Commercial Invoice for Amazon FBA: The 2025 Guide to US Customs Compliance

A Commercial Invoice (CI) is the primary legal document used by U.S. Customs and Border Protection (CBP) to assess duties and by Amazon FBA to verify inventory ownership. Unlike a Proforma Invoice, a compliant CI must strictly identify the Importer of Record (IOR), provide valid 10-digit HTS Codes, and explicitly state the Country of Origin for every line item. Listing Amazon as the "Buyer" or under-declaring value are among the most common errors that trigger customs holds and serious account health issues in 2025.

I. Introduction: Why One Sheet of Paper Can Ruin Your Q4

If you are an Amazon FBA seller sourcing from China, you likely spend months perfecting your product and weeks negotiating shipping rates. But when the goods arrive at the Port of Long Beach or Los Angeles, the fate of your shipment often hangs on a single piece of paper: the Commercial Invoice (CI).

In our experience at Zbao Logistics—a China-to-USA freight forwarder specializing in Amazon FBA, DDP customs clearance, and 3PL distribution—we see a recurring pattern:

• The container arrives on time.

• The freight rate was cheap.

• But the cargo sits in a Customs Exam Station (CES) for 3 weeks.

Why? Because the factory wrote "Gift" on the invoice, listed "Amazon.com" as the buyer, or used a vague description like "Phone Parts." In the current regulatory climate of 2025—with heightened scrutiny on Section 301 Tariffs and UFLPA compliance—a sloppy Commercial Invoice is a business risk you cannot afford.

This guide is your operational manual. We will walk you through exactly how to create an Amazon FBA customs clearance & commercial invoice checklist that satisfies both US law and Amazon’s inbound rules.

II. The Role of CI: It Serves Three Masters

A common misconception is that the Commercial Invoice is just "paperwork for the shipping company." In reality, this document serves three distinct, legally binding purposes.

1. For US Customs (CBP): The Tax Bill

To CBP, the CI is a legal declaration of value used to determine duties (Ad Valorem, MPF, HMF) and check for prohibited items. It is the foundation of your Customs Entry.

2. For Amazon FBA: Proof of Ownership

Amazon is a fulfillment center, not a buyer. They require the CI to prove that you own the inventory. If you face a counterfeit claim or lost inventory issue, Amazon will demand a CI. If the "Sold To" field says Amazon, they may reject your claim.

3. For You (The Importer): Audit Trail

The CI is your primary document for accounting, tax audits, and Cargo Insurance claims. If goods are damaged, insurers pay out based on the commercial value listed on the invoice.

Zbao Expert Tip: Never confuse a Commercial Invoice with a Proforma Invoice. A Proforma Invoice is a preliminary bill for payment. Customs authorities do not accept Proforma Invoices for clearance. You must issue a final Commercial Invoice before the ship departs.

III. The "Must-Have" Fields: A Zbao Compliance Checklist

When we perform a Document Pre-Check for our clients, we verify these 7 critical data points.

1. Shipper / Exporter

This is typically the factory or trading company in China.

• Best Practice: It should be consistent with the manufacturer information you use for regulatory filings (e.g., CPSC/FDA where applicable), or at least traceable to that entity.

2. Sold To (Buyer) – The #1 FBA Mistake

This field causes the most confusion.

• WRONG: Amazon.com, 410 Terry Ave N, Seattle, WA.

• RIGHT: [Your Company Name], [Your Business Address].

The Risk: If you list Amazon as the buyer, CBP will expect Amazon to pay the duties. Amazon will refuse. If no valid IOR steps in to resolve the entry, the shipment risks being treated as unclaimed and may ultimately be returned, disposed of, or seized depending on circumstances.

3. Ship To (Consignee)

This is the physical destination.

• Format: Amazon.com Services, Inc. [Warehouse Code], [Full Warehouse Address].

• Example: Amazon.com Services, Inc. ONT8, 24300 Nandina Ave, Moreno Valley, CA 92551.

• Find the correct address in our Amazon FBA Warehouse Locations List.

4. Importer of Record (IOR)

The IOR is the entity legally responsible for paying duties.

• US Entity: Your Company Name + EIN.

• Foreign Seller: You must use a Foreign IOR setup, or use Zbao’s DDP Service where we act as the nominee IOR (subject to product eligibility and KYC approval).

5. Detailed Description & HTS Codes

Vague descriptions trigger exams. Use specific terms like "Stainless Steel Garlic Press, Manual" instead of "Kitchen Tool."

• HTS Codes: Provide the full 10-digit HTSUS code. This ensures accurate duty calculation. Learn more in our HTS Code Guide.

6. Country of Origin

• Best Practice: List the Country of Origin on every single line item, not just once at the header. This is critical if your shipment contains accessories or parts from different countries.

7. Incoterms

Explicitly state DDP (Delivered Duty Paid) or FOB (Free on Board). This tells Customs who is paying the tax.

IV. The "Value" Minefield: Avoiding Customs Penalties

The single most dangerous game importers play is Undervaluation.

The Scenario

You bought 1,000 units at **$10/unit** ($10,000 total). To save tax, your supplier writes **$2/unit** ($2,000 total) on the invoice.

The Reality Check

US Customs has access to global pricing data. If they flag your value as suspiciously low, they may issue a Request for Information (CBP Form 28) demanding proof of payment (bank wires).

• The Risk: If your payment doesn't match the invoice, you could face significant fines under 19 USC § 1592 for negligence or fraud.

• Zbao Policy: We advise declaring the Transaction Value (price actually paid).

VI. How to Avoid Amazon FBA Customs Clearance Delays with Zbao

At Zbao Logistics, we don't just take your paperwork and hand it to the broker. We perform a 3-Step Pre-Alert Audit.

Step 1: The "Data Match" Check

We cross-reference your Commercial Invoice against your Packing List.

• Does the total weight match?

• Does the total carton count match?

• Reason: Discrepancies here are the easiest way to get flagged for an exam.

Step 2: HTS Code Optimization

Our in-house team reviews your product description.

• Example: You classified a "Camping Light" as a "Flashlight" (25% duty). We re-classify it as a "Portable Lantern" (low/zero duty) if it meets technical criteria, saving you money legally.

Step 3: IOR & Bond Verification

If you don't have a US Customs Bond, we provide our Annual Bond or Single Entry Bond service under DDP terms, ensuring you have a valid Importer of Record before the ship sails.

VII. FAQ: Common Questions

Q: Can I use an Excel sheet as a Commercial Invoice?

A: Yes, the format doesn't matter as long as it contains all required data fields (Shipper, Buyer, Value, HTS, Signature) and is printed on company letterhead.

Q: Does the CI value include shipping costs?

A: It depends on the Incoterms. US Customs generally assesses duty on the FOB value (price paid for goods). Separating freight costs on the invoice (if you paid CIF) can sometimes lower your dutiable basis.

Q: Do I need to sign the Commercial Invoice?

A: Yes. A digital signature and company stamp are required to make it a valid legal declaration.

VIII. Conclusion: Paperwork is Profit

In international logistics, paperwork isn't just an administrative hurdle; it is the key to cash flow. A compliant Commercial Invoice ensures your goods clear customs in 24 hours rather than 24 days.

Don't let a clerical error derail your Q1 inventory planning.
