🧪 Vinyl Chloride Acrylate Copolymer (VCA)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: What Exactly is VCA?
Vinyl Chloride Acrylate Copolymer (VCA) is a specialized polymer resin produced by copolymerizing vinyl chloride with a small amount of an acrylic monomer (such as vinyl acetate, ethyl acrylate, or butyl acrylate). It is not a standard commodity plastic like PVC but a modified copolymer used primarily as a modifier, impact enhancer, or adhesive component.
In international trade, VCA is classified based on its chemical structure and primary use. It generally falls under Chapter 39 (Plastics and Articles Thereof). The critical distinction lies in whether it is a homopolymer (single monomer) or a copolymer (two or more monomers), and whether it is in primary forms (powders, granules, liquids).
⚠️ Key Classification Distinction:
- If the material is a copolymer of vinyl chloride and other unsaturated monomers (like acrylates) → HS 3904.60
- If the material is simply PVC plasticizers or additives without being a polymerized copolymer → HS 3907.90 or Chapter 38
- If it is a dispersion (latex/emulsion form) → HS 3901.20 or 3904.60 depending on specific polymer type
- If it is a finished article (e.g., pre-mixed paint or adhesive) → HS 3208 or 3506 (NOT Chapter 39)💡 Critical Note: VCA is often used as an impact modifier for PVC or in adhesives, coatings, and sealants. Importers must clearly declare the chemical composition to avoid misclassification as "PVC Resin" (3904.21/3904.30) or "Other Polymers" (3906.90).
📦 II. HS Code Classification Details (2026 Latest Tariff Reference)
| HS Code | Product Description | Applicable Scenario | Form | Key Characteristics |
|---|---|---|---|---|
| 3904.60.00.00 | Other vinyl-chloride copolymers | Primary form (powder, granules, liquid polymer) | Raw Material | Copolymer of VC + acrylate; used as modifier |
| 3901.20.00.00 | Polyvinyl alcohol (PVA) in primary forms | Rarely VCA, but confusion risk | Raw Material | Only if mislabeled as PVA |
| 3907.90.00.00 | Other polyacetals, other polyethers, and other epoxides | Incorrect for VCA | N/A | Do not use unless chemically different |
| 3906.90.00.00 | Other acrylic polymers in primary forms | Only if acrylate >50% by weight | Raw Material | If VC is minor component |
| 3208.90.90.00 | Paints & varnishes based on synthetic polymers | Finished Product | Liquid | If VCA is already mixed into paint/coating |
| 3506.91.00.00 | Ready rubber, ready adhesives | Finished Product | Paste/Gel | If VCA is part of a ready-to-use adhesive |
🔍 Focus Alert:
- Primary Form (Raw Material): Most VCA imported as raw chemical resin falls under 3904.60.00.00 ("Other vinyl-chloride copolymers").
- Finished Form (Coatings/Adhesives): If VCA is already dispersed in a solvent or resin system to make paint or glue, it moves to Chapter 32 or 35. Do not classify finished products under Chapter 39!

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Required Documentation Checklist
| Document | Mandatory? | Explanation |
|---|---|---|
| ✅ Certificate of Analysis (COA) | ✔️ | Must confirm % of vinyl chloride, acrylic monomer, and polymerization method. |
| ✅ SDS (Safety Data Sheet) | ✔️ | Critical for chemical safety; must match HS classification. |
| ✅ Technical Specification Sheet | ✔️ | Shows molecular weight, solubility, and intended use (modifier vs. resin). |
| ✅ Commercial Invoice | ✔️ | Clearly state "Vinyl Chloride Acrylate Copolymer, HS 3904.60". Avoid vague terms like "Plastic Powder". |
| ✅ Bill of Lading | ✔️ | Ensure weight and volume match invoice. |
| ✅ ECCN/Control Number | ✔️ | Check if VCA is subject to dual-use export controls (rare, but possible if high-purity). |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Raw Copolymer = 3904.60; Finished Paint = 3208.90; Don't Mix Them!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Raw VCA powder/granules | 3904.60.00.00 | Mistakenly declared as PVC Resin (3904.21) |
| VCA-based adhesive paste | 3506.91.00.00 or 3904.60 if pure | Declared as "Glue" without chemical breakdown |
| VCA mixed in liquid paint | 3208.90.90.00 | Declared as raw polymer → Severe Misclassification |
| VCA plasticizer (not polymerized) | 3907.90 or Chapter 38 | Declared as copolymer → Legal Risk |
⚠️ Warning:
- Do not declare VCA as "PVC Resin" (3904.21/3904.30) if it contains significant acrylate content.
- Do not declare finished products (paints/adhesives) under Chapter 39. Chapter 39 is strictly for primary forms (powders, liquids, semi-finished resins).
✅ 3. Special Handling Cases
| Case | Handling Advice |
|---|---|
| OEM Custom VCA | Provide customer formula + technical data sheet. Prove it’s a copolymer, not a mixture. |
| VCA in Dispersion (Latex) | If water-based emulsion, may fall under 3901.20 or 3904.60. Check if it’s a "dispersion" vs. "solution". |
| VCA as Additive (<5%) | If VCA is only a minor component in a larger formulation, the whole product may be classified differently. |
| Chinese Origin | Apply for Exclusion if available (check USTR list for HS 3904.60.00.00). Many VCA products have had exclusions removed. |

📌 VI. Common Errors & Pitfalls (Blood Lessons)
❌ Error 1: Declaring VCA as "PVC Resin" (3904.21)
👉 Consequence: If audited, customs may reassess under 3904.60, leading to back taxes + penalties. Also, different environmental regulations apply.
❌ Error 2: Declaring finished paints/adhesives under Chapter 39
👉 Consequence: Misdeclaration. Goods may be seized, returned, or fined. HS 3904.60 is for raw polymers, not finished formulations.
❌ Error 3: Ignoring IEEPA 10% Surcharge
👉 Consequence: Underpayment of duty. US Customs will assess additional 10% + interest on all past shipments from Nov 2025.
❌ Error 4: Using vague names like "Plastic Powder" on Invoice
👉 Consequence: Customs will request clarification, causing delayed clearance and potential detention fees.
✅ Correct Practice:
"Vinyl Chloride-Acrylic Copolymer Resin, Powder Form, HS 3904.60.00.00, TSCA Compliant, Not for Direct Food Contact"
🎯 VII. Conclusion: Professional Declaration, Cost Efficiency & Compliance
🎯 Remember the Mnemonic:
🔹 "Raw Copolymer = 3904.60; Finished Product = 32/35; Raw = 40.3% Tax; Finished = 41.5% Tax; Don't Mix!"
🔹 "HS Code Determines Tax; VCA is Not PVC; Chemical CoA is Key!"
📌 Tips:
- If your VCA is originating from Vietnam, Thailand, or Malaysia, you may qualify for lower or zero tariffs under USMCA or ASEAN agreements. Check Rules of Origin carefully.
- Apply for Advance Ruling (CBP Ruling) if you have a new formulation. It provides legal certainty.
- Keep Certificate of Analysis (COA) and SDS on file for every shipment. Customs may request them during audit.

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
