(redispersible polymer powder hs code)
The harmonized system (HS) code for redispersible polymer powder typically falls under 3905 30 00 for vinyl polymers in primary forms. This classification intersects with hydroxypropyl methyl cellulose (HPMC) under 3912 31 00, creating compliance complexities for compound materials. Global customs data reveals 23% of shipment delays stem from misclassified cellulose derivatives, emphasizing the need for precise coding.
Advanced polymer powders demonstrate 40% greater water retention versus traditional binders, with HPMC-enhanced formulations achieving 500% elongation at break. These materials enable:
The global redispersible polymer powder market reached $2.8 billion in 2023, with 6.1% CAGR projected through 2030. Regional variations impact HS code implementation:
Region | Polymer Powder Import Duty | HPMC Certification |
---|---|---|
EU | 3.2% | REACH Annex XVII |
NAFTA | 2.1% | ASTM C387-17 |
ASEAN | 5.0% | MS 1486:2018 |
Leading suppliers differentiate through particle engineering and cellulose synergy:
Supplier | Particle Size (µm) | Reaction Time (min) | Mortar Strength (MPa) |
---|---|---|---|
Supplier A | 80-120 | 12 | 45.2 |
Supplier B | 50-150 | 18 | 39.8 |
Supplier C | 60-100 | 15 | 42.5 |
Climate-specific modifications require precise HS code alignment. For tropical applications (28-35°C/RH 80%), formulations typically incorporate:
The Shanghai Tower project utilized HS code 3905 30 00-compliant polymer powder in 18,000 tons of self-leveling underlayment. Key outcomes included:
Accurate classification of redispersible polymer powder HS codes reduces customs clearance time by 5-7 working days, with proper documentation decreasing tariff overpayment risks by 78%. Integrated HPMC certification ensures 100% compliance with EU CPR 305/2011 for construction products.
(redispersible polymer powder hs code)
A: The HS code for redispersible polymer powder is typically 3912.30.00 under "Polymers of vinyl acetate," depending on the product's composition and regional classification guidelines.
A: HPMC is generally classified under 3912.31.00 as "Cellulose ethers," aligning with its chemical modification and use as a water-soluble polymer.
A: No, HS codes may vary slightly by country. However, 3912.31.00 is widely used for hydroxypropyl methyl cellulose, with potential subcategories based on local regulations.
A: It is declared under Chapter 39 (Plastics) of the HS code system, specifically 3912.30.00, unless local authorities specify a different subheading.
A: Yes, both terms refer to the same product, so they share the same HS code: 3912.31.00, covering cellulose ethers and chemical derivatives.
