amazon FBA warehouse code if any | ONT8 / LAX9 / FTW1 |

FAQ
How is import duty from Vietnam to US calculated?
Import duty is usually estimated by multiplying customs value by the duty rate from the correct U.S. HTS code. MPF, HMF, broker fees, bond fees, and logistics charges may still need to be added for landed cost.
Do imports from Vietnam to the US always have duty?
No. Some products may be duty-free, while others may have positive duty rates. Vietnam origin does not automatically mean duty-free. The product’s HTS classification must be checked.
Is the supplier’s HS code enough for U.S. import duty?
Usually no. The supplier’s HS code can be a starting point, but U.S. importers usually need the correct U.S. HTS code for duty review.
What are MPF and HMF?
MPF is Merchandise Processing Fee, and HMF is Harbor Maintenance Fee. They are import-related fees that may apply separately from duty, depending on entry type and shipment mode.
Are duties included in shipping quotes from Vietnam?
Not always. Many shipping quotes exclude duties unless the quote clearly states a DDP-style or duty-included scope. Always confirm what is included in writing.
Does DDP shipping include import duty?
DDP-style shipping may include import duty depending on the written quote scope, but importers should confirm duties, MPF, HMF, broker fees, bond, destination charges, final delivery, and exclusions.
Conclusion
Import duty from Vietnam to the US depends on HTS classification, customs value, country of origin, and applicable U.S. import fees. Importers should separate duty from freight cost, broker fees, destination charges, and final delivery.
A practical approach is to prepare clear product details, confirm HTS classification with a broker when needed, and clarify whether the quote is DDP-style or duty-unpaid before shipping.
