βοΈ POM Resin Granules (Polyoxymethylene / Acetal Resin)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
π I. Product Definition & Classification: Do You Really Understand "POM Granules"?
POM (Polyoxymethylene), commonly known as Acetal Resin, is a high-performance engineering thermoplastic. In international trade, it is classified under Chapter 39 (Plastics and Articles Thereof). The critical distinction lies in identifying the specific chemical family within the "Polyacetals" category.
Polyacetals (POM): Specifically refers to homopolyacetal or copolyacetal resins. These are high-strength, rigid plastics often used for gears, bearings, and precision parts. Other Polyethers/Epoxides: Other plastic resins that do not fall under the strict definition of polyacetals.
β οΈ Key Distinction Point:
- If the product is strictly POM (Polyoxymethylene/Acetal) β It falls under HS Code 3907.10.00.00.
- If the product is misidentified or belongs to a different polyether group (not POM) β It may fall under HS Code 3907.29.00.00 (Other polyethers).
- Crucial Note: POM is chemically distinct. Do not confuse it with generic "polyethers" if it is indeed POM. However, if customs questions the classification or if the product is a different type of polyether, the higher tariff code applies.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Tax Rate (China to US) |
|---|---|---|---|
3907.10.00.00 |
Polyacetals (including POM/Acetal Resin) | POM Granules, Acetal Homopolymer/Copolymer | 0.0% (Base + Surtax) |
3907.29.00.00 |
Other Polyethers (Non-POM) | Epoxide resins, other polyethers not specified elsewhere | 31.5% (Base 6.5% + Surtax 25%) |
π Key Reminder:
- POM Granules are specifically classified as Polyacetals under HS Code 3907.10.00.00.
- Misclassifying POM as "Other Polyethers" (3907.29.00.00) will result in a 31.5% total tax rate, which is a costly error.
- Ensure your technical data sheet explicitly states "Polyoxymethylene (POM)" or "Acetal" to support the3907.10classification.

β 2. Declaration Tips (Key Mantras)
π₯ βSpecify POM, Not Plastic! Clear Classification, Zero Duty!β
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| POM Granules (Acetal) | 3907.10.00.00 + "Polyoxymethylene Resin" |
Declare as "Plastic Pellets" β Risk of reclassification to 3907.29 (31.5%) |
| POM Granules + Additives | 3907.10.00.00 (if additives < critical %) |
Declare as "Composite Plastic" β Potential different classification |
| Other Polyethers (e.g., Epoxy) | 3907.29.00.00 |
Claim it's POM to avoid tax β Fraud Risk! |
π Warning:
- Do not use generic terms like "Plastic Granules" or "Raw Material."
- Do use specific chemical names: "Polyoxymethylene (POM)" or "Acetal Resin."
- If the product contains fillers (e.g., glass fiber), check if it still qualifies as "Polyacetals in primary forms." If yes,3907.10may still apply; if not, it may fall under a different subheading. Consult a customs broker for filled grades.
β 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| Filled POM (e.g., 20% Glass Fiber) | Verify if it remains "Polyacetals." If yes, 3907.10 applies. If not, it may fall under 3907.99 or other. Check specific tariff notes. |
| Recycled POM | Recycled plastics may have different classification. Ensure "Primary Forms" criteria are met. |
| Sample Shipments | Even for samples, declare accurate HS Code. Tax is 0% for POM, so no issue. But misclassification can lead to penalties. |
| Bulk Container Load | Ensure MSDS/SDS is provided. Customs may require chemical analysis to confirm POM identity. |

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