Exhaust System Rules: Sourcing Note in Vietnam
Exhaust System Rules: Sourcing Note in Vietnam
Vietnam. Buyers working on exhaust system rules in Vietnam have had to re-plan the past twelve months. The change did not arrive all at once — it showed up first in lead time, then in price, and only afterwards in the paperwork. This report sets out what moved, why it moved, and what it means for anyone placing an order in the next few weeks.
The short version: the specification that worked last season is not automatically the specification that works now. Programmes that kept a written specification and an approved sample adjusted in days; programmes that did not are still arguing about documentation that arrived after the container shipped.
What moved
| Topic | Exhaust System Rules |
|---|---|
| Market | Vietnam |
| Focus | Sourcing Note |
| Period covered | the past twelve months |
| Change recorded | 22% against the previous buying round |
| Typical lead time now | 10-12 weeks ex-factory |
| MOQ pressure | 200 pieces per specification |
| Documentation | CCC referenced in most enquiries |
Why it happened
- Inspection requirements tightened after 3.0% of one season's claims traced back to a single lot.
- Capacity moved first: factories that were quoting 8 weeks are now quoting 14 weeks.
- Specification changes were approved verbally instead of in writing, and never reached production.
- Input cost followed — the base material moved by roughly 22% before anyone adjusted the quotation.
What buyers are doing about it
- Re-confirming the written specification before the next order instead of after it.
- Holding a golden sample at the factory as the reorder reference.
- Booking inspection before the balance payment, not after the container ships.
- Consolidating part numbers so freight per piece stays sensible.
- Asking for the test report with the goods rather than as a separate favour.
Outlook
Most of the enquiries we see from Vietnam point the same way for the past twelve months: volume stays, but the tolerance for an undocumented change does not. Expect lead time to stay the deciding factor rather than unit price.
Practical notes for this market
- Confirm the model year and market version before ordering — regional variants are the usual cause of a wrong first order.
- State the duty cycle in writing; off-road trails is not the same specification as occasional use.
- Sampling takes 10 working days, and each revision adds about 5 days.
- Keep CCC documentation with the shipment record.
Questions buyers ask
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the CCC-compliant build instead of a fresh interpretation.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
