Quality Control & FBA Prep in China

Catch Product Issues Before They Become Costly

A product can look fine in factory photos and still arrive with defects, incorrect labels, damaged packaging, missing components, or compliance issues.

When products leave China before those problems are identified, fixing them can become far more expensive. You may need to pay for return shipping, US or overseas rework, relabelling, storage, disposal, replacement inventory, customer refunds, or marketplace-related remediation.

Our quality control and FBA prep services help you identify issues while your goods are still in Shenzhen—before they are sent to Amazon, another 3PL, retail partners, or end customers.

We inspect the inventory that arrives at our warehouse, document discrepancies against your agreed requirements, and give you the information needed to decide what happens next.

China Quality Control and FBA Prep Services

Product Inspection and Quality Control

We inspect incoming products against your approved specifications, purchase order, reference sample, or product instructions.

Depending on your chosen inspection scope, checks can include:

• Unit quantity verification

• Visible defect inspection

• Colour and appearance review

• Packaging-condition checks

• Product dimension checks

• Barcode and label verification

• Basic functionality testing where applicable

• Component, accessory, and insert checks

• Carton-condition review

• Photo documentation of issues found

If we find a problem, we provide a structured report with photographs and a clear description of the issue. You can use this information to request corrective action from your supplier, authorize rework, update the product, or hold the affected inventory.

FNSKU Labelling and Relabelling

Correct labelling is essential for Amazon FBA inventory. We apply FNSKU labels according to your approved instructions and verify that labels are positioned correctly and remain scannable.

Our FNSKU labelling service can include:

• Printing and applying FNSKU labels

• Covering existing manufacturer barcodes where required

• Replacing incorrect or damaged labels

• Checking barcode placement

• Verifying scan readability

• Applying labels to individual units, bundles, cartons, or packaging

• Preparing products according to the shipping plan you provide

If your supplier has applied the wrong label, used an outdated barcode, or left products without the correct Amazon identifier, we can relabel products before they are shipped onward.

Poly Bagging, Bubble Wrap, and Protective Packaging

Products often require additional protective packaging before they are shipped to Amazon or customers. We prepare goods according to your confirmed packaging instructions and the applicable marketplace requirements.

Preparation options can include:

• Poly bagging

• Suffocation-warning labels where required

• Bubble wrapping

• Foam protection

• Air pillows and void fill

• Tamper-evident packaging

• Protective sleeves

• Moisture protection and desiccants where appropriate

• Sealing loose components

• Securing fragile products for transit

We assess the packaging requirement based on your product, sales channel, shipment method, and destination. Protective packaging should reduce avoidable transit damage while keeping dimensional weight and fulfillment costs under control.

Bundle and Set Assembly

Turn individual products into ready-to-sell bundles, gift sets, multipacks, subscription boxes, promotional kits, and Amazon-compliant sets.

We can assemble products according to your approved instructions, including:

• Combining multiple SKUs into one sellable unit

• Building multipacks and value packs

• Adding “Sold as Set” labels where required

• Inserting accessories, manuals, cards, or promotional materials

• Applying a new barcode or FNSKU to the completed bundle

• Packaging the final set for storage and dispatch

• Verifying the correct contents before shipment

Bundle assembly in Shenzhen can simplify your supply chain when components come from different factories or when your products require final assembly before fulfillment.

Repackaging and Product Relabelling

If products arrive with damaged, unsuitable, incomplete, or non-compliant packaging, we can help prepare them for the next stage of your supply chain.

Our repackaging services may include:

• Replacing damaged retail boxes

• Applying corrected labels

• Removing outdated stickers

• Adding compliant packaging inserts

• Replacing packaging with your approved branded materials

• Preparing products for international fulfillment

• Repacking products into protective outer packaging

• Updating language labels or product information supplied by your brand

• Preparing cartons for Amazon FBA, retail, wholesale, or D2C fulfillment

We will confirm the required materials, labour scope, and price before rework begins.

QC Reports With Photo Evidence

Every quality-control workflow should give you visibility—not vague confirmation that a shipment was “checked.”

Our QC reporting can include:

• Quantity received

• Quantity inspected

• Defect count and defect rate

• Clear photographs of issues found

• Packaging and carton images

• Label and barcode images

• Notes on visible discrepancies

• Recommendations for next steps

• A record you can share with your supplier

These reports help you make faster decisions while products remain in China and while supplier communication is still practical.

Prepare your inventory before it leaves China.

Our FBA prep services are designed for sellers shipping products from Chinese factories to Amazon fulfillment centers or to an intermediary destination. We follow the product and shipment instructions you provide, then prepare cartons for dispatch.

FBA prep can include
