🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Inkjet Filter Paper"?

Inkjet Filter Paper, also known as paint filters or strainers in industrial contexts, is a specialized cellulose-based product used primarily in the printing, automotive, and chemical industries. Its main function is to remove particulate impurities, agglomerates, and contaminants from inks, paints, coatings, and solvents before they enter the inkjet printing system or application equipment. Failure to filter these particles can result in clogged nozzles, print defects, or equipment damage.

In international trade, filter paper is categorized based on its specific end-use and form. For "Inkjet Filter Paper," the key distinction lies in whether it is specifically designed as a filter/strainer or general-purpose filter paper.

⚠️ Key Distinction Point:
- If the paper is specifically manufactured as a filter or strainer (e.g., cup filters, bag filters, or sheet filters designated for straining liquids like ink/paint) → It falls under HS Code 4823.20.10.00 ("Paint filters and strainers").
- If the paper is general-purpose filter paper not specifically identified as a "paint filter" or "strainer" (e.g., laboratory filter paper, general industrial filtration media) → It falls under HS Code 4823.20.90.00 ("Other").

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

🔍 Critical Reminder:
- Both HS Codes carry the same total tariff rate of 25% for imports from China to the US.
- However, correct classification is crucial for customs compliance, audit risk, and potential future tariff changes.
- "Inkjet filter paper" is typically considered a paint/filter strainer if it is shaped or sized specifically for straining ink cartridges or systems → Prefer 4823.20.10.00.
- If it is generic filter paper sold in rolls or sheets for general use, use 4823.20.90.00.
