🧪 Peptone (Protein Hydrolysate)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Logistics Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Peptone"?
Peptone is a generic name for the partial hydrolysis products of proteins. It is a mixture of peptides and amino acids obtained from the enzymatic or chemical digestion of animal or plant proteins. In international trade, it is primarily used as a raw material for fermentation industries, biological culture media (microbiology), and pharmaceutical production.
In international customs classification, Peptone is generally classified based on its source material:
1. Peptone from Animal/Plant Sources: Classified under Chapter 35 (Albuminoidal substances; modified starches; glues; enzymes).
2. Peptone from Milk (e.g., Casein Peptone): May sometimes fall under dairy derivatives depending on specific processing, but usually remains in Chapter 35.
⚠️ Key Distinction Point:
- If it is a pure protein hydrolysate (no other added substances except buffers/salts in trace amounts) → Classified under 3502 or 3504.
- If it is mixed with vitamins, sugars, or agar (ready-to-use culture media) → Classified under 2936 or 3004 (if medicinal) or 3824.
- Standard Trade Item: Most "Peptone" shipments refer to the white/yellowish powder from soybean, casein, or meat, which falls under Chapter 35.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Source Material |
|---|---|---|---|
3502.20.00.00 |
Casein and caseinates (often includes casein peptone if strictly casein-derived) | Dairy-derived peptides, high-end fermentation | Milk/Casein |
3504.00.30.00 |
Peptones and their derivatives; other protein hydrolysates | Most common: Soy peptone, meat peptone, gelatin peptone | Soy, Meat, Gelatin |
3504.00.90.00 |
Peptones and derivatives, other | Non-standard or mixed-source peptones | Mixed/Other |
2936.27.00.00 |
Vitamins and their derivatives, purified (if fortified) | Pre-mixed media with vitamins | N/A |
3824.99.99.00 |
Prepared binders for foundry molds; chemical products n.e.c. | Unpurified hydrolysates with heavy impurities | Industrial |
🔍 Key Reminder:
- The vast majority of commercial Peptone (Soy Peptone, Meat Peptone) falls under3504.00.30.00or3504.00.90.00.
- If the product is specifically Casein Peptone, check with local customs if3502.20.00.00is more appropriate (often requires specific proof of casein origin).
- Do not classify under Chapter 21 (Food preparations) or Chapter 10 (Grains) unless it is a ready-to-eat nutritional supplement, which is rare for industrial Peptone.

🛠️ IV. Customs Clearance Practical Advice (实战避坑指南)
✅ 1. Preparation Checklist (Indispensable)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must list: Source (Soy/Casein/Meat), Nitrogen content, pH, Moisture |
| ✅ COA (Certificate of Analysis) | ✔️ | To prove it is a pure peptone, not a pre-mixed culture medium |
| ✅ Free Sale Certificate | ✔️ | From manufacturer or chamber of commerce |
| ✅ Safety Data Sheet (SDS) | ✔️ | Classify as non-hazardous (generally). If classified as hazardous, different rules apply |
| ✅ Commercial Invoice | ✔️ | Description: "Peptone, Soy Derived, Powder, for Fermentation Use" |
| ✅ Bill of Lading | ✔️ | Clear packaging details (bags, drums) |
✅ 2. Declaration Techniques (Key Tips)
🔥 "Source Matters, Purity Counts, Name Specific, Tax Saves!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Soy-based Peptone | 3504.00.30.00 "Soy Peptone" |
Calling it "Food Ingredient" → Chapter 21/19 (Higher risk) |
| Casein-based Peptone | 3504.00.30.00 or 3502.20.00.00 |
Calling it "Milk Powder" → Chapter 4 (Dairy tariffs apply) |
| Mixed Culture Media | 3004 or 3824 |
Calling it "Peptone" → Misclassification penalty |
| Industrial Enzyme Prep | 3507 |
Calling it "Peptone" → Wrong heading |
✅ 3. Special Circumstances Handling
| Situation | Handling Advice |
|---|---|
| OEM for Lab Research | Provide end-user lab info. If < $800, de minimis might apply (but check IEEPA restrictions). |
| Pharmaceutical Grade | May require FDA Prior Notice (if entering US). Ensure GMP compliance. |
| Animal Origin (Meat) | High Alert: Must have APHIS/USDA Import Permit. Check if the source country is approved for export to US. |
| Plant Origin (Soy) | Easier clearance. No animal health permit needed. |
🌍 V. Global Major Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate | Certification Requirements | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3504.00.30.00 |
~13.4% (CN Origin) | FDA Prior Notice | Check IEEPA status annually |
| 🇨🇳 China | 3504.00.30.00 |
8% | No special | Common import for fermentation |
| 🇪🇺 EU | 3504.00.30.00 |
6.5% | REACH Registration | REACH compliance is critical |
| 🇦🇺 Australia | 3504.00.30.00 |
5% | APVMA (if agro) | Generally low tariff |
| 🇯🇵 Japan | 3504.00.30.00 |
7.5% | JECFA Compliance | High purity standards |
📌 Conclusion:
- USA: Tariff is moderate but IEEPA adds 10%. Animal-derived peptone requires USDA permits.
- EU: REACH registration is the biggest hurdle for chemical imports.
- China: Stable import hub, lower base tariff.
📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Error 1: Declaring Meat Peptone without USDA/APHIS permit
👉 Consequence: Cargo seized or returned. US strict on animal protein imports.
❌ Error 2: Calling Pre-mixed Culture Media "Peptone"
👉 Consequence: Misclassification. Media may fall under 3004 (Pharmaceutical) or 3824, with different duties.
❌ Error 3: Ignoring REACH in EU shipments
👉 Consequence: Customs hold at EU border. No REACH registration = No entry.
❌ Error 4: Vague Description "Enzyme Substrate"
👉 Consequence: Customs inspection delay. Specify "Peptone for Microbial Fermentation".
✅ Correct Practice:
"Peptone, Soy-derived, Powder, Nitrogen Content 16%, for Bacterial Culture Media, NOT for Human Consumption, Manufacturer: [Name]"
🎯 VII. Conclusion: Professional Declaration, Safe Clearance!
🎯 Remember the Mantra:
🔹 "Soy Peptone: 3504, Base Tax Low, IEEPA 10%."
🔹 "Meat Peptone: USDA Permit, Or It Won't Go."
🔹 "EU Shipment: REACH First, Then Ship."
📌 Pro Tip:
If your Peptone is produced in Vietnam, Thailand, or India, you may avoid IEEPA 10% additional tariff.
Suggestion: Consider supply chain diversification to Third Countries for US-bound goods to save 10%.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
