π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Understand "MEPP Adhesive"?
Methyl Ethyl Propyl Phosphate (MEPP) is a complex chemical substance. While commercially sold as an "adhesive," it is chemically a phosphate ester used primarily as a: 1. Plasticizer: For plastics and rubber. 2. Solvent: For lacquers, resins, and adhesives. 3. Flame Retardant: For textiles and plastics. 4. Adhesive Component: Often used as an auxiliary or primary binder in specific industrial bonding applications.
In international trade, the classification depends on its primary function and composition: * As a Pure Chemical Compound: If it is MEPP in pure form, it falls under Chapter 29 (Organic Chemicals). * As a Formulated Adhesive: If it is mixed with other binding agents, fillers, or solvents specifically for bonding, it falls under Chapter 35 (Albuminoidal Substances; Glues; Enzymes) or Chapter 39 (Plastics), depending on the primary binding agent.
β οΈ Key Distinction:
- If it is pure MEPP (a single chemical entity) β 2920.90.00.00
- If it is a formulated glue/adhesive containing MEPP as an ingredient β 3506.91.00.00 (or similar, depending on the main binder)
- If it is a solvent mixture where MEPP is the main component and used for cleaning/prepping β 3824.99.94.00
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Is it a Pure Chemical? |
|---|---|---|---|
2920.90.00.00 |
Esters of inorganic acids (phosphates) and their salts, including lactophosphates | Pure MEPP, used as a plasticizer, solvent, or additive | β Yes |
3506.91.00.00 |
Prepared glues and other prepared adhesives, whether or not in the form of sheets or rolls, other than products of heading 35.01 or 35.02 | Formulated MEPP-based adhesives, mixed with resins/fillers | β No (Formulated) |
3824.99.94.00 |
Prepared binders for foundry molds or cores; Chemical products and preparations of the chemical or allied industries... | MEPP used primarily as a solvent or cleaning agent in industrial formulations | β No (Mixture/Preparation) |
3906.90.00.00 |
Acrylic polymers in primary forms | If MEPP is added to acrylics to modify them, the final product might fall here if the adhesive property is secondary | β No |
π Critical Reminder:
- Pure MEPP is classified under 2920.90.00.00.
- If the product is labeled "Adhesive" but is pure MEPP, customs may still classify it as a chemical (2920) if the primary use is as a plasticizer/solvent.
- If it is a mixed formulation (e.g., MEPP + Epoxy Resin), it is classified as a glue (3506).
- Misclassification Risk: Declaring a formulated adhesive as a pure chemical (2920) can lead to underpayment of duties and penalties.

β 2. Declaration Tips (Key Mnemonic)
π₯ "Pure Chemical = 2920, Formulated Glue = 3506, Solvent = 3824. Be Specific!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Pure MEPP | 2920.90.00.00 "Methyl Ethyl Propyl Phosphate, Pure" |
Misdeclaring as "Adhesive" (3506) β Penalty |
| MEPP mixed with Epoxy | 3506.91.00.00 "Prepared Adhesive, MEPP-based" |
Misdeclaring as "Pure Chemical" β Undervaluation |
| MEPP as Industrial Solvent | 3824.99.94.00 "Chemical Preparation, Solvent" |
Misdeclaring as "Adhesive" β Classification Error |
β 3. Special Handling Cases
| Case | Handling Advice |
|---|---|
| OEM/Custom Formulation | Provide the exact formula. If the main binder is epoxy, use 3506. |
| Hazardous Material | MEPP is flammable and may be toxic. Ensure UN Number and Hazmat Declaration are complete. |
| Food Grade vs. Industrial | If for food packaging, FDA compliance is critical. Industrial grade is cheaper but restricted. |
| Sample Shipment | Even samples are subject to full tariffs. Do not use de minimis exemptions. |

π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Declaring a formulated adhesive as a pure chemical
π Consequence: Customs may reject the declaration, leading to penalties and delays.
π Correct Action: Provide a full formula and classify as 3506.
β Error 2: Ignoring Hazmat Classification
π Consequence: MEPP is flammable. Failure to declare can lead to shipment seizure or fines.
π Correct Action: Always include SDS and UN Number.
β Error 3: Assuming De Minimis Exemption Applies
π Consequence: No exemption for chemical products from China.
π Correct Action: Pay all taxes upfront, even for samples.
β Error 4: Using "Glue" as a Generic Term
π Consequence: Ambiguity leads to audits and reclassification.
π Correct Action: Use precise chemical names or specific adhesive types.
β Correct Declaration Example:
"Methyl Ethyl Propyl Phosphate, Chemical Grade, Pure, CAS 103-58-0, HS 2920.90.00.00, Flammable Liquid, UN 1993"

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
