This guide covers everything you need to know about customs clearance when importing from China, applicable to most countries worldwide.

Required Documents for Customs Clearance
Standard Documents (All Countries)
| Document | Purpose | Who Provides |
|---|---|---|
| Commercial Invoice | Declares value, description, and terms of sale | Supplier |
| Packing List | Details of packages, weights, and dimensions | Supplier |
| Bill of Lading / Airway Bill | Proof of shipment and title to goods | Carrier |
| Certificate of Origin | Declares where goods were manufactured | Supplier/Chamber of Commerce |
| Import License (if required) | Permission to import restricted goods | Importer |

| FCC Certificate | Electronic products entering USA |
| Phytosanitary Certificate | Plant/wood products |

Understanding HS Codes
What Is an HS Code?
An HS (Harmonized System) code is an internationally standardized numerical code used to classify traded products. Every product has a unique HS code that determines:
- Customs duty rate
- Import restrictions
- Required certifications
- Statistical tracking
HS Code Structure
Example: 8471.30.01
84 = Chapter (Nuclear reactors, boilers, machinery)
8471 = Heading (Automatic data processing machines)
8471.30 = Subheading (Portable digital computers)
8471.30.01 = National tariff line (specific product)
Why the Correct HS Code Matters
| Consequence of Wrong HS Code | Impact |
|---|---|
| Wrong duty rate | Overpaying or underpaying duties |
| Missing restrictions | Goods refused entry or seized |
| Wrong documentation | Missing required certificates |
| Audit risk | Customs may investigate past shipments |
Tip: Always verify HS codes with your customs broker or freight forwarder. Don’t rely solely on your supplier’s classification.
How Customs Duties Are Calculated
The Basic Formula
Customs Duty = Customs Value × Duty Rate
What Is “Customs Value”?
Customs value is typically based on the CIF value (Cost + Insurance + Freight):
Customs Value = Product Price
+ Inland Freight (China)
+ Marine Insurance
+ International Freight
Total Import Cost Example
Importing $10,000 worth of electronics (HS code 8471.30) to the USA:
| Component | Calculation | Amount |
|---|---|---|
| Product price | – | $10,000 |
| International freight | – | $1,500 |
| Insurance | 0.5% of CIF | $58 |
| CIF Value | – | $11,558 |
| Customs duty (0%) | 0% × $11,558 | $0 |
| MPF (Merchandise Processing Fee) | 0.3464% (min $31.67, max$614.35) | $40 |
| HMF (Harbor Maintenance Fee) | 0.125% × $10,000 | $13 |
| Total customs fees | – | $53 |
| Import VAT (varies by state) | Not collected at import for most goods | – |
| Total landed cost | – | $11,611 |
Common Reasons for Customs Delays
| Reason | How to Avoid |
|---|---|
| Incorrect HS code | Verify with customs broker before shipping |
| Missing documents | Use a pre-shipment checklist |
| Under-declaration of value | Always declare actual transaction value |
| Missing certifications | Check requirements before ordering |
| Prohibited/restricted goods | Verify import regulations for your product |
| Inconsistent information | Ensure all documents match exactly |
| Name discrepancies | Use exact same company name on all documents |
| Vague product descriptions | Provide detailed descriptions on invoice |
| Improper packaging | Follow ISPM 15 for wooden packaging |
| Peak season congestion | Ship early, especially Q4 |
Customs Valuation Methods
The World Trade Organization (WTO) defines six methods of customs valuation, used in order of priority:
Method 1: Transaction Value (Most Common)
Based on the price actually paid or payable for the goods.
Customs Value = Price Paid to Supplier + Certain Additions
Additions may include:
- Selling commissions
- Royalties and license fees
- Value of assists (materials, tools provided to supplier)
- Proceeds of resale that benefit the seller
Method 2: Transaction Value of Identical Goods
Based on the value of identical goods sold for export to the same country.
Method 3: Transaction Value of Similar Goods
Based on the value of similar goods sold for export to the same country.
Method 4: Deductive Value
Based on the resale price in the importing country, minus certain deductions.
Method 5: Computed Value
Based on the cost of production plus profit and general expenses.
Method 6: Fallback Method
Based on reasonable means consistent with WTO principles.
Over 95% of imports use Method 1 (Transaction Value).
