When sourcing dietary supplements from a Chinese OEM manufacturer, the factory visit and product development phases are just the beginning. The real test of your supply chain comes when your products cross international borders—and customs clearance is where many brands encounter costly delays, unexpected fees, or even product seizures.
This guide walks you through the customs clearance process for importing supplements from China to the three largest markets: the United States, European Union, and Australia. Understanding these requirements helps you partner more effectively with your OEM manufacturer and avoid common pitfalls.
The Foundation: Documents Your OEM Partner Must Provide
Before your products leave China, ensure your OEM partner prepares a complete documentation package. Missing or incorrect documents are the leading cause of customs delays.
Core Documents (All Markets):
- Commercial Invoice: Declares value, quantity, and product description. Must match your purchase order exactly.
- Packing List: Details weight, dimensions, and carton count. Critical for freight calculations.
- Certificate of Origin (COO): Proves Chinese origin for duty assessment. May qualify for preferential rates under trade agreements.
- Certificate of Analysis (CoA): Verifies product specifications—potency, heavy metals, microbial counts, and other quality parameters.
- Bill of Lading (B/L) or Airway Bill: The transport contract and proof of shipment.
Supplement-Specific Documents:
- Health/Sanitary Certificate: Required for some markets; confirms product safety and compliance.
- Free Sale Certificate: States that products are freely sold in the exporting country.
- GMP/ISO Certificates: Demonstrates manufacturing quality standards.
United States: FDA and CBP Requirements
The US market has two agencies involved in supplement imports: Customs and Border Protection (CBP) handles duties and tariffs, while the Food and Drug Administration (FDA) ensures product safety and compliance.
FDA Requirements
Prior Notice: Before your shipment arrives, FDA must receive prior notice. This electronic submission includes product details, manufacturer information, and expected arrival time. Your customs broker or freight forwarder typically handles this.
FSVP Compliance: If you’re a US importer, you must have a Foreign Supplier Verification Program (FSVP) in place. This requires verifying that your foreign supplier (your OEM partner) meets FDA food safety standards. Documentation includes:
- Hazard analysis records
- Supplier verification activities
- Corrective action records
FDA Detentions: Common reasons for FDA detention include:
- Missing or improper labeling (Supplement Facts panel errors)
- Unapproved health claims (disease claims on supplements)
- Undeclared allergens
- NDI (New Dietary Ingredient) violations
- Heavy metal or microbial contamination
Mitigation Strategy: Ask your OEM partner for:
- Sample labels reviewed by US regulatory experts
- Third-party lab testing results (ISO 17025 accredited)
- NDI status confirmation for novel ingredients
CBP Requirements
Harmonized Tariff Schedule (HTS): Supplements typically fall under HTS codes in Chapter 21. Accurate classification determines duty rates. Misclassification can result in penalties.
Country of Origin Labeling: Products must be marked with their country of origin. For supplements manufactured in China, labels must clearly state “Made in China” or equivalent.
Section 301 Tariffs: Many Chinese-origin products face additional tariffs (currently 7.5-25% depending on HTS classification). Factor these into your landed cost calculations.
European Union: REACH, Health Claims, and Customs
The EU presents unique challenges due to its centralised regulatory framework (EFSA for health claims, REACH for chemicals) combined with national customs authorities.
Customs Clearance Process
EORI Number: Importers need an Economic Operators Registration and Identification (EORI) number. Apply through your national customs authority.
Product Classification: Supplements are typically classified under CN codes in Chapter 2106. Correct classification affects duty rates (most supplements face 0-12% duty).
VAT and Import Duties: Import VAT is charged at the destination country’s rate (17-27% depending on member state). Duties vary by product type and origin.
Regulatory Compliance
Novel Food Regulation: Ingredients not consumed in the EU before May 1997 require Novel Food authorisation. Your OEM partner must confirm ingredients are on the EU approved list or have authorisation.
REACH Compliance: Certain supplement ingredients fall under REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals). Verify compliance for any novel or synthetic compounds.
Health Claims: Only EFSA-authorised health claims can appear on labels. Using unapproved claims can result in market withdrawal and fines.
Common EU Detention Reasons:
- Unauthorised novel food ingredients
- Non-compliant health claims
- Missing allergen declarations (14 allergens per EU Regulation 1169/2011)
- Label not in the destination country’s official language
Australia: TGA and ABF Requirements
Australia has one of the strictest supplement regulatory regimes globally. The Therapeutic Goods Administration (TGA) treats most supplements as Listed Medicines, requiring pre-market entry on the Australian Register of Therapeutic Goods (ARTG).
Sponsor Requirement
Critical: Non-resident brands cannot directly enter supplements into Australia. You need an Australian-based sponsor who:
- Holds the ARTG entry
- Takes legal responsibility for product compliance
- Manages adverse event reporting
Your OEM partner can help connect you with sponsor services or act as your regulatory liaison.
Customs and TGA Clearance
ABF (Australian Border Force): Handles customs clearance, duty, and GST collection.
TGA Clearance: TGA reviews shipments to verify ARTG listing and compliance. Products not on the ARTG will be detained.
Common Australian Clearance Issues:
- Missing or invalid ARTG entry
- Sponsor not identified on shipping documents
- Ingredients not permitted in Listed Medicines
- Label non-compliance with TGO 91/92/93
Three Ways Your OEM Partner Can Smooth Customs Clearance
A proactive OEM manufacturer does more than produce your supplements—they help ensure products move smoothly across borders.
1. Pre-Shipment Documentation Package
Request a complete, market-specific documentation package 5-7 days before shipment. This should include all certificates, CoAs, and regulatory confirmations needed for your destination market.
2. Label and Compliance Pre-Review
Before production, your OEM partner should facilitate label review by market-specific regulatory experts. This catches compliance issues early, when corrections are inexpensive.
3. Third-Party Testing and Verification
Insist on ISO 17025-accredited third-party lab testing for each production batch. Results should be documented in CoAs accompanying shipments.
Conclusion
Successful customs clearance for supplements imported from China requires coordination between importers, customs brokers, regulatory authorities, and OEM manufacturers. By understanding the specific requirements of your target markets—US FDA/CBP, EU customs and EFSA, and Australian TGA/ABF—you can work proactively with your manufacturing partner to prevent delays, avoid costly detentions, and ensure your products reach consumers on schedule.
