๐ญ Plastic Sausage Casing Flanges (Industrial Plastic Fittings)
๐ HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
๐ I. Product Definition: What Are "Plastic Flanges"?
Plastic Flanges are pipe fittings used to connect, isolate, control, or route plastic pipes in fluid or gas transmission systems. In the context of "Plastic Sausage Casing" or industrial plastic applications, these are typically plastic pipe components used for fluid management in food processing, chemical, or industrial piping networks.
In international trade, the classification hinges on two key factors: 1. Material: Primarily plastics (e.g., PVC, PP, PE). 2. Function/Form: Are they specific pipe fittings (part of a piping system) or general plastic articles (accessories/connectors)?
โ ๏ธ Critical Distinction:
- If the product is specifically designed as a pipe joint/connection element (ๆณๅ ฐ็ฎกไปถ) โ It falls under Chapter 3917 (Plastic Pipes/Fittings).
- If it is a general plastic connector, coupling, or accessory not strictly defined as a "pipe fitting" โ It may fall under Chapter 3926 (Other Plastic Articles).
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Application Scenario | Key Classification Logic |
|---|---|---|---|
3917.40.00.50 |
Plastic Flange Fittings, Plastic Material, Form: Flange Fittings | Standard industrial plastic pipe flanges | โ Classified as Plastic Pipe Fittings under Heading 3917 |
3926.90.25.00 |
Plastic Flange Fittings, Plastic Material, Other Plastic Articles | General plastic connectors, non-standard flanges | โ Classified as Other Plastic Articles under Heading 3926 |
3926.30.50.00 |
Plastic Flange Fittings, Plastic Material, Use: Connecting Parts | Plastic connecting accessories, couplings | โ Classified as Other Plastic Articles (Parts/Accessories) |
3917.40.00.95 |
Plastic Flange Fittings, Plastic Material, Form: Flange Fittings (Other) | Other plastic pipe flanges not elsewhere specified | โ Classified as Plastic Pipe Fittings under Heading 3917 |
๐ Key Reminder:
- Chapter 3917 applies to "Plastics tubing, pipes and hoses... fittings." This is the most accurate classification for standard flange fittings used in piping systems.
- Chapter 3926 applies to "Other articles of plastics." This is used when the item is a generic plastic connector or accessory not meeting the strict definition of a "pipe fitting."
๐ฐ III. 2026 Latest Tariff Rate Details (Including Surcharges & Policy Add-ons)
โ Applicable Country: United States (US)
โ Origin: China (CN)
โ Effective Date: 2025/2026 (Current Trade Rules)
๐ฏ 1. 3917.40.00.50 & 3917.40.00.95 โโ Plastic Pipe Fittings (Flanges)
These codes classify the product as a pipe fitting, attracting higher additional tariffs due to the "Section 301" and "Section 122" policies.
| Item | Content |
|---|---|
| Base Tariff | 5.3% (Ad Valorem) |
| Section 301 Surcharge | +25.0% (China-specific) |
| Section 122 Surcharge | +10.0% (Additional duty on specific plastic goods) |

- The 10% is an additional tariff under Section 122, often applied to specific industrial plastic components.
- Total 40.3% is a high-cost scenario. Accurate classification is vital to avoid overpayment or misclassification penalties.
๐ฏ 2. 3926.90.25.00 โโ Other Plastic Articles (General Flange Connectors)

- Risk: If CBP determines the item is a "flange fitting" (Chapter 3917), this classification may be challenged.
๐ ๏ธ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
โ 1. Required Documentation Checklist
| Document | Must Provide | Explanation |
|---|---|---|
| โ Product Specification Sheet | โ๏ธ | Detailed dimensions, material type (PVC/PP/PE), pressure rating |
| โ Photos (Clear) | โ๏ธ | Show flange shape, bolt holes, threading, and markings |
| โ Commercial Invoice | โ๏ธ | Clearly state "Plastic Flange Fittings" or "Plastic Connectors" |
| โ Packing List | โ๏ธ | Weight, volume, and number of pieces |
| โ Material Certificate | โ๏ธ | Proof of plastic type (e.g., PVC-U, PP-R) |
| โ Origin Certificate | โ๏ธ | If applicable for preferential treatment (not available for US-China in this case) |
โ 2. Declaration Tips (Key Mantra)
๐ฅ "Specify Material, Define Function, Choose Code Wisely!"
| Scenario | Correct Declaration | Risk if Incorrect |
|---|---|---|
| Standard Pipe Flange | 3917.40.00.50 / 3917.40.00.95 |
If misclassified as 3926, may face penalties for incorrect valuation |
| Generic Plastic Connector | 3926.90.25.00 |
If deemed a pipe fitting, 40.3% tax applies instead of 24% |
| Accessory/Bracket | 3926.30.50.00 |
If deemed a fitting, 40.3% tax applies instead of 22.8% |
๐ Best Practice:
- If the product is explicitly a flange for pipes, use 3917.
- If it is a multi-purpose plastic connector, consider 3926 for lower tax, but ensure the product description supports this (e.g., "Plastic Adapter," not "Flange Fitting").
โ 3. Special Cases
| Situation | Handling Advice |
|---|---|
| Mixed Shipment | Separate pipe fittings (3917) from general plastic accessories (3926) in declaration to optimize tax |
| OEM Custom Flanges | Provide design drawings to prove if it's a standard fitting or custom accessory |
| Food-Grade Plastic | Mention "Food-Grade" in description; may require FDA compliance documents |
| High-Pressure Flanges | Clearly state pressure rating; may require engineering certificates |
๐ V. Global Market Clearance Comparison (2026)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Note |
|---|---|---|---|---|
| ๐บ๐ธ USA | 3917.40.00.50 or 3926.90.25.00 |

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) โ Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) โ More specific grouping within the chapter
- Subheading (6 digits) โ Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) โ 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 โ The standard duty rate applied to WTO members
- General rate โ Applied to countries without trade agreements
- Trade remedy duties โ Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
