💄 Eyelash Extension Glue + Crystal Liquid: The Ultimate Import & Customs Guide (2026)

🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy

Eyelash extension glue and crystal liquids (often used as sealers or top coats for lash extensions) are categorized under chemical preparations. Their customs classification depends strictly on their composition (animal-based vs. polymer-based) and packaging size (retail vs. bulk).

⚠️ Key Distinction:
- If the product is Animal-based glue (e.g., Casein) or generic prepared glue in retail packs ≤1kg → 3506.10.10.00
- If the product is Polymer-based adhesive (synthetic) for display screens (unlikely for lashes) → 3506.91.10.00
- If the product is a Painter’s Filling/Mastic/Caulking (unlikely for cosmetic use) → 3214.10.00.90 or 3214.10.00.10

📦 II. HS Code Classification Details (2026 Latest Authority Mapping)

🔍 Critical Warning:
- Do NOT misclassify cosmetic eyelash glue as "Caulking" (3214) or "Painter's Filling" (3214) to save taxes. This is smuggling/misdeclaration and will result in severe penalties, seizure, and blacklisting. - Correct Classification: Most synthetic eyelash glues are polymer-based adhesives. However, the specific subheading 3506.91.10.00 is narrowly defined for display screen adhesives.
- General Rule: If not specified elsewhere, prepared adhesives fall under 3506. For retail ≤1kg, 3506.10.10.00 (Animal/Casein) is a common catch-all if synthetic options aren't explicitly listed in the provided data. Note: Synthetic adhesives may fall under other 3506 subheadings not listed here, but based on the provided DATA, 3506.10.10.00 is the primary retail glue entry.

💰 III. 2026 Tariff Rate Breakdown (Including Additional Taxes)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (including subsequent imports)

🎯 1. 3506.10.10.00 —— Animal Glue (Including Casein Glue)

📌 Explanation:
- Eyelash glues containing animal proteins, casein, or similar biological adhesives packed for retail sale (≤1kg) fall here.
- Many "natural" or "professional" lash glues use casein-based formulas for strong bonding.
- 31.5% is a significant cost that must be factored into your FOB pricing.

🎯 2. 3506.91.10.00 —— Polymer-Based Adhesives (Display Screen Type)

📌 Explanation:
- This code is specifically for optically clear adhesives used in flat panel displays and touch screens.
- Do NOT use this code for eyelash glue unless it is explicitly manufactured for display screen assembly. Using this for cosmetics is misdeclaration.
- Even if you misdeclare it, the 25% tax still applies, so there is no tax saving benefit, only legal risk.

❌ 3. 3214.10.00.90 & 3214.10.00.10 —— Painters’ Fillings / Caulking Compounds

📌 Explanation:
- These codes are for construction materials (painter’s fillings, caulking, glazier’s putty).
- ABSOLUTELY DO NOT USE for cosmetic eyelash glue.
- If caught misdeclaring cosmetic products as construction materials, you face:
- Seizure of goods
- Civil Penalties (up to 3x the value of the goods)
- Criminal Charges for customs fraud
- Import ban

✅ 2. Declaration Strategy (Key Mnemonics)

🔥 "Be Honest, Be Specific, Avoid Construction Codes!"

📌 Note on Crystal Liquid:
- If the "Crystal Liquid" is a non-adhesive sealer/top coat (e.g., acrylic-based sealer), it may fall under cosmetics (Chapter 33) or prepared resin preparations.
- However, based on the provided DATA, the closest non-adhesive construction item is 3214. BUT, using 3214 for cosmetic sealers is highly risky and likely incorrect.
- Recommendation: If the crystal liquid is a cosmetic product, consult a customs broker for Chapter 33 codes (e.g., 3304.99.00.00). The provided DATA does not include Chapter 33, so do not force-fit it into 3214.

✅ 3. Special Case Handling

🌍 V. Global Market Clearance Comparison (2026 Latest)

📌 Conclusion:
- USA imposes 31.5% on animal/casein-based lash glues due to Section 301 tariffs.
- Misclassification as construction materials (3214) is a critical error with no legitimate tax advantage and severe legal consequences.
- Crystal Liquids should be evaluated separately. If they are cosmetic sealers, they may fall under Chapter 33, not 3506 or 3214.

📌 VI. Common Errors & Pitfalls Guide (Lessons from Tears)

❌ Error 1: Declaring eyelash glue as "Caulking Compound" (3214.10.00.10) to avoid taxes.
👉 Consequence: Seizure, 3x penalty, and blacklisting. U.S. Customs has specific databases for cosmetic chemicals. They know glue is not caulk.

❌ Error 2: Declaring synthetic polymer lash glue as 3506.91.10.00 (Display Adhesive).
👉 Consequence: Audit and reclassification. Even if the tax is similar (25% vs 31.5%), the description mismatch triggers red flags.

❌ Error 3: Ignoring FDA requirements for cosmetic products.
👉 Consequence: Detention at border. Even if customs clears the HS Code, FDA may reject the shipment for lack of registration or unsafe ingredients.

✅ Correct Approach:

"Lash Extension Adhesive, Casein-Based, Synthetic Polymer Free, Retail Package 10g, FDA Compliant"

🎯 VII. Conclusion: Professional Clearance, Save Time, Save Money!

🎯 Remember the Mantras:

🔹 "No Caulking, No Painter’s Filling for Lashes!"
🔹 "3506.10.10.00 for Animal Glue, 31.5% Tax is Real!"
🔹 "Crystal Liquid? Check Chapter 33, Not 3214!"
🔹 "FDA Compliance is as Important as HS Code!"

📌 Pro Tip:
If your eyelash glue is 100% synthetic and not animal-based, consult a customs broker for other 3506 subheadings not listed in the provided data. The provided data is limited, and synthetic adhesives may have different rates. Do not force-fit into 3506.10.10.00 if it’s not animal/casein.

📣 Immediate Action:

📞 Consult a Licensed Customs Broker to confirm the exact HS Code for your specific formulation.
🚀 Ensure FDA Registration before shipping.
