What every plastic products inspection covers
Most plastic consumer goods are moulded: injection moulding for containers, lids, pen barrels and caps; blow moulding for bottles; compression moulding for melamine. A mould makes the same part thousands of times, so most defects are either systematic, coming from the tool or the material, or random, coming from a process that drifts. An inspection is built to tell which. Every inspection covers:
- Quantity and assortment by item, colour and pack against the purchase order, with cartons opened at random.
- Material identity. Resin type and grade from the factory's purchase records and bags in the store, compared with the grade named on your test reports. Recycling codes moulded into the part checked against the material.
- Part weight. Sampled parts weighed against the approved sample. A lighter part often means thinner walls or a cheaper filled compound.
- Moulding defects. Flash, short shots, sink marks, warpage, weld lines, silver streaks, black specks and gate marks.
- Colour. Parts compared with the colour standard in a light booth; lids checked against bases, because they often come from different moulds and masterbatch lots.
- Dimensions and fit. Critical dimensions measured with callipers and gauges; lids, caps and parts assembled.
- Function. Leak, seal, click, write and drop tests, as the product needs.
- Marks and claims. Food-contact symbols, "BPA free", dishwasher and microwave claims, age warnings and origin marking against the evidence.
Sample sizes follow ISO 2859-1; see the AQL guide. The report ends in one verdict: Cleared to load, Hold or Not cleared.
How the checklist changes by product
| Product | Main risk | What the inspector adds |
|---|---|---|
| Plastic houseware and melamine | Food-contact test reports that do not match the material used; leaking lids | Resin and masterbatch traced to the test report, inverted leak test, drop test, claim and symbol check, melamine surface and decal check |
| Writing instruments and stationery | Pens that skip or leak; caps a child could inhale | Write test against the golden sample, cap vent check, click and clip function, assortment count per pack, art-material labelling |
| Rigid plastic packaging | Neck and cap dimensions that leak on the filling line | Neck finish gauging, capacity, wall thickness, cap torque, top load, tethered cap function |
| FIBC bulk bags | Bags failing below their rated load | Covered on its own page under technical textiles: top-lift test, loops, seams and markings |
Test reports and what the inspector can verify
For plastic goods that touch food or are used by children, the legal question is chemical: what migrates from the plastic into food, or what a child can be exposed to. That is answered in a lab, not at the factory. A report is only useful if it was made on the same material the factory is using now, and that is where an inspection helps.
At the factory, the inspector can:
- Read the resin and masterbatch bags in the store and the purchase invoices, and compare grade names and suppliers with the ones on your test report and declaration of compliance.
- Check whether regrind or recycled material is used, and how much. Post-consumer recycled plastic for food contact needs an authorised recycling process in the EU under Regulation (EU) 2022/1616.
- Weigh parts and check colours against the tested sample, because a change in either can mean a different compound.
- Pull and seal random samples from the finished lot for an ISO/IEC 17025-accredited lab, through lab testing coordination.
Migration tests, heavy metals, phthalates and BPA are lab results. We check the lab report against the goods; we do not run these tests ourselves.
Market rules that shape the checklist
| Market | Rule | What it means at the factory |
|---|---|---|
| EU | Regulation (EC) 1935/2004 and Plastics Regulation (EU) 10/2011 | Only authorised substances; migration limits; a declaration of compliance for each plastic food-contact article. See EU 1935/2004 and LFGB |
| EU | Regulation (EU) 2024/3190 on bisphenol A | BPA banned in food-contact materials; the main transition periods ended on 20 July 2026, with some running to 2028. Polycarbonate food-contact items need checking |
| EU | Packaging and Packaging Waste Regulation (EU) 2025/40, applies from 12 August 2026 | Heavy-metal limit now; recycled-content targets for plastic packaging from 2030 at the earliest |
| EU | Single-Use Plastics Directive (EU) 2019/904 | Plastic caps on beverage containers up to 3 litres must stay attached, since 3 July 2024 |
| US | FDA 21 CFR Part 177 (indirect food additives: polymers) | Resin grades that meet the listed regulation for the food and use. See FDA food contact |
| US | CPSIA; LHAMA (art materials) | Lead limits for children's products; chronic-hazard labelling of art materials. See CPSIA |
| California | Proposition 65 | Warnings for listed chemicals such as BPA and some phthalates. See Prop 65 |
Where plastic products are made in India
Plastic processing in India is spread across Gujarat, Maharashtra, the Union Territory of Dadra and Nagar Haveli and Daman and Diu, Delhi NCR, Tamil Nadu and many other states, in units from small moulding shops to large automated plants. We have not found an official source that names a verified export cluster for plastic houseware, pens or rigid packaging, so we do not name towns on this page. What matters for an inspection is the factory's own moulding, tool maintenance and material control.
According to IBEF, using data from DGCI&S and the Plastics Export Promotion Council (PLEXCONCIL), India's plastics exports were US$12,468.7 million in FY2025-26, against US$12,501.0 million in FY2024-25. Within that, consumer and houseware products were US$872.6 million (up 10.4%), and writing instruments and stationery fell 11.9% (IBEF, page updated July 2026). Raw materials and films make up much of the total.
Booking a plastic products inspection
Clear To Load is based in Jodhpur, with inspectors in Jaipur, Saharanpur, Moradabad, Delhi NCR and Kolkata, and covers every city in India. An inspection costs US$249 per man-day; travel outside our inspector base cities is charged at actual cost. See pricing.
For a new mould or a new supplier, a pre-production inspection checks the resin, masterbatch and first-off parts against the approved sample before the full run. A pre-shipment inspection then checks the finished lot. Send the approved sample, drawings with critical dimensions, colour standards and your test reports. The product pages below cover each type in detail.
