🌿 Sponge (Sponge套 / Sponge Cover) – Comprehensive HS Code & Tariff Guide (2026 Update)

🌐 HS Code Classification & Customs Clearance Strategy | 2026 Latest Tariff Breakdown | Expert-Level Compliance Guide

📌 One: Product Definition & Classification – What Exactly Is a “Sponge” in Global Trade?

A sponge (especially in the form of a sponge套 or sponge cover) is a porous, soft, flexible material used for cleaning, cushioning, sealing, or protective purposes. In international trade, its classification depends heavily on material composition and functional form.

⚠️ Critical Insight:
- If the sponge is made from rubber (natural or synthetic) → likely rubber-based product
- If the sponge is made from polyurethane or plastic foam → classified as plastic
- If used as a clothing accessory (e.g., a sleeve, cover, or sock-like item) → may fall under textile or apparel parts

🔍 Key Question:
Is it a standalone foam piece? Or a wearable or functional cover?
