What Are HS Codes for Vacuum Flask Parts?
HS codes classify vacuum flask parts for global trade duties and regulations. The Harmonized System (HS) standardizes product identification worldwide. Vacuum flask parts like lids and gaskets fall under specific codes based on material and function. In 2025, accurate HS code use prevents delays and fines in international shipping.
Primary HS Code 9617.00 for Vacuum Flask Components
HS code 9617.00 covers complete vacuum flasks and integral parts in 2025. This code applies to:
- Vacuum flask lids
- Outer protective casings
- Sealing mechanisms for insulation
Use this for assembled or key components in thermal containers.
HS Code 7010.90 for Glass Inners in Vacuum Flasks
Separate glass inners use HS code 7010.90 for 2025 shipments. This applies when glass parts ship independently from flasks. Key points:
- Glass bottles, flasks, jars
- Carboys, demijohns
- Not for complete vacuum flasks (use 9617.00)
Confirm separation status with customs rulings.
Plastic Lids: HS Code 3923.50 Explained
HS code 3923.50 handles plastic closures for vacuum flask parts. Ideal for:
- Plastic stoppers and caps
- Screw lids for flasks
- Non-metal closures
| Material | HS Code | Example |
|---|
| Plastic | 3923.50 | Flask lid |
| Glass inner | 7010.90 | Separate liner |
Metal Caps Under HS Code 8309.90
Metal stoppers and lids classify under HS code 8309.90 in 2025. Covers:
- Metal screw caps
- Crown corks, threaded bungs
- Base metal seals
Essential for durable vacuum flask hardware.
Thermal Sleeves and Covers: Material-Based HS Codes
HS codes for thermal sleeves depend on material for vacuum flask accessories.
- Textile: 6307.90 (made-up textile articles)
- Plastic: 3926.90 (plastic articles)
- Leather straps: 4205.00
2025 updates emphasize material accuracy per WCO guidelines.
Gaskets and Seals: 4016.93 vs 3926.90
Replacement gaskets for vacuum flasks use rubber or plastic HS codes. Breakdown:
- Rubber: 4016.93 (rubber gaskets)
- Plastic: 3926.90
- Other: Check composite rules
Avoid misclassification to prevent tariff errors.
2025 HS Code Changes for Vacuum Flask Parts
No major WCO HS revisions until 2027, but 2025 national updates apply. Key shifts:
- Enhanced sustainability material scrutiny
- Smart tech components evaluation
- Trade agreement tariff adjustments
Monitor country-specific extensions beyond 6-digit HS.
How to Find Correct HS Code for Vacuum Flask Parts
Step-by-step process ensures accurate HS code selection.
