🧪 Polyoxymethylene (POM) - General Purpose
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 1. Product Definition and Classification: What Exactly is "General Purpose POM"?
Polyoxymethylene (POM), also known as Acetal or Delrin, is a high-performance engineering thermoplastic. It is renowned for its high stiffness, low friction, excellent dimensional stability, and superior resistance to solvents and fuels.
In international trade, POM is classified under Chapter 39 (Plastics and Articles Thereof). The specific HS Code depends on whether the material is in its primary form (raw material for processing) or in a specific finished form (like rods, sheets, or parts).
Key Distinction: - Primary Forms (Raw Material): Powders, granules, pellets, or preforms intended for molding/extrusion. These are classified under 3907. - Semi-Finished Forms (Rods, Sheets, Profiles): If the material has been shaped into specific semi-finished forms, it may fall under 3916-3926. - Finished Parts: If the POM has been molded into specific final products (e.g., gears, valves), it may fall under 8483 or 8484, etc., depending on the application.
⚠️ Critical Note for Customs:
Most shipments of "General Purpose POM" are raw materials (granules/powder). Therefore, the most common HS Code is 3907.10. However, always verify the physical state of the goods. If they are rods or sheets, they may be classified differently.
📦 2. HS Code Classification Details (2026 Latest Tariff Schedule)
| HS Code | Product Description | Application Scenario | Physical State |

3907.10.10.00 |
Polyacetals (POM) in Primary Forms | Raw plastic pellets/powder for injection molding | ✅ Granules/Powder |
3907.10.90.00 |
Other Polyacetals in Primary Forms | Alternative formats of raw POM | ✅ Granules/Powder |
3916.20.80.00 |
Monofilament, Rods, and Profiles of Plastics | Semi-finished rods, tubes, or profiles | ✅ Solid Shapes |
3920.62.00.00 |

🔍 Key Reminder:
- If you are importing raw plastic pellets (the most common form for "General Purpose POM"), use 3907.10.
- If you are importing pre-formed rods or sheets, use 3916 or 3920 series.
- Do not confuse POM with "Engineering Plastics" like PA (Nylon) or PC (Polycarbonate), which have different HS codes.

📌 6. Common Errors & Pitfall Avoidance Guide (Blood and Tears Lessons)
❌ Error 1: Declaring "POM" as "Plastic Bags" or "Plastic Toys"
👉 Consequence: Wrong HS Code, potential fraud investigation, fines!
❌ Error 2: Misdeclaring raw granules as "Finished Parts" to get a lower rate
👉 Consequence: Customs audit, seizure, back taxes + penalties!
❌ Error 3: Not providing MSDS for plastic granules
👉 Consequence: Port delay, additional testing costs!
❌ Error 4: Ignoring the 301 & IEEPA surcharges
👉 Consequence: Unexpected 22.8% tariff cost, eroding profit margins!
✅ Correct Practice:
"Polyoxymethylene (POM) Granules, Unfilled, White, for Injection Molding, HS Code: 3907.10.10.00, Origin: China, Tariff: 22.8%"
🎯 7. Conclusion: Professional Declaration Saves Time and Money!
🎯 Remember the Mantra:
🔹 "Raw POM: 3907, Semi-Finished: 3916/3920, Finished: 3926, Tax 22.8%-23.1%!"
🔹 "HS Code Determines Life, Tariff Differs by Points, Declaration Error Costs Thousands!"

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
