The Product Specification Pack: What to Define Before Sourcing in China

The documents and acceptance criteria needed to turn a product idea into a controllable sourcing and manufacturing requirement. This guide explains what to define, verify and document before committing funds or authorising the next step.

Key decisions before you start

• Describe intended use, users, environment, dimensions, performance, materials and foreseeable misuse.
• Identify critical-to-quality characteristics, tolerances and the method used to verify each requirement.
• Include packaging, labels, languages, compliance, accessories, spare parts and shipment constraints.

Recommended process

• Create one indexed specification with revision control instead of requirements scattered across messages.
• Review the pack with engineering, quality, compliance, logistics and commercial stakeholders before quotation.
• Ask the supplier to mark every exception and sign the approved revision before sample production.

Risks and common mistakes

• Words such as high quality, waterproof or strong are not measurable acceptance criteria.
• An approved visual sample cannot replace material, performance and safety requirements that remain undocumented.

Buyer checklist

• ☐ Every requirement has an owner and verification method.
• ☐ Drawings and bill of materials use consistent references.
• ☐ The production and inspection revisions are identical.
• ☐ Changes require written approval and an updated revision.

What this looks like in practice

Panda United can verify the supplier’s evidence in China, coordinate the relevant actions and report directly to the European buyer. The scope is agreed in writing so that responsibilities, deliverables and remaining risks remain visible.
