π΅ Theine Isolation from Black Tea Dust
π HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: What Exactly Is "Theine"?
"Theine" is an older, historical synonym for Caffeine (1,3,7-trimethylxanthine). Chemically and biologically, it is identical to caffeine. When isolated from black tea dust, it is a natural alkaloid derived from a vegetable origin.
In international trade, the classification depends heavily on the purity and the chemical form (free base vs. salt). However, the core principle remains: it is classified under Chapter 29 (Organic Chemicals) as an alkaloid.
β οΈ Key Distinction:
- If the product is pure Caffeine (Theine) (free base or salt) β It falls under 2939.30 (Caffeine and its salts).
- If the product is a crude extract containing caffeine but also other tea compounds β It may fall under 1302.19 (Vegetable saps and extracts).
- Most isolated "Theine" for pharmaceutical or industrial use is pure caffeine and is classified under 2939.30.00.00.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Alignment)
Based on the provided <DATA>, here are the relevant HS Codes for items related to Caffeine/Theine and Tea Extracts.
| HS Code | Product Description | Applicable Scenario | Tax Rate (Total) |
|---|---|---|---|
2939.30.00.00 |
Alkaloids: Caffeine and its salts | Pure isolated Theine/Caffeine (free base or hydrochloride, etc.) | 0.0% |
2939.79.00.00 |
Alkaloids: Other, of vegetal origin: Other | Other plant alkaloids (not caffeine, not cocaine, etc.) | 0.0% |
1302.19.91.40 |
Vegetable saps and extracts: Other | Crude tea extracts not further purified to pure alkaloids | 7.5% |
1302.19.41.40 |
Vegetable saps and extracts: Ginseng / Therapeutic | Specific therapeutic extracts (e.g., Ginseng, not standard tea) | 8.5% |
9027.89.80.30 |
Chemical analysis instruments | Equipment used to measure Theine content, not Theine itself | 25.0% |
9027.50.40.15 |
Chemical analysis instruments (Optical) | Spectrometers used in the process of isolation/verification | 25.0% |
π Critical Reminder:
- "Theine" = Caffeine. Customs authorities recognize this synonym. Do not use vague terms like "Tea Powder" if it is purified.
- Pure Theine (Caffeine) is explicitly listed in 2939.30.00.00 with a 0% total tax.
- Crude Tea Extracts (containing caffeine but also tannins, fibers, etc.) fall under 1302.19 with higher taxes (7.5%-8.5%).
- Misclassification Risk: Declaring pure Caffeine as "Tea Extract" (1302.19) may lead to overpayment of taxes (7.5% vs 0%). Conversely, declaring "Tea Extract" as "Caffeine" may trigger audit flags for false declaration.

π οΈ IV. Practical Clearance Advice (Expert Pitfall Avoidance Guide)
β 1. Documentation Checklist (Essential)
| Document | Must Provide | Explanation |
|---|---|---|
| β Certificate of Analysis (COA) | βοΈ | Must confirm Caffeine Theine content >99%. Distinguishes it from "Tea Extract". |
| β Product Name | βοΈ | Use "Caffeine (Theine), Pure" or "Caffeine Anhydrous". Avoid "Teine Powder" without clarification. |
| β Chemical Structure | βοΈ | 1,3,7-Trimethylxanthine. Proves it is an alkaloid under Chapter 29. |
| β Intended Use | βοΈ | Pharmaceutical, food additive, or industrial? Affects FDA requirements more than Customs. |
| β Certificate of Origin (CO) | βοΈ | To claim any potential FTAs (though none apply to US from China for this item). |
β 2. Declaration Strategy (Key Mantra)
π₯ "Pure Alkaloid, Chapter 29, 0% Tax. Crude Extract, Chapter 13, 7.5% Tax."
| Scenario | Correct Declaration | Error to Avoid |
|---|---|---|
| Pure Caffeine/Theine | 2939.30.00.00 - "Caffeine Anhydrous" |
Misdeclare as 1302.19 β Pay extra 7.5% unnecessarily. |
| Crude Tea Extract | 1302.19.91.40 - "Tea Extract" |
Misdeclare as 2939.30 β Risk penalty for false classification. |
| Caffeine Salts (e.g., Citrate) | 2939.30.00.00 - "Caffeine Citrate" |
Declare as "Vitamin Supplement" β Wrong chapter. |
β 3. Special Situations
| Situation | Handling Advice |
|---|---|
| FDA Regulation | Even with 0% tariff, Caffeine is regulated by FDA. Ensure compliance with 21 CFR for food/pharma additives. |
| Mixed Shipment | If Caffeine is mixed with other alkaloids, ensure the primary function/purity dictates Chapter 29. |
| Packaging | Ensure packaging is labeled as "Caffeine" for clear customs identification. |
π V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 2939.30.00.00 |
0% | FDA Compliance | No surtax on Caffeine. |
| π¨π³ China | 2939.30.00.00 |
~3.5% | N/A | Export duty may apply; check local export policies. |
| πͺπΊ EU | 2939.30.00.00 |

π Conclusion:
- The USA is the most tax-favorable market for Pure Caffeine/Theine (0% tariff).
- European and Japanese markets also offer low tariffs but have stringent safety certifications (REACH, EFSA, MHLW).
- Avoid Classifying as "Tea Extract" if the product is pure Caffeine to save on taxes and avoid unnecessary regulatory scrutiny under food/extract laws.
π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Declaring "Theine" as "Tea Leaves"
π Consequence: Wrong Chapter (2 vs 9/13), potential duty misassessment and customs delay.
β Error 2: Using "Natural Caffeine" vs "Synthetic Caffeine" without clarification
π Consequence: Both fall under 2939.30.00.00, but FDA may require different disclosures for source. Tariff is the same.
β Error 3: Ignoring FDA Regulations
π Consequence: 0% tariff doesn't mean free entry. FDA can detain shipments for lack of prior notice or safety documentation.
β Error 4: Misclassifying as "Food Supplement" directly
π Consequence: Customs looks at the chemical product, not the end-use. Declare the chemical (Caffeine), not the supplement form, unless it's a finished supplement.
β Correct Practice:
"Caffeine Anhydrous, 99% Purity, HPLC Grade, HS Code 2939.30.00.00, For Pharmaceutical Use"
π― VII. Conclusion: Professional Declaration, Save Time, Reduce Costs!
π― Remember the Mantra:
πΉ "Theine is Caffeine, Chapter 29, 0% Tax."
πΉ "Crude Extract is Chapter 13, 7.5% Tax."
πΉ "Pure Purity Dictates Classification."
π Pro Tip:
If your "Theine" is derived from Green Tea vs Black Tea, the HS Code is identical (2939.30.00.00) if it is pure Caffeine. The source affects FDA labeling but not Customs Tariff.
π£ Immediate Action:
π Verify Purity >99% β Use HS Code
2939.30.00.00β Enjoy 0% Tariff in the US.
π Ensure FDA Compliance to avoid post-clearance seizures.
β¨ Professional Clearance Starts with Precise Classification!
πΌ Every Percent Saved in Tariff is Pure Profit!

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) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β 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 β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
