π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Understand "Chloride Anti-Rust Adhesive"?
"Chloride Anti-Rust Adhesive" is a specialized industrial adhesive designed to resist corrosion, particularly in environments containing chlorides (such as marine or de-icing salt environments). It is typically used for bonding metals, plastics, or composites where rust protection is critical.
In international trade, prepared adhesives are classified based on their chemical composition and packaging:
- Polymer-Based Adhesives: If the adhesive is based on polymers of headings 3901 to 3913 (e.g., acrylics, epoxies, polyurethanes) or rubber.
- Retail Packaging Constraint: A critical distinction is made for products put up for retail sale. If the net weight exceeds 1 kg, it falls under a different category. The data provided specifically addresses products not exceeding 1 kg net weight.
β οΈ Key Distinction Point: - Polymer/Rubber Base: If the adhesive is chemically based on polymers (headings 3901-3913) or rubber, it falls under heading 3506.91. - Other Base: If it is not based on these polymers/rubbers (e.g., mineral-based, animal-based, or unspecified prepared adhesives), it falls under heading 3506.99. - Retail Weight Limit: The classification below applies to packages of β€ 1 kg net weight. Larger packages are excluded from this specific sub-heading analysis.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)
| HS Code | Product Description | Applicable Scenario | Chemical Basis |
|---|---|---|---|
3506.91.50.00 |
Prepared adhesives based on polymers (3901-3913) or rubber; Other | Specialized anti-rust glues where the binder is a polymer/rubber; Retail β€1kg | β Polymer/Rubber Base |
3506.99.00.00 |
Prepared adhesives; Other | Glues not based on polymers (3901-3913) or rubber; Retail β€1kg | β Non-Polymer/Non-Rubber Base |
π Important Reminder: - If your "Chloride Anti-Rust Adhesive" uses a polymer binder (like epoxy, acrylic, or rubber-based adhesives), it must be classified under
3506.91.50.00. - If it is a generic prepared adhesive not meeting the polymer/rubber definition (or classified as "other" under customs interpretation), it falls under3506.99.00.00. - Packaging is Critical: If the net weight is >1 kg, these specific HS codes do not apply. You must consult the broader "Other adhesives" categories.

| De Minimis Eligibility | β No (Subject to surcharge) |
| Legal Basis Path | USITC:3506.99.00.00 β Footnote: 25% Surcharge |
π Explanation: - "Other" prepared adhesives (not polymer/rubber-based or not fitting the specific polymer description) are subject to a 2.1% base tariff plus a 25% surcharge. - The 25% surcharge is typically associated with Section 301 tariffs on Chinese goods. - Total duty of 27.1% is significantly higher than the polymer-based alternative. - This classification is a cost trap if the product can be technically classified under the polymer category.
π οΈ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
β 1. Documentation Checklist (Mandatory)
| Document | Must Provide | Explanation |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must explicitly state the chemical base (e.g., "Epoxy-based," "Acrylic polymer," "Rubber-based"). Avoid vague terms like "Chemical Adhesive." |
| β Technical Data Sheet (TDS) | βοΈ | Show SDS/MSDS to prove the polymer/rubber content. Highlight sections describing the binder/resin. |
| β Commercial Invoice | βοΈ | Clearly state: "Prepared Adhesive, Polymer-Based, Retail Package β€1kg, Anti-Rust Chloride Resistant." |
| β Packing List | βοΈ | Confirm Net Weight β€ 1 kg per retail unit. If bulk, clarify if it's for retail resale. |
| β Photo of Label/Packaging | βοΈ | Show the front label indicating weight and product type. |
β 2. Classification Strategy (Key Mantra)
π₯ "Check the Binder, Check the Weight, Choose the Code, Save the Duty!"
| Scenario | Correct HS Code | Duty Rate | Risk |
|---|---|---|---|
| Polymer/Rubber Base + β€1kg | 3506.91.50.00 |
0.0% | β Low |
| Non-Polymer Base + β€1kg | 3506.99.00.00 |
27.1% | β High Cost |
| Any Base + >1kg Net Weight | β Not Covered | N/A | β οΈ Re-classification Needed |
| Bulk Industrial Glue (>1kg) | β Not Covered | N/A | β οΈ Different Tariff Line |
π Critical Tip:
- Do NOT simply label it "Anti-Rust Glue." Customs looks at the chemical composition.
- If the adhesive is epoxy, polyurethane, acrylic, or rubber-based, argue for3506.91.50.00.
- If you classify it as "Other" (3506.99.00.00) without justification, you may pay 27.1% unnecessarily.
β 3. Special Circumstances
| Situation | Handling Advice |
|---|---|
| Hybrid Adhesive | If it contains polymers AND other bases, consult SDS. If polymer is the primary binder, use 3506.91.50.00. |
| Retail Definition | If sold in bulk drums (>1kg) for industrial use, these HS codes do not apply. Use broader "Other adhesives" codes. |
| Chloride Resistance Claim | This is a performance feature, not a chemical definition. It does not change the HS code unless it changes the base chemistry. |
| De Minimis (Section 321) | If shipping individually to consumers (<$800), 3506.91.50.00 is duty-free. 3506.99.00.00 may still be subject to duties depending on current de minimis rules (check latest CBP updates). |

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