Import Tax from China to the US: Complete Guide (2026 Update)

You found a supplier, negotiated a great price, shipped the goods — and then a customs invoice arrives that's 25% higher than you budgeted. This is the most common "surprise" in importing, and it's completely avoidable: import taxes are knowable before you order, if you know where to look.

This guide explains the full stack of taxes and fees you'll face importing from China into the United States, how to calculate them, and the tools that make the job ten minutes instead of a weekend.

The Four Layers of US Import Cost

When your goods clear US customs, up to four separate charges stack:

Layer 1: Base customs duty (MFN rate)

The "normal" tariff the US applies to your product category for most-favored-nation trading partners (China's baseline treatment). Ranges widely:

• Many consumer goods: 0–10%
• Apparel and footwear: often 8–32%
• Electronics and tech components: frequently 0%
• Watches, jewelry, luggage: mid to high single digits and up

This rate is determined by your product's HTS code (Harmonized Tariff Schedule) — the 10-digit classification that decides everything. Getting the code right is the whole game; see our step-by-step guide: How to Find Your Product's HTS Code.

Layer 2: Section 301 tariffs (China-specific)

On top of the base duty, most Chinese-origin goods carry additional Section 301 tariffs — introduced in 2018 and adjusted multiple times since. The surcharge depends on which of the four lists your product falls under, and rates have ranged from 7.5% to 100%+ across categories and policy phases. What's critical to understand:

• The Section 301 rate applies on top of the base duty, not instead of it
• List membership follows the HTS code — a one-digit classification error can change your landed cost dramatically
• The lists get amended; a rate you verified a year ago may no longer be current

Layer 3: Merchandise Processing Fee (MPF)

A customs processing fee on formal entries: 0.3464% of the shipment value (ad valorem, with a minimum around $25–35 and a maximum around $500–600 per entry — figures adjust annually; verify current numbers). Informal entries (under $2,500) pay a small flat fee instead.

Layer 4: Harbor Maintenance Fee (HMF)

0.125% of value on ocean shipments only (not air). Small, but real, and often forgotten in napkin math.

The formula

Total import cost ≈ (Customs value × Base duty + Section 301 rate) 
                    + (Value × 0.3464% MPF, capped)
                    + (Value × 0.125% HMF, ocean only)

Customs value is generally the price paid for the goods (FOB basis for US entries — international freight is not dutiable in the US, unlike the EU). Practical example for a $10,000 shipment of an item with 8% base duty + 25% Section 301:

• Base duty: $800
• Section 301: $2,500
• MPF: ~$35
• HMF (ocean): $12.50
• Total: ~$3,347 → an effective 33.5% on top of goods cost

Now imagine that surprise on a $50,000 order — which is why you calculate before buying, not after landing.

Do You Also Pay Sales Tax?

• No federal sales tax on imports — customs duties are the federal layer.
• State sales/use tax: you may owe use tax on imported inventory in your state, and marketplace/economic nexus rules (post-Wayfair) can apply to your sales regardless. This is accounting territory, not customs — budget it separately and ask your accountant. It's a common blind spot for Amazon FBA sellers especially. (See our FBA compliance guide ← 内链集群十)

De Minimis: The $800 Question

The US previously exempted shipments under $800 from duty (Section 321 de minimis). This exemption has been the single most-changed rule in US–China trade, with restrictions and suspensions targeting Chinese-origin goods specifically. The era of duty-free small parcels from China is effectively over for most China-origin ecommerce shipments — the exact mechanics have shifted repeatedly.

What this means practically:

• Small direct-from-China shipments now face duty processing that used to be free
• If your model depended on de minimis (small consolidated air shipments), recalculate your landed cost now
• The workaround is honest one: consolidate into formal entries, classify correctly, and price the duty into your margin

Paperwork: What You Actually Need

1. Commercial invoice — values, terms, parties (accurate values — undervaluation is customs fraud, and CBP's targeting of it has sharpened)
2. Packing list — carton-level detail
3. Bill of lading / air waybill
4. Customs entry — filed by you or your customs broker (you'll want a broker for formal entries)
5. Customs bond — required for formal entries (typically annual continuous bond ~$50k coverage, or single-entry bond). See: Customs Bonds for US Importers

Customs Broker: Optional or Necessary?

For informal, low-value, simple-category shipments: you can self-file. For everything else — especially anything with Section 301 exposure, classification ambiguity, or regular volume — a broker earns their ~$100–200 per entry many times over:

• Correct HTS classification (and documentation if you want a binding ruling)
• Handling entries, ISF filing (the "10+2" security filing due before the vessel loads — late ISF means $5,000 penalties), and CBP communications
• Flagging duty-saving opportunities: exclusions, alternative classifications, first-sale valuation (see How to Reduce Import Duties Legally ← 内链)

Step-by-Step: Calculate Your Import Tax in 10 Minutes

1. Identify the product's HTS code — via the HTS search tool, starting from the chapter level (full walkthrough ← 内链)
2. Check the base (General/MFN) rate for that code
3. Check Section 301 applicability and current rate for that code (USTR's list documents / CBP's automated lookups, or ask your broker)
4. Note additional fees: MPF, HMF
5. Multiply out against your landed goods value
6. Sanity-check with a professional before committing to a large order — classification disagreements between you and CBP resolve in CBP's favor, with interest

Common Mistakes (and What They Cost)

FAQ

Is duty charged on the shipping cost? For US entries, duty is assessed on the customs value of the goods (generally FOB transaction value) — international freight is excluded from the dutiable base. (The EU works differently — VAT is charged on CIF including freight.)*

Can I get Section 301 refunded later? Refunds have been possible when exclusions were granted retroactively or when CBP reclassified goods. It happens — but plan your margins assuming what you pay at entry is what you pay.

What's an importer of record, and can it be me? The IOR is the party legally responsible for the entry — duties, compliance, and records. It can be you (you'll need an EIN and a customs bond), or your agent/broker structure. Whoever it is carries the liability, so choose deliberately.

Do I need to pay duty on samples? Commercial samples can qualify for entry without duty under certain provisions, but the paperwork still exists. Marked/destroyed samples have their own procedures — ask your broker rather than assuming.

Bottom Line

Import tax from China to the US is three stacked percentages plus fees — all knowable in advance from your product's HTS code. The importers who get hurt are the ones who treat customs as a surprise instead of a spreadsheet. Run the numbers before you order, use a broker once volume justifies it, and never build a business plan on exemption rules that are actively changing.
