🧪 PCTs Chlorinated Adhesives & Chemical Binders
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level
⚠️ CRITICAL WARNING: REGULATORY CONSTRAINTS
The term "PCTs" (Polychlorinated Terphenyls) refers to a group of synthetic organic compounds that were historically used as dielectric fluids and heat transfer media. However, PCTs are strictly regulated and largely banned globally under the Stockholm Convention on Persistent Organic Pollutants (POPs).If your product genuinely contains PCTs, it falls under highly restricted chemical preparations (HS 3824.82) and faces severe import restrictions or outright bans in many jurisdictions.
If "PCTs" was used loosely to refer to general chlorinated hydrocarbon adhesives or binders, the correct classification likely shifts to HS 3824.99.50.00 or HS 3506.99.00.00. The analysis below strictly adheres to the provided data, distinguishing between the restricted PCT-containing category and general chlorinated adhesives.
📦 I. HS Code Classification Breakdown (Strictly Based on Provided Data)
The following HS Codes are derived directly from the input data. They cover two distinct scenarios: 1. Restricted PCT-containing products (HS 3824.82.10.00). 2. General chlorinated hydrocarbon binders/adhesives (HS 3824.99.50.00). 3. Retail-sourced adhesives (HS 3506.99.00.00).
| HS Code | Product Description | Key Classification Criteria | Tax Status |
|---|---|---|---|
3824.82.10.00 |
Prepared binders for foundry molds or cores; chemical products... Goods specified in subheading note 3 to this chapter: Containing polychlorinated biphenyls (PCBs), polychlorinated terphenyls (PCTs) or polybrominated biphenyls (PBBs): Chlorinated but not otherwise halogenated | Contains PCTs/PCBs/PBBs. Strictly regulated POPs. "Chlorinated but not otherwise halogenated." | 0.0% (Base & Additional) |
3824.99.50.00 |
Prepared binders for foundry molds or cores; chemical products... Other: Other: Other: Other: Mixtures of halogenated hydrocarbons: Chlorinated but not otherwise halogenated | Does NOT contain PCTs/PCBs. General chlorinated hydrocarbon mixtures. Used as binders or chemical preparations. | 0.0% (Base & Additional) |
3506.99.00.00 |
Prepared glues and other prepared adhesives... put up for retail sale... not exceeding a net weight of 1 kg: Other: Other | Retail packs ≤ 1kg. General adhesives (not specifically PVC/rubber-based). | 27.1% (Base 2.1% + Additional 25.0%) |
3506.91.50.00 |
Prepared glues... put up for retail sale... not exceeding a net weight of 1 kg: Other: Adhesives based on polymers of headings 3901 to 3913 or on rubber: Other | Retail packs ≤ 1kg. Adhesives based on polymers (e.g., EVA, Polyurethane) or rubber. | 0.0% (Base & Additional) |
🔍 Key Distinction:
- HS 3824.82.10.00 is for regulated substances (PCBs/PCTs).
- HS 3824.99.50.00 is for general chlorinated hydrocarbon mixtures (non-PCBs/PCTs).
- HS 3506 codes are for retail-sized consumer adhesives (≤1kg).
- DO NOT confuse PCT-containing binders (3824.82) with general chlorinated binders (3824.99).
💰 II. 2026 Tariff Rate Detailed Analysis (Import to USA)
✅ Applicable Country: United States (US)
✅ Origin: China (CN) [Assumed based on typical trade context, but verify actual origin]

| Total Tariff | 0.0% |
| Legal Note | Despite 0% tariff, this code is subject to strict environmental regulations (EPA, Stockholm Convention). Import may be prohibited or require special permits. |
| Risk Level | 🔴 HIGH. Legal compliance risk outweighs tariff cost. |
📌 Explanation:
- The tariff is 0%, but the product is a Persistent Organic Pollutant (POP).
- Customs may block entry if not properly declared as restricted material or if banned in the destination country.

🛠️ III. Customs Clearance Operational Advice
✅ 1. Documentation Checklist (Must-Haves)
| Document | Required? | Purpose |
|---|---|---|
| Safety Data Sheet (SDS) | ✔️ Mandatory | To prove no PCT/PCB content for 3824.99.50.00. |
| Certificate of Analysis (COA) | ✔️ Mandatory | Chemical composition breakdown. Critical for distinguishing 3824.82 from 3824.99. |
| Commercial Invoice | ✔️ Mandatory | Clearly state "Chlorinated Hydrocarbon Mixture" or "Prepared Adhesive". Avoid vague terms. |
| Import License/Permit | ✔️ If Applicable | Required for 3824.82.10.00 (regulated substances). |
| Retail Packaging Photos | ✔️ If ≤1kg | To justify 3506 codes. Show net weight clearly. |
✅ 2. Declaration Strategy (Key Tips)
🔥 "Prove it's Not PCT, Or You're Blocked!"
| Scenario | Correct Declaration | Wrong Declaration | Consequence |
|---|---|---|---|
| General Chlorinated Binder | "Chlorinated hydrocarbon mixture, free of PCBs/PCTs, for industrial use" | "PCT-containing adhesive" | Misclassification. Penalty for false declaration. |
| Retail Glue (≤1kg) | "Adhesive based on [Polymer Name], retail pack, 0.5kg net" | "Industrial glue" | Wrong HS Code. Potential 27.1% tax instead of 0%. |
| Retail Glue (Polymer/Rubber) | "Adhesive based on polymer of heading 3901, retail pack" | "General adhesive" | Avoids 27.1% tariff. Saves money. |
| PCT-Containing Product | "Prepared binder containing PCTs (Subject to POPs Regulations)" | "General chemical" | Illegal import. Seizure and fines. |
✅ 3. Special Circumstances
| Situation | Handling Advice |
|---|---|
| Ambiguous "Chlorinated" Product | If unsure if it contains PCTs, test it. If it does, use 3824.82.10.00 but check local import bans. If not, use 3824.99.50.00. |
| Mixed Packaging | If >1kg, do not use 3506. Use 3824 codes instead. |
| Polymers vs. General Adhesives | If adhesive is based on polymers (e.g., PVC, PE), it must be classified under 3506.91 or 3506.99 if retail, or 3901-3913 if primary forms. |
| Foundry Binders | If used for foundry molds, ensure description matches "Prepared binders for foundry molds or cores" to align with Chapter 38. |

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