๐ Cellulose Acetate Water Resistant Board
๐ HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Strategy
๐ I. Product Definition & Classification: Do You Really Understand "Cellulose Acetate Board"?
Cellulose Acetate Boards are high-precision plastic sheets made from cellulose acetate or acetate fibers. In international trade, their classification depends heavily on material composition and physical form (finished board vs. semi-finished). They are widely used in optical lenses, industrial modeling, packaging, and protective layers due to their transparency, water resistance, and machinability.
โ ๏ธ Key Distinction:
- Finished Boards (Plates/Sheets): Cut to size, ready for use โ Generally fall under Chapter 39.20 or 39.21 (Plastics sheets/plates).
- Raw/Semi-Finished Forms: Rolls, uncut sheets, or primary forms โ Generally fall under Chapter 39.12 (Cellulose ethers/esters).
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Authorityๅฏน็ ง)
| HS Code | Product Description | Application Scenario | Material/Form Note |
|---|---|---|---|
3921.19.00.90 |
Cellulose Acetate Precision Board, Material: Cellulose Acetate, Form: Board | Finished optical plates, industrial precision boards | โ Finished Board |
3912.11.00.00 |
Cellulose Acetate Precision Board, Material: Cellulose Acetate, Form: Primary/Semi-finished | Raw material, unprocessed sheets | โ Semi-finished |
3921.90.50.50 |
Cellulose Acetate Precision Board, Material: Synthetic Fiber/Plastic Class, Form: Board | General plastic-based acetate boards | โ Finished Board (General Plastic) |
3912.12.00.00 |
Cellulose Acetate Precision Board, Material: Cellulose Acetate, Form: Primary/Semi-finished | Rolls, uncut cellulose acetate sheets | โ Semi-finished |
3920.73.00.00 |
Cellulose Acetate Precision Board, Material: Cellulose Acetate, Form: Plate/Sheet/Film | Thin films, general-purpose acetate sheets | โ Finished Board (General) |
๐ Key Reminder:
- If the product is fully processed, cut, and ready for end-use, it is more likely classified under 3920 or 3921 (Finished plastic sheets/plates).
- If it is raw material, rolls, or in primary form, it falls under 3912 (Cellulose ethers/esters).
- Misclassification Risk: Declaring a finished board as "raw material" (3912) may trigger customs audits for undervaluation or wrong classification.

๐ VI. Common Mistakes & Pit-Avoidance Guide (Blood-and-Tears Lessons)
โ Mistake 1: Declaring finished boards as raw material rolls
๐ Consequence: Customs may reject for misclassification, delay release, or issue penalties.
โ Mistake 2: Declaring rolls as finished boards
๐ Consequence: Base rate difference (5.6% vs. 6.5%) may trigger duty discrepancy audits.
โ Mistake 3: Vague description: "Acetate Board" without specifying form
๐ Consequence: Customs cannot determine HS Code โ Delayed clearance or reclassification.
โ Mistake 4: Ignoring water resistance treatment
๐ Consequence: If coating changes material composition, may require different HS Code.
โ Correct Practice:
"Cellulose Acetate Precision Board, Water-Resistant, 2mm Thick, Cut to Size, Model XYZ, Finished Product for Optical Applications"
๐ฏ VII. Conclusion: Professional Declaration, Save Time & Cost!
๐ฏ Remember the Mantra:
๐น "Form Defines Code, Material Defines Rate; Finished vs. Semi-Finished, 35% Surcharge is Real!"
๐น "HS Code Determines Destiny, Tariff Differs by Point, One Step Wrong, Thousands in Taxes Lost!"
๐ Pro Tip:
If your cellulose acetate boards are originating from Vietnam, Mexico, Thailand, or Malaysia, you may apply for IEEPA Exemption, reducing tariffs to 0%~6.5%.

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
