Importing custom silicone molds from China is straightforward when documents, sample approval, and freight terms are locked before deposit - not discovered at customs. RUUIPON ships from Shenzhen worldwide for brands ordering MOQ 50 production trays with prototypes in 3-7 days. This guide covers what US, EU, UK, and AU buyers actually need on the paperwork side.
Quick answer: Approve a physical prototype before MOQ 50 production; request commercial invoice with accurate HS description, material statement (platinum silicone), cavity count, and food-grade test reports if applicable. Use DAP or DDP with a forwarder you trust; inspect flash, cavity dimensions, and lip QC on arrival before signing off the full PO.
Import Flow in Four Steps
- Quote + prototype - CAD, application, market; sample in 3-7 days.
- Sample approval - cast test, flash QC, dimension check.
- Production MOQ 50 - ~2-4 weeks after sign-off.
- Ship + inbound QC - verify count, tray IDs, docs match PO.
| Document | Purpose |
|---|---|
| Commercial invoice | Customs value; product description |
| Packing list | Carton count, weights, dimensions |
| Material statement | Platinum-cure silicone; food grade if ordered |
| Test reports (if food) | FDA-compliant / LFGB supplier docs as available |
| CAD revision letter | Links shipment to approved geometry |
| Prototype approval email | Audit trail for disputes |
Documents & Customs Basics
HS classification varies by country - your broker classifies; you supply an accurate plain-language description: "custom platinum silicone mold trays, 12-cavity, food contact" not "plastic molds."
- Declared value - matches invoice; lowballing risks holds and penalties.
- Country of origin - China (CN) for RUUIPON production.
- No steel tooling confusion - silicone trays are elastomer tooling, different compliance story than metal press molds.
- Brand name on invoice - your OEM name if private label. Private label OEM.

Incoterms & Freight Choices
| Term | Buyer handles | Best for |
|---|---|---|
| EXW Shenzhen | All freight + import clearance | Buyers with own forwarder |
| FOB Shenzhen | Ocean/air after port handoff | Regular importers |
| DAP (door) | Import duty/tax at destination | Most DTC brands |
| DDP | Little beyond receiving | First-time importers (higher quote) |
| Express (DHL/FedEx) | MOQ 50 small cartons | Fast prototype or urgent reorder |
MOQ 50 trays often ship by air express in 1-2 cartons - confirm dimensional weight before assuming "small = cheap freight."
Food-Contact Compliance for Import Markets
US retail and Amazon often ask for FDA-compliant silicone documentation. EU/Germany may require LFGB migration test reports from the silicone supplier batch.
- Request docs before production - not after customs clearance.
- Match batch/lot on report to material batch when possible.
- We supply supplier documentation available - we do not claim certs the batch cannot support.
Compare: FDA vs LFGB. Cleaning after import: food-safe cleaning. Confectionery: food solutions.
Sample Approval Gate (Do Not Skip)
The costliest import mistake is approving production remotely without a physical prototype cast with your material.
- Receive prototype (3-7 days after CAD OK).
- Run 10+ casts; check weight, logo, demold, flash. Flash QC.
- Measure critical dimensions vs drawing (account ~0.1% silicone shrink).
- Email written approval referencing CAD revision.
- Only then authorize MOQ 50 production.

Inbound QC When Cartons Arrive
| Check | Action if fail |
|---|---|
| Carton count vs packing list | Photo + notify supplier same day |
| Tray warpage from heat transit | Flat rest 24h; document if permanent |
| Cavity count and tray ID | Match PO line items |
| Flash / lip on 3 random trays | Reject lot if systemic trim fail |
| Food docs in envelope | File before first retail lot |

Reorder, Scale & Working with RUUIPON
Repeat orders of the same CAD revision skip prototype - typical production 2-4 weeks. Geometry changes restart 3-7 day prototype. Volume reorders of 100-200 often get unit pricing without new master charge.
