Customs clearance is one of the most intimidating parts of importing from China to Amazon FBA. One missing document or wrong HS code can delay your shipment by days — or even weeks.
This guide explains the entire US customs clearance process, required documents, duty calculations, and how to avoid common pitfalls.
What Is Customs Clearance?
Customs clearance is the process of getting your shipment approved by US Customs and Border Protection (CBP) for entry into the United States. It involves:
- Declaring what you're importing
- Paying applicable duties and taxes
- Proving compliance with US regulations
- Receiving CBP release to proceed to Amazon FBA
Who handles customs clearance? - If you ship DDP (Delivered Duty Paid): Your freight forwarder handles everything - If you ship FOB (Free on Board): You arrange a US customs broker yourself - If you use Amazon Global Logistics: Amazon handles customs

Understanding HS Codes and Duty Rates
What Is an HS Code?
The Harmonized System (HS) code is a 10-digit number used to classify products for customs. It determines: - Your import duty rate - Whether additional regulations apply - Whether the product is subject to Section 301 tariffs
How to Find Your HS Code
- Search the US Harmonized Tariff Schedule at hts.usitc.gov
- Search by product keyword or browse categories
- Verify the 10-digit classification
Common Product Duty Rates

| Electronics (phones, tablets) | 8517.13.0000 | 0% | 0% | 0% |

ISF (Importer Security Filing) Explained
What Is ISF?
The Importer Security Filing (ISF), also known as "10+2," is a mandatory pre-arrival filing for all sea freight imports to the USA. It gives CBP advance information about your shipment for security screening.
ISF Filing Deadline
- Must be filed at least 24 hours before vessel loading at the Chinese port
- Failure to file on time results in $5,000–$10,000 penalty
ISF Required Data Elements (10 from importer)
- Seller name and address
- Buyer name and address
- Importer of record number (EIN)
- Consignee number
- Manufacturer/supplier name and address
- Ship-to party name and address
- Country of origin
- HS code (6-digit minimum)
- Container stuffing location
- Consolidator name and address
Who Files ISF?
| Incoterms | Who Files ISF |
|---|---|
| DDP | Your freight forwarder (included in service) |
| FOB | You or your US customs broker |
| EXW | You or your US customs broker |
| FCA | You or your US customs broker |
Common Customs Issues and How to Avoid Them
| Issue | Cause | Solution |
|---|---|---|
| Shipment held for inspection | Random selection or flagged documentation | Ensure all documents are accurate and complete; use DDP |
| Wrong duty rate applied | Incorrect HS code classification | Verify HS code at hts.usitc.gov; consult customs broker |
| Missing FDA/EPA/FCC filings | Unaware of agency requirements | Check product regulations before shipping |
| ISF late filing penalty | Didn't file 24 hours before loading | Use DDP; forwarder handles ISF automatically |
| Under-valued shipment | Declared lower value to save on duties | Always declare true transaction value |
| Counterfeit goods seized | Product infringes trademarks | Verify product authenticity; obtain brand authorization |
| Wood packaging not treated | Pallets/crates not ISPM-15 certified | Use heat-treated or fumigated pallets (ISPM-15 stamp required) |
| Battery shipment rejected | Missing MSDS or UN38.3 test report | Prepare battery documentation before shipping |
DDP vs FOB: Which Is Better for Customs?
| Factor | DDP | FOB |
|---|---|---|
| Who handles customs? | Freight forwarder (all-inclusive) | You hire a US customs broker |
| ISF filing | Forwarder handles | You or your broker files |
| Duty payment | Forwarder pays (billed to you) | You pay directly to CBP |
| Risk of delays | Lower (forwarder is experienced) | Higher (if you're unfamiliar) |
| Cost transparency | All-in-one price | Separate fees (broker + duty + forwarder) |
| Best for | Most Amazon FBA sellers | Experienced importers with own broker |
Recommendation: For most Amazon FBA sellers — especially beginners — DDP shipping is strongly recommended. It eliminates customs headaches and lets your freight forwarder handle everything.
Working with a Customs Broker
If you ship FOB and need a US customs broker:
| What a Broker Does | Cost |
|---|---|
| File customs entry | $100–200 per shipment |
| Calculate and pay duties | Included in broker fee |
| File ISF | $25–50 per filing |
| Obtain customs bond | $50–500 (single entry); $500–5,000/year (continuous) |
| Handle CBP correspondence | Included in broker fee |
| Arrange cargo release | Included in broker fee |
How to choose a broker: - Look for licensed CBP brokers (check cbp.gov broker list) - Ask about experience with your product category - Compare fees across 2–3 brokers - Ensure they offer electronic filing (ABI/ACE)

Q: Do I need an EIN to import from China? A: Yes. You need an Employer Identification Number (EIN) from the IRS to serve as the Importer of Record for US customs. If you don't have one, apply at irs.gov (free).
Q: How much are customs duties from China to USA? A: It depends on your product's HS code. Rates range from 0% (many electronics) to 25%+ (products subject to Section 301 tariffs). Use hts.usitc.gov to find your rate.
Q: What happens if customs inspects my shipment? A: CBP may select your shipment for physical inspection (VACIS exam, intensive exam). This adds 2–10 days and $300–$1,000 in examination fees. You can't prevent random inspections, but complete documentation reduces the likelihood.
Q: Can I avoid Section 301 tariffs? A: Section 301 tariffs apply to products originating from China. You cannot legally avoid them by routing through another country. Some sellers have obtained exclusions for specific HS codes — check the USTR exclusion list.
