Cellulose Acetate Protective Film

🎬 Cellulose Acetate Protective Film (醋酸纤维素保护膜)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Tariff Breakdown | Strategic Compliance Strategy
📌 I. Product Definition: What is "Cellulose Acetate Protective Film"?

Cellulose Acetate (CA) film is a transparent, biodegradable plastic film derived from natural cellulose (wood pulp or cotton). In international trade, it is primarily used for protective coatings, packaging, optical layers, and industrial shielding.

Unlike standard Polyethylene (PE) or Polypropylene (PP) films, CA film has specific physical properties: * High Clarity & Gloss: Superior optical performance. * Gas Barrier: Better oxygen barrier than PE/PP. * Flammability: More flammable than other thermoplastics. * Sensitivity: Sensitive to humidity and solvents.

⚠️ Critical Classification Distinction:
The HS Code depends heavily on Thickness and Form (Sheet vs. Roll/Film) and whether it is in a Primary/Unprocessed Form or a Finished Product Form.
- If it is a raw/semi-finished film intended for further processing → Often 3912 or 3920.
- If it is a specific thickness (<0.076mm) → Special subheadings apply.
- If it is a reconstituted fiber film → 3921.

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

🔍 Key Classification Logic:
- 3912: Chapter 39, Heading 12 refers to "Cellulose and its chemical derivatives... in primary forms." This is for unworked or simply worked products.
- 3920: Chapter 39, Heading 20 refers to "Other plates, sheets, film, foil and strip..." This is for processed products with specific physical dimensions (like thickness limits).
- 3921: Chapter 39, Heading 21 refers to "Other plates, sheets, film, foil and strip..." specifically for reconstituted materials.
- Why 5 different codes? Because US Customs (CBP) distinguishes based on manufacturing stage and physical dimensions (especially the 0.076mm threshold).

💰 III. 2026 Tariff Rate Analysis (Detailed Breakdown)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: Post-2025 Import Cycles
✅ Warning: All listed codes attract Significant Additional Tariffs.

🎯 1. 3912.11.00.00 & 3912.12.00.00 — Primary Forms / Sheets

• Summary: Raw or semi-finished cellulose acetate in sheet form.

📌 Explanation:
- The 5.6% is the standard Most Favored Nation (MFN) rate for primary cellulose derivatives.
- The 25% is the standard Section 301 tariff for Chinese origin goods.
- The 10% is a specific "Section 122" tariff (often related to trade remedies or specific administrative provisions).
- Total: 40.6%. This is a high-cost item for US importers.

🎯 2. 3920.73.00.00 — Standard Films/Sheets

• Summary: Classified generally as plates, sheets, or foil.

📌 Explanation:
- Slightly lower base duty (2.9%) compared to 3912 codes.
- Total: 37.9%. Still very high, but ~2.7% cheaper than the 3912 codes.

🎯 3. 3920.79.10.00 — Ultra-Thin Films (≤ 0.076 mm)

• Summary: Specifically for films/thickness ≤ 0.076 mm.

📌 Explanation:
- The 6.2% base duty reflects the premium or specific classification for thin films.
- Total: 41.2%. This is the highest duty among the provided options.
- Risk: If you declare a 0.08mm film as 0.07mm to try for a different code, it will be rejected.

🎯 4. 3921.14.00.00 — Regenerated Fiber Films

• Summary: Films made from regenerated cellulose fibers.

📌 Explanation:
- 41.5% is the most expensive option.
- Only use this if the film is explicitly certified as being made from regenerated fibers (e.g., rayon-based). If it’s pure cellulose acetate from wood pulp, this may be misclassified.

🛠️ IV. Customs Clearance Practical Advice

✅ 1. Documentation Checklist (Must-Haves)

✅ 2. Classification Strategy (Key Decision Points)

🔥 Golden Rule:
"Thickness Defines Subheading, Composition Defines Heading."
- If thickness ≤ 0.076mm → Look at 3920.79.10.
- If thickness > 0.076mm → Look at 3920.73 or 3912.
- If it’s a raw chemical product → Look at 3912.

✅ 3. Pitfalls to Avoid

🌍 V. Global Market Comparison (2026)

📌 Conclusion:
The US market is exceptionally expensive for Chinese-origin Cellulose Acetate Films due to the cumulative effect of Base + 301 + 122 tariffs.
- Strategy: Consider sourcing from Vietnam, Thailand, or EU if possible to avoid Section 301/122.
- Alternatively: Optimize supply chain to use 3920.73.00.00 (37.9%) instead of 3912/3921 codes if product form allows.

📌 VI. Final Recommendation

1. Verify Thickness: If your film is ≤ 0.076mm, you are stuck with 41.2%. If it is > 0.076mm, aim for 3920.73.00.00 (37.9%).
2. Confirm Origin: Ensure the Certificate of Origin correctly states "China" if applicable. If not, tariffs drop significantly.
3. Pre-Ruling: For large shipments, apply for a CBP Advance Ruling to lock in the HS Code and avoid disputes.
4. Cost Calculation: Always budget for ~38-41% duty on CIF value for US imports.
