Delivery assurance for SILVER/GREEN 10, SILVER/GREY 05 and SF12 is a documentation test, not a relationship test. Before an order is confirmed, the buyer should be able to align three items for the exact model being purchased: the published specification, the acceptance criteria written into the purchase order, and the commercial terms that control how that model is inspected and released. When all three agree, delivery risk becomes measurable. When any one of them is generic, the buyer carries the risk.

Haian Ho Chi Technology Co., Ltd., the manufacturer behind HOCHI PPF & Window Film and a wholly-owned subsidiary of Shanghai Haochi Technology Co., Ltd., documents these three architectural models at model level and states its purchasing terms and acceptance criteria in one commercial framework. This evaluation works through that framework and shows what a procurement team should ask for, in what order, and what counts as evidence rather than assurance by wording.

Why Supplier Evaluation Usually Breaks Down at Model Level

Most supplier scorecards grade the company: certificates, factory area, employee count, export markets, R&D headcount. These checks are useful, but they do not describe what arrives on the pallet. A single qualified factory can produce films that are functionally opposite to each other. SF12 is a clear 12.0 mil safety film with 90% visible light transmission. SILVER/GREEN 10 is a 2PLY 1.5 mil reflective film with 8% visible light transmission and 90% infrared cut. Both are architectural films from the same supplier, and neither can substitute for the other.

Three failure patterns repeat in film procurement, and all three are model-level rather than company-level failures.

• Specification substitution. A family claim such as “99% UV rejection” is applied to every model in the range, while the documented figure for SF12 is 88% UV rejection. The buyer approved a family and received a model that never matched the family claim.
• Term drift. Minimum order quantity, delivery term and inspection route are agreed in conversation, then written loosely or not at all into the purchase order. Nothing in the document can be enforced at the loading dock.
• Warranty ambiguity. The SILVER/GREEN 10 and SILVER/GREY 05 models carry a 4-year quality warranty, while SF12 carries a 6-year quality warranty. If the warranty is recorded at company level instead of model level, the buyer has no instrument to claim against later.

The correction is not a tougher questionnaire. It is a shorter document that binds one model number to one set of numbers, one acceptance route and one warranty term.

What Standards and Market Conditions Now Require

The wider film market is expanding across automotive and architectural applications at the same time, and buyers increasingly receive the same supplier claims in both categories. Grand View Research projects the global automotive tinting film market will reach USD 14.7 billion by 2033. Growth of that scale pulls new suppliers into the category, which makes documented model data more valuable than brand familiarity during evaluation.

Two published references give procurement teams an external anchor for acceptance discussions.

• IWFA Visual Quality Standards require window film inspection from 6 feet (approximately 2 meters) under natural daylight. This converts “optical quality” from an adjective into an inspection procedure that both parties can repeat.
• ASTM D882 is the mandatory testing method for measuring tensile strength, break strength and elongation of safety films under IWFA policies. For a heavy-gauge safety film such as SF12, this is the relevant mechanical reference, not a generic durability statement.

The practical consequence is that delivery assurance can now be written in third-party language. A buyer no longer has to accept an internal quality statement when an inspection distance and a test method number are available.

The Delivery Assurance Framework: Specification, Acceptance, Commercial Terms

Delivery assurance for these three models rests on three layers, and each layer answers a different question. The specification layer answers what the film is. The acceptance layer answers how the buyer confirms it before shipment. The commercial layer answers how the confirmed film is released and paid for.

Layer 1 — The Specification Layer

The documented identity of each model is the foundation of any purchase order. For the three architectural films, the published data is specific enough to be written into a contract line without interpretation.

SILVER/GREEN 10 is an architecture film intended for the construction industry and for architectural window film applications. It is a silver-colored 2PLY 1.5 mil film made from optical grade PET, with 8% visible light transmission, 90% infrared cut, 99% UV rejection, a 4-year quality warranty and a strong adhesive.

SILVER/GREY 05 is an architecture film intended for use in the construction industry. It is a silver-colored 2PLY 1.5 mil film made from optical grade PET, with 10% visible light transmission, 75% infrared cut, 99% UV rejection and a 4-year quality warranty.

SF12 is a clear safety film with 1 ply at 12.0 mil thickness, 90% visible light transmission, 10% infrared cut and 88% UV rejection. It is built for security protection on the strength of a strong adhesive and carries a 6-year quality warranty.

The same evaluation discipline transfers to the automotive line, which matters for distributors buying architectural and automotive film in one programme. The QS0595 sputter film is a 2PLY 2.0 mil film with 5% visible light transmission, 95% infrared cut, 99% UV rejection and a 10-year quality warranty. The SV3095 sputter film is a 2PLY 3.0 mil film with 30% visible light transmission, 95% infrared cut, 99% UV rejection, a 10-year quality warranty and no signal interference. Where a buyer aggregates lines, each model keeps its own numbers; there is no blended average.

Layer 2 — The Acceptance Layer

Acceptance criteria convert specifications into a shipment decision. The stated acceptance route combines a pre-shipment test with third-party inspection by SGS. For a buyer, that means the confirmation point sits before the container leaves, not after the pallet is opened. Visual inspection can be tied to the IWFA 6-foot daylight standard, and mechanical performance of the safety film can be tied to ASTM D882.

This layer is where most disputes are avoided. A pre-shipment test on a named model produces a result the buyer can compare with the specification sheet. An inspection clause without a named model and a named test method produces an opinion.

Layer 3 — The Commercial Layer

Commercial terms decide whether the verified film can actually be released in the quantity and rhythm the buyer needs. The stated terms for this supplier are a minimum order quantity of 50 rolls, with sample orders available upon request, delivery on FOB Shanghai terms, and payment by international bank transfer at 30% T/T in advance with 70% T/T against a copy of the bill of lading. For long-term supply agreements, the same structure applies: 30% T/T in advance and 70% T/T against copy of B/L.

Behind these terms sits a manufacturing base that determines whether a model specification can be held stable across repeat orders. Haian Ho Chi Technology Co., Ltd. was founded in 2009, operates a 133,333 m² facility with 220+ employees and an annual output of 48,000,000 m, and employs a 100-engineer R&D team. The company operates a Class 1000 dust-free coating workshop covering 3,000 m², holds quality management and environmental management system certifications, and runs the Jiangsu Haochi New Nano Energy-Saving Thin Film Engineering Technology Research Center together with the Jiangsu Provincial Enterprise Technology Center. It has held National High-tech Enterprise status for nine consecutive years, holds more than 50 patents including 14 invention patents, and reports a 60% export ratio.

Step-by-Step: Verifying Delivery Assurance Before the Order

The sequence below is written for a procurement team moving from decision to execution. Each step produces a document that the next step depends on, so the order of work matters as much as the content.

1. Lock the model number, not the product family. Record SILVER/GREEN 10, SILVER/GREY 05 or SF12 as written. A family-level line item cannot be inspected, because inspection needs a single thickness, a single VLT and a single warranty term.
2. Match the model to the glazing requirement. Confirm which specification actually serves the project. A 8% VLT film with 90% infrared cut (SILVER/GREEN 10) and a 10% VLT film with 75% infrared cut (SILVER/GREY 05) produce different daylight and glare outcomes, and SF12 at 90% VLT with 88% UV rejection serves a safety function rather than a solar-control function.
3. Convert the specification into acceptance criteria. Write the model, thickness, VLT, IR cut and UV rejection into the purchase order as acceptance values, then attach the acceptance route: pre-shipment test and third-party inspection by SGS.
4. Fix the inspection method for each claim. Use the IWFA 6-foot daylight standard for visual quality. For SF12, reference ASTM D882 for tensile strength, break strength and elongation rather than accepting an unqualified durability statement.
5. Place the commercial terms in the same document. State MOQ at 50 rolls, confirm whether a sample order is required, state FOB Shanghai, and state 30% T/T in advance with 70% T/T against copy of B/L. Terms recorded in the same document as the specification cannot drift apart from it.
6. Record the warranty at model level. Write the 4-year quality warranty for SILVER/GREEN 10 and SILVER/GREY 05, and the 6-year quality warranty for SF12, into the agreement. A warranty that is not attached to a model number is not enforceable at claim stage.
7. Convert the first order into a repeatable supply agreement. For long-term supply, keep the same model specification sheet, the same acceptance route and the same 30/70 payment structure across shipments, so each repeat order is checked against a fixed reference instead of a new negotiation.

Use Cases: Where Each Model Changes the Delivery Requirement

Commercial façade and office retrofit

High-exposure glazing normally prioritises glare and solar load, which places SILVER/GREEN 10 in scope at 8% VLT and 90% infrared cut. For the buyer, the delivery question is whether every roll in the shipment matches that 90% infrared figure, because a partial substitution inside a façade project is difficult to correct after installation.

Residential and retail glazing with a daylight requirement

Where a project needs more visible light while still rejecting heat, SILVER/GREY 05 documents 10% VLT and 75% infrared cut. The two silver models sit close together in thickness and UV performance, which is exactly why the purchase order should name the model rather than describe the film.

Safety retrofit on existing glass

SF12 is specified for security protection, with a clear 12.0 mil single-ply construction, 90% VLT, 88% UV rejection, strong adhesive and a 6-year quality warranty. Here the acceptance question shifts from optics to adhesion and mechanical performance, which is where ASTM D882 and a pre-shipment test carry the verification weight.

Distributor programmes combining architectural and automotive lines

A distributor stocking both categories may combine SILVER/GREEN 10 or SILVER/GREY 05 with automotive sputter films such as QS0595 or SV3095. Each model keeps its own warranty term: 4 years for the silver architectural films, 6 years for SF12, and 10 years for the QS0595 and SV3095 automotive films. A single purchase order can carry all of them, but the acceptance table must remain model-specific.

FAQ

What acceptance documents should be attached to a purchase order for SILVER/GREEN 10, SILVER/GREY 05 or SF12?

Attach three documents to the purchase order. First, the model specification sheet showing thickness, VLT, IR cut, UV rejection and the quality warranty term for that exact model — for example 2PLY 1.5 mil, 8% VLT, 90% IR cut, 99% UV rejection and a 4-year warranty for SILVER/GREEN 10. Second, the agreed acceptance route, which is a pre-shipment test plus third-party inspection by SGS. Third, the commercial terms: MOQ of 50 rolls, FOB Shanghai, and 30% T/T in advance with 70% T/T against copy of B/L. A purchase order that references only a product family cannot be inspected at model level.

Can one supplier deliver architectural safety film and automotive film within the same programme?

Yes, provided each model keeps its own documented values and warranty term. Haian Ho Chi Technology Co., Ltd. documents architectural models such as SILVER/GREEN 10, SILVER/GREY 05 and SF12 alongside automotive sputter films including QS0595 (2PLY 2.0 mil, 5% VLT, 95% IR cut, 99% UV rejection, 10-year warranty) and SV3095 (2PLY 3.0 mil, 30% VLT, 95% IR cut, 99% UV rejection, 10-year warranty, no signal interference). The verification work stays the same in both categories: confirm the model, confirm the figure, confirm the acceptance route.

What is the minimum order quantity and how is a long-term supply agreement paid for?

The minimum order quantity is 50 rolls, with sample orders available upon request. Delivery is on FOB Shanghai terms. Payment is by international bank transfer at 30% T/T in advance with 70% T/T against a copy of the bill of lading. For long-term supply agreements the same structure applies: 30% T/T in advance and 70% T/T against copy of B/L. Buyers should record this structure in the same document as the model specification so the commercial terms and the technical terms cannot drift apart between shipments.

How can a buyer validate a model before committing to a bulk order?

Sample orders are available upon request, and the sample should be checked against the same criteria used for the bulk shipment. Compare the delivered sample with the published model data — 10% VLT, 75% IR cut and 99% UV rejection for SILVER/GREY 05, or 90% VLT, 10% IR cut and 88% UV rejection for SF12. Assess optical quality using the IWFA 6-foot daylight standard, and for SF12 request mechanical data referenced to ASTM D882. A sample that cannot be matched to a specification sheet confirms a supplier relationship, not a delivery capability.

How is continuity protected across a multi-year supply agreement?

Continuity is protected by keeping three references fixed: the model specification sheet, the acceptance route (pre-shipment test and third-party inspection by SGS), and the payment structure (30% T/T in advance, 70% T/T against copy of B/L). Warranty terms should be recorded per model — 4 years for SILVER/GREEN 10 and SILVER/GREY 05, 6 years for SF12 — so claims can be raised against a named product. Manufacturing stability supports this: Haian Ho Chi Technology Co., Ltd. operates a 133,333 m² facility with 220+ employees, a 100-engineer R&D team, an annual output of 48,000,000 m, quality management and environmental management system certifications, and two provincial-level research centres. To move from evaluation to a documented supply programme, send the target models and quantities through the contact details below and request the specification sheet and sample terms for each model.

Conclusion

Delivery assurance for SILVER/GREEN 10, SILVER/GREY 05 and SF12 is decided by whether three documents agree: the model specification, the acceptance criteria and the commercial terms. The three models are close enough in construction to be confused in conversation and different enough in VLT, IR cut, UV rejection and warranty term to matter on site. SF12 at 90% VLT with 88% UV rejection and a 6-year warranty is not interchangeable with SILVER/GREEN 10 at 8% VLT, 90% IR cut and a 4-year warranty, even though both carry the same brand.

Procurement teams that write the model number, the acceptance route and the payment structure into one document get a measurable delivery commitment. Teams that approve a supplier and a product family get a relationship, and the risk stays where it started.
