📦 Metalized PET Biaxially Oriented Film (BOPET)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Metalized PET BOPET"?

Metalized PET Biaxially Oriented Film (often referred to as BOPET) is a high-performance plastic film. It starts with Polyethylene Terephthalate (PET) resin, which is extruded and then stretched in both machine and transverse directions (biaxially oriented) to enhance strength, clarity, and thermal stability. Finally, a thin layer of aluminum is vacuum-deposited onto the surface to create a reflective, barrier-like finish.

In international trade, this product is classified primarily under Chapter 39 (Plastics and Articles Thereof), specifically as Plates, Sheets, Film, Foil, and Strip.

⚠️ Key Distinction Points for Classification:
1. Metallization Status: Is the film already metallized (silver/shiny side) or unmetallized (transparent/color)?
- Metallized: Generally falls under 3920.62 (Polyesters, other plates, sheets, film, foil).
- Unmetallized/Functional: May fall under 3921.90 (Other plates, sheets, film, if it has special surface treatment or functional properties not covered in 3920).
2. Form & Application: Is it for packaging, electronics, or general use?
- Packaging/General: 3920 series is most common for basic metallized films.
- Specialty/Composite: If it has additional layers or specific functional coatings beyond simple metallization, it might be scrutinized under 3921.

🔍 Critical Note:
- 3920.62 is the standard heading for metallized polyester films.
- 3921.90 is used when the film has undergone specific chemical or physical treatments that give it properties beyond standard polyester film (e.g., high-barrier coatings, anti-static layers integrated with metallization).
- Misclassification Risk: Declaring a simple metallized PET film as 3921 may trigger海关 (Customs) inquiries for being "incorrectly declared." Conversely, declaring a highly functional composite film as 3920.62 might miss additional regulatory requirements.

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

Based on the provided data for Metalized PET BOPET, here are the relevant HS Codes, their summaries, and tax implications.

🔍 Key Insight:
- 3920.62.00.20 and 3920.62.00.50 are the most common classifications for standard metalized PET BOPET.
- 3921.90 codes are reserved for specialty PET films where the "metalization" is part of a more complex functional structure, or where the film is not primarily defined by its metallization but by other properties.
- Tax Difference: Most codes show 39.2%, but 3921.90.50.50 shows 39.8% due to a slightly higher base tariff (4.8% vs 4.2%).

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges & Policy Add-ons)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: Ongoing (2025/2026 Tariff Structure)

🎯 1. 3920.62.00.20 & 3920.62.00.50 — Standard Metallized PET Film

📌 Explanation:
- The 4.2% is the standard base duty for PET films.
- The +25% is the significant Section 301 tariff, which heavily impacts Chinese-origin plastics.
- The +10% is the Section 122 tariff, which applies to certain plastic articles imported in large volumes.
- Total: 39.2%. This is a high-cost item for importers.

🎯 2. 3921.90.50.50 — Specialty PET Film

📌 Note:
- The 0.6% difference (39.8% vs 39.2%) comes from the 0.6% higher base rate (4.8% vs 4.2%).
- If your film is a standard metallized BOPET, avoid 3921.90.50.50 unless it has special functional coatings (e.g., anti-fog, anti-static, high-barrier) that justify a different subheading. Otherwise, 3920.62 is more accurate and slightly cheaper.

🎯 3. 3921.90.40.90 — Other PET Films

📌 Note:
- This code is for non-metallized or specialty non-metallized PET films.
- If your product is metalized, do not use this code unless the metallization is incidental and the primary function is something else (e.g., a composite material where PET is just one layer).

🛠️ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)

✅ 1. Documentation Checklist (Mandatory)

✅ 2. Declaration Tips (Key Mnemonics)

🔥 "Metallized = 3920, Special Function = 3921. Be Precise!"

⚠️ Critical:
- 3920.62 is ONLY for PET films.
- If the film is not polyester (e.g., OPP, BOPP, PVC), it will be wrong.
- BOPET is always PET. So 3920.62 is the safest bet for standard metalized BOPET.

✅ 3. Special Cases

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- USA is the most expensive market due to 39.2% total duty.
- China, EU, UK, Australia are significantly cheaper.
- Strategy: If exporting to the US, consider pricing adjustments or supply chain diversification (e.g., third-country processing) to mitigate tariff impact.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring as "Plastic Sheet" (Generic)
👉 Result: Customs flags for inaccuracy. Delays and fines.

❌ Mistake 2: Using 3921 for Standard Metallized Film
👉 Result: Over-complication, potential audit. Stick to 3920.62 for standard metalized BOPET.

❌ Mistake 3: Ignoring Section 122 Surcharge
👉 Result: Underpayment of duty by 10%. Seizure or penalty.

❌ Mistake 4: Not proving Metallization
👉 Result: If customs suspects it’s unmetallized, they may classify it differently. Photos are key.

✅ Correct Practice:

"Metallized PET Film, Biaxially Oriented, 12 Micron, Width 1200mm, for Packaging Use. Material: Polyethylene Terephthalate. Surface: Vacuum Metallized Aluminum."

🎯 VII. Conclusion: Precision Classification Saves Money

🎯 Remember Mnemonic:

🔹 "BOPET Metallized = 3920.62. Base 4.2%, Add 35% = 39.2%. No De Minimis!"
🔹 "Check for Special Functions. If Yes, Consider 3921. If No, Stick to 3920."
🔹 "USA Tariff is High. Plan Accordingly."

📌 Pro Tip:
- For US imports, calculate the Landed Cost including 39.2% duty.
- Consider HS Code Pre-Ruling from CBP (U.S. Customs and Border Protection) if the product is borderline between 3920.62 and 3921.90.
- Document everything: Keep samples, specs, and photos for at least 5 years.
