🚀 Wide Width Film for Aerospace Applications
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Clearance Strategy
📌 I. Product Definition & Classification: What is "Wide Width Film for Aerospace"?
Wide width films for aerospace are high-performance plastic films used in critical aviation and space applications, such as spacecraft thermal insulation, radar covers, interior cabin lining, and protective packaging for sensitive components. In international trade, these products are primarily classified under Chapter 39 (Plastics and Articles Thereof).
The classification depends heavily on two factors: 1. Form: Is it self-adhesive (sticky back)? 2. Material: Is it polyethylene (PE), polypropylene (PP), or another unspecified plastic?
⚠️ Key Distinction:
- If the film has an adhesive layer applied (for bonding/insulation) → Self-adhesive Plastic Films (3919)
- If the film is non-adhesive (bare film) → Non-Adhesive Plastic Films (3920 or 3921)
- Aerospace Context: High-value aerospace films are often specialized. If the material is specific (e.g., PE/PP), it goes to 3921.19. If it's a "catch-all" plastic or unspecified, it may fall under general headings like 3919.90 or 3920.99.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Reference)
| HS Code | Product Description | Application Scenario | Adhesive? |
|---|---|---|---|
3919.90.50.60 |
Wide-width plastic films, self-adhesive, other (Catch-all) | Specialized aerospace insulation, adhesive backing films | ✅ Yes |
3920.99.20.00 |
Wide-width plastic films, non-adhesive, other plastics | Bare flexible plastic films for general aerospace use | ❌ No |
3919.90.50.40 |
Wide-width plastic films, self-adhesive, other | Standard self-adhesive plastic tapes/films | ✅ Yes |
3921.90.50.50 |
Plastic films, non-adhesive, other (Material unspecified) | High-performance plastic films where material is not specified | ❌ No |
3921.19.00.10 |
Wide-width plastic films, non-adhesive, PE or PP | Films made of Polyethylene or Polypropylene | ❌ No |
🔍 Key Reminder:
- Self-adhesive vs. Non-adhesive: This is the primary split. If the film sticks by itself, it’s 3919. If it doesn’t, it’s 3920 or 3921. - Material Specificity: If you know it’s PE or PP, use 3921.19. If it’s a complex composite or unspecified, use 3921.90 or 3920.99.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Document Checklist (Required)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Spec Sheet | ✔️ | Must include width, thickness, material composition (PE, PP, PVC, etc.), and adhesive type (if any). |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | Required for chemical/plastic products. |
| ✅ Product Photos (Label & Bulk) | ✔️ | Clear images showing roll width and any adhesive backing. |
| ✅ Commercial Invoice | ✔️ | Must accurately describe the item as "Plastic Film" or "Adhesive Film" with HS Code. |
| ✅ Packing List | ✔️ | Details roll weight, diameter, and packaging type. |
| ✅ Certificate of Origin (CO) | ✔️ | If originating from other countries (e.g., Vietnam), may apply for exemptions. |
✅ 2. Declaration Tips (Key Rules)
🔥 "Adhesive Goes to 3919, Non-Adhesive to 3920/21. Material Matters!"
| Scenario | Correct HS Code | Wrong Action |
|---|---|---|
| Film has adhesive backing | 3919.90.50.xx |
Report as 3920 → Misclassification Risk |
| Film is non-adhesive, PE/PP | 3921.19.00.10 |
Report as 3920.99 → Higher Base Rate? |
| Film is non-adhesive, other plastic | 3920.99.20.00 or 3921.90.50.50 |
Vague description → Customs Delay |
| Roll width > 20cm | All above codes apply | Report as "Small Strip" → Penalty |
✅ 3. Special Cases Handling
| Scenario | Handling Advice |
|---|---|
| Aerospace Grade Specialty Film | Provide test reports (thermal resistance, conductivity) to justify specific material composition. |
| Composite Films | If multi-layer, classify based on the principal material. If unknown, use "Other" codes (3920.99 or 3921.90). |
| Sample Shipments | Even for samples, declare correctly. Do not use "Gift" or "Sample" to avoid customs scrutiny. |
| OEM Custom Films | Provide customer drawings/specs to prove specific material composition. |
🌍 V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (CN Origin) | Certification Required | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3920.99.20.00 or 3919.90.50.60 |
39.2% - 41.5% | No specific CE, but RoHS recommended | High tariffs due to Section 301 & 122 |
| 🇨🇳 China | 3920.99.20.00 |
5% - 8% | CNCA | No additional surcharges |
| 🇪🇺 EU | 3920.99.20 |
6.5% - 7.5% | REACH | No Section 301 equivalent |
| 🇯🇵 Japan | 3920.99.00 |
6% - 8% | JIS | No major surcharges |
| 🇰🇷 South Korea | 3920.99.90 |
6% - 8% | KC | FTA may apply if originating in ASEAN |
📌 Conclusion:
- USA has the highest cost due to combined Section 301 (25%) and Section 122 (10%) tariffs. - EU and Asia-Pacific markets have significantly lower tariffs. Consider supply chain diversification if targeting the US market.
📌 VI. Common Errors & Pitfalls (Blood Lessons)
❌ Error 1: Declaring "Adhesive Film" as "Non-Adhesive Film" (3920)
👉 Consequence: Customs may reclassify and charge higher base tariff or impose penalties for misdeclaration.
❌ Error 2: Not specifying material (e.g., just "Plastic Film")
👉 Consequence: Customs will assign the most restrictive code possible, potentially 3921.19 (6.5% base) or even 9001 if considered optical. Always specify PE, PP, PVC, PET, etc.
❌ Error 3: Ignoring Section 122 (10%)
👉 Consequence: Unexpected cost increase of 10% on top of Section 301. Total burden is ~40%, not just 25%.
❌ Error 4: Using De Minimis for small rolls
👉 Consequence: De Minimis exemption does NOT apply to these HS codes (denied). Even small shipments must pay full tariff.
✅ Correct Practice:
"Wide Width Plastic Film, PE Material, Non-Adhesive, Aerospace Grade, Width 1.5m, Coated with Silane"
🎯 VII. Conclusion: Professional Declaration, Cost Control, Efficiency!
🎯 Remember the Mantra:
🔹 "Adhesive = 3919, Non-Adhesive = 3920/21. Check Material! Check Width!"
🔹 "USA Tariff is ~40%, Don't Forget Section 122 + 301. De Minimis is OFF!"
📌 Pro Tip:
If your film originates from Vietnam, Mexico, Thailand, or Malaysia, you may apply for IEEPA Exemptions or FTAs to reduce tariffs significantly.
Recommend Advance Ruling (Pre-classification) with US Customs (CBP) for high-value aerospace contracts to avoid clearance delays.
📣 Immediate Action:

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
