Version the brief
Use the same revision for each supplier and keep optional substitutions separately identifiable.
Dunlop is an independent China procurement service. It operates independently of the Dunlop tire manufacturer and brand owner and holds no authorized dealership.

A buyer can receive three unit prices for the same nominal tire size and still have three different offers. One may quote a different speed rating. Another may exclude mixed-container loading or use a different named port. The desk puts those differences next to the supplier's price and asks the buyer to approve departures from the brief.
Separate the supplier's claim, the evidence it provided and the buyer's decision.
The buyer signs off on the fitment and order. The supplier remains responsible for manufacture and product documentation. Laboratories and inspection providers report within their agreed scope. The buyer's appointed broker and carrier handle clearance and carriage.
Use the same revision for each supplier and keep optional substitutions separately identifiable.
Match any document to the supplier site, model or SKU, test conditions and target market.
Keep changes in size mix, approved samples and packaging basis visible before release.

A replacement program can carry near-identical sidewall descriptions on different carton lines. Keep the load index, speed rating and destination label with the SKU. Receiving can then compare the physical marks against the approved packing record and isolate unexplained substitutions.

For a serviceable bearing, compare bore, outside diameter and width alongside seal lip orientation and bearing preload instructions. Record the kit hardware and tools needed at each location. An integrated hub unit can reduce assembly steps where the platform supports it, while a serviceable bearing retains repair flexibility.
A size list, vehicle requirement or OE cross reference gives the desk a basis to clarify your request.
