Section 301 tariffs. De minimis rules. HTS classification gray zones.
Importing molded pulp packaging to the US isn't complicated—if you know the right codes and the right paperwork. Get either wrong, and your landed cost can jump 25% overnight.
Molded pulp products fall into several HTS chapters. The wrong code = the wrong duty rate:
| HTS Code | Description | Base Duty Rate | Section 301 Tariff | **Total Duty** |
|---|---|---|---|---|
| 4823.70.0000 | Molded or pressed articles of paper pulp | 0% | 25% | **25%** |
| 4823.90.8600 | Other paper/cardboard articles (non-molded) | 0% | 0% *or* 25% | **0-25%** |
| 3923.90.0080 | Plastic packaging (wrong classification) | 3% | 25% | **28%** |
The key distinction:** 4823.70 covers "molded or pressed" articles. If your product is die-cut from flat sheet (not molded from wet pulp), it may fall under 4823.90 with potentially different duty treatment. **Clarify with your customs broker before the first shipment.
The Section 301 tariffs on Chinese imports remain in effect for List 3 goods, which includes HTS 4823.70 (molded pulp articles).
| Development | Status (July 2026) | Impact |
|---|---|---|
| List 3 (25% tariff) | Active | Applies to 4823.70 molded pulp |
| Exclusion process | Closed; no current exclusions for pulp packaging | No relief available |
| De minimis ($800 rule) | Active; under political scrutiny | Small shipments ≤$800 exempt from Section 301 |
| Potential changes | USTR review ongoing; no timeline | Monitor USTR Federal Register notices |
Practical impact: Budget for 25% duty on all molded pulp imports from China that exceed $800 in value per entry.
Under Section 321 (de minimis), shipments valued at $800 or less enter duty-free and Section 301-free.
| Scenario | Annual Volume | Shipment Strategy | Duty Savings |
|---|---|---|---|
| Amazon FBA small seller | 5,000 units/year | Split into daily $799 shipments | **$3,000-5,000/year** |
| Mid-size brand | 50,000 units/year | De minimis not practical | Pay duty; optimize elsewhere |
| Large brand | 250,000+ units/year | Container-level; negotiate duty drawback | Use duty drawback program |
Warning: CBP is increasingly scrutinizing de minimis splitting. If they determine you're artificially breaking shipments to avoid duties, penalties apply. Work with a qualified customs broker on compliant structuring.
| Document | Who Provides | Required For |
|---|---|---|
| Commercial Invoice | Supplier (YisenPulp) | All shipments |
| Packing List | Supplier | All shipments |
| Bill of Lading (ocean) / AWB (air) | Freight forwarder | All shipments |
| CBP Form 7501 (Entry Summary) | Customs broker | Formal entries (≥$2,500) |
| CBP Form 3461 (Entry/Immediate Delivery) | Customs broker | All entries |
| ISF (Importer Security Filing) | Importer or broker | Ocean shipments—**file 24h before loading** |
| FDA Prior Notice (if food-contact) | Importer or broker | Food-contact pulp packaging |
| Certificate of Origin | Supplier | Required for Section 301 duty assessment |
| Cost Line | Amount | Notes |
|---|---|---|
| FOB price (10K units × $0.25) | $2,500 | Ex-factory YisenPulp |
| Ocean freight (LCL, 2 CBM) | $380 | Shanghai → LA |
| Insurance (0.5% of CIF) | $14 | |
| CIF value | $2,894 | |
| US duty (25% Section 301 on CIF) | $724 | Applies to 4823.70 |
| Merchandise Processing Fee (0.3464%) | $10 | Min $29.66 for formal entries |
| Customs broker fee | $125 | One-time per entry |
| Drayage (port → warehouse) | $350 | LA area |
| **Total landed cost** | **$4,103** | |
| **Landed cost per unit** | **$0.41** | (+64% over FOB) |
Your takeaway: The $0.25/unit FOB price becomes $0.41/unit landed. Duties and logistics add 64%. Build this into your retail pricing from day one.
Q: Are molded pulp products from Vietnam subject to the same tariffs?
A: No. Section 301 applies only to Chinese-origin goods. Vietnam-origin molded pulp enters at 0% duty (MFN rate for HTS 4823.70) with no Section 301 surcharge. This is a key sourcing diversification strategy for 2026-2027.
Q: How do I prove "country of origin" if my pulp trays are molded in Vietnam but the fiber comes from China?
A: The "substantial transformation" test applies. If the Chinese fiber is transformed into a new product (molded tray) in Vietnam, Vietnam is the country of origin. The Certificate of Origin (Form B) is your evidence.
