Sourcing supplements from a Chinese manufacturer sounds straightforward in theory. Find a factory, agree on a formula, place an order. But move beyond the pilot run and you’ll quickly discover that international freight and customs compliance are a different beast entirely — one that has derailed more than a few promising supplement brands.
Whether you’re importing 20 bottles as market samples or 20 pallets in a 40-foot container, the underlying documentation and compliance requirements follow the same logic. Understanding that logic before you place your first real order will save you thousands of dollars, weeks of delays, and more than a few sleepless nights at the port.
This guide walks you through the export process from the Chinese factory floor to your destination market, covering documentation, Incoterms, customs clearance, and the shipping options most relevant to supplement buyers.

## The Documentation Foundation
Every international shipment — regardless of size — requires a set of core documents. Customs authorities in virtually every major market will ask for these before releasing your goods:
**Commercial Invoice.** This is your transaction record. It must accurately list the product description, quantity, unit price, total value, and country of origin. For supplements, description must be specific enough for tariff classification — “dietary supplement capsules” beats “health products” every time.
**Packing List.** Details the contents of each carton: number of units, net/gross weight, dimensions. Customs brokers use this to verify what’s actually in the shipment against the invoice.
**Bill of Lading (B/L) or Air Waybill (AWB).** The transport contract and proof of ownership. For sea freight this is a Master Bill of Lading (or House Bill if using a freight forwarder); for air it’s an AWB.
**Certificate of Origin (COO).** Issued by China Chamber of Commerce or a designated agency, this certifies that your products were manufactured in China. Required for preferential tariff treatment under free trade agreements and for customs clearance in most markets.
**Certificate of Analysis (COA).** Your manufacturer should provide this with each batch. It confirms that the product meets your agreed specifications — ingredient identity, purity, microbial limits, heavy metals. U.S. FDA, EU, and Australian authorities all expect to see this at customs.
For supplement shipments, you may also need:
– **Health/Phytosanitary Certificates** if your product contains plant-based ingredients
– **Halal or Kosher Certification** for relevant markets
– **Lab Test Reports** from third-party laboratories (Eurofins, SGS, Bureau Veritas) — increasingly expected by U.S. and EU customs, especially for ingredients like botanicals, probiotics, or fish oils

## Incoterms: Who’s Responsible for What
The Incoterms® rule you agree on with your manufacturer determines who bears the cost and risk at each stage of transit. For supplement buyers working with Chinese OEM factories, the most common options are:
**EXW (Ex Works).** The buyer arranges everything from the factory gate. Rarely used unless you have an experienced logistics team, because it puts maximum burden on the importer.
**FOB (Free on Board).** The manufacturer delivers the goods onto the vessel at the designated Chinese port. This is the most common term for ocean freight. You take ownership (and risk) once the goods are on the ship.
**CIF (Cost, Insurance and Freight).** The seller pays for carriage and insurance to the destination port. You take ownership once the goods arrive at your port. Useful for buyers who want one predictable price but still want control over the freight relationship.
**DDP (Delivered Duty Paid).** The seller handles everything — freight, insurance, customs clearance, and import duties — and delivers to your door. Highest cost but lowest complexity for the buyer.
For most supplement brands starting out, **FOB Shanghai or FOB Qingdao** (or the nearest major port to your manufacturer) combined with your own freight forwarder gives you the best balance of cost control and simplicity.

## Export Procedures from China
When your goods leave a Chinese port, Chinese customs handles export clearance. The factory or their logistics agent typically manages this, but as the buyer you should understand what’s happening:
**Export Declaration.** The manufacturer or their agent files an export declaration with Chinese customs, declaring the goods, value, and destination country. This generates the official export record.
**Customs Inspection.** For general merchandise (which covers most dietary supplements), inspection is typically document-based rather than physical, unless the goods are flagged for examination. Supplements containing certain botanicals or restricted ingredients may face closer scrutiny.
**Port Handling and Loading.** After customs clearance, the freight forwarder coordinates container loading, vessel booking, and departure. For LCL (Less than Container Load) shipments, your goods are consolidated with other shippers’ cargo at the port.

## Import Customs Clearance in Your Destination Market
This is where most delays and unexpected costs happen. Each major market has its own requirements:
**United States — FDA and CBP.** Dietary supplements are regulated by FDA as a food product, not a drug. Your shipment must be properly labeled and meet cGMP requirements under DSHEA. U.S. Customs and Border Protection (CBP) handles the physical clearance. You’ll need an FDA prior notice for food imports filed before arrival, and your broker will need accurate HS codes for tariff assessment. Common HS code for supplement capsules: 2106.90.
**European Union.** Under EU Food Information to Consumers Regulation (1169/2011), your label must be in the official language of the destination country. Products making any health claim must comply with EFSA’s approved claims register. Customs clearance in any EU member state grants access to the entire Union. The Import Control System 2 (ICS2) requires advance cargo declarations.
**Australia.** The Therapeutic Goods Administration (TGA) may require your product to be listed or registered before import. Foods assessed as therapeutic goods need a sponsor and TGA compliance. All imported food must meet FSANZ standards. AQIS (biosecurity) may inspect for prohibited ingredients.
**United Kingdom (Post-Brexit).** Following its own food supplement regulations (SI 2003 No. 1389), UK requires specific permitted vitamin and mineral forms. Health claims must align with the UK Food Standards Agency register. GB-specific customs procedures apply.

## Shipping Options: Sample to Full Container
**Express Courier (DHL, FedEx, UPS) — Sample Quantities.** For 1–50 kg, express courier is typically the fastest and most cost-effective option. Documents are handled by the courier. Transit time: 3–7 business days to most major markets. Be aware of the de minimis threshold — in the U.S., imports under $800 are generally exempt from customs duties but not from FDA review.
**Air Freight — Small Commercial Shipments.** For 100–500 kg, air freight via a forwarder (or direct booking with an airline cargo desk) offers reasonable pricing and faster transit (5–10 days). You’ll need a customs broker for clearance.
**LCL (Less than Container Load) — Growing Volumes.** When your order doesn’t fill a full container (typically under 15 CBM), LCL lets you share container space with other shippers. Your goods are consolidated at origin and de-consolidated at destination. Cost-effective for orders from 1–15 CBM. Transit: 20–35 days sea freight plus port handling.
**FCL (Full Container Load) — 20′ or 40′ Container.** For orders over 15 CBM (roughly 10+ pallets), FCL is the most economical option. A 20-foot container holds approximately 10–12 standard pallets; a 40-foot holds 20–24. FCL transit from major Chinese ports to U.S. West Coast: 14–20 days; East Coast: 28–35 days; Europe: 28–35 days; Australia: 14–21 days.

## The OEM Partner’s Role
A competent OEM manufacturer shouldn’t disappear once the goods are boxed. Your manufacturing partner should be able to:
– Provide documentation packages (COA, CI, PL, COO) in the format required by your broker
– Issue COA batch-specific to your production run, not generic spec sheets
– Advise on correct HS code classification for your product type
– Coordinate with your freight forwarder for container loading and vessel booking
– Communicate proactively on production timelines so you can plan logistics in parallel
At Zuoning Bio, our export documentation team works directly with your logistics partners to ensure shipments clear customs on the first attempt, not the third.
