A cleaning machine is built, tested and crated, and then the shipment stalls at the forwarder’s desk because three documents describe the same machine three different ways. Export paperwork is machine data: four published facts decide the classification, the freight, and every declaration that follows.
The four facts already sit on our product pages. The CQ-C9610 Inline PCBA Water Cleaning Machine prints 6,560 × 1,760 × 1,660 mm at approx. 2,600 kg on AC380V 50Hz 65A. The CQ-C756 Fixture & Pallet Cleaning Machine prints 1,800 × 1,550 × 1,500 mm at 27 kW. The CQ-C770 Automatic Squeegee Cleaning Machine prints 1,000 × 1,000 × 1,600 mm at a net 260 kg. One invoice line reads “cleaning machine” for all three, while length differs by 3.6 times and weight by ten times. (Source: CHUANGQI product specification pages, read 2026-10-29.)
Key takeaways
- Headings describe machines by what they do and how they are built.
- Three published machines differ 3.6× in length and 10× in weight.
- Six documents travel with a shipment, and each one anchors a different fact.
- Gross weight covers crate and pallet; the datasheet prints machine weight only.
- Send destination country and packing preference with the RFQ, not after the deposit.
Four machine facts decide the classification and the freight
This checklist comes from the specification pages we publish for 22 machines and from the document set that leaves the factory with each one. It is a preparation guide, not a tariff ruling: the classification itself stays with the importer and their broker, and the cleaning machine HS code they settle on follows the function of the equipment rather than the words a supplier prefers.
Function: what the machine does to the product decides more than its name. A washer that projects cleaning fluid at a PCBA, a cabinet that blasts dry ice, and a unit that lifts dust with ionised air solve three different problems, and the World Customs Organization nomenclature sorts machinery by function and design for exactly that reason. How a broker reads a given machine depends on the heading text, any section or chapter notes, and the technical description supplied with the entry.
Outline and weight: freight is priced on the space a crate occupies and the mass it carries, not on the machine’s footprint drawing. Across the three machines above, published net weight runs from 260 kg (CQ-C770) to approx. 2,600 kg (CQ-C9610), and the crate adds its own framing, pallet and bracing on top. Whether a shipment moves as a full container or shares one depends on packed volume, crate count, and the route the forwarder books.
Power configuration: the CQ-C9610 page prints AC380V 50Hz 65A and, in the same table, 3PH, 380 VAC, 5 wires. Destination power is a build question that gets settled at order stage, and the answer belongs on the technical description your broker attaches — a declaration that contradicts the machine plate invites a second look.
What travels with the machine: a water-based cleaning fluid is chemistry with its own description, and some formulations carry transport restrictions that a machine does not. Spare baskets, nozzles, filter cartridges and fixture sets are separate articles. Every one of them makes the packing list longer and the entry more specific.

What do the six export documents each have to match?
Each document is a witness to one fact. Clearance gets difficult when two witnesses disagree, and the disagreement is almost never about the machine — it is about which version of the data someone copied.
| Document | Issued by | Machine fact it must match | Where it breaks |
|---|---|---|---|
| Commercial invoice | Seller | Model designation and what the machine does | Invoice says “cleaning machine”, datasheet says inline PCBA washer |
| Packing list | Seller or packer | Packed dimensions and gross weight | Machine outline copied instead of crate outline |
| Bill of lading or air waybill | Carrier | Package count and gross weight | Count changes after crating, nobody updates the list |
| Certificate of origin | Issuing body | Country of manufacture | Requested after the vessel is booked |
| Export declaration | Seller’s broker | Classification, value and quantity | Filed before the final packing list exists |
| Insurance certificate | Seller or buyer, per agreement | Insured value and route | Issued before the delivery arrangement is fixed |

The pattern in the last column is the same every time: a document gets drafted from an early internal number and never re-read against the final one. A machine sells on a drawing that later changes with a guard rail or platform revision, and the packing list inherits the drawing instead of the crate.
Where shipments stall on a single mismatch
Four fields account for most of the friction we see on machine shipments, and all four are cheap to fix before the crate closes:
- Net weight versus gross weight. The datasheet prints machine weight. The packing list needs the weight the crane will lift, crate and pallet included.
- Machine outline versus crate outline. Access clearance, forklift pockets and bracing all sit outside the printed dimensions.
- Model designation across documents. One model name, spelled the same way on invoice, packing list and declaration.
- Accessories inside the same crate. Baskets, nozzles and spare filters are separate articles; list them, or the entry gains a line at the port.
| Mismatch | Who catches it first | What it delays |
|---|---|---|
| Gross weight vs net weight | Forwarder, at booking | Freight quote, then container loading |
| Crate outline vs machine outline | Trucking company, at pickup | Vehicle assignment and door clearance |
| Function description vs classification | Destination broker, on entry | Release of the container for examination |
| Accessories missing from the entry | Customs, at inspection | The whole consignment, not just the box |

What does this checklist not decide?
Three things stay outside a supplier’s scope, and saying so is more useful than pretending otherwise. The tariff rate that applies to your entry is set by the importing jurisdiction and calculated by your broker, so we publish no rate and no ruling. Whether your destination asks for additional product documentation is a question for your compliance contact, not for a machine builder. And a used or refurbished machine follows a different entry path from a new one — our specification pages describe new machines only.
This preparation guide is not suitable for mixed consignments that combine machinery with a charge of cleaning chemistry, or for project shipments where several machines and a fixture set are packed together. Those need a packing plan drawn by the forwarder before anything is crated.
The work itself takes one email. Send the destination country, the delivery arrangement you intend to agree, and any packing requirement your site imposes (door width, crane capacity, crate marking) with your enquiry, and our team will return the shipping data from the specification page, a draft packing list and a quote within 24 hours. The technical baseline for the machine that usually starts these enquiries is the CQ-C9610 Inline PCBA Water Cleaning Machine page. What to put in the enquiry before a quote exists is set out in the seven RFQ fields that decide your quote, and the wider document set for a first enquiry is covered in how to write an RFQ for a cleaning machine. Reach the team through the RFQ form.
Frequently asked questions
What documents do I need to import a PCBA cleaning machine?
Expect a commercial invoice, a packing list, a bill of lading or air waybill, a certificate of origin, an export declaration filed at origin, and an insurance certificate where the arrangement requires one. Your destination broker may ask for a technical description of the machine as well. Which party pays for each item depends on the delivery arrangement in the contract, so agree that before the booking.
How is a cleaning machine classified for customs?
By what the machine does and how it is built, as read against the nomenclature headings and the relevant section and chapter notes. A spray washer, a dry-ice blaster and a dust-removal unit are different articles even though all three are sold as cleaning equipment. Your broker settles the entry; the most useful thing a supplier can send is an accurate technical description with the model’s published specifications.
Does the HS code change when the machine is customized?
Customization that changes what the machine does — adding a process stage, changing the cleaning method, converting a batch unit into an inline unit — is worth raising with your broker, because function drives the heading. Cosmetic changes, voltage variants, basket sizes and fixture sets generally do not turn one kind of machine into another. Ask the question with the technical description in hand rather than after the container arrives.
Can spare parts ship in the same crate as the machine?
They can, and they should be listed separately on the packing list. Baskets, nozzles, filter cartridges and fixture sets are distinct articles with their own descriptions, and a consolidated crate that lists only the machine invites a question at inspection. Agree the accessory list with the order, then let the packing list follow it.
Who decides the HS code for my shipment?
Your broker or the importer of record settles the entry against the nomenclature headings and the relevant notes. What a supplier owes them is an accurate technical description with the model’s published specifications, so that the decision is made on machine data rather than on a marketing name.
