๐ญ Dissolved Sulfite Pulp for Artificial Fiber (Rayon/Viscose Production)
๐ HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
๐ I. Product Definition and Classification: What is "Dissolved Pulp"?
Dissolved Sulfite Pulp is a highly purified form of wood pulp specifically produced for the manufacturing of artificial fibers (such as viscose rayon) and cellulose derivatives. Unlike standard pulp used for paper, this material undergoes rigorous chemical treatment to remove lignin, hemicellulose, and other impurities, resulting in a high alpha-cellulose content (>90%) and low viscosity.
In international trade, it is critical to distinguish between: 1. Standard Wood Pulp: Used for paper/cardboard (HS 4703). 2. Dissolved Pulp: Used for chemical conversion into fibers or films (HS 4704).
โ ๏ธ Key Distinction Point:
- If the product is intended specifically for dissolving into viscose/rayon, it must be classified under 4704 (Chemical Wood Pulp, Sulfite).
- Do not confuse it with pulp for paper (4703) or chemical fibers themselves (5402/5403). The process (dissolving) and destination (fiber production) define the classification.
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Key Characteristics |
|---|---|---|---|
4704.11.00.00 |
Chemical Wood Pulp, Sulfite, of Coniferous Origin, Unbleached | Sulfite pulp derived from pine, spruce, fir, etc., before bleaching | High lignin removal via sulfite process; raw state |
4704.20.00.00 |
Chemical Wood Pulp, Sulfite, of Non-Coniferous Origin, Unbleached | Sulfite pulp derived from eucalyptus, birch, hardwood, etc., before bleaching | Different fiber structure; used for specific fiber grades |
4704.11.10.00 |
Chemical Wood Pulp, Sulfite, Coniferous, Unbleached โ Dissolved Grade | Specifically refined sulfite pulp for viscose/rayon from conifers | High purity, high alpha-cellulose, low viscosity precursor |
4704.20.10.00 |
Chemical Wood Pulp, Sulfite, Non-Coniferous, Unbleached โ Dissolved Grade | Specifically refined sulfite pulp for viscose/rayon from hardwoods | High purity, high alpha-cellulose, low viscosity precursor |
4704.30.00.00 |
Chemical Wood Pulp, Sulfite, Bleached | Bleached sulfite pulp (less common for direct dissolved fiber) | Additional bleaching step; may have different tax treatment |
๐ Critical Reminder:
- Unbleached vs. Bleached: Most dissolved pulps for rayon are traded in unbleached form to preserve fiber strength during the chemical dissolution process. Bleached pulp (4704.30) may incur different tariffs. - Coniferous vs. Non-Coniferous: Customs authorities strictly require proof of wood origin (e.g., Eucalyptus vs. Pine). Misdeclaration can lead to severe penalties. - "Dissolved" is a Grade, Not a HS Code: The term "dissolved" describes the quality/purpose, but the HS Code is determined by the process (sulfite) and origin (coniferous/non-coniferous).

๐ VI. Common Errors & Pitfalls (Lessons Learned)
โ Error 1: Declaring as "Wood Pulp for Paper" (4703)
๐ Consequence: If customs discovers itโs sulfite/dissolved grade, they may reclassify to 4704 and assess back-duties + penalties.
โ Error 2: Omitting Wood Species in Declaration
๐ Consequence: Customs cannot determine if itโs coniferous (4704.11) or non-coniferous (4704.20), leading to hold at port.
โ Error 3: Missing Phytosanitary Certificate
๐ Consequence: Rejected entry or forced fumigation at importerโs expense.
โ Error 4: Using "Rayon" in the Product Name
๐ Consequence: Customs may suspect textile smuggling or misclassification. Use "Chemical Wood Pulp" as the primary name.
โ Correct Declaration Example:
"Chemical Wood Pulp, Sulfite, Unbleached, Coniferous Origin, Dissolved Grade, Alpha-Cellulose 92%, Model: DP-92, Packed in Bales, No Phytosanitary Issues"
๐ฏ VII. Conclusion: Precision in Raw Material Trade
๐ฏ Remember the Mantra:
๐น "Sulfite is Key, Origin Defines Code, Phytosanitary is Mandatory, Tariff is 17.5% in US."
๐น "HS Code 4704 saves time, 4703 causes fines, species matters!"

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
