📦 Sealing Films (封缄膜)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Logistics Strategy
📌 I. Product Definition & Classification: What Exactly is "Sealing Film"?
"Sealing Film" (封缄膜) is a broad term in international trade, generally referring to plastic or aluminum foil films used to close, seal, or package containers, bags, or goods. Because the material (Plastic vs. Aluminum) and the specific function (Self-adhesive vs. Non-adhesive) vary significantly, these products fall into different HS Code categories with vastly different tax liabilities.
⚠️ Key Distinction Point:
- If the material is Aluminum Foil (even if thin) → Goes to Chapter 76 (Aluminum).
- If the material is Plastic and used as a Packaging/Container → Goes to Chapter 39 (Plastics).
- If the material is Plastic and is Self-Adhesive (like tape) → Goes to Chapter 39 but under a different subheading.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, here are the 5 most likely HS Codes for "Sealing Films" and why they are classified this way:
| HS Code | Product Description | Material/Logic | Why It Fits "Sealing Film" |
|---|---|---|---|
7607.19.60.00 |
Aluminum Foil (Other) | Aluminum or Plastic Foil | Classified as "Foil class." Fits if the film is primarily aluminum foil or plastic foil without a backing. |
3923.90.00.80 |
Plastic Sealing/Stopping Goods (Other) | Plastic | Fits "Plastic stoppers, caps, lids, and other sealing devices." Used for plastic plugs/caps or generic sealing items. |
3919.10.20.55 |
Self-Adhesive Plastic Films | Plastic (Self-Adhesive) | Fits flat/plastic film that is self-adhesive (sticky). Like sealing tape or adhesive seals. |
7607.19.30.00 |
Aluminum Foil for Sealing | Plastic or Aluminum | Specifically for plastic or aluminum foil used for sealing. Fits the "Other" category under sealing materials. |
3923.10.90.00 |
Plastic Films for Packaging | Plastic (Packaging) | Fits plastic films/sheets used for packaging or transporting goods. Generic plastic sealing bags/films. |
🔍 Key Takeaway:
- Aluminum vs. Plastic: This is the biggest split. If it's shiny/metallic, check 7607. If it's clear/colored plastic, check 3923 or 3919.
- Adhesive vs. Non-Adhesive: If it sticks to itself, it might be 3919 (Self-adhesive). If it's just a barrier, it might be 3923 (Packaging) or 7607 (Foil).

🛠️ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
✅ 1. Preparation Checklist (Missing Docs = Delay)
| Document | Required | Notes |
|---|---|---|
| ✅ Product Spec Sheet | ✔️ | Must specify: Material (Plastic vs. Aluminum), Thickness, Adhesive Type. |
| ✅ Product Photos | ✔️ | Clear images showing if it’s shiny (Aluminum) or transparent (Plastic). |
| ✅ Commercial Invoice | ✔️ | Use precise description: "Aluminum Foil Sealing Film" or "Plastic Packaging Film." |
| ✅ Material Certificate | ✔️ | Proof of material composition (e.g., "100% Aluminum" vs. "PET Plastic"). |
| ✅ Packing List | ✔️ | Ensure weight/volume matches invoice. |
✅ 2. Declaration Tips (Key Mantra)
🔥 “Material First, Function Second! Aluminum 13%, Plastic 38%+!”
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| Aluminum Foil Seal | 7607.19.60.00 or 7607.19.30.00 |
Declare as "Plastic Film" → Risk of reclassification & penalty. |
| Plastic Self-Sticky Tape | 3919.10.20.55 |
Declare as "Packaging Film" → Under-declare tax (38% vs 40.8%). |
| Plastic Sealing Bag | 3923.10.90.00 |
Declare as "Aluminum Foil" → Customs will test material → Fine. |
| Plastic Cap/Plug | 3923.90.00.80 |
Declare as "Film" → Wrong category. |
✅ 3. Special Case Handling
| Scenario | Handling Advice |
|---|---|
| Hybrid Materials (e.g., Plastic-Coated Aluminum) | Declare as Aluminum if aluminum is the dominant feature (7607). Otherwise, plastic. |
| Composite Films (Plastic + Foil) | If >50% aluminum by weight, try 7607. If not, 3923. |
| OEM/Custom Seals | Provide design specs to prove it’s not a standard "tape" but a "sealing device." |

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
