🧪 Tartaric Acid (Acidum Tartaricum)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Tartaric Acid"?

Tartaric acid, a weak organic dicarboxylic acid found in many plants (especially grapes), is a versatile chemical raw material. In international trade, it is primarily classified as a specific organic chemical compound.

Key Identity: * Chemical Name: Tartaric Acid * HS Chapter: 29 (Organic Chemicals) * Specific Category: Carboxylic acids with alcohol function but without other oxygen function.

⚠️ Critical Distinction:
- If it is pure Tartaric Acid (a single compound) → It falls under HS 2918.12.00.00.
- If it is a mixture (e.g., mixed with other organic substances, binders, or inorganic compounds) → It may fall under HS 3824.99.29.00 or 3824.99.39.90 depending on composition.
- Do not confuse with general "organic compounds" (HS 2942) or "preparations" (HS 3824) unless the purity and definition strictly change.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)

Based on the provided DATA, here are the relevant HS Codes for Tartaric Acid and related chemical mixtures:

🔍 Key Insight:
- 2918.12.00.00 is the exclusive and correct code for pure Tartaric Acid.
- Codes under 2942 ("Other organic compounds") are incorrect for Tartaric Acid because Section XXIX (Chapter 29) provides a specific heading for carboxylic acids with alcohol functions (2918). Specific always overrides general.
- Codes under 3824 are only relevant if the product is a mixture (e.g., a cleaning solution or binder containing Tartaric Acid mixed with other substances). If it is pure, do NOT use 3824.

🌍 V. Global Market Comparison (2026)

📌 Conclusion:
- The USA imposes a 25% tariff on pure Tartaric Acid from China.
- EU and Japan are more tariff-friendly.
- If sourcing for the US market, consider supply chain diversification (e.g., sourcing from India or EU) to mitigate the 25% duty if volumes are high.

📌 VI. Common Errors & Pitfall Guide (Lessons Learned)

❌ Error 1: Declaring Tartaric Acid as "Other Organic Compounds" (2942.00.50.00) to avoid tariffs.
👉 Consequence: Customs will reclassify, impose 25% duty + penalties + interest.

❌ Error 2: Using CAS Number 8477-40-5 (wrong CAS) or omitting CAS.
👉 Consequence: Customs may hold shipment for inspection, causing delays.

❌ Error 3: Mixing Pure Tartaric Acid with other binders but declaring as pure acid.
👉 Consequence: Misclassification. If it’s a mixture, it might fall under 3824 with different tax rules.

❌ Error 4: Ignoring Section 301 List 4A applicability.
👉 Consequence: Underpayment of duties.

✅ Correct Practice:

"Tartaric Acid, Food Grade, CAS 77-93-6, 99.5% Purity, Crystalline Solid, HS 2918.12.00.00, Origin: China"

🎯 VII. Conclusion: Professional Declaration for Cost Control

🎯 Remember the Mantra:

🔹 "Pure Acid: 2918.12, Duty 25%. Mixture: 3824, Duty Varies. CAS 77-93-6 is Key!"
🔹 "Don't Guess 'Other', Be Specific. Avoid Penalties, Stay Compliant."

📌 Pro Tip:

If you are importing large volumes of Tartaric Acid to the US, consult a customs broker about Exclusions (if any are active for List 4A chemicals) or consider Bonded Warehousing to defer duty payment until final sale.
Pre-ruling is highly recommended for large shipments to ensure classification stability.

📣 Immediate Action:

📞 Contact your freight forwarder + Provide CAS 77-93-6 + Confirm Purity > 99%
