🛍️ Four Layer Bag Liner: HS Code Classification & Customs Clearance Guide

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

📌 I. Product Definition & Classification: What is a "Four Layer Bag Liner"?

A Four Layer Bag Liner is typically an internal component used within rigid or semi-rigid packaging containers (such as tote bags, intermediate bulk containers (IBCs), or industrial sacks). Its primary function is to provide a barrier against moisture, contamination, or product leakage.

In international trade, the classification depends heavily on material composition and structural form: - Plastic Liners: If the liner is primarily made of polymer films (e.g., PE, PP, laminated plastics), it falls under Chapter 39. - Paper/Composite Liners: If the liner is made of paper, multi-layer paper, or paper-plastic composites, it falls under Chapter 48.

⚠️ Critical Distinction Point: - If the item is a plastic film/sheet used as a lining → Classify under Chapter 39. - If the item is a paper-based bag or liner → Classify under Chapter 48.

📦 II. HS Code Classification Details (Based on Provided Data)

🔍 Key Reminder: - If the liner is plastic but shaped like a pouch → 3923.29.00.00. - If the liner is plastic film not formed into a bag → 3921.90.19.50. - If the liner is paper-based → 4819.40.00.40 or 4819.40.00.20 (depending on layer structure).

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: 2025年11月10日起 (From Nov 10, 2025)

🎯 1. Plastic-Based Liners (3923.29.00.00, 3923.21.00.95)

📌 Explanation: - Base Duty 3%: Standard MFN rate for plastic sacks/bags. - Section 301 (25%): Additional tariff on Chinese goods under US Trade Act Section 301. - Section 122 (10%): Additional tariff under US Trade Act Section 122 (national emergency/import surge). - Total 38%: High cost factor. Must be factored into pricing strategy.

🎯 2. Plastic Film/Sheet Liners (3921.90.19.50)

📌 Note: - Plastic films/sheets not formed into bags have a slightly higher base duty (5.3%). - Same surcharges apply → Total 40.3%.

🎯 3. Paper-Based Liners (4819.40.00.40, 4819.40.00.20)

📌 Advantage: - Paper-based liners have 0% base duty, making them slightly cheaper than plastic film liners. - However, surcharges still apply → Total 35%. - Suitable for eco-friendly branding, but ensure material composition is clearly stated as paper/composite.

✅ 2. Declaration Strategy (Key Tips)

🔥 "Material First, Structure Second, Name Precise, Tax Minimized!"

✅ 3. Special Cases Handling

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion: - USA is the most expensive market for Chinese-made bag liners due to layered tariffs. - Plastic liners face higher total tax (38-40.3%) than paper liners (35%). - Consider supply chain diversification (e.g., Vietnam, Thailand) if targeting US market to avoid surcharges.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring plastic liners as "packaging materials" without specifying form.
👉 Result: Customs may classify under general packaging (higher tax) or request clarification → Delay.

❌ Mistake 2: Ignoring the "Section 122" 10% surcharge.
👉 Result: Underestimating landed cost by 10% → Margin erosion.

❌ Mistake 3: Using "bag" for film-like liners.
👉 Result: Incorrect HS code → Potential penalties for misdeclaration.

❌ Mistake 4: Assuming de minimis applies to small shipments.
👉 Result: No exemption for Chinese goods → Full tax liability.

✅ Correct Practice:

"4-Layer PE Plastic Bag Liner, Pouch Shape, For Industrial Sacks, Model XYZ, Compliant with FDA/REACH"

🎯 VII. Conclusion: Precise Classification, Efficient Customs Clearance

🎯 Remember:

🔹 "Material dictates Chapter, Shape dictates Subheading, Surcharges dictate Cost."
🔹 "Plastic = Ch39, Paper = Ch48, Surcharge = +35% on base."

📌 Pro Tip:

• If your liner is originating from Vietnam, Mexico, or Thailand, you may avoid Section 301 & 122 surcharges.
• Apply for Advance Ruling (Pre-classification) with US CBP to confirm HS Code and tax liability before shipment.
