Most import problems are not caused by the machine. They are caused by something decided months earlier and not written down: the wrong voltage, a certificate nobody requested, a packing crate that fails inspection at the port, or a spare-parts list that exists only in somebody's head.
This page covers the six things worth settling before you place an order. It does not give you duty rates — those vary by country and by year, and a number copied from a blog is worse than no number. Instead it tells you what to ask, and where the authoritative answer lives.
1. Classify the machine properly (ask your customs broker, not the supplier)
Your machine will be classified under a Harmonized System (HS) code, and that code determines your duty rate and any import licensing.
Paper cup and paper bowl forming machines are commonly classified in the HS 8441 family — machinery for making up paper pulp, paper or paperboard. Which specific subheading applies depends on your country's tariff schedule and on how your machine is described. This is a question for a licensed customs broker in your country, not for your supplier. Get it in writing before you order, because the classification affects your landed cost and sometimes your import eligibility.
If you are in the US, the authoritative source is the USITC Harmonized Tariff Schedule; the EU has its own TARIC database; most other countries publish a national tariff schedule through their customs authority. All are free to search.
What we provide for this: a full commercial invoice, packing list, bill of lading and a machine specification sheet in English, so your broker has what they need to classify correctly.
2. Voltage, frequency and plug standard
This is the most common and most expensive avoidable mistake. A machine built for 380 V three-phase 50 Hz will not run correctly on 220 V single-phase 60 Hz — and rewiring a machine after it lands costs far more than specifying it at the factory.
Tell us at quotation stage:
- Voltage and phase (for example 380 V / 3-phase, or 220 V / 1-phase)
- Frequency (50 Hz or 60 Hz)
- Plug and panel standard your electrician expects
- CE is a self-declaration supported by a technical file. It is not a certificate issued by a government. What matters is whether the manufacturer holds a genuine technical file and a signed Declaration of Conformity naming your machine.
- The importer also carries obligations. Under EU rules, the entity placing machinery on the market — which may be you — must be able to show the declaration, the technical documentation and the marking. Buy the paperwork, not just the sticker.
- The US treats food-contact substances through the FDA framework; your board and coating supplier should be able to provide the relevant documentation.
- The EU regulates food-contact materials through framework rules, with specific provisions for plastics and for paper and board.
- Many other markets have their own registration or declaration requirements.
For reference, our standard builds are 3-phase 380 V (50 Hz) for most forming machines, and 220 V for the packing machine. These are defaults, not limits — but they must be settled before production starts, not after.
3. CE marking — what it actually means, and who is responsible
CE marking is a declaration by the manufacturer that the machine meets the applicable EU health, safety and environmental requirements. It is legally required to place most machinery on the EU market.
Two things buyers frequently misunderstand:
Ask for: a Declaration of Conformity naming the model and the standards applied, and the CE marking on the machine's nameplate. If a supplier cannot produce a declaration for the exact model, the sticker means nothing.
4. Food-contact and market-specific rules
The machine makes a food-contact product, so in many markets your cups — not just the machine — fall under food-contact material rules. Which rules apply depends on where you sell the cups:
Because rules change, check the current requirement with your own regulator or a compliance consultant before you commit to a board and coating combination. The machine you buy has to be able to seal the material you are legally allowed to sell. If you intend to run PLA-coated board, say so before the machine is built — it needs a different sealing configuration.
5. Wooden packing cases and ISPM 15
Machines ship in wooden crates, and wood packaging moving between countries is subject to phytosanitary rules — the international standard is ISPM 15. Compliant solid-wood packaging must be heat-treated or fumigated and stamped with the official IPPC mark.
If the crate does not carry the mark, your shipment can be held at the port, treated at your expense, or returned. This is a completely avoidable delay, and it is worth confirming in writing that your supplier uses IPPC-stamped crates or compliant processed wood such as plywood.
Also ask: how the machine is braced inside the crate, whether the electrical cabinet is protected from moisture, and whether fragile parts ship in separate boxes. A machine that arrives with a bent frame costs more than the freight saved on a lighter crate.
6. The documents your broker will ask for
Get these as a scanned set before the machine ships, not after:
| Document | Why it matters |
|---|---|
| Commercial invoice | Duty calculation and customs valuation |
| Packing list | Physical inspection and crate count |
| Bill of lading | Title document and release of goods |
| Machine specification sheet (English) | HS classification support |
| Certificate of origin | Preferential duty treatment, where your country has an agreement |
| Declaration of Conformity (if applicable) | CE / market access evidence |
| Fumigation / IPPC evidence | Port clearance of wood packaging |
| Spare parts list with part numbers | Future sourcing, and often required for the invoice to be complete |
The five things that go wrong — and how to avoid them
① The machine arrives and will not run.
Cause, almost always: voltage or frequency mismatch. Fix: settle it in writing at quotation.
② The crate is held at the port.
Cause: wood packaging without an IPPC mark. Fix: confirm compliant crates in the contract.
③ The machine is held for missing paperwork.
Cause: a Declaration of Conformity that does not name the actual model. Fix: require it before shipment.
④ Nobody knows which parts to reorder.
Cause: no part numbers in the documentation. Fix: require a spare-parts list with numbers as a delivery document.
⑤ The board you planned to buy cannot legally be sold in your market.
Cause: coating and food-contact rules checked after the machine was ordered. Fix: check the material rules first — the machine follows the material, not the other way round.
What we can put in the quotation
Tell us your import country and port, and we will include: the voltage build, the certificate set you need, the packing specification, the spare-parts list with part numbers, and a realistic lead time to your door.
