The HS Code Commonly Used for Wallpaper Glue Powder
Wallpaper glue powder (modified starch / CMS based) is usually classified either under adhesive headings (Chapter 35) or modified-starch headings (Chapter 11). The exact HS code depends on raw-material composition, finished form, and the destination customs authority's interpretation.
Key point: Always rely on the destination country's customs ruling and your local classification opinion. The factory can support by providing a composition statement, usage description and TDS to assist declaration.
Which Documents an Importer Should Prepare
A complete import document set usually includes the items below. COA, TDS and MSDS are issued by the factory per batch; the packing list and shipping marks must match the actual outer cartons.
| Document | Issued by | Purpose |
|---|---|---|
| Proforma Invoice (PI) | Factory | Order confirmation & payment basis |
| Commercial Invoice | Factory | Customs valuation |
| Packing List | Factory | Quantity & weight verification |
| Bill of Lading (B/L) | Forwarder | Title & transport proof |
| COA (batch test) | Factory | Quality data per batch |
| TDS | Factory | Technical parameters & mixing ratio |
| MSDS | Factory | Safety, storage & emergency handling |
| Shipping Marks | Factory | Carton identification & scanning |
The Different Roles of COA, TDS and MSDS
These three documents serve different purposes. Customs, distributors and end buyers all rely on them at different stages.
- COA reflects the batch test data: viscosity, moisture, appearance.
- TDS describes technical parameters, mixing ratio and typical use.
- MSDS provides safe storage, transport and emergency handling.
Tip: Agree on file format (PDF / paper), language (bilingual or single) and delivery timing (before or after container loading) before the first order.
Shipping Marks Must Match the Packing List
A large share of customs problems comes from a mismatch between outer-carton shipping marks and the packing list. Outer cartons should clearly show:
- Product name
- Net / gross weight
- Batch number
- Production date
- Country of origin
- Consignee information
Hangzhou Karn can label cartons in the buyer's specified mark format; the buyer provides the mark content and labeling requirements.
Shipping to the Buyer's Nominated China Forwarder Warehouse
Hangzhou Karn is a China-based factory and exporter and can deliver to a China forwarder warehouse nominated by the buyer. The buyer needs to provide:
- Warehouse name and address
- Receiving contact and phone
- Customer code (warehouse-in number)
- Delivery time window
Important: We do not operate a local office or local warehouse overseas. Import customs clearance and local distribution are handled by the buyer.
Next Step
If you are preparing wallpaper glue powder import customs clearance, first confirm HS code classification with your destination customs broker, then request COA, TDS, MSDS and a packing-list sample from the factory to cross-check.
