A crated machine is described by its documents before anyone sees it. AI-generated illustration.

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

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.

DocumentIssued byMachine fact it must matchWhere it breaks
Commercial invoiceSellerModel designation and what the machine doesInvoice says “cleaning machine”, datasheet says inline PCBA washer
Packing listSeller or packerPacked dimensions and gross weightMachine outline copied instead of crate outline
Bill of lading or air waybillCarrierPackage count and gross weightCount changes after crating, nobody updates the list
Certificate of originIssuing bodyCountry of manufactureRequested after the vessel is booked
Export declarationSeller’s brokerClassification, value and quantityFiled before the final packing list exists
Insurance certificateSeller or buyer, per agreementInsured value and routeIssued 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:

MismatchWho catches it firstWhat it delays
Gross weight vs net weightForwarder, at bookingFreight quote, then container loading
Crate outline vs machine outlineTrucking company, at pickupVehicle assignment and door clearance
Function description vs classificationDestination broker, on entryRelease of the container for examination
Accessories missing from the entryCustoms, at inspectionThe whole consignment, not just the box

Source: CHUANGQI shipment preparation records, 2026-10. The delay each mismatch causes depends on the port, the route and the broker’s backlog.

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.
