Drain Blaster Pre-Shipment Inspection Checklist for Importers
A pre-shipment inspection can check the kit, labels and packing before the order leaves. Agree its scope and obtain a fee quotation for the actual location, quantity and test plan. Keep the approved sample and order list available to the inspector.
This checklist is what we recommend to buyers of manual, electric and rechargeable air drain blasters. Use it for your own inspector, a third-party agency or our final check.
Before the inspection: agree the standard
An inspection is only as good as the reference it is checked against. Before production, agree and sign:
- The approved sample, kept by both sides, including colour, logo and every head in the kit.
- Packaging artwork: retail box, manual, labels and carton marks. Several of our models, including WC-P020, WC-P021 and WC-P022, are offered with a Chinese or an English retail box, so state which one you want.
- Sampling and acceptance criteria. Agree a sampling plan with the inspector, including appearance and function checks, defect definitions and the treatment of critical defects. Record the chosen standard, inspection level and acceptance rules before production.
- Pressure and safety details for the model: working pressure, safety valve and pipe diameter are confirmed in writing with the quotation.
The checklist
| Check | How | Pass when |
|---|---|---|
| Kit contents | Open sample cartons; count every item against the packing list | All items specified for the approved kit are present |
| Appearance | Inspect in daylight at arm’s length | No cracks, flash, scratches or colour mismatch against the sample |
| Logo and labels | Compare with approved artwork | Correct position, colour and wording; barcode scans |
| Threads and fit | Check each selected connection against its fitting instructions | Runs smoothly, seats fully, no wobble |
| Pressure hold | Use the approved model-specific pressure, duration, fixture and operator procedure | Recorded result meets the agreed acceptance limits |
| Release and seal | Have a qualified inspector use the approved release-and-seal test setup | Assembly meets the selected model’s documented test criteria |
| Stainless barrel | Inspect the surface and construction using the approved handling procedure | Smooth seam, no cracks, dents or sharp edges |
| Electric / rechargeable | Follow the model-specific functional procedure and inspect the supplied charger labels | Function and electrical specification match the approved unit and destination requirements |
| Carton | Check count, marks, weight and condition; drop test if agreed | Count and marks correct; no crushed or burst cartons |
Defects to classify in advance
Inspectors argue less when the defect list is agreed before they arrive. A typical split for drain blasters:
- Critical: a barrel or neck crack, a missing or blocked safety feature, an electrical fault, a charger with exposed live parts.
- Major: pressure leak, a head that will not seal, a missing kit item, wrong box language, wrong plug type, a logo in the wrong place.
- Minor: small scratches, slight flash that does not affect function, minor print blemishes.
Our article on how air drain blasters are made sets out material, assembly and inspection details to confirm for the selected model.
Cordless and electric models: extra checks
For WC-PE005, WC-PE006, WC-PE007, WC-PE003 and WC-PE001, add:
- Battery documents. Ask the forwarder for the document list applicable to the selected battery, equipment configuration and shipping route. Confirm document availability against the exact battery reference before shipment.
- Charger and plug. Confirm the charger input and destination supply requirements, together with the output, connector and polarity specified for the selected tool and battery.
- Battery removability. For EU sourcing, review the selected appliance and any applicable exceptions against the Commission guidance on Article 11. Its removability and replaceability obligations apply from 18 February 2027. Confirm the assessment for the actual product design before ordering.
- Markings. Identify the safety, conformity and waste-related markings applicable to the exact product and destination. Match the supporting documents to the selected model and responsible entities.
Labels for the EU market
For EU orders, confirm the manufacturer and relevant importer or responsible economic operator, product or batch identification, contact information and instruction language. Review the official GPSR overview and applicable product-specific rules when approving the labels.
Cartons and loading
Use the selected model’s current quotation and packing list. As catalog references, WC-P020 lists 12 pieces per carton and WC-P022 lists 16 sets; confirm the configuration before shipment. Check model, quantity, carton marks, weight and agreed protection for the chosen route.
Agree the inspection report before ordering
Specify the report, photos and test records you need, and confirm what can be provided for the selected order. Agree whether a buyer-appointed or third-party inspector will attend, the scope and any fees. MOQ is confirmed by model and configuration in the quotation.

FAQ
How many drain blasters should be checked before shipment?
Agree the sample size and sampling method with the inspector for the actual order. Record which appearance, assembly and function checks use that sample, together with the acceptance criteria.
Which AQL should we use for drain blasters?
Choose the acceptance criteria with the inspector and record how critical, major and minor defects will be handled. Set these rules before production rather than adopting one default across every model.
What documents does a cordless drain cleaner need for shipping?
Ask the forwarder which battery and transport documents are required for the selected equipment, battery reference and route. Confirm availability before the shipment is booked.
Does an air drain blaster need a CE mark?
Assess the exact model against the applicable EU product rules. A manual mechanism alone does not settle whether CE legislation applies. Use the official CE-marking guidance and request the relevant model-specific assessment and documents.
